Neeka Tubes is a reliable supplier and exporter of Stainless Steel 316 Seamless Tubes that are made to meet all of the requirements set by ASTM A312 TP316, ASTM A269 and ASME. Our SS 316 seamless tubing is known for its resistance to corrosion, high tensile strength, and long operational life. It is the best choice for important industries like chemical processing, petrochemicals, oil and gas, power generation, pharmaceuticals, food and drink and marine engineering.
Stainless Steel 316 Seamless Tubes are made with molybdenum, which makes them more resistant to corrosion, pitting and crevice damage caused by chloride. This makes them more reliable than regular 304 stainless steel Pipes.Β We offer Stainless Steel 316L Seamless Tubes, a low-carbon type that is widely used in process industries, sanitary applications, and offshore environments. Our tubes are better at welding and don’t let carbide precipitation happen as easily.

At Neeka Tubes precision and quality are our top priorities. Every SS 316 seamless tube and pipe is manufactured to accurate dimensions, smooth finished and tight tolerances. Our tubes come in a lot of different sizes. The outside diameters (OD) range from 6 mm to 610 mm, the wall thicknesses range from 0.5 mm to 25 mm, and the schedules include SCH 5, SCH 10, SCH 40, SCH 80, SCH 160, and custom specifications.Β You can get tubes in standard lengths from 1 to 12 meters, and you can also get them in custom lengths to fit the needs of your project. Each tube undergoes a lot of tests like hydrostatic testing, eddy current examination and chemical verification to make sure it works the same way in tough conditions.
The seamless construction of these tubes guarantees uniform wall strength, exceptional pressure bearing capacity, and long term durability over welded alternatives. Whether required for sanitary applications in food and pharmaceuticals, ASTM A312 TP316 seamless tubes for chemical plants, or marine-grade 316L seamless tubes for offshore and seawater service, Neeka Tubes provides reliable supply, competitive pricing, and prompt delivery. We also have the high demand Stainless Steel 316 Seamless Pipe which meets strict industry standards for performance and dependability.
With an extensive stock range, the ability to supply custom sizes, dimensions and schedules, and dedicated technical expertise, Neeka Tubes stands as a dependable partner for premium-quality Stainless Steel 316 Seamless Tubes in India and worldwide markets.
