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.

Below is a detailed table summarizing the thermal, physical, and mechanical properties of ASTM A213 TP310S:

Property Type Property Value Significance
Thermal Properties Thermal Conductivity 14.2 W/m·K (20°C), 19 W/m·K (500°C) Moderate conductivity for high-temp stability.
Coefficient of Thermal Expansion 16.1 × 10⁻⁶ /°C (20–1000°C) Low expansion reduces thermal distortion.
Specific Heat Capacity 500 J/kg·K (20°C) Efficient heat absorption.
Melting Point 1400–1450°C Stable at extreme heat.
Oxidation Resistance Continuous: 1100°C; Intermittent: 1035°C Excellent performance in oxidizing atmospheres.
Physical Properties Density 7.9 g/cm³ High strength-to-weight ratio.
Modulus of Elasticity 200 GPa High rigidity for dimensional stability under load.
Electrical Resistivity 0.78 μΩ·m (20°C) Good resistivity for high-temperature electrical systems.
Magnetic Permeability Non-magnetic (annealed condition) Suitable for non-magnetic applications.
Mechanical Properties Tensile Strength 515 MPa (min), 735 MPa (max) High durability in high-stress conditions.
Yield Strength (0.2% offset) 205 MPa (min) Resists deformation under load.
Elongation 35% (min) High ductility for forming and shaping.
Hardness 217 HBW, 95 HRB Balances wear resistance and machinability.
Creep Strength Excellent at elevated temperatures Prolonged use in high-temperature environments.
Impact Strength High Toughness at both room and elevated temperatures.

Applications of ASTM A312 TP310S Pipe:

  • Petrochemical and Chemical Industries: Handles corrosive materials and high-temperature fluids.
  • Power Plants: Suitable for superheater and reheater tubes in boilers.
  • Furnaces and Thermal Equipment: Used in environments requiring excellent heat resistance.
  • Food and Beverage Industry: For processing environments requiring cleanliness and corrosion resistance.
