Stainless Steel Pipe

The ASTM A312 Pipe for Chemical Processing is manufactured in accordance with the internationally recognized ASTM A312 standard, which specifies seamless, straight-seam welded, and heavily cold-worked welded austenitic stainless steel pipes. Designed specifically for high-corrosion and high-temperature service in chemical plants, this pipe offers excellent resistance to a wide range of aggressive media, including acids, alkalis, solvents, and chemical intermediates. Its

Our Stainless Steel 304 Seamless Pipe is manufactured to ASTM A312 TP304 standards, offering exceptional corrosion resistance, high-temperature strength, and dimensional precision. Produced by extruding solid billet without any weld seam, this seamless stainless steel pipe is the preferred choice for critical applications in chemical processing, food & beverage, pharmaceutical, oil & gas, and power generation industries where weld integrity is a primary concern. Available in

316/316L Seamless Pipe - ASTM A312 TP316L Marine-grade Stainless Steel Pipe 316/316L stainless steel seamless pipe is an austenitic chromium-nickel-molybdenum alloy pipe known for its superior corrosion resistance, especially against chlorides and acidic environments. 316L is the low-carbon version of 316, offering better weldability and resistance to intergranular corrosion after welding. Both grades are widely used in marine, chemical, and pharmaceutical applications. Key

The Seamlessly Formed Stainless Steel Tube is manufactured using advanced seamless forming technology, resulting in a uniform wall thickness, smooth internal and external surfaces, and a complete absence of weld lines. This construction eliminates weak points associated with welded tubes, providing superior pressure resistance, corrosion resistance, and structural integrity. It is ideal for high-demand fluid transport, hydraulic systems, and precision mechanical applications.

304L Stainless Steel Seamless Pipe 304L (UNS S30403) is the most widely used low-carbon austenitic stainless steel globally. With its carbon content controlled below 0.03%, 304L Stainless Steel Seamless Pipe effectively prevents intergranular corrosion after welding, making it an ideal choice for chemical, petroleum, and pharmaceutical industries requiring highly reliable welded structures. Our seamless tubes strictly adhere to the ASTM A312 standard, manufactured using cold

Our stainless steel seamless round tubes are manufactured through precision cold drawing or hot rolling processes, resulting in a uniform wall thickness, smooth surface finish, and complete absence of weld seams. These tubes offer excellent corrosion resistance, high-temperature performance, and reliable mechanical strength. They are widely used in fluid transport, structural support, and machinery manufacturing. Various surface finishes (annealed, pickled, polished, bright

201 Stainless Steel Seamless Pipe ASTM A554 SS Tube with Mill Test Certificate The 201 Stainless Steel Seamless Pipe is an austenitic chromium-nickel-manganese alloy that provides an economical solution for moderately corrosive environments. Compared to standard carbon steel, it delivers superior oxidation resistance and significantly higher mechanical strength. At ZhongCheng, we manufacture these pipes in strict accordance with ASTM A554 / A312 standards, ensuring precise

The Cold-Drawn Stainless Steel Seamless Tube is manufactured through a precision cold-drawing process that enhances dimensional accuracy, surface finish, and mechanical properties. This method involves pulling a hollow billet through a die at room temperature, resulting in a uniform wall thickness, tight tolerances, and a smooth, weld-free surface. The cold-working process also increases tensile and yield strength compared to hot-rolled tubes. Ideal for high-pressure, high

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
