Stainless steel seamless welded pipe is a pipe made of stainless steel with smooth internal and external surfaces and no obvious welding interfaces. Compared with welded pipes, stainless steel seamless pipes have higher pressure resistance and better corrosion resistance.

Manufacturing process:

  ● Hot rolling process: The heated billet is pierced by a perforator to form a hollow tube; then after multiple passes of rolling and stretching, a stainless steel seamless tube of the required size and thickness is finally obtained.

  ● Cold drawing process: The heated blank is pierced by a perforator to form a hollow tube; the hollow tube is then stretched by a cold drawing machine to finally obtain a stainless steel seamless tube of the required size and thickness.

Features:

  ● Seamlessness: Stainless steel seamless welded pipes are made through hot rolling or cold drawing processes and have a seamless appearance and internal structure. Compared with welded pipes, seamless pipes have better compressive strength and corrosion resistance.

  ● Corrosion resistance: Made of stainless steel, it has good corrosion resistance. It can resist the erosion of various corrosive media such as acids, alkalis, and salts, and is suitable for various harsh working environments.

  ● High strength: It has high tensile strength and compressive strength and can withstand greater pressure and load.

  ● Good sealing: It has good sealing performance and can effectively prevent liquid or gas leakage.

  ● Aesthetics: The surface is smooth and flat, and the appearance is beautiful. It is suitable for places with high appearance requirements.

Application areas:

  ● Petrochemical industry: Oil and natural gas transmission pipelines can withstand high pressure and high temperature environments and have good corrosion resistance.

  ● Pharmaceutical industry: Pharmaceutical equipment and delivery pipelines can ensure the purity and sterility of drugs.

  ● Food industry: Food processing equipment and transportation pipelines have good corrosion resistance and hygienic performance.

  ● Energy industry: The transmission pipelines of energy equipment such as nuclear power plants and thermal power plants can operate stably in high-temperature and high-pressure environments.

  ● Construction field: used in building structures, interior decoration and other fields, with good appearance and corrosion resistance.
