Stainless steel seamless pipe is a high-quality steel pipe product. It is made by perforation, cold drawing or hot extrusion. It has no welding marks, smooth and uniform inner and outer walls, excellent corrosion resistance, high strength and long service life.

The manufacturing of stainless steel seamless pipe mainly includes the following steps:

Raw material preparation: Select high-quality stainless steel billets, shear and heat according to the required specifications.

Piercing: Use a head perforator to perforate the billet at high temperature to form a thick pipe.

Extension and diameter reduction: Adjust the size of the steel pipe and refine the structure through cold drawing or hot extrusion.

Annealing: Heat treatment to eliminate internal stress and improve mechanical properties.

Straightening and sizing: Adjust the straightness and cut to the required length.

Detection: Conduct comprehensive quality inspection, including size, mechanical properties, surface defects and other items.

Stainless steel seamless pipes are widely used in many fields such as chemical industry, petroleum, natural gas, pharmaceuticals, food processing, medical equipment, aerospace, etc., especially in applications that require high-quality and high-purity fluid transmission or load-bearing structures.
