Welding treatment of thick-walled spiral steel pipe
Thick-walled spiral steel pipe is a method of arc welding under the flux layer, which is formed by using the heat generated by the arc burning between the flux and the welding wire under the flux layer, the base metal, and the molten wire flux. During use, the principal stress direction of the th...Read more -
Spiral steel pipe for anti-corrosion purposes
Due to the corrosion of steel pipes and equipment, production enterprises have stopped production, and production quality has declined. Affect domestic gas supply, heating steam or hot water, and bring many difficulties to people’s life. Leakage of buried oil, gas, water, and other pipeline...Read more -
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 -
Practical advantages and diameter expansion technology of straight seam steel pipe
In a sense, straight seam steel pipe is a welding process of steel pipe that is opposite to spiral steel pipe. The welding of straight seam steel pipes is relatively common in the market because the process is relatively simple, the cost of welding is relatively low, and high efficiency can be ac...Read more -
Analysis of Process Elements Affecting High-Frequency Longitudinal Welded Pipe
The main process parameters of high-frequency straight seam welded pipe include welding heat input, welding pressure, welding speed, opening angle, position and size of the induction coil, position of impedance, etc. These parameters have a greater impact on improving the quality of high-frequenc...Read more
