We are renowned Manufacturer and Supplier of a wide range of PE-AL--PEX Pipes. Made from high-density cross-linked polyethylene and aluminium strip layers, our entire range is reliable and used extensively by the construction industry. Buyers can purchase PE-AL--PEX Pipes form us in bulk and expect on time delivery. We offer them in varied specifications and offer customized PE-AL--PEX Pipes as well.

 

Details :

  • Specially designed for the hot water / heating applications
  • High density cross-linked polyethylene as inner wall
  • An aluminium strip layer as the middle wall
  • Pipe is covered with a thin layer of UV Stabilized black polyethylene.

 

KiTEC is a well known brand in the construction industry for its quality and integrity. 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 applicationsw. KiTEC PE-AL-PEX multiayer 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 Stabilised black polyethylene.

 

What is PEX?

PEX is the short form for Cross-linked Polyethylene. Cross-lined Polyethylene is a polyethylene material which has undergone a change in molecular structure using a chemical or a physical process whereby the polymer chains are chemically linked and is commonly abbrevated as PEX or XLPE. Corss-linked bonds in the polymer structure, changes the thermoplastic to a thermoset.

 

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.

 

Improved Properties

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 creack gorwith.

 

The high-temperature properties of the polymer are improved. Adequate strength to 120-150oC 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.l

  • Scratch resistance property is enhanced.

  • Resistance to brittle fracture is enhanced.

 

PEX tubing cannot be used in applicatiosn 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.

 

Identification : Inner Layer in Orange color and outer layer in UV stabilised black color with continuous co-extrucded red line.

 

KiTEC Recommends use of DZR Brass fitting with PE-AL-PEX pipes for recommended applications. Full Plastic fittings can be used in case the pipes are being used for chemical transportation. Please contact the company for with full details like chemical name, concentration, temperature as well as pressure for suitable recommendations in case the pipes are being used in chemical or gaseous fluids.

@ 180 oF (82oC)

Typically unchanged

Typically Increases

Pex is suitable for both low - and elevated - temperature applications

Elongation at Break

Unchanged or Increases

Improved flexibility to withstand installation stresses while resisting tensile deformation

Environmental Stress Crack Resistance

Increases

Greater resistance to environmental hazards. Improved toughness and abrasion resistance.

Resistance to slow crack Growth

Increases

Greater resistance to environmental hazards Such as scratches. Improved toughness and abrasion resistance.

Creep Resistance

Increases

Improved stability over long-term pressurization and loads. The Traditional HDPE stress curve "Knee-Point" is typically eliminated.
