LESSO Floor Heating Pipes

PE-RT II pipe special for Solar is made of PE-RT II resin appended with special UVA, which has excellent pressure-resistance and hot&low temperature-resistance, Weather-resistance as well. Product fulfills the requirement of industrial standard CJ/T 318-2009.

◎ The central heating system is constituted by the all pipelines which take heat from heating resource to customers.
◎ The structure of heating-preservation pipe for central heating system: General divided into 3 parts:
◎ Internal layer is pressured plastics pipe: PE-RT II pipe
◎ Middle layer is foamed heating-preservation layer: PU foam. The heat conductivity coefficient λ50= 0.032 W/m·K;
◎ Outside layer is HDPE single-wall corrugated pipe or HDPE surface layer. conductivity coefficient λ= 0.42 W/m·K

PE-RT Pipe and Fitting are manufactured in accordance with CJ/T 175-2002, using ethylene-octylene copolymer as main raw material, intended for high temperature resistance usage. The raw material has special molecular structure, which includes linear polyethylene as the backbone chain plus controllable branches, so that the PE-RT pipe and fittings have excellent pressure resistance. Meanwhile, it has superior flexibility, then it can be easily bent without changing the shape. It also performs well in low temperature. Plus the advantages of sanitary, heat welding joints, reliable connection without the worry of leakage, it is an ideal plumbing system for floor heating.
