Reasons for the misalignment of spiral steel pipes
In production practice, steel pipes are often degraded due to wrong edges and excessive tolerances. Therefore, it is necessary to analyze the causes of the misalignment of spiral steel pipes and their preventive measures. The sickle bend of the steel strip is the main factor causing the misaligne...Read more -
Inspection standards and welding control issues for thick-walled steel pipes
Through observation, it is not difficult to find that whenever thick-walled steel pipes, thermally expanded pipes, etc. are produced, strip steel is used as the production raw material, and the pipes obtained by thick-walled welding on high-frequency welding equipment are called thick-walled stee...Read more -
Seamless steel pipe heat treatment process
Annealing is to heat the cold-rolled precision bright steel pipe to an appropriate temperature, adopt different holding times according to the material and workpiece size, and then slowly cool it. The purpose is to make the internal structure of the metal reach or approach an equilibrium state an...Read more
