316L stainless steel welded pipe is manufactured by roll-forming stainless steel coil or plate into a tubular shape, followed by longitudinal welding. As an ultra-low carbon molybdenum-bearing austenitic stainless steel grade, it offers significantly improved resistance to intergranular corrosion after welding compared to 316 stainless steel, while retaining the excellent chloride pitting and crevice corrosion resistance provided by molybdenum.It is produced from high-quality

Large Diameter Stainless Steel Welded Pipe 304/316LLarge diameter stainless steel welded pipe is typically defined as pipe with an outer diameter exceeding 16 inches (406 mm). These pipes are manufactured by roll-forming stainless steel coils or plates into tubular shapes, followed by longitudinal welding, using processes such as SAW (Submerged Arc Welding) or LSAW (Longitudinal Submerged Arc Welding) for diameters up to 3000mm.Unlike seamless pipes, which are extruded from

ASTM A312 stainless steel pipe is a high-performance austenitic stainless steel pipe manufactured in accordance with ASTM A312 / ASME SA312, available in both seamless and welded types. This series of pipes offers excellent corrosion resistance, high-temperature strength, and good workability. It is widely used in industries such as oil and gas, chemical processing, power generation, marine engineering, water treatment, and pressure vessels. Full-size ranges, multiple grades,

The Low-Carbon Stainless Steel Pipe is specifically designed for welding applications where resistance to intergranular corrosion is critical. With a maximum carbon content of 0.03% (compared to 0.08% in standard grades), this pipe minimizes the formation of chromium carbides during welding, preventing sensitization and preserving corrosion resistance in the heat-affected zone (HAZ). Manufactured as seamless or welded and subsequently annealed, it offers excellent weldability

Welded stainless steel tube is manufactured by forming stainless steel strip into a tube shape and longitudinally welding the seam using automatic GTAW (Tungsten Inert Gas) or laser welding processes. After welding, the tube undergoes solution annealing and NDT testing to ensure weld integrity and consistent corrosion resistance. Welded tubes offer a cost-effective alternative to seamless tubes for applications not requiring the extreme pressure ratings or critical service

The Corrosion-Resistant Welded Steel Tube is manufactured from high-quality stainless steel coils, formed into a cylindrical or rectangular shape, and longitudinally welded using advanced TIG (GTAW) or laser welding technologies. Designed for environments where moisture, chemicals, or atmospheric exposure would degrade ordinary carbon steel, this tube provides excellent resistance to rust, pitting, and oxidation. It offers a cost-effective solution for applications requiring

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

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
