ASTM A213 Stainless Steel Seamless U Tube for Heat Exchangers and Boilers

Supplier of Stainless Steel Heat Exchanger Tube, Purchase Stainless Steel Reheater Tube at Discounted Price

Stainless Steel U Tube is a special type of tube production. The U tubes are made in a U shape so that there is no need for U bends or connectors to make the tube turn reverse in direction. This is advantageous as it eliminates extra fittings, connections and therefore leakages. It also secures against compromising the strength of the piping. Roopam Steel is a manufacturer and supplier of U tubes of various grades and sizes. It is also called the Stainless Steel Heat Exchanger Tube because the primary usage of the U tubes is in the heat exchanger applications. We are leading stainless steel heat exchanger tube supplier. Boiler piping also make use of these U tubes where they are known as the Stainless Steel Boiler Tube.

These are some of the high temperature applications, so that the pipes can only be made up of some high temperature service grades such as 304, 316, duplex and incoloy material. The reheater also uses the U tubes and the tubes used in this application are known as Stainless Steel Reheater Tube. There are different standards and specifications. Some specifications abide by some regulations and some regulations are state specific. The Stainless Steel IBR Boiler Tube adapts to the Indian Boiler Regulations for U tubes. ASTM A213 Stainless Steel Seamless U Tube is a specification of tubes that are seamless, either ferritic or austenitic and are low alloy steels with minimum wall thickness. The grades include 304, 304H, 304L, 310, 316 and their variations. Our 30 years of experince makes us one of the best stainless steel u tube manufacturer in India. Please contact us with your requirements and we will serve you better.
