  stainless steel seamless pipe TP304

  TP304 stainless steel seamless pipe complies with ASTM A312. It is austenitic stainless steel with good resistance against atmosphere, fresh water and weak acid‑alkali corrosion. It features favorable high‑temperature oxidation resistance, excellent toughness and weldability, easy for fabrication and bending. Both inner and outer surfaces are smooth with stable mechanical properties and reliable pressure‑bearing performance. It is widely applied in water‑supply & drainage, HVAC, general chemical and food‑grade fluid transmission pipelines.
• 
  TP 304L stainless steel seamless pipe

  TP304L is low‑carbon austenitic stainless steel seamless pipe. With lower carbon content, it delivers outstanding intergranular corrosion resistance. It possesses good toughness and excellent weldability, hardly suffering intergranular corrosion after welding. It has stable mechanical properties, good resistance to atmosphere, fresh water and weak acid‑alkali. Smooth inner and outer surfaces with reliable pressure‑bearing capacity. Suitable for welding conditions, water supply‑drainage, chemical and food‑grade fluid pipelines.
• 
  TP 316L stainless steel seamless pipe

  TP316L is low‑carbon molybdenum‑bearing austenitic stainless steel seamless pipe. With molybdenum added, it performs better in chloride‑ion corrosion resistance than 304 series. It has good intergranular corrosion resistance and excellent weldability with stable corrosion‑resisting performance after welding. It features reliable mechanical properties and smooth inner & outer surfaces, resisting seawater, salt spray and weak acid‑alkali media. Widely used in chemical, seawater treatment, food‑grade, marine and pressure‑bearing pipelines.
