  • Packing

Reducers are usually concentric but eccentric reducers are used when required to maintain the same top-or bottom-of-pipe level.

A reducer can be used either as nozzle or as diffuser depending on the mach number of the flow.

A reducer allows for a change in pipe size to meet hydraulic flow requirements of the system, or to adapt to existing piping of a different size.

Standard: ANSI B16.9 / 16.28, ASTM A53/A106, API 5L,, ASTM/ASME SA234 WP11, WP12, WP22, WP9

Size range: 1/2 to 56 inches (DN15 to DN1400)

Pressure: SCH5 to SCH160

Types: Lare size reducers, stainless pipe reducers, carbon steel reducers, DIN 2617 pipe reducers, DIN 28011 pipe reducers

Concentric Reducer

In Concentric Reducer the reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining symmetry around the fitting. Concentric Reducers are used to join pipe or tube sections of different diameters on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters. Thus, concentric reducers connect pipes of unequal size but have a common centerline. The same fitting can be used in reverse as an concentric expander.

Eccentric Reducer

In Eccentric Reducer the reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining one side of the fitting horizontally. An eccentric pipe reducer fitting is manufactured with the smaller outlet off center to the larger end, which allows it to align with only one side of the inlet. The same fitting can be used in reverse as an eccentric expander.
