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 -
Large-diameter welded steel pipe production process
1: Conduct physical and chemical inspections of raw materials such as strip steel coils, welding wires, and fluxes. 2: The head-to-tail butt joint of the strip steel adopts single-wire or double-wire submerged arc welding, and automatic submerged arc welding is used for repair welding after being...Read more -
The difference between thin-walled spiral steel pipe and thick-walled spiral steel pipe
The concept of thin-walled spiral steel pipe: the strip steel is fed into the welded pipe unit, rolled up by multiple rollers, and the strip steel is gradually rolled up to form a circular tube billet with an opening gap. Adjust the reduction of the extrusion roller to make the weld seam gap Cont...Read more
