The Mill Finish Stainless Steel Welded Square Tube is manufactured from high-quality austenitic stainless steel coils, formed into a square profile, and longitudinally welded using TIG or ERW processes. The mill finish surface is the condition directly after welding and annealing, characterized by the presence of a thin oxide scale and the absence of any subsequent mechanical or chemical surface treatment. This economical finish is ideal for industrial applications where

The High-Temperature Stainless Steel Pipeline is engineered to withstand extreme thermal conditions while maintaining mechanical strength, oxidation resistance, and structural integrity. Manufactured from specialized austenitic stainless steel grades, this seamless pipeline is designed for continuous operation in elevated temperature environments up to 1150°C (2100°F), depending on the selected grade. Its excellent creep resistance and thermal fatigue properties make it the

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

2205 duplex stainless steel pipe offers a balanced combination of high strength and excellent corrosion resistance, making it the preferred choice for industries such as oil & gas, chemical processing, marine engineering, and desalination plants. With a duplex microstructure (approximately 50% austenite + 50% ferrite), 2205 provides nearly twice the yield strength of common austenitic stainless steels like 304 or 316L, while maintaining good weldability and fabricability. Key

Low carbon seamless stainless pipe is a specialized category of austenitic stainless steel pipe with a maximum carbon content of 0.030%, significantly lower than standard grades which contain up to 0.080% carbon. This reduced carbon content provides critical advantages for welded assemblies and applications involving exposure to corrosive media in the as-welded condition. The primary benefit of low carbon stainless steel is its resistance to sensitization – the precipitation

The Stainless Steel ERW (Electric Resistance Welded) Pipe is manufactured by cold-forming stainless steel coils into a cylindrical shape and welding the longitudinal seam using high-frequency electric resistance welding technology. This process produces a pipe with a narrow, uniform weld seam that is virtually indistinguishable from the base metal after proper heat treatment. ERW pipes offer an excellent balance of corrosion resistance, dimensional accuracy, and cost

Welded duplex stainless steel pipe is manufactured by forming a flat strip of duplex stainless steel into a cylindrical shape and welding the longitudinal seam. This process produces a pipe with excellent dimensional accuracy, consistent wall thickness, and a cost-effective solution for corrosive service applications. Our welded duplex pipes are produced using advanced welding techniques including ERW (Electric Resistance Welding), EFW (Electric Fusion Welding), and DSAW

The Acid-Resistant Stainless Steel Tubing is specifically engineered to withstand highly aggressive acidic environments, including sulfuric, hydrochloric, nitric, phosphoric, and organic acids. Manufactured from high-performance austenitic and duplex stainless steel grades with elevated chromium, nickel, and molybdenum content, this tubing provides exceptional resistance to general corrosion, pitting, and intergranular attack. Its seamless construction ensures uniform wall
