Stainless Steel Pipe

Stainless Steel Pipe is a hollow tubular profile made from stainless steel, which has the characteristics of corrosion resistance, high temperature resistance, and high strength. It can be formed through welding or seamless rolling processes and is the core pipe material for industrial fluid transportation and structural support.Widely used in industries such as petrochemicals, food and pharmaceuticals, water treatment, building decoration, machinery manufacturing, etc., it is used to transport corrosive media, high-temperature fluids, sterile materials (such as food and beverage, pharmaceutical raw materials), and can also be used as mechanical structural components, heat exchange pipelines, etc., suitable for long-term stable operation under harsh working conditions.

Common Types

  • Seamless stainless steel pipe: no welding seams, strong pressure resistance, suitable for high-pressure fluid transportation and high-temperature boiler pipelines
  • Welding stainless steel pipes: simple forming process, low cost, suitable for low-pressure fluid transportation, building decoration and other scenarios
  • Sanitary grade stainless steel pipe: mirror polished inner wall, compliant with 3A/FDA standards, used for sterile transportation in the food and pharmaceutical industries
  • High temperature resistant stainless steel pipe: added with special alloy elements, can withstand high temperature oxidation, suitable for metallurgical and thermal systems

Structural Advantages & Corresponding Benefits

  1. Inner wall mirror polishing with no dead corners structure

  • Special point: The inner wall adopts electrochemical polishing technology, with a roughness Ra ≤ 0.4 μ m, and the pipe end adopts automatic groove treatment, with no blind spots in welding.
  • Result:Low fluid resistance, no residual medium, suitable for CIP online cleaning, meeting the aseptic requirements of the food and pharmaceutical industry.

  1. Dual phase stainless steel corrosion resistant reinforced structure

  • Special point: Made of 2205 duplex stainless steel material, with a metallographic structure of austenite+ferrite duplex, it has strong resistance to pitting corrosion and stress corrosion.
  • Result: The corrosion resistance far exceeds that of ordinary 304 stainless steel, and it can adapt to harsh working conditions such as seawater and acid-base media, extending the service life of the pipe.
