Product Description
ASTM A312 TP310S Stainless Steel Seamless Pipe For Oil and Gas
ASTM A312 TP310S is a high-alloy austenitic stainless steel pipe designed for high-temperature and corrosion-resistant applications. It is a seamless pipe manufactured under the ASTM A312 standard, which specifies seamless, straight-seam, or welded stainless steel pipes for high-temperature and general corrosion service.
Key Features:
- Material Grade: TP310S (UNS S31008)
- Chemical Composition: High chromium (24-26%) and nickel (19-22%) content, providing excellent resistance to oxidation and corrosion at elevated temperatures.
- Heat Resistance: Exceptional resistance to oxidation up to 1100°C (2012°F) in continuous service and 1035°C (1895°F) in intermittent service.
- Corrosion Resistance: Superior resistance to intergranular corrosion, pitting, and stress corrosion cracking, even in harsh environments.
- Mechanical Properties:
- Tensile Strength: ≥515 MPa (minimum)
- Yield Strength: ≥205 MPa (minimum)
- Elongation: ≥35%
- Seamless Design: Ensures uniform strength, reliability, and leak-free performance, especially under high-pressure conditions.
- Applications: High-temperature environments such as heat exchangers, furnace components, chemical process equipment, and power generation.
