Stainless Steel Pipe

Introduction to Stainless Steel Pipe Products

product overview
Stainless Steel Pipe is a corrosion-resistant pipe material mainly composed of chromium nickel alloys (such as 304, 316L), made through hot rolling, cold rolling, or welding processes. The product has the characteristics of corrosion resistance, high strength, hygiene and environmental protection, and is widely used in the fields of petrochemicals, food and medicine, energy equipment, and building decoration.

Core advantages
✅ Excellent corrosion resistance
-Containing 12% -30% chromium, passed 96 hour salt spray test (ASTM B117)
-Acid alkali/chloride corrosion resistance (316L molybdenum content ≥ 2.1%)

✅ High intensity and hygiene safety
-Tensile strength ≥ 515MPa (304), in compliance with FDA food contact standards
-Internal electrolytic polishing (Ra ≤ 0.4 μ m) to prevent bacterial growth

✅ Diversified process selection
-Seamless tube: cold drawn/hot rolled, suitable for high-pressure environments
-Welded pipe: automatic argon arc welding (TIG), with no oxidation in the weld seam

✅ Environmental protection and energy saving
-100% recyclable, with a lifecycle cost lower than carbon steel pipes
