Our ASTM A312 seamless stainless steel pipes are reliable in high-pressure and temperature applications. According to ASTM and ASME standards, these pipes are widely used in various industries, including oil and gas, petrochemical, food processing, and construction. Our seamless production process ensures a smooth inner surface, uniform wall thickness, and excellent mechanical strength.
Material and Specifications
Our A312 stainless steel pipes are available in a full range of grades, including 304, 304L, 316, 316L, meeting diverse industrial requirements. The pipes are resistant to corrosion and oxidation and are capable of withstanding harsh conditions. We offer multiple options in outer diameter (OD), wall thickness, and length, with precision finishing and strict dimensional tolerance to ensure consistent quality.
Material Composition:
Grade: 304L (Low Carbon Austenitic Stainless Steel)
Chromium: 18-20%
Nickel: 8-12%
Carbon: ≤0.03% (low carbon content reduces sensitization)
Mechanical Properties:
Tensile Strength: ≥515 MPa
Yield Strength: ≥170 MPa
Elongation: ≥40%
Hardness: ≤217 HV
Applications
These seamless stainless steel pipes are ideal for fluid and gas, boiler and heat exchanger systems, chemical processing lines, and marine piping installations. Their seamless design reduces the risk of leakage, ensures operational safety, and prolongs longevity.
Quality Assurance
Each pipe undergoes hydrostatic testing, visual and dimensional inspections, and non-destructive testing (NDT) to ensure compliance with international standards. SANVO guarantees stable quality, competitive factory prices, and fast global delivery.
