Aditya Stainless is a reliable manufacturer and supplier of Stainless Steel Welded Tubing, proudly based in Kolkata, India. We specialize in providing top-notch welded solutions tailored to meet a wide range of industrial needs. Our Stainless Steel Welded Tubing is crafted using cutting-edge welding techniques like TIG and laser welding, which guarantee a smooth finish, precise dimensions, and impressive durability. With a variety of grades available, including 304, 304L, 316, 316L, 321, and 904L, our products adhere to international standards such as ASTM A249, A269, and A312. This makes our welded tubing perfect for both structural and sanitary applications, and it’s widely utilized across various industries.
Stainless Steel Welded Tubing is generally made up of chromium (16–20%), nickel (8–14%), and other elements like manganese, molybdenum, or titanium, depending on the specific grade. These materials provide outstanding corrosion resistance, thermal stability, and mechanical strength. Typically, welded tubing boasts a tensile strength between 500 to 750 MPa, a yield strength of around 200–450 MPa, and an elongation of 30–40%. The welding process ensures uniformity and precision, making our Stainless Steel Welded Tubing ideal for applications that require clean internal surfaces, consistent wall thickness, and dependable performance under pressure.

Stainless steel welded tubing are formed by welding stainless steel strips or plates. They offer strength, corrosion resistance, and cost-effectiveness, suitable for various industrial, commercial, and residential applications.
Stainless steel ERW (Electric Resistance Welded) tubing are produced by welding steel strips. They offer cost-effective, high-strength, and corrosion-resistant solutions for various industrial applications, providing durability and reliability.
Stainless Steel EFW (Electric Fusion Welded) tubing are produced by electrically fusing stainless steel plates or strips. They offer high precision and strength, suitable for high-pressure and demanding applications.
SS HFW (High-Frequency Welded) tubing are stainless steel tubings welded using high-frequency currents. They provide strong, precise joints, making them ideal for structural applications and high-strength requirements.
Stainless Steel butt-welded tubing are joined by aligning and welding the ends together. This method creates strong, leak-proof joints, ideal for high-pressure and high-temperature applications in various industries.
Stainless Steel laser-welded tubing use laser technology for precise, clean welds. They offer high accuracy, minimal thermal distortion, and are ideal for applications requiring tight tolerances and smooth finishes.
The tests include destructive testing methods and others which do not destroy the material but analyze the testing quality. We are developing into all modern aspects. Offering services to any customer that provides security assurance, we live achievement and a few policies such as consideration of diversity and advantage of best quality, quality reputation, and our name in the industry. Best quality speaks for itself, especially when the customer is satisfied after delivery. Logistical support at the most convenient part to ensure that shipping for emergency stock and standard packing materials is done correctly.
Stainless Steel Welded Tubing is extensively used across various industries due to its remarkable corrosion resistance, strength, and cost-effectiveness. It’s commonly found in food and beverage processing, pharmaceutical equipment, heat exchangers, automotive exhaust systems, and chemical processing. Thanks to its smooth internal surface and precise dimensions, it’s perfect for sanitary applications, fluid transport, and instrumentation lines. In construction, it serves as a key component for architectural railing systems, support structures, and piping frameworks. The tubing’s versatility also extends to applications in HVAC, marine, and the oil & gas sector.
