Stainless Steel Buttweld Fittings can function in a variety of application settings and are composed of several types of stainless steel. The fittings’ mechanical qualities vary depending on the quality of the materials used. These stainless steel buttweld fittings come in a variety of grades, standards, and requirements, and Rameshwar Metal is a top manufacturer and supplier of them.
The fittings can meet ASTM B366 and A403 requirements, among others. There are various kinds of applications, including high pressure, enhanced temperature, and cryogenic temperature applications. Being a top manufacturer of SS seamless pipe elbows, we create fittings with nominal diameters ranging from 1/16 to 48 inches. Additionally, there are constructed and seamless goods. Depending on the material quality and the stainless steel fittings specification, the items’ temperature varies from cryogenic to 1093 degrees Celsius.
The pressure classes of the fittings vary according to the material grade, nominal bore size and the wall thickness. The schedules range from 5s through XXS. As a leading Stainless Steel Pipe Fittings manufacturer in India we produce these fittings to operate under various environmental conditions and in different types. There are different dimensions to these fittings such as long radius, short radius, 1D, 2D and so on. The Chromium Nickel Stainless Steel 1D Bend for example is made up of a chromium nickel grade of stainless steel with a diameter that matches 1 times the outer diameter of the pipe that it is being fitted to. Please contact us for more information on the products and their prices.
