IPE-RTIPipeIntroduction

PE-RTIPipeandFittingaremanufacturedinaccordancewith GB/T28799，usingethylene-octylenecopolymer asmain raw material, intended for high temperature resistance usage. Therawmaterialhas specialmolecularstructure，which includeslinearpolyethyleneasthebackbonechainplus controllablebranches,sothatthePE-RTIpipe and fittingshave excellentpressureresistance.Meanwhile，ithassuperior flexibility,then it canbeeasilybent without changing the shape. Italsoperformswellinlowtemperature.Plus theadvantages 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-RTI(oxygen resistance) floor heating pipe adopts three layers co-extrusion technique. The pipeiscoatedwithalayerofhotmeltglueandalayerofEvOH (oxygen resistance) evenly on the surface. The coatings can stoptheoxygenpenetrateintoheheatrecyclesystem effectively，andreduce thecorrosiononthe equipments.The picturebelowis thestructureofLiansuPE-RT丨(oxygen resistance)floor heating pipe,and the oxygen permeation flux of ourproduct satisfies therequirements ofplasticheatingpipe's oxygenresistanceinGB/T28799.

Introduction

The water supply function of PE-RT pipe is good, it can compare withPP-Rpipe.It can low down the cost and owns stronger competitiveness byreducing the usage of the fittings due to the excellent flexibility of thePE-RT pipe.Along with the applicationof thePE-RTpipe and thedevelopment of it'sraw materials'technique，PE-RTpipe has beendevelopedfrom typeIto type Il. Liansu's PE-RT Il water pipe and fittings are madefromtypellmaterialof hightechnique.It's long-term compressionresistance is better than traditionalPE-RTpipe which is made from type I material.

Application

Domestic cold and hot water supply.

Features

1.Light weight,easy to transport,installation and construction.
2.Excellent flexibility.Reducing the costby using lessfittings due to it's excellent flexibility.
3.The pressure on the bend will be loosed very fast, won't springback,easyto operate.
4.Little abrasion resistance of the inner pipe.The flow capacity is 30% greaterthanthemetalpipewiththesamediameter.
5.Lowcracktemperature.ThePE-RTpipehasexcellentlow temperatureresistance.Noneedstopreheatthepipebefore bend,andcancontinuetheconstructioninwinter.
6.No toxic auxiliaries in theproduction of the pipe.Smooth inner wall,wouldnotbecoveredwithdirtorcontaminated by bacterium,can be used in the portable water supply and other areassafely.
7.Using solvent weld joint or mechanical joint, reliable and no leakage.
8.Eco-friendly,can be recycled.
