Seamless Pipe supplier

A seamless pipe is a long hollow tube that is produced via an extrusion process as hot steel billets are passed through it. The pipes of the stainless steel are designed in different classes to meet specific requirements. The 304 Stainless Steel Pipe is one of the most sought-after stainless steel grades. These pipes have a chemical composition of 18/8 chromium and nickel with other constituting alloys. A 316 Stainless Steel Pipe is the next most available stainless steel after the 304 grade. These pipes have a good chemical content of chromium, nickel, and molybdenum, giving them enhanced resistance to corrosive media. The Stainless Steel 316L Tube is a low-carbon alternative to the 316 grade. These tubes can be easily welded and resistant to sensitization caused by pitting. A 310 Stainless Steel Tube is an austenitic low carbon grade that works well in high-temperature applications seen in furnace parts and heat treatment equipment. The 317l Stainless Steel Tubing is a high-strength corrosion resistance tube that can be readily welded following standard procedures. This tubing has good toughness and mechanical properties. Our company is a Seamless Pipe supplier in India who have a vast stock of pipes of different sizes and shapes to meet different project requirements.

The 321 Stainless Steel Seamless Tubing is stabilized by titanium and has excellent forming properties. These tubes are suitable in temperatures up to 1500 degrees F. A 347 Stainless Steel Pipe is an alternative stabilized grade to the 304 type pipe. The pipe works well in strong oxidizing conditions and has excellent tolerance to intergranular corrosion. The Duplex Pipe is designed with a ferritic and austenitic microstructure. Their unique properties allow them to work well in refineries and oil industries. A Super Duplex Pipe has a better chemical composition than the duplex pipe, giving it better tolerances. The pipe is, however, more expensive than a duplex pipe.
