PE-AL-PE COMPOSITE PIPE

XINFENG brand PE-AL-PE Composite Pipe is a new penetration of pipe engineering and a great reformation of pipe manufacture. It has many sharp chemical and physical properties, with which it enjoys advantages of both metal pipe and plastic pipe, thus has been widely used in cold and hot water, gas, compressed air, solar energy and air-conditioned, heating, medical, foodstuff and chemical fluid supply pipe systems, of both industrial and household. It's the best substitute for all-plastic pipe, copper pipe and Galvanized pipe.

With complying with ASTM standards of USA in its manufacture and productions, tested by national authorities, XINFENG pipe's quality meets completely that of USA and European Similar products.

QUALITY STANDARDS

ISO9002 Quality System Certified
ASTM F1281/F1282 Standards of USA

Structure
XINFENG pipe's inner and outside layers are of special PE, Hygienic, toxic-free and smooth, Its middle layer of AL is able to refuse 100% of gas permeability, give it both advantages of metal and plastic pipe, but eliminate their own disadvantages.

Mechanical Parameter
Thermal Conductivity: 0.45 W/m.K
Thermal Expansibility: 2.5*10-5 m/m.K
Bending Radius: >=5D (D=Outer Diameter)
Working Temperature: -40°C ~+95°C 
Working Pressure: 1.0 MPa

Cool & Hot Water Pipe System
Its smooth inside appearance, rust-free and scale–free leading to a more 30% flow of XINFENG pipe than metal pipe. East bending, installed directly on girder, buried inside wall and cement concrete, XINFENG pipe can be found with a simple metal detector, it's very suitable for cold and hot water system of both household and industry.

Housing Gas Pipe System
The continually-welded middle layer of AL-Pipe makes XINFENG pipe able to stand Hi-working Pressure and no gas(oxygen) permeability, it's long enough to decrease fitting attached, thus no leakage. XINFENG pipe, used in compressed air, gas, oxygen etc. supply line is assured safe.

Underfloor Heading System
Hard but able to bend. not accessible to deform because of pressure, even deformed, not split never spring back and long enough, it decreased fitting applying to avoid flow resistance and leakage, it enjoys a wide range of working temperature (-40°C ~ +95°C). Underfloor heating is a hygiene and Hi-class heating system, which has been widely used in world.
Few pipe meets the technical requirements of underfloor heating system, but XINFENG pipe can do it!

Solar Energy & Air-conditioning Matching Pipe System
Not accessible to frost and Hi-thermal preservation can save the cost of thermal-preservation, thus give these systems hi-efficiency working.

Medical, Foodstuff & Chemical Industry Pipe System
XINFENG pipe's inside and outside PE doesn't react chemically, and it's no leakage, hygiene and safe. As medical and oxygen supply pipe, it can be assured safe and the purity of its carrying media. As foodstuff industrial fluid supply pipe, it's corrosion-resistant. contamination-resistant to assure foodstuff not to be contaminated during manufacture. Below 60°C, PE is able to stand all kind of (in density) acid and alkali solutions, static-tree, thus it can be just used in chemical industry but needless to extra protection.
