Annealing, a crucial step for stress relief and grain refinement, precedes pickling to remove surface impurities. Oiling provides temporary corrosion protection. Multiple cold-drawing stages refine dimensions and enhance strength. Further treatments include heat treatment for structural integrity, straightening for uniformity, hydraulic testing for quality assurance, marking for identification, and finally, storage for distribution.

• Production Process of Hot-Rolled Seamless Steel Pipe:

The process initiates with the preparation of tube billets, followed by heating to high temperatures to enable shaping. Perforation is achieved through various methods, including drilling. The subsequent steps involve three-roller or cross-rolling and continuous rolling to shape the billet into a seamless tube. De-piping ensures uniformity and removes surface imperfections. Sizing is performed to achieve the desired dimensions. Cooling follows to set the structure, with straightening ensuring uniformity. Hydraulic testing verifies the integrity of the pipe. Marking facilitates identification, with additional detection measures employed to ensure the integrity of the seamless steel pipe.
