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.

Certified stainless steel billets are selected according to ASTM, ASME, and EN standards.
Billets are heated and forged into the required flange shape for maximum strength.
Precision machining creates the bore, facing, bolt holes, and required dimensions.
Stress relieving and solution annealing are performed whenever required.
PMI, dimensional inspection, hydrostatic testing, and NDT ensure product quality.
Flanges are cleaned, pickled, passivated, and finished as per customer requirements.
Each flange receives grade, size, heat number, and standard identification markings.
Products are packed securely with flange protectors, wooden pallets, and export-ready crates.
When is it appropriate to use a Reducing Flange instead of a Buttweld Reducer?
A Reducing Flange is a cost-effective solution when transitioning from a larger pipe to a smaller pipe, such as from a 4-inch line to a 2-inch valve, especially where installation space is limited. It combines the flange and reducing function into a single component, provided the application does not involve excessive turbulence or flow restrictions.
Can Reducing Flanges be used as Blind Flanges?
Not exactly. Although a Reducing Flange is structurally similar to a Blind Flange, it includes a central threaded or weldable bore that connects the smaller branch pipe, whereas a Blind Flange has no center opening and is used to completely seal the pipeline.
