What are the detection methods of oil casing
Oil casing is a high-end product produced by steel pipes. There are many types of casings, and there are many varieties and requirements for casing end buckle types. The machinable buckle types include STC, LC, BC, VAM, and other buckle types. The production and installation process of oil casing...Read more -
The principle of anti-corrosion steel pipe
The coating anti-corrosion steel pipe is a uniform and dense coating formed on the surface of rust-removing metal pipes, which can isolate it from various corrosive media. Steel pipe anti-corrosion coatings are increasingly using composite materials or composite structures. These materials and st...Read more -

Diameter expansion technology and detection method of straight seam steel pipe
Expanding technology of straight seam steel pipe: 1. Preliminary rounding stage: the fan-shaped blocks are opened until all the fan-shaped blocks touch the inner wall of the steel pipe. At this time, the radius of each point in the inner tube of the steel pipe within the step range is almost the ...Read more -
Advantages and installation precautions of steel-plastic composite steel pipe
In recent years, the status of ordinary steel pipes has declined rapidly. The fundamental factor is that environmental corrosion is serious. Even if the wall thickness of the steel pipe is large, it is always unrealistic to use the wall thickness to slow down the corrosion, because the wall layer...Read more -
