Use solvents and emulsions to clean the surface of the anti-corrosion spiral steel tube, which can remove the organic matter on the surface of the spiral steel tu...Read more -
Surface defects of seamless steel pipe and their causes
The causes of surface defects of seamless steel pipes are intricate. There are hundreds of influencing factors listed, and sometimes there are dozens of factors for the same defect, and the occurrence of defects has a great relationship with the steel type. This is why the production of seamless ...Read more -
Troubleshooting and Production Technology of Straight Seam Steel Pipe
Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. It is usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe, and so on. The production process of straight seam we...Read more -
Position regulation and purity improvement of straight seam steel pipes induction coil
Adjustment of the position of the high frequency induction coil of the straight seam steel pipe: The excitation frequency of straight seam steel pipe is inversely proportional to the square root of capacitance and inductance in the excitation circuit, or proportional to the square root of voltage...Read more -
Inspection standards and welding control problems of thick-walled steel pipe
Through observation, it is not difficult to find that in the production of thick-walled steel pipes, thermal expansion pipes, etc., the pipes obtained by thick-walled welding on high-frequency welding equipment are called thick-walled steel pipes. Among them, according to the different uses and d...Read more
