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.
Generally, the oxygen resistance of plastic pipe is poor, so, the plumbing system need to be used with the pipes bear oxygen resistance if it requires. Liansu PE-RT (oxygen resistance) floor
heating pipe adopts three layers co-extrusion technique. The pipe is coated with a layer of hot melt glue and a layer of EVOH (oxygen resistance) evenly on the surface. The coatings can
stop the oxygen penetrate into he heat recycle system effectively, and reduce the corrosion on the equipments. The picture below is the structure of Liansu PE-RT (oxygen resistance) floor heating pipe, and the oxygen permeation flux of our product satisfies the requirements of plastic heating pipe.
