R.C. Metal Corporation is a leading Stainless Steel Buttweld Pipe Fittings manufacturer and we produce the different types of buttweld fitting such as end caps, elbows, reducers, tees, outlets, and swage nipples. There are different materials used for the production of the fitting and the SS Weld fittings are the most common. The ss are strong, high temperature tolerant and most considerably, of low cost. The Stainless Steel Pipe Fittings Manufacturer in India are used in a variety of piping applications ranging from domestic water lines to high corrosive marine and chemical applications. There are different grades of ss and the butweld fittings can be made of different types such as welded or Stainless Steel Seamless Fittings.

The different material grades along with the manufacturing types provide the specific mechanical and physical properties to the SS Buttweld Fittings. There are also different specifications of the stainless steel pipe fittings to denominate them for special applications. The ASTM A 403 Stainless Steel fittings are wrought austenitic stainless steels fitting that are meant for pressure vessel applications. It contains forged and seamless tubular products as well. The SS Pipe Fittings come under different standards and types. Depending on the standard and the type of the fitting it can range from ½ inches to 104 inches in nominal bore size.

There are different wall thicknesses to the Stainless steel welded pipe fittings and they range from sch10s through XS. The schedules are a correlation between the pipe fitting diameters and the thicknesses. The Stainless Steel Buttweld Fittings are used in off shore oil industries, petrochemicals, pharmaceutical, food processing, power plant and in marine and sea water applications. Please feel free to contact us for more information on the Schedule 10 stainless steel pipe fittings and other types with pricing.
