The problem of uneven thickness of the anti-corrosion coating of the spiral steel pipe and the treatment method
Spiral steel pipes are mainly used as fluid pipes and piling pipes. After the steel pipes are made, if they are used for running water, they will generally be treated with anti-corrosion on the inner or outer surface. The general anti-corrosion includes 3pe anti-corrosion, epoxy coal tar anti-cor...Read more -
Several tips to prevent pipeline corrosion
Pipe corrosion occurs because metals are sometimes susceptible to chemical reactions that weaken them. Once the metal is weakened, it is prone to rust and can form cracks and holes, which is a big problem. Therefore, pipeline corrosion protection is critical, especially because once corrosion beg...Read more -
Introduction of the production process of steam direct buried pipeline
Due to its good thermal insulation performance, the steam direct buried pipeline is used more and more, so the steam direct buried pipeline is widely used in urban construction projects, but many people do not know this new type of thermal insulation pipeline product. Let me introduce to you the ...Read more -
The characteristics of fire protection plastic-coated steel pipe, the difference between galvanized steel pipe and plastic-coated steel pipe
First, the characteristics of fire protection plastic-coated steel pipe: 1. Hygienic, non-toxic, no fouling, no growth of microorganisms, and ensure fluid quality. 2. Strong flame retardant ability. Under the combustion test, the coating has no spontaneous combustion and does not fall off. 3. The...Read more -
What is the difference between hot-dip galvanized steel pipe and hot-dip galvanized steel pipe SC
1. The representation method is different: Hot-dip galvanized steel pipe generally refers to the standard nominal diameter of the water pipe, which is represented by DN. Hot-dip galvanized steel pipe SC means that the wire is laid through the steel pipe (low-pressure fluid welded steel pipe) SC i...Read more -
The simple difference between ERW steel pipe and HFW steel pipe
Resistance welding, as the name implies, is a method in which pressure is applied through electrodes after the weldment is assembled, and the resistance heat generated by the current passing through the contact surface of the joint and the adjacent area is used for welding. High-frequency welding...Read more
