UNS31803 GR2205 CON RED
ASTM A815 UNS31803 GR2205 CON RED is used to join pipe or tube sections on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters. A pipe 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, seamless concentric reducers connect 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.
ASTM A815 UNS31803 GR2205 CON RED 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.
ASTM A815 UNS31803 GR2205 CON.RED will transition gracefully between the piping and the pump.
The UNS S31803 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, UNS S31803 seamless concentric reducers are ideal.
UNS S31803 Concentric Reducer is used in discharge of the pump.
Application range: Petroleum, chemical, power, gas, metallurgy, shipbuilding, construction, etc
