Description

ASTM A335 P22 Seamless Alloy Steel Pipe Chemical Process Industry Piping

Specification

ASTM A335 P22 Alloy Steel Pipe is a seamless, ferritic alloy steel pipe designed for high-temperature service, known as Chrome Moly due to its chromium (approx. 2.25%) and molybdenum (approx. 1%) content, giving it excellent strength, creep resistance, and oxidation resistance up to 650°C, making it ideal for power plants, petrochemical, and refinery applications. It's produced in various sizes, thicknesses (schedules), and lengths, often normalized and tempered, requiring hydrostatic and non-destructive testing to ensure quality for demanding environments.
