Causes of wrong edges of large-diameter spiral steel pipes (SSAW): In the production of large-diameter spiral steel pipes, misalignment occurs from time to time, and there are many influencing factors. In production practice, steel pipes are often degraded due to dry misalignment and out-of-tolerance. Therefore, it is necessary to analyze the causes of wrong edges of large-diameter spiral steel…
Read MoreSeamless steel pipes are much higher than welded pipes in terms of corrosion resistance and pressure and high temperature resistance. With the improvement of welded pipe manufacturing process, mechanical properties and mechanical properties are gradually approaching seamless pipes. The production process of seamless pipe is more complicated, and its price is more expensive than welded pipe. Based on the…
