Nickel Alloy Seamless Pipes, Duplex Steel Seamless Tubing Exporter, A312 SS Seamless Pipes Leading Manufacturers.

AB Steel is one of the largest exporters, manufacturers and suppliers of seamless pipes and tubes in India. These seamless stainless steel instrumentation pipes are widely used across different industries, such as in petrochemicals, pharmaceuticals, oil and gas, pulp and paper, industrialized heat exchangers, industrial boilers, nuclear power, process pipelines, and thermal power generation, among others. Our SS Seamless Pipes and Tubes offer an inclusive range of austenitic grades like SS Seamless 304, SS Seamless 304L, SS Seamless 304H, SS Seamless 310, SS Seamless 310S, SS Seamless 316, SS Seamless 316L, SS Seamless 316H, SS Seamless 316Ti, SS Seamless 317, and so on.

Our seamless tubes and pipes are produced from high-grade materials like nickel alloys, alloy steel, carbon steel, and stainless steel, which provide ultimate strength, corrosion resistance, and durability. These tubes and pipes meet international specifications like ASTM A269, ASTM A312, ASTM A213, ASTM B167, ASME SA213, and DIN 17456, making them appropriate for worldwide markets. Offered in various grades like SS 304, 316, 321, 347, Alloy 625, Inconel 600, and Duplex 2205, our seamless tubes and pipes can handle high pressure, harsh temperatures, and corrosive chemical conditions. Their accurate dimensional tolerances, seamless surface finish, and superior mechanical properties position them well for high-stakes applications.

We provide smooth pipes and tubes of different sizes, 6mm to 610mm outer diameter (OD) with wall thickness from 0.5mm to 20mm, so that they can fit perfectly into several industrial requirements. These are very commonly used in oil and gas, petrochemical, power generation, chemical processing, pharmaceuticals, and marine applications because of their leak-free design, high tensile strength, and oxidation and scaling resistance. Our hot-finished, cold-drawn, pickled, and annealed seamless tubes come with a wide range of performance and duration benefits.

At AB Steel, we are committed to delivering top-quality seamless pipes and tubes with precise customization options, competitive pricing, and on-time delivery, making us the preferred choice for industries worldwide. We can further customize our seamless pipes and tubes in terms of thicknesses, sizes, and specifications to meet the specific requirements of our clients. We offer the same at market-leading prices.
