Double-wall corrugated pipe
Double-wall corrugated pipe was successfully developed in Western developed countries in the early 1990s and has been widely used. With the rapid development of urbanization in our country and the country's further emphasis on environmental protection, double-wall corrugated pipes will have great application space. Its reasonable hollow ring structure design has the characteristics of light weight, high strength and good toughness. At the same time, it also has the advantages of easy laying, low resistance, low cost, strong corrosion resistance, etc. Its performance and economic benefits far exceed the traditional Iron pipes and cement pipes are updated products of engineering pipes and are widely used in various pipelines buried underground.

Product Features
Large ring stiffness
Ring stiffness refers to the relationship between pipe deformation in the vertical direction and the corresponding load. The products produced by our company have two levels of ring stiffness: / and /, which are suitable for indoor and outdoor buried use. (It is recommended that when the soil foundation is complex and the external load is large, / grade products should be given priority). The pipe wall adopts a reasonable hollow ring structure design, which greatly improves the ring stiffness of the pipe and can withstand greater environmental pressure with the same materials.
, small fluid resistance
The inner wall is smooth, and the friction resistance is obviously smaller than that of concrete pipes. Practice has proved that under the same slope, the same flow rate can be achieved by using double-walled corrugated pipes with smaller diameters. Under the same pipe diameter, the use of double-walled corrugated pipes can reduce the slope and effectively reduce the amount of excavation work.
, Good connection sealing performance
Using elastic sealing ring socket connection, the connection sealing performance is obviously better than that of metal pipes and concrete pipes.
, Excellent corrosion resistance
It has excellent corrosion resistance from acid, alkali, salt and other media, and its corrosion resistance is obviously better than that of metal pipes and concrete pipes.
, Simple construction
Light weight, large length (fewer joints, low requirements for pipe trenches and foundations, easy connection, fast construction, low overall price.
, long service life
The pipe has strong wear resistance and long service life.
Scope of use
, municipal engineering, construction underground drainage, sewage pipes
, underground post and telecommunications optical fiber, cable sheathing pipe
, Buried casings for roads, railways and other roads
, farmland water conservancy and irrigation pipelines
, transportation of chemical and mining fluids.
