Release time:2018-10-22 13:35

Urban drainage system engineering facilities are important urban infrastructure, is the collection, transportation, treatment, discharge of urban sewage, industrial wastewater and rainwater systems engineering. The basic task of drainage engineering is to protect the environment from pollution, to promote the development of industrial and agricultural production and to ensure the health and normal life of the people. As a part of the urban water circulation system, urban drainage works can play a role in regulating the amount of water in the canal. The inner ribbed reinforced bellows produced by the inner ribbed pipe equipment can avoid the retention and accumulation of sewage and rainwater in the city.
The service life of HDPE inner rib reinforced bellows is longer than 50 years, which has been proved not only by international standards and new international standards, but also by advanced countries. The service life of cement management theory is 20 years, but it is silicate. It has been corroded by acid and alkali for a long time, and its service life is greatly reduced. All over the country, cement pipes have to be replaced in a few years because of the ground subsidence caused by sewage leakage, joint fracture.
HDPE inner rib reinforced corrugated pipe is a kind of environmental protection pipe, it can resist corrosion, and lighter quality, installation is very simple, but when laying the pipe, what are the matters needing attention?

1. In general application, Shenzhen manatee HDPE inner rib reinforced bellows can be hidden in pipe grooves, pipe wells, pipe trenches and ceiling. When laying pipe wells, we should set up a maintenance door at each layer of the pipe wells to facilitate our later maintenance work. Similarly, when the pipe is hidden in the roof or pipe grooves, it also needs to be retained. There is a maintenance door. For indoor piping installation, it is necessary to note that there is enough space to install and replace accessories during installation.
2. HDPE inner rib reinforced bellows should not affect production operation, transportation and building use. Avoid passing on the production equipment as far as possible, and do not arrange on the equipment which can cause burning, explosion or damage to raw materials.
