Seamless tubing is an important industrial material widely used in fields such as petroleum, chemical, power, aviation, etc. The production process and technology are very complex and refined, requiring multiple steps to produce high-quality products.
The production process of seamless tubings includes raw material preparation, hot rolling, cold drawing, acid washing, annealing, cutting and other links. Preparing raw materials is the first step in the entire production process, requiring the selection of high-quality steel for processing, such as stainless steel material SS316, SS316L. Hot rolling is the process of heating raw materials to a certain temperature and then continuously rolling them on a rolling mill to form a fixed pipe wall and diameter. Cold drawing is the process of cold working and shaping hot-rolled pipes to increase their tensile strength and hardness. Acid washing is the process of pickling cold drawn pipes to remove surface oxides and contaminants, thereby improving their surface quality. Annealing is the process of heating acid washed pipes to eliminate residual stresses and improve their structure and properties. Finally, cut the seamless tubing into the required length.
