Concept of KiTEC Pipe

KiTEC is an aluminium and polyethylene composite that combines the best features of both materials to form a pipe that is light, strong and does not support corrosion. By combining the two materials, KiTEC pipe avoids the unaccepted thermal expansion and deformation of plastic pipe. At the same time it retains the flexibility, frost resistance and ease of use associated with plastic.

Functional properties of various layers are as follows :
Plastic (PE) Layers :

PE layers of composite pipe provide all the advantages of plastic pipes such as,

  • Corrosion resistance
  • Chemically inert
  • Smooth surface for better flow properties
Tie Layers :

The tie layers have the following functions :

  • To perfectly bond the metal and plastic
  • Absorb eventual shifting movements between plastic & metal, likely to occur in opposite directions
  • To give the Composite pipe the advantages of a single component pipe
Aluminium (Metal) Layer :

In addition to all the inherent advantages of plastic pipes the inclusion of the metallic pipe gives Composite pipe the qualities of metal, namely :

  • Absolute tightness
  • Mechanical resistance to deformation
  • Dilation within reasonable limits
KiTEC Composite Pipe

KiTEC Composite Pipes conform to IS : 15450-2004 "Standard Specification for Polyethylene/ Aluminium/ Polyethylene (PE-AL-PE) Composite Pressure Pipe."

KiTEC Composite Pipes are having pressure rating of 13.8 Kg/Cm2 at 23oC. and 11.0 Kg/Cm2 at 60oC. KiTEC Composite Pipe can safely be used for 6 Kg/Cm2 pressure at 80oC working temperature. Short term excursions to 95oC. will not affect the overall performance. Design life span for KiTEC Composite Pipe is in excess of 50 years

KiTEC Pipes for Air Conditioning:

Plastic is a fascinating and interesting material indeed, but with it's proneness to creeping and it's significant dilation, plastic alone is in most cases not ideally suited and only restrictively operational in pipe nets. Thus, in plastic pipes, the rated pressure of pipe reduces drastically with increase in design life span at specified operating temperature. At the same time, the life of the pipe reduces drastically with the increase in operating temperature.

KiTEC composite pipes have these properties balanced to satisfying levels.

In addition to this, better Insulating property as compared to conventional metal pipes and suitability of the pipe for use at sub-zero temperature up to -40oC temperature gives KiTEC an added dimension for the applications associated with Air Conditioning.

KiTEC Pipe for Radiant Heating System
The basic advantage of radiant heating system over conventional heating system is better temperature distribution leading to 30% saving in energy. Forced air systems distribute heat unevenly with hot air rising to the ceiling. This creates a "Warm Head – Cold Feet" sensation which is not what the body likes.

Warm floors allow you to heat the extremities – feet, legs – and provide you with greater personal comfort at a reduced room temperature.

KiTEC Pipes for Cooling Systems
Fan Coil Units : The Fan Coil Unit (FCU) is a sheet metal cabinet that houses a Chilled Water Coil constructed out of copper tubes and aluminium fins, a Blower with motor and an Air Filter. Fan Coil Units are generally used where multiple areas (example, hotel rooms) are to be cooled independently, using a central air-conditioning plant. The water is chilled centrally and pumped to various parts of the building through insulated pipes. The chilled water enters the FCU, where heat exchange takes place between the room air and the chilled water in the coil. Air is passed over the coils using a three speed blower motor, mounted in the FCU.

Warm floors allow you to heat the extremities – feet, legs – and provide you with greater personal comfort at a reduced room temperature.

The same room with forced air heating may require air to be heated as much as 20o-30o hotter in order to provide the same level of overall warmth to your body.

KiTEC piping is being exclusively used for floor radiant heating system for following properties:

  • Flexibility
  • Ease in installation
  • Low expansion and contraction
  • High impact strength
  • Malleable
  • 100% impermeable to oxygen
  • High thermal strength
  • virtually maintenance free
  • Joints which can withstand temperature changes as well as pressure changes

Normally 1216 and 1620 KiTEC pipes are used. Loop length is a function of room size, manifold location and supply/return temperature differential. The maximum recommended length of continuous tubing from a supply and return manifold arrangement should be as follows:
Nominal Size

KiTEC Pipes for Cooling Systems

Fan Coil Units:
The Fan Coil Unit (FCU) is a sheet metal cabinet that houses a Chilled Water Coil constructed out of copper tubes and aluminium fins, a Blower with motor and an Air Filter. Fan Coil Units are generally used where multiple areas (example, hotel rooms) are to be cooled independently, using a central air-conditioning plant. The water is chilled centrally and pumped to various parts of the building through insulated pipes. The chilled water enters the FCU, where heat exchange takes place between the room air and the chilled water in the coil. Air is passed over the coils using a three speed blower motor, mounted in the FCU.

The air speed can be controlled by choosing the blower motor speed, from a selector switch, in the conditioned space. A thermostat is also mounted in the air-conditioned space. The thermostat controls a solenoid valve that closes when the desired temperature is reached, thereby shutting off the flow of chilled water into the FCU water coil. Once the temperature in the room rises the thermostat activates the solenoid valve which opens allowing the chilled water to flow into the coil again. The temperature of chilled water is ranging from 5 to 7 degree C.

KiTEC Pipe for Fan Coil Units:
The piping is required to be provided from central air-conditioning plant to each fan coil unit. A return water line is also required. The pipe line to fan coil unit is pressurized pipe and return line is at lower pressure and termed as drain line. From main, KiTEC pipe is used. Generally Male thread connectors / female thread connectors are required only unless an additional connection is given from this line. In such case, a tee will be required. Fittings for Fan Coil Units:
Brass Internal sealing, Composite Internal sealing as well as external sealing fittings can be used for piping of fan coil units. It is necessary that the installation procedure as recommended is followed.

KiTEC Pipe for Split Air Conditioners:
KiTEC provides excellent chemical resistance for freon gas. It can be used for pressure as well as delivery piping for split air conditioners.

Fittings for Split air conditioners: Brass Internal sealing fittings must only be used for piping. It is necessary that the installation procedure as recommended is followed.

Many a times, threaded joints are avoided. In such cases, KiTEC to copper connection should be used. This fitting is having one end suitable for ferrule joint with copper and other end is for jointing of KiTEC pipe.

KiTEC Pipe Avoid condensation: KiTEC composite pipes provide an increased resistance to the onset of condensation or pipe sweating in a air conditioning application. Metal pipe in the same situation will condense moisture on the outside pipe surface or sweat far sooner than KiTEC. The graph provides a comparison.

The graph shows that for given internal fluid temperature and relative humidity copper pipe sweats well before any size of KiTEC pipe. It should be noted, that 2025 KiTEC pipe provides the greatest resistance, while the 1216 KiTEC provides somewhat less.

Minimize the temperature rise in chilled water:
As KiTEC is bad conductor of heat, it requires lesser insulation as compared to equivalent metal pipes. As a thumb rule, the insulation requirement is considered to be 50% of the metal pipes.

Work in tight spaces:
KiTEC can be installed in walls and ceilings or surface mounted. It can be supported horizontally or vertically on 8 foot centers because its stiffness and expansion rate is similar to copper's. KiTEC is easily formed into curves, sets by hand and only requires bending springs when forming tight bends down to radius equivalent to 5 times the diameter of pipe.

KiTEC permanently holds whatever shape it is formed into and does not need additional clips or brackets to retain the shape of bends or curves. Hence it is easier to work with KiTEC for the lines which are running over the sealing for connection with FCUs which are required to be installed at strategic locations.

KiTEC for Chemical Handling

Excellent Chemical Resistance:
KiTEC Piping System offers, perhaps, the best chemical and corrosion resistance of any plastic used in the manufacture of pipes. The polyolefin family of plastics - PE and PEX included - is renowned for it’s toughness, long service life and resistance to deterioration in the most extreme environments. In addition to this, with Aluminium layer it resists the swelling leading to very good chemical resistance for liquid hydrocarbons such as diesel, petrol, kerosene and fuel oils.

Low Expansion and Contraction:
KiTEC’s aluminum core controls the amount of expansion and contraction in the pipe. In fact although KiTEC looks like a plastic pipe its expansion rate is very similar to copper’s so you don’t have to worry about building in costly and time consuming pipe offsets. In addition to this, while laying the pipe line on racks, particularly in case of industrial piping, the thermal stresses developed are very low resulting in lower stresses on supporting structure. No special clamping arrangements are required to be provided.

Support Spacing and overhang:
With better structural strength due to aluminium layer, as compared to PE pipes, KiTEC provides more versatility for in plant piping. Overhang of 1.5 meters can be safely provided for most of the chemicals with specific gravity being equal or lesser than 1. As a thumb rule, this distance can be altered in the ratio of the specific gravity of fluid. Hence for Phosphoric Acid, having specific gravity of 1.5, the overhang can be 1 meter.

Performance at elevated temperature:
The reduction in basic strength with the rise in temperature is less as compared to other plastic pipes. Hence, KiTEC piping system gives superior service at elevated temperatures up to 80 deg. C. as compared to other conventional plastic pipes.

KiTEC for Gaseous Fluids

Plastic pipes are permeable to gases. Composite pipe with Aluminium barrier layer is the best option as an alternative to other plastic pipes to reduce the gas permeation.

KiTEC pipes provides complete impermeability and at the same time offers all the advantages associated with plastic pipes such as corrosion resistance, and ease in installation.

KiTEC Brass fittings, when used with KiTEC pipe, ensure leak-proof joints at a pressure as high as 20 bar.

KiTEC piping system is widely accepted for various gaseous fluid handling systems such as,

  • Compressed air lines for industrial applications
  • Compressed air lines in dental hospitals
  • Natural Gas/LPG distribution for domestic and commercial installations
  • LPG distribution for poultry farm heating systems with gas brooders

KiTEC Composite Pipes as Cable Conduits

Shielding Effectiveness
KiTEC COMPOSITE PIPES are very effective as conduit, specially for data transmission, telecommunication and signal cables. Its uniqueness is in its three layer construction, incorporating a welded sealed aluminium tube providing the very latest method of EMI screening covered both internally and externally with a layer of Polyethylene. This gives the product comparable strength to that of a metal conduit with the flexibility of a plastic conduit.

Shielding effectiveness (attenuation in dB) is a measurement of the ratio between the external environment field strength and that field strength measured after passing through any material. This is recorded in a logarithmic scale

KiTEC COMPOSITE multi layer conduit systems are designed to absorb and reflect emitted radiation from sources of interference.

The shielding effectiveness of KiTEC COMPOSITE PIPING SYSTEM is highly effective throughout the entire frequency range, and will provide protection from interference for data, telecommunication and signal cables and is far superior in comparison to any other product currently available.

Cost Savings
This is supplemented by the cost savings that can be made during installation and the greater flexibility of the range.

With KiTEC COMPOSITE PIPES, its unique construction and smooth internal bore makes the stripping of cable insulation a thing of the past, compared to steel conduit. Add to this the greater lengths through more bends which can be achieved without stretching the cables, the pulling of cable could not be easier.

KiTEC COMPOSITE PIPES is a simple tubing product which can be installed with no mess, minimal wastage and in a fraction of the time taken for conventional systems, for cable protection, screening, fire protection and halogen free applications.

WARNING: The aluminium tube is not suitable to be used as a protective conductor.

Salient Features - Physical Properties
Malleable

The unique feature of KiTEC is it’s malleability. KiTEC is easily formed into curves, sets by hand and only requires bending springs when forming tight bends down to radius equivalent to 5 times the diameter of pipe. Unlike plastic plumbing pipes, KiTEC permanently holds whatever shape it is formed into and does not need additional clips or brackets to retain the shape of bends or curves.

Fewer Fittings - Malleable and Stays in Shape

1) The unique feature of KiTEC is it’s malleability. KiTEC pipe can be formed by hand leading to fewer fittings, fewer joints and faster installation.
2) Small diameter KiTEC is easily formed into curves, sets by hand and only requires a bending springs when forming tight bends down to radius equivalent to 5 times the diameter of pipe.
3) Unlike plastic plumbing pipes, KiTEC permanently holds whatever shape it is formed into and does not need additional clips or brackets to retain the shape of bends or curves.

KiTEC piping systems don’t corrode

Will never pit or develop pin holes from aggressive water leading to premature failure.

No scale build up to reduce flow

Soluble encrustants, such as calcium carbonate do not readily precipitate onto the smooth walls of KiTEC pipes. In addition there are no reduction in flow areas and flow coefficients as the pipes age. 

Flame/Smoke Rating

KiTEC pipe has a Flame Spread of 5 and a Smoke Development of 5 as per ULC-S102.2. The ratings meet most building code requirements allowing for the use of KiTEC in high-rise construction as well as in return air plenums and vertical shafts. 

Permeation

KiTEC’s aluminum core acts as a permeation barrier against entry of contaminants, and limits oxygen permeation to virtually zero. Permeation is the molecular transport of chemicals, from the soil surrounding the pipe, through the pipe wall and into the fluid being carried within. Permeation may have adverse effects on the piping system, the conveyed fluid or both. KiTEC is widely used for the transmission and distribution of potable water providing a second line of defense for the plumbing system.

UV Resistance and opacity

KiTEC pipes do not have ant effect of UV radiation when laid exposed. There is no light transmission.

Salient Features - Thermal Properties

Thermal Strength
KiTEC Composite Pipes are having pressure rating of 13.8 Kg/Cm2 at 23oC. and 11.0 Kg/Cm2 at 60oC. KiTEC Composite Pipe can safely be used for 6 Kg/Cm2 pressure at 80oC working temperature. Short term excursions to 95oC will not affect the overall performance. Design life span for KiTEC Composite Pipe is in excess of 50 years. KiTEC Plumbing Pipes are having pressure rating of 12.0 Kg/Cm2 at 23oC. and 6.0 Kg/Cm2 at 65oC. KiTEC Plumbing Pipe can safely be used for 4 Kg/Cm2 pressure at 80oC working temperature.

Thermal Expansion
KiTEC has a low coefficient of linear expansion, similar to copper tubing, and is far superior to alternate plastic pipe. This eliminates the need of installation "offsets" and the concern about abrading pipe due to constant movement as a result of temperature changes. Straight runs are always attainable with KiTEC pipe. Coefficient of Thermal Expansion for KiTEC Pipe is : 25 x 10-6 / oK. Low expansion coefficient is due to tie layer which eliminates the differential expansion of plastic and metal.

Resistance to freezing
In plumbing and water supply applications, KiTEC can withstand multiple multiple cycles of freezing and thawing while under pressure without bursting up to -40O C. temperature. Thawing can be done using a hot air blowgun, hot water injection, and electric blanket or heating cable method. An open flame, torch, or electric current should not be used to thaw the pipe.

Thermal Insulation
KiTEC is having Thermal Conductivity of 0.43 Watt/[m ok.]. KiTEC composite pipes provide an increased resistance to the onset of condensation or pipe sweating in a plumbing application. In case of hot water piping the insulation requirement is only 50% of the same required for conventional metal pipes.

Salient Features - Flow Properties

Higher flow
Because of smooth inside surface KiTEC pipe is scale free and gives higher and consistent flow throughout the service life. Friction drop properties for KiTEC pipes are represented by following graph. In case of KiTEC fittings, the equivalent length for various fittings is as given in the following table.

KiTEC - Most versatile Pipe for Plumbing
Advantages for Homeowners
Corrosion Free:
KiTEC’s inner and outer layers consist of polyethylene (PE). KiTEC is having, perhaps, the best chemical and corrosion resistance of any plastic used in the manufacture of plumbing pipes. The polyolefin family of plastics - PE included - is renowned for it’s toughness, long service life and resistance to deterioration in the most extreme environments. On the other hand, when metal or copper pipes are exposed to aggressive soil and water conditions, they are susceptible to corrosion and pitting.

KiTEC’s inner and outer layer of plastic is unaffected by corrosive soil or aggressive water. That’s why you’ll see KiTEC being used to re-pipe homes where metal pipes have failed prematurely.

Clean and Safe:
KiTEC plumbing system is designed to provide you with the cleanest drinking water possible. KiTEC’s clean, non-corroding plastic interior is resistant to deterioration in aggressive water conditions. You needn’t worry about odour, colour or taste problems arising because of the plumbing pipes in your home.

And given KiTEC’s built in permeation barrier, you have built in peace of mind that your buried water pipes will not be permeated by ground source contaminants.

Quiet:
Today’s demanding homeowners insist on quieter, more efficient plumbing systems. Noise often associated with water hammer in the pipes behind the walls is a distant memory.

That’s because KiTEC offers the strength of metal pipes without all the noise. KiTEC’s unique composite construction reduces water hammer pressure and the plastic layers reduce the noise. With KiTEC plumbing systems you’ll have no more shaking or rattling of metal pipes. It all adds up to a quieter home<

Better Flow:
KiTEC’s smooth inner plastic wall permanently resists scaling and mineral build-up, keeping water flow constant year after year. Unlike metal pipes, you won’t see a reduction in flow area with KiTEC. That means homeowners can enjoy a constant water pressure throughout the house, throughout the years.

Advantages for Builders and Plumbing Agencies
Easy to Install and Less physical exertion:
No more sweating joints every few feet. KiTEC’s convenient, lightweight coils allow you to install a professional plumbing system quickly and efficiently. Installation crews are less fatigued and larger coils mean less wastage. Quick to join:

Need to make a bend? Go ahead. Need to snake pipe around an obstruction? There’s nothing stopping you. When the system calls for a fitting, you simply cut, bevel the pipe, connect with the end of the fitting and tighten the nut for secure, long-term connections. It’s really that fast and simple. You need just 25% of the time as compared to conventional GI pipes for completing the jointing and installation.

Go anywhere with KiTEC:
KiTEC can be installed in walls and ceilings or surface mounted. It can be supported horizontally or vertically on 8 foot centers because its stiffness and expansion rate is similar to copper’s. KiTEC can be encased in concrete or buried underground without additional protection because its tough outer plastic layer resists chemicals and corrosive activity. KiTEC’s aluminum core provides a 100% permeation barrier against ground source contaminants like fertilizer and pesticide.

Fewer Fittings:
KiTEC uses fewer fittings – almost one fourth the fittings used in conventional system. Fewer fitting joints means less chance of leakage and less liability.

It’s not only designed for better long term flow rates, the inner plastic layer is noncorroding and won’t pit, pinhole, or erode in aggressive water conditions. KiTEC is designed to provide years of trouble free performance in the toughest of conditions. other pipes just don’t compare.

Widely Used:
Today, 8 of the top 11 homebuilders in the United States are using KiTEC on new housing developments. KiTEC is also being used to plumb thousands of residential, mid-rise and hi-rise buildings throughout Canada. In India, many of the reputed builders are proudly the use of KiTEC in their projects to the customers. Once you see it in action you’ll know why. You can bend it by hand and it keeps it shape. And there’s no need for pastes, solder, torches, solvent cements or special expansion tools. With KiTEC, you’ll reduce installation hassles on every project.

Readily Available:
KiTEC is warehoused and distributed from many locations across India through an efficient distribution network.

KiTEC Pex Pipe

KiTEC PE-AL-PEX pipe is in continuation of its philosophy of giving technologically superior products to the customer. KiTEC PE-AL-PEX multilayer barrier pipe and compression DZR Brass fittings are specially designed for the hot water / heating applications. 

KiTEC PE-AL-PEX multilayer barrier pipe is manufactured from high density cross-linked polyethylene as inner wall with an aluminium strip layer as the middle wall of the pipe which in turn is covered with a thin layer of UV Stabilized black polyethylene

Cross-linked polyethylene, commonly abbreviated PEX or XLPE, is a form of polyethylene with cross-links. PEX is made from high density polyethylene (HDPE). PEX contains cross-linked bonds in the polymer structure, changing the thermoplastic to a thermoset. Crosslinking is accomplished during or after the extrusion of the tubing. The required degree of cross-linking, according to ASTM Standard F 876-93, is between 65 and 89%. A higher degree of cross-linking could result in brittleness and stress cracking of the material. 

Cross-linking of polyethylene into PEX for pipes results in improved properties such as elevated temperature strength and performance, chemical resistance, and resistance to slow crack growth. 

The high-temperature properties of the polymer are improved. Adequate strength to 120-150°C is maintained by reducing the tendency to flow.

  • Chemical resistance is enhanced by resisting dissolution.
  • Low temperature properties are improved.
  • Impact and tensile strength are enhanced.
  • Scratch resistance property is enhanced.
  • Resistance to brittle fracture is enhanced.

PEX tubing cannot be used in applications exposed to sunlight, as it degrades fairly rapidly. KiTEC has, therefore, preferred to use PEX to take advantages of its above mentioned superior properties for internal layer and use PE with carbon black for external layer. To ensure safe use exposed to sunlight. 

Long life:

KiTEC PE-AL-PEX pipes are designed for 50 years projected life subject to the following pressure and temperature ratings
