ASTM A335 GRADE P22 COLD DRAWN ALLOY STEEL SEAMLESS PIPES/TUBES

 

 

OVERVIEW

 

ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy-Steel Pipe for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Sometimes referred to as “P Grade”, chome moly pipe is popular in P-Grades P5, P9, P11, P22, and P91. The most common use of grades P11, P22, and P91 is in the power industry and petro-chemical plants, Grades P5 and P9 are commonly used in refineries.

 

A335/SA335 Grade P22 Alloy Steel Seamless Pipes are Carbon steel pipes with addition of chromium, molybdenum, and sometimes vanadium. Chromium, or chrome, improves high-temperature strength, increases oxidation resistance and raises the tensile, yield and hardness at room temperatures. Molybdenum increases the strength, elastic limit, resistance to wear, impact qualities and hardenability. It increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is also the most effective additive for increasing high temperature creep strength, or creep resistance, and it also enhances the corrosion resistance of steel and inhibits pitting. Grade P22 is used for high temperature service applications and is tolerant to variations in its microstructure.

 

 

APPLICATIONS

 

P22 is suitable for high temperature environments including those found in the following industries:

  • Pharmaceutical equipment
  • Chemical equipment
  • Sea water equipment
  • Heat exchangers
  • Condensers
  • Pulp and paper industry
  • Off-shore oil drilling companies
  • Power generation
  • Petrochemicals
  • Gas processing
  • Specialty chemicals
