Stainless Steel Heat Exchanger Tube

SS 304 U Bend Tubing manufacturer in India

Stainless Steel U Tube is a special shaped tube used in applications involving high heat and pressure. These are used to avoid welding connections to form a bend or a reverse in direction. Oshwin Overseas is a PED approved Stainless Steel Heat Exchanger Tubes manufacturer in India. We produce and sell Duplex Stainless Steel Heat Exchanger Tubes as well as the austenitic stainless steel tube products. Our Stainless Steel Tube U Bend is used to reverse the direction of the fluid flow without the need for pipe fittings to do the same function.

TP316 Seamless U Tube, TP304 welded heat exchanger spiral cooling coil tube at best Price Ex. Mumbai

We also manufacture the Stainless Steel Tube Coil Heat Exchanger which can be used along with the tubes. The Stainless Steel Fin Tube Heat Exchanger is used to expel heat from the system by means of the fins that are present in the surface of the pipes. This makes heat transfer much efficient than the ordinary Stainless Steel Heat Exchanger Tubing. Our SS Finned Tube Heat Exchanger can come in different fin sizes and in different nominal sizes. We produce the pipes in different material grades. The 316l Stainless Steel Heat Exchanger is stronger and corrosion resistant than the 316 Stainless Steel Heat Exchanger but is less tough due to the lower carbon content. The 304 Stainless Steel Heat Exchanger is stronger but is less corrosion resistant than the 316 material made pipes. We also produce the Heat Exchanger With 316 Stainless Steel Shell And Tube as well as other types. You can get a full price list and catalog upon contacting us.
