What Is Malleable Iron Fittings?

Malleable iron fittings are used to connect piping grades of different sizes, allowing it to route, change the direction, and branch the connection. The malleable steel fittings are lighter and are usually available in pressure classes of 150# and 300#. These malleable galvanized fittings are used in system where the plumbing pressure is up to 300 psi. Malleable fittings can be easily deformed as they are easily hammered or rolled without cracking the metal. Our institution is malleable iron fittings manufacturer in India who have a vast stock of fittings that are of different sizes and shapes to suit different applications in the oil and gas industry.

The malleable iron threaded fittings have threads on their surface that allow them to be joined to subsequent grades easily. These fittings are durable and can be easily fitted to the pipes. They are designed in black and galvanized finishes. Black malleable fittings possess good corrosion resistance properties and are designed with a dark-colored iron oxide coating. These fittings are designed in sizes up to 6 inches. The malleable iron screwed pipe fittings are produced in the shape of elbow, tee, coupling, crosse, union, adaptor, etc. The fittings are reliable and are very durable for long periods. The Malleable Cast Iron Pipe Fittings work well in different pressures and temperatures. These fittings possess a sophisticated and metallurgical structure, allowing them to create a strongly bonded metal grade.
