SMLS Con.Reducer
ASME B16.9 ASTM A403 WP304 SMLS Concentric Reducer is used to join pipes or tubes sections on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters. A WP304 SMLS Concentric Reducer can be a single diameter change or a multiple diameter change. The pipes cannot recognize what the outside configuration of the pipe reducer looks like. The pipe flow is affected by the inside diameter conical transition configuration which can be axially moved and externally reconfigured to provide for more economical reducer fittings. Thus, WP304 SMLS Concentric Reducer connects pipes of unequal size but have a common centerline. In other words, it is a type of pipe fitting with different size ends to join pipes of different diameter that joins pipe sections on the same axis.
WP304 SMLS Concentric Reducer is designed with the small and large diameters on opposite ends and joined by a cone shaped transition section. They are available in both seamless and welded construction.
 
Use of WP304 SMLS Concentric Reducer is as follows:
WP304 SMLS Concentric Reducer will transition gracefully between the piping and the pump.
The WP304 SMLS Concentric Reducer helps in transporting slurries or abrasive liquids.
They are useful in services where cavitation is present.
When transporting between flanges or pipes of different ratings and wear protection is necessary, concentric reducers are ideal.

WP304 SMLS Concentric reducers are used in discharge of the pump.
Application range: Petroleum, chemical, power, gas, metallurgy, shipbuilding, construction, etc
