Stainless steel seamless pipe is a long strip of steel with a hollow section and no seams around it.
The manufacturing process of stainless steel seamless pipe
1. Hot rolling (extruded seamless steel pipe): round tube billet → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → stripping → sizing (or reducing) → cooling → straightening → hydraulic test (or flaw detection) → marking → warehousing
2. Cold drawn (rolled) seamless steel pipe: round tube blank→heating→perforation→heading→annealing→pickling→oiling (copper plating)→multi-pass cold drawing (cold rolling)→blank tube→heat treatment→straightening → Hydrostatic test (flaw detection) → Marking → Storage.

Octagonal Pipe
HYT specializes in two primary steel pipe manufacturing techniques: seamless and welded. Each method offers unique manufacturing processes and applications, ensuring we can meet the diverse needs of various industries.
Seamless Steel Pipes
Seamless steel pipes are manufactured through processes such as hot rolling, cold rolling, or cold drawing. These methods start with a solid steel billet, heated and formed under high temperature and pressure to create a tube without any welded seams. The main advantages of seamless pipes lie in their uniformity and strength, making them ideal for high-pressure, high-temperature environments, or other demanding conditions. Due to their seamless nature, these pipes exhibit higher integrity and resistance to cracking under internal and external pressures.
Welded Steel Pipes
In contrast to seamless pipes, welded steel pipes are produced through methods like Electric Resistance Welding (ERW), Submerged Arc Welding (SSAW), or Longitudinal Submerged Arc Welding (LSAW). These processes involve curling steel sheets or coils into a tubular shape and welding them at the seam. The advantages of welded pipes include cost-effectiveness and the ability to manufacture large diameters and thick-walled pipes, crucial for many structural and transportation applications.
