br/Caliber corrugated pipes
The permeability of large-diameter corrugated pipes is much lower than that of cement pipes? Less than %? To groundwater Will not cause secondary pollution
The cement pipe is inelastic. Although it is equipped with an apron, the sealing effect is poor. Especially the construction workers, because the cement pipe is heavy and difficult to construct, simply ignores the socket effect, resulting in the loss of the apron. Function: thereby increasing the permeability of the pipe.
. The service life of large-diameter corrugated pipes is long, more than 10 years.
The safe service life of large-diameter corrugated pipes is more than 20 years. This has not only been proved by international standards and new international standards, but also has been proved by advanced countries. . Cement pipes theoretically have a service life of 10 years. However, as they are silicate pipes, they are corroded by acids and alkalis for a long time and their service life is greatly reduced. There are examples all over the country where cement pipes have to be replaced within a few years due to sewage leakage, causing the ground to sink and the joints to break.
. The inner surface of large-diameter corrugated pipes is smooth, does not carry positive and negative charges, and does not scale.
Cement pipes are easy to scale. After scaling, the pipe diameter will be reduced, which will affect the flow rate.
Large-diameter corrugated pipes are light in weight, easy to transport and install, and have no loss
Cement pipes are heavy in weight, inconvenient to transport and install, and are easily lost during transportation and installation
