Description

ASTM A335 Grades P11, P22, P91, P12, P92, P5, P9 High Pressure Alloy Boiler Tubes/Pipes

1. Product Description: ASTM A335 Grades P11, P22, P91, P12, P92, P5, and P9 High Pressure Alloy Boiler Tubes/Pipes are seamless tubes designed for high-temperature and high-pressure applications typically found in power and industrial boilers. These tubes are manufactured from a range of chromium-molybdenum and other alloy steels, offering superior heat resistance and mechanical strength compared to carbon steel tubes.

2. Product Parameters:

Parameter Description
Grades ASTM A335 P11, P22, P91, P12, P92, P5, P9
Material Alloy Steel (Seamless)
Standard ASTM A335
Size Range Various diameters and wall thicknesses as per ASTM A335
Length Standard lengths, customizable upon request
Ends Plain ends, beveled ends, threaded, or socket-weld ends
Surface Treatment As-rolled, annealed, or normalized

3. Mechanical Properties:

Property Requirement by Grade
Tensile Strength Varies by grade, typically from ≥415 MPa to ≥655 MPa (60,000 to 95,000 psi)
Yield Strength Varies by grade, typically from ≥205 MPa to ≥415 MPa (30,000 to 60,000 psi)
Elongation Typically ≥20% in 50 mm (2 in) or 4D, whichever is greater
Hardness Varies depending on heat treatment and specific grade

4. Chemical Composition:

Element Typical Range (%) by Grade (Examples)
Carbon Varies, e.g., P11: 0.05-0.15
Chromium Varies, e.g., P91: 8.00-9.50
Molybdenum Varies, e.g., P22: 0.30-0.45
Phosphorus ≤ 0.025 (common across grades)
Sulfur ≤ 0.025 (common across grades)
Silicon Typically ≤ 0.50

5. Product Uses:

  • Boiler Tubes: For steam generation in high-pressure boilers.
  • Superheater Tubes: To increase the temperature of steam beyond the boiler's saturation temperature.
  • Heat Exchangers: Suitable for use in heat exchangers operating under high pressure and temperature.
  • Pressure Vessels: Ideal for construction of high-pressure vessels and reactors in petrochemical and refining industries.

6. Product Grade Standards:

  • ASTM A335: This standard covers seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes designed for high-temperature service.
