    PE-X

    PE-X pipes are made of HDPE and crosslinking accessaries. According to the difference of techniques, it has four types, PE-Xa, PE-Xb, PE-Xc, PE-Xd. Our company provides PE-Xa,PE-Xb. These pipes have excellent heat-resisitance and mechanical physic performance. They are regarded as new generation green pipes, the most widely used pipes in floor radiant heating system.

    Features:

    1. Broad temperature scope, long usage life up to 50 years.                                                         

    2. Hardness and elasticity, higher inner pressure strength.                         

    3. Higher chemical corrosion resistance and environmental stress cracking i.e. more kinds of chemical liquid can be conveyed.                                          

    4. With low surface tension, it can effectively prevent scale.                        

    5. In conformity with potable water hygienic standard, the pipe contains non-toxic components, not being rotten and breeding bacteria                               

    6. Having smoothness both inner and outer walls, the pipe have featured its smallest flow resistance and low noise.                                              

    7. Good bending property, easy to adjust while installation.                       

    8. Light weight, convenient for installation and transportation. 

    Applications:

    1. Cold and hot water system for buildings                                

    2.air-condition system and sewage treatment system.                             

    3. Concentration heating system in the residential houses                          

    4. Floor radiant heating system and snow melting system of airport and traffic network.
