Stainless Steel Welded Pipe

ASTM A249 / A249M is a standard specification issued by ASTM International for welded austenitic stainless steel tubes used in boilers, superheaters, heat exchangers, condensers, and hydraulic systems. These tubes are manufactured using GTAW or ERW processes and are supplied in the solution annealed condition to ensure corrosion resistance and high-temperature strength. This product covers common grades such as TP304, TP304L, and TP304H, making it particularly suitable for

ASTM A554 stainless steel welded pipe is a standard specification for welded mechanical tubing made from austenitic, ferritic, and austenitic-ferritic duplex stainless steel. Unlike pressure pipe standards (such as ASTM A312), ASTM A554 is specifically designed for mechanical applications where appearance, mechanical properties, or corrosion resistance is required, rather than internal pressure containment. ASTM A554 Stainless Steel Pipe is manufactured from flat-rolled steel

316 stainless steel welded pipe is manufactured by roll-forming stainless steel coil or plate into a tubular shape, followed by longitudinal welding. As a molybdenum-bearing austenitic stainless steel grade, it offers significantly improved resistance to chloride pitting and crevice corrosion compared to 304 stainless steel, while maintaining good high-temperature strength and workability. 316 ss welded pipe is produced from high-quality stainless steel coil using automated

ASTM A312 Welded Pipe is a globally recognized standard for austenitic stainless steel welded pipe, widely used in industrial piping systems that demand exceptional corrosion resistance, mechanical strength, and weld integrity. With core grades such as 304/304L and 316/316L, ASTM A312 welded pipe is manufactured from high-quality stainless steel coils through an automated welding process, followed by solution annealing to restore corrosion resistance and eliminate residual
