HDPE double-wall corrugated pipe , also known as high-density polyethylene double-wall corrugated pipe , is a pipe with corrugated structure processed by  extrusion molding with DPE as the main raw material and necessary additives. It is a new type of lightweight pipe that is environmentally friendly, safe and cost-effective , and it is a new type of material with annular corrugated structure outer wall and smooth inner wall . At present , in the urban drainage system , plastic pipes have gradually replaced traditional pipes such as concrete pipes and cast iron pipes to become the mainstream pipes . Among the plastic pipes , HDPE double-wall corrugated pipes are the main ones , which are widely used in municipal drainage projects.

The full name of hexagonal pipe is high-density polyethylene ( HDPE-IW)hexagonal structure wall pipe , and the outer wall is an annular corrugated structure , which is a new type of sewage pipe . The ring stiffness exceeds 50 kN , and it is suitable for use environments from 60 ° to minus 60 ° C , and has excellent resistance to environmental stress cracking and crack propagation . The service life is up to 70 years , the bottom of the pipe is more compact , the  groove is in contact with the pipe surface , and the backfill has no dead ends.

A-type tube: HDPE hollow wall winding pipe type A is a structural wall pipe made mainly fro- m high-density polyethylene ( HDPE) through a special winding molding process. This type of pipeline has a unique " I-shaped" structure , with flat inner and outer walls and a structural wall in the middle, representing thecharacteristic characteristics of hollow wound pipes.

B-type tube: HDPE winding structure wall B-type pipe is a new type of irregular structurew-  all pipe made by high-density polyethylene hot winding forming process . It has the characteristics of long service life , high resistance to external pressure ,g-  ood connection , no leakage , environmental protection and no pollution. HDPE winding structure wall B-type pipe was initially introduced by domestic enterp- rises from the German Kra company, and is therefore commonly referred to as  Kra pipe in China .

PE-RT  II  prefabricated  directly  buried  insulation  pipe  -  high-density polyethylene outer protection pipe polyurethane foamed prefabricated directly buried thermal insulation composite plastic ( referred to as PE-RT II thermal insulation composite pipe plastic pipe) , which is closely combined with high- density polyethylene outer protection pipe , polyurethane foam insulation layer and working pipe . PE-RT II prefabricated directly buried insulation pipe has excellent performance and is used in the urban central heating secondary pipe network pipeline system , its outer protective layer, insulation layer, working pipe  three  parts ,  the  outer  protective  layer  material  is  high-density polyethylene; The insulation layer is made of rigid polyurethane foam; The PE- RT II working pipe is made of type II heat-resistant polyethylene ( PE-RT II) special pipe raw material , which is resistant to low and high temperatures up to -40 to 110 ° C.

MPP power pipe, the full name of modified polypropylene (Modified Polypropylene) power cable protection pipe, is a new type of power cable protection pipe. It uses modified polypropylene as the main raw material, processed by special technology, has a variety of excellent characteristics, does not need a large number of excavation excavators and damage the road surface, in the road, railway, buildings, riverbed and other special sections of the laying of pipelines and cables and other construction projects, widely used in municipal, telecommunications, electricity, gas, tap water, heat and other pipeline projects.

HDPE nano antibacterial self-cleaning pipe is a new type of thermoplastic pipe, which is based on the excellent performance advantages of HDPE pipe, adding nano antibacterial masterbatch to the inner layer of HDPE pipe, and co-extrusion is made of three-layer ABA or three-layer ABC new pipe with antibacterial, hygienic and self-cleaning effects.
