Anti-corrosion method for inner and outer wall of water supply steel pipe

The current implementation of the Yellow River water source Taiyuan urban water supply project is to lay a water supply network within the city. The pipe diameter of the pipeline is DN300mm-DN2220mm, and the total length is 163km. The large-diameter pipelines are all made of steel pipes. In order to ensure the quality of the project, the life of the steel pipe is prolonged. The corrosion protection of the inner and outer walls of the steel pipe is extremely important. There are many factors in the corrosion of underground pipelines, such as the soil pH value in the pipeline area, and the grass roots will penetrate the general coating. The inner wall of the water supply pipe is made of cement mortar, and the outer wall is made of epoxy coal tar pitch paint. After years of engineering practice, it proves to be a kind of non-corrosion.

3PE anti-corrosion steel pipe anti-corrosion layer thickness standard

SY/T 0413-2002 Technical Standard for Polyethylene Anti-corrosion Layer of Buried Steel Pipeline Oil and Gas Industry Standard (SY) SY/T0413-2002 To ensure the quality of extruded polyethylene pipe anti-corrosion layer, prolong service life and improve Economic efficiency, this standard is specially formulated. This standard is applicable to the design, production and construction acceptance of extruded polyethylene pipe anti-corrosion coating. The extruded polyethylene anti-corrosion layer can be divided into a normal temperature type (N) with a long-term working temperature not exceeding 50 ° C and a high temperature type (H) with a long-term working temperature not exceeding 701 C. Buried steel pipe extrusion polyethylene

Common anti-corrosion steel pipe anti-corrosion technology Daquan

Anti-corrosion steel pipe refers to a steel pipe that has been treated by anti-corrosion technology and can effectively prevent or slow down the corrosion phenomenon caused by chemical or electrochemical reaction during transportation and use. However, we do not fully understand the anti-corrosion methods and processes of various anti-corrosion steel pipes. For 2PE/3PE anti-corrosion, 2PP/3PP anti-corrosion, fire-proof pipeline buried anti-corrosion, steel-plastic composite pipe anti-corrosion, underground pipeline reinforcement grade anti-corrosion, epoxy coal anti-corrosion Introduction of several major anti-corrosion products such as steel pipe anti-corrosion and pe anti-corrosion steel pipe anti-corrosion.
