We are leading stainless steel seamless tube supplier in Mumbai

Stainless Steel Tube Manufacturer in India

The Stainless Steel Seamless Tube is comprised of several grades of stainless steel. The 304 grade is the most often used and most cost-effective for manufacturing pipes and tubes. Stainless steel tubes are available in welded and seamless varieties, with dimensions that can be tailored to specific applications. These pipes and tubes are commonly used in high-temperature and high-pressure applications such as pressure vessels and heat exchangers.

ASTM A213 SS annealed and pickled seamless tubes are available from Stainless Steel Tubing Manufacturers. These pipes and tubes have a matt surface and come in a variety of sizes. Seamless Tube Manufacturers in India manufacture annealed and pickled tubes and pipes for the offshore oil and gas industry.

Find the right dimensions for your applications in our SS tube range.

Manufacturers of Stainless Steel Tubes In India, polished stainless steel tube solution is available, which is a form of treatment that gives the product a shiny appearance. Polished SS tubes are more corrosion resistant than unpolished tubes. All Stainless Steel Tubing options can be polished to a grit of 180 or 320.

In the oil and gas industry, seamless tubing is typically used for control lines, chemical injection, and subsea safety valves. Other prominent applications for seamless tubing in the chemical process and instrumentation sector include steam and heat trace bundles, flow monitoring and sensing, and fluid and gas transfer.
