REDUCING & EXPANDING FLANGES
REDUCING & EXPANDING FLANGES
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 Stainless Steel Reducing Flange enters: be it in Monel, Inconel, Hastelloy, Carbon Steel or Alloy Steel, it possesses 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
