The HDPE double-wall corrugated pipe is the best drainage pipe, has been widely used in our country, so the traditional cement drainage pipe is gradually replaced by hdpe double-wall corrugated pipe.
HDPE double-wall corrugated pipe used for drainage is a modern type of pipe used for outdoor drainage of buildings and municipal sewage by extrusion forming with polyethylene resin as the main raw material and adding proper amount of additives. It has the advantages of light weight, modest drainage resistance, great compressive strength, corrosion resistance, convenient construction, etc., is the ideal material to replace cast iron pipe and cement pipe.
The use of hdpe double-wall corrugated pipe marks the progress of our country in the field of drainage engineering, because it has a lot of advantages compared with the traditional cement pipe. Take a look at the specific advantages of China HDPE parts factory.
Advantages of HDPE double wall corrugated pipe over cement pipe
HDPE double-wall bellows show higher economic and social benefits than cement tubes.
01 HDPE double-wall below have low permeability
hdpe double-walled below have a permeability of 0.005. The cement pipe is 0.018. This advantage is that when sewage is discharged, it will not cause pollution to the underground environment. Moreover, when the cement pipeline is installed, the connection is easy to cause the problem of insecurity, and the problem of penetration will be more serious.
02 HDPE double-wall corrugated pipe construction difficulty is modest, short construction period
Because the weight of HDPE double-wall corrugated pipe is considerably lighter than the cement pipe, it is extremely easy to plug and socket, so the construction difficulty is considerably reduced; and the shortest HDPE double-wall corrugated pipe is 6 meters a root, and the cement pipe is 2.5 meters a root, considerably shortening the construction period.
03 HDPE double-wall below have tiny requirements for the trench bottom
Because the cement pipe is a steel pipe, in order to ensure the socket effect, the bottom of the ditch must be treated flat, the best foundation layer, and the construction personnel are required to have absolute responsibility. HDPE double-wall corrugated pipe is a flexible pipe, and it does not require a high gully bottom.
04 HDPE double-wall corrugated pipe will not crack under extreme pressure.
By contrast, HDPE double-wall corrugated pipe is a plastic pipe with a excellent elongation, 20 times that of steel pipe and 6.5 times that of PVC pipe, which means that when the ground subsidence or earthquake occurs, HDPE double-wall corrugated pipe will not be deformed and cause rupture, which is not available in the traditional cement drainage pipe.
05 HDPE tube is more environmentally friendly.
The cement pipe is inelastic, although equipped with rubber ring, but the sealing effect is poor, especially because the cement pipe is heavy and difficult to construct. The construction personnel merely ignore the effect of socket, resulting in the rubber ring loss, so that the permeability of the pipe increases.
06 HDPE inner surface smooth, no scaling
cement pipe is easy to scale, after scaling, the pipe diameter is reduced, affecting the flow rate.
07 HDPE tube has a long service life.
The traditional cement drainage pipe has been verified by us and can no longer be used after 20 years. The hdpe double-wall corrugated pipe has been verified that it can be used for more than 50 years, and can even reach a service life of 70 years, so the economic benefits of the traditional cement drainage pipe can not be compared with the hdpe double-wall corrugated pipe.
08 HDPE tube is easy to transport and install, no loss
Cement pipe is heavy, not easy to transport and install, and easy to lose during transport and installation.
