HDPE Double wall Corrugated Pipe

Jiashang Pipeline Industry
Product introduction
Product specification

    The raw material of double-wall corrugated drain pipe is high density polyethylene. Its inner wall is 

smooth and its appearance is unique circular corrugated. It is a new type of light pipe material. It has

 the advantages of light weight, external pressure resistance, aging resistance, good sanitary perfo-

mance, fast construction and long service life. It can save a lot of money and construction time for 

users in the field of non-pressure drainage, sewage discharge and communication cable engineering.

 It is traditional drainage. Ideal substitute for sewage pipe. This product is widely used in large-scale 

water conveyance, water supply, drainage, sewage, exhaust, subway ventilation, mine ventilation, 

farmland irrigation, etc. This product is mainly used in the field of pressure-free drainage, sewage and

 communication cable engineering.

Product performance:

    1. Chemical resistance: resistance to acid, alkali, salt and other chemical media erosion, not corrod-

ed by rotten substances in the soil.

    2.Impact resistance: The pipe has unique ring ripple impact resistance, pressure resistance, and is 

not easy to rupture due to foundation subsidence. It has strong resilience after deformation and ada-

ptability to special foundation.

    3.Aging resistance: Pipes are usually black and can withstand direct sunshine during storage and 

construction.

    4.Cold resistance: Pipes will not be frozen cracked or expanded and leaked at -80℃.

    5.Light weight: light weight, easy to transport, easy to construct, buried pipe only need excavator, 

not large equipment.

    6.Convenient connection: Seal ring socket connection, reliable combination, fast installation, in the

 construction of urban drainage projects, can reduce the required engineering time and engineering 

costs.

    7. Abrasion resistance is superior: it is better than steel pipe and cement pipe in abrasion resistance

, and the transportation ability of domestic water and waste residue is stronger.

    8.Excellent drainage circulation: smooth inner wall, small friction resistance, strong transportation 

capacity for oil pollution and waste residue, rapid and smooth discharge.

    9.Economy: Compared with reinforced concrete pipe, cast iron pipe and FRP pipe, the cost of const-

ruction, management and maintenance is lower.

    10.Environmental impact: The sealing performance of the pipe wall is good, and it has a strong pro-

tective effect on groundwater resources; HDPE is a non-toxic raw material, harmless to the land, and 

can be completely recycled.
