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.
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
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
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.
