Malleable iron pipe fitting

Short Description:

Hebei Gain offers the broadest line of malleable iron fitting sizes in both black and galvanized finishes. Every fitting is manufactured and tested to meet international quality standards. All of Class 150 Malleable Iron Fittings conform to ASME B16.3 and unions conform to ASME B16.39. All elbows and tees 3/8″ (10 DN) and larger are 100% gas tested at a minimum of 100 PSI. (6.9 bar)

The SZ reducer coupling is a class 150 malleable iron pipe fitting with female National Pipe Taper (NPT) Threads on both ends to connect two male pipes of different sizes going in the same direction. The coupling has NPT threads for creating tighter seals than straight threads. It is made of malleable iron, which has high tensile strength, and a galvanized finish that resists rust in water, air, and steam applications. This class 150 fitting meets standards ASTM A-197, ASME B 1.20.1, and ASME B 16.3 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of a maximum working pressure.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
