What Is ASTM A335 P22 pipe ?
A335/SA335 grade P22 alloy steel seamless pipe are carbon steel tubes with chromium, molybdenum, and sometimes vanadium added. Chromium or chromium can improve high temperature strength, increase oxidation resistance and improve tensile strength, yield strength and hardness at room temperature. The chemical composition in P22 seamless pipes are carbon 0.05-0.15%, manganese from 0.30-0.60%, silicon up to 1%, chromium up to 2.6%, and molybdenum and silicon like other small elements for the chemical balance. An Alloy Steel Pipe is used in applications which require moderate corrosion resistance properties with good durability and at an economical cost. To simply put it, alloy pipes are preferred in those areas where carbon steel pipes may fail. There are two classes of alloy steels - high alloys and low alloy steels.
ASTM A335 specificaton covers nominal wall and minimum wall seamless ferritc alloy-steel pipe intended for high-temperature services. The pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar formtion operations, and for fusion welding. Selection will depend upon design, mechnical properties, service conditions and high-temperature characteristics.
