What are malleable iron pipe fittings used for?
Malleable fittings are usually used to connect steel pipes. However, galvanized malleable fittings are used for galvanized pipe.
Malleable iron pipe fittings are most common among malleable fittings and are available in many different types and sizes.
What is the difference between malleable and cast iron fittings?
Malleable iron is relatively easy to machine, and it is shock resistant. Cast iron contains about two percent carbon,
which makes it stronger and more resistant to rusting. But this also makes it more difficult to machine because it is difficult to
get a smooth surface with the material.

What is the standard for malleable iron fittings?
Class 150 Malleable Iron threaded fittings have no pressure class markings. All fittings shall be threaded with American
National Standard Pipe Threads (ANSI/ASME B1. 20.1) and shall have taper threads, except wrought couplings and wrought
caps in sizes 1/8, 1/4, 3/8 and 1/2, which may have straight threads.
Forged Iron Threaded or Socket Weld Fittings are more expensive in sizes bigger than 2 inch compared to their malleable iron
or butt weld counter parts.
Malleable Iron Fitting and Threaded Pipe Fitting differ in material metallurgy, pressure class and application .
It is important to select appropriately between them for the intended application.
Malleable iron fittings, also called black iron fittings, are available up to 6 inch nominal pipe size, though they are more common to 4 inches. Malleable fittings include elbows, tees, couplings and floor flange etc.
