The spiral steel pipe used in the sewage pipe network is actually a sewage pipe. Because the multiple pipes are intricate and different in size, they form a denser network, so it is also called a pipe network. Due to the corrosive nature of sewage, the spiral steel pipe used in the sewage pipe network generally needs to be treated with internal and external anti-corrosion treatment, and the specific method will be formulated according to the design requirements.
Spiral steel pipe for sewage pipe network is a spiral welded steel pipe made of strip steel or coiled plate through a series of cold processing. It has multiple advantages such as high production efficiency, easy welding, various specifications, and low price. widely used. It is only one branch of sewage pipe network, it can also be used in water supply and drainage projects, structural pillars, municipal engineering, piling engineering, oil and gas transmission, thermal pipelines and other projects.
The anti-corrosion of the spiral steel pipe for the sewage pipe network depends on the acidity and alkalinity of the sewage. Generally, the domestic sewage will be treated according to the commonly used anti-corrosion method, that is, the anti-corrosion of the internal and external epoxy coal tar pitch, while the industrial sewage needs a stricter method, because Industrial sewage generally has a relatively high pH, and general coatings cannot be used in this environment. Commonly used anti-corrosion methods for industrial sewage include polyurea anti-corrosion, polyethylene anti-corrosion, and tetrafluoro-lined anti-corrosion methods. Generally speaking, a relatively complete treatment plan has been issued for sewage pipelines, and Wanquan can be applied to various environments.
