High-Quality ISO 9001:2015 Approved Stainless Steel Pipes & Tubes – Including Seamless, Welded, ERW, EFW Pipes and Tubes in Various Shapes, Sizes, Grades, and Customized Finishes, 1 Inch Stainless Steel Tubing, Stainless Steel Seamless Pipe Manufacturer.
Our Stainless Steel Pipes and Tubes are made from high-quality materials, ensuring they are corrosion-resistant, durable, and long-lasting. Stainless steel is ideal for applications requiring high strength and resistance to corrosion. Our products are available in 304, 304L, 316, 316L grades and more, making them suitable for a variety of industrial and commercial uses. These pipes and tubes are designed to withstand harsh weather conditions, chemicals, and high-pressure environments with ease.
Our stainless steel pipes and tubes are manufactured using advanced techniques such as seamless and welded processes. In the seamless pipe process, steel is extruded into a tube shape, which is then heated and stretched into the required diameter and length. For welded pipes, stainless steel plates are rolled and welded into pipe form. The pipes undergo stringent quality control to ensure dimensional accuracy, surface finish, and mechanical properties. Post-manufacturing, the pipes may undergo processes such as pickling, annealing, and polishing to improve their surface finish and resistance to corrosion.
Stainless steel pipes and tubes have excellent corrosion resistance due to key elements such as Chromium (Cr), which is present in 18-20% of grade 304, and Nickel (Ni) (8-10%) for strength and formability. In 316 grade, Molybdenum (Mo) (2-3%) further enhances resistance to chloride corrosion. The low Carbon (C) content in 304L reduces carbide precipitation, ensuring structural integrity at high temperatures. These pipes and tubes have high tensile strength (520 MPa for 304, 580 MPa for 316), excellent yield strength (215 MPa for 304, 240 MPa for 316), and good elongation (~40-50%), offering flexibility without breaking. With a density of 8.0-8.1 g/cm³ and low thermal conductivity (~16 W/m·K), they are ideal for heat-resistant and pressure-intensive applications.
We offer stainless steel pipes and tubes in sizes ranging from ½ inch to 24 inches (Nominal Bore) and in a wide variety of schedules, including SCH 5, SCH 10, SCH 20, SCH 40, SCH 80, SCH 160, and more. This range provides flexibility to meet the needs of various projects and applications. Whether you require high-pressure pipelines or lightweight tubes for low-pressure applications, our product range offers the perfect solution for every requirement. Our stainless steel pipes and tubes are used across multiple industries, including oil and gas, water treatment, food processing, pharmaceuticals, construction, and many more. These versatile products are known for their durability and long-term performance. We also offer customized cutting, polishing, and schedule-specific thicknesses to meet your exact specifications for any project. With superior quality and reliability, our stainless steel pipes and tubes provide peace of mind for industrial, commercial, and residential applications.
