Description

Alloy Steel ASME SA335 P22 Seamless Pipe For Thermal Power Plant

ASTM A335 P22 alloy steel pipe (also designated ASME SA335 P22, UNS K21590) is a ferritic chromium-molybdenum alloy steel seamless pipe, manufactured per ASTM A335/A335M standard for high-temperature service. It is commonly called “2-1/4 Chrome” in industry. This seamless pipe is produced by hot-finished or cold-drawn processes, specially designed for long-term operation under elevated temperature and high-pressure conditions, widely used in power, petrochemical and coal-chemical industries.

Chemical Composition(%):

Element Content Range (wt %)
Carbon (C) 0.05- 0.15
Manganese (Mn) 0.30-0.60
Silicon (Si) ≤ 0.50
Phosphorus (P) ≤ 0.025
Sulfur (S) ≤ 0.025
Chromium (Cr) 1.90-2.60
Molybdenum (Mo) 0.87-1.13
Nickel (Ni) ≤ 0.50

Mechanical Properties:

Tensile Strength (Ultimate) ≥ 415 MPa (≥ 60,000 psi)
Yield Strength (0.2% Offset) ≥ 205 MPa (≥ 30,000 psi)
Elongation (in 2" / 50mm) ≥ 30%
Hardness (Brinell HB) ≤ 163 HB (or ≤ 85 HRB)

Main Features of ASTM A335 P22 Alloy Steel Seamless Pipes:

  • Good Weldability
  • Superior Creep Rupture Strength
  • High-Temperature Oxidation Resistance
  • Excellent Hardenability
  • Resistance to Hydrogen Attack

Different Surface Finishes:

  • Black / As-Rolled (Mill Scale)
  • Pickled and Passivated (Bright / Bare)
  • Shot-Blasted / Sand-Blasted
  • Coated with Anti-Rust Oil/Varnish

Main Applications:

  • Power Generation Industry
  • thermal power & combined-cycle plants
  • Petrochemical & Refinery Industry
  • Coal-Chemical Industry
  • Oil & Gas Industry
  • Industrial Processing Plants
  • Pressure vessels
  • Hydrocracking and hydrotreating reactors
