Stainless Steel Seamless Pipe ASTM A312 TP304/TP316L Schedule 40 Cold Drawn Seamless Tube

1.Product Description

Stainless steel seamless pipe is a long steel product with a hollow cross-section and no joints around its perimeter, made from metal materials. The manufacturing process employs hot rolling, hot extrusion, or cold drawing (cold rolling) techniques: solid stainless steel billets are heated, pierced, and then rolled or drawn into shape to produce a continuous pipe without any welded seams. By rolling method, it can be classified into hot-rolled, hot-extruded, and cold-drawn (cold-rolled) pipes; by metallographic structure, it includes austenitic, martensitic, ferritic, and duplex stainless steel seamless pipes. The product complies with national standards such as GB/T14976 (for fluid transportation) and GB13296 (for boiler applications), as well as international specifications including ASTM A312/A312M, ASTM A213, JIS G3456, and EN 10216-5.

2. Product Applications

Stainless steel seamless pipes are widely used as industrial pipelines and mechanical structural components in petroleum, chemical, medical, food, light industry, and instrument industries. Specific applications include:

  • Oil, gas, and chemical industry fluid transmission pipelines

  • Boiler, heat exchanger, and power generation tubes

  • Automotive and aerospace hydraulic lines

  • Hygienic flow systems in pharmaceutical and food processing plants

  • Marine and offshore pipelines

  • Building water supply systems, hot water supply, and high-pressure piping

  • Mechanical parts manufacturing and engineering structural components

  • Hydrogen energy vehicle pipeline systems

3. Product Advantages

  1. Weld-free structure: The entire pipe has no welded joints, eliminating weak points and providing a uniform structure without stress concentration.

  2. Superior pressure resistance: Capable of withstanding significantly higher pressures than welded pipes, suitable for high-pressure applications.

  3. Excellent corrosion resistance: Resistant to weak corrosive media such as air, steam, and water, as well as chemical corrosive media including acids, alkalis, and salts. Corrosion resistance depends on the content of alloying elements such as chromium, nickel, and molybdenum.

  4. Leak-proof performance: The seamless design ensures minimal leakage risk under high-pressure and high-temperature environments.

  5. High strength and durability: Features high tensile strength and yield strength, with long service life and low maintenance requirements.

  6. Smooth internal surface: Low fluid resistance, resistant to deposit buildup and contamination.

  7. Lightweight: Weighs less than solid steel materials under the same bending and torsional strength requirements.

  8. High-temperature resistance: Suitable for high-temperature thermal environments; certain grades can withstand temperatures up to 800°C and above.
