ASTM A335 Alloy Pipes
ASTM A335 alloy pipes from Big Co., Ltd. are seamless ferritic chromium-molybdenum steel pipes designed for high-temperature service in power plants, refineries, and petrochemical facilities. The material is a Cr-Mo alloy with grades P5, P9, P11, P22, and P91, offering superior heat resistance and mechanical strength at elevated temperatures. Sizes range from 1/2 inch to 24 inch NPS, with wall thicknesses from 7 mm to 60 mm and lengths up to 12,000 mm for hot-rolled and cold-drawn variants, extending to 16,000 mm for certain cold-drawn and hot-rolled configurations.
The chromium content in these grades varies from 1.00% to 10.00%, while molybdenum ranges from 0.44% to 1.13%, providing enhanced creep resistance and durability under thermal stress. P91 and P92 grades include additional alloying elements like vanadium, niobium, and tungsten for improved tensile strength and rigidity, with typical values for P91 reaching up to 760 MPa. Surface treatments such as oil-dip, varnish, passivation, and epoxy coating are available, along with beveled ends and protective packaging for export.
These pipes are critical for boiler and heat exchanger systems, where reliability under pressure and temperature fluctuations is essential. Big Co., Ltd. supplies them globally with Mill Test Certification, ensuring compliance with ASTM A335 standards for chemical composition, mechanical properties, and non-destructive testing. Buyers typically source these for large-scale industrial projects, confirming specifications like tensile strength, yield strength, and elongation before procurement.
