Production process application
Welded square pipes are used in construction, machinery manufacturing, steel construction projects, shipbuilding, solar power support, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, Housing construction, etc.
The narrow billet of the welded square tube can produce welded pipes with larger pipe diameters, and the billet of the same width can also be used to produce welded pipes with different pipe diameters. But compared with the straight seam square pipe of the same length, the length of the weld is increased by 30-100%, and the production speed is lower.
Large diameter or thick welded square pipes are generally made directly from steel blanks, while small welded pipes and thin-wall welded pipes only need to be directly welded through steel strips. Then after a simple polishing, drawing is fine. Therefore, most of the smaller diameter welded pipes use straight seam welding, and the large diameter welded pipes mostly use spiral welding.
