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.
