RFJ REDUCING FLANGES

1.WHAT ARE REDUCING FLANGES?

Reducing Flanges that are custom built to suit the varying demands of diverse industries. A complex piping network encompasses pipes of varied sizes, which may also be designed in a manner that these pipes may require frequent changes. Consequently, the pipe's diameter undergoes regular changes to adjust to the incoming stream of variations. Here is where a Steel Reducing Flange enters: it possess the ability to join pipes of varied sizes together with great ease. ANSI B16.5 Alloy Steel Reducing flanges can endure extreme pressure and are suitable for high-pressure systems like condensers and boilers.

OEM/ODM order accepted, standard or no-standard steel Reducing flanges in various specifications and standard materials can be manufactured according to customers’ requirements.
