Alloy Steel Fittings
Basic Introduction
We manufactured to ASTM A234 includes the grades of WP1, WP12 CL1, WP12 CL2, WP11 CL1, WP11 CL2, WP11 CL3, WP22 CL1, WP22 CL3, WP24, WP5 CL1, WP5 CL3, WP9 CL1, WP9 CL3, WP91, WP911, WP92. It can be widely used in moderate or high-temperature service. Our alloy steel flange products include threaded flange, weld neck flange, slip on flange, socket weld flange, blind flange, lap joint flange, plate flange. The most common product form of ASTM A234 is butt welding pipe fittings manufactured to ASME B16.9. The Butt weld alloy steel pipe fittings can be made from either seamless pipes, or fusion-welded pipes which shall be with filler metal added and shall conform to the chemical requirements of the standard specification.
