What Is ASTM A403 ?
The pipe fittings are accessories used in commercial, industrial and domestic piping where stainless steel pipes are involved. When the pipes cannot be made as a system, the pipes are connected by various fittings that serve various purposes. ASTM A403 Fittings Supplier in Mumbai produce different fittings such as Reducers, Adapters, Couplings, Unions, Nipples, Elbows and more. We offer a competitive SS Fittings Price List to our clients in all varieties.
Can You Use Stainless Steel Fittings For Natural Gas?
The Stainless Steel Welded Fittings are the ones used with seamless pipes to maintain the integrity of the system as a whole. There are standards like the Large Diameter Stainless Steel Fittings to govern the nominal sizes of the fittings. The Mss Sp-43 Stainless Steel Elbow for example is a corrosion resistant, low pressure wrought stainless steel standard. There are Stainless Steel Pipe Fittings Manufacturers In India that are used for stainless steel piping. While Stainless Steel Welded Fittings are common, their variations such as the Fabricated SS Stub End are also used. Depending on the need of the application and the type of the fitting, the materials could differ.
