Inconel 625 Blind Flanges Specification

A blind flange is a solid disk used to block off a pipeline or to create a stop. The blind flange is machined in the same manner as a regular flange with the mounting holes around the perimeter and the gasket sealing rings machined into the mating surface. The difference is that a blind flange has no opening to allow fluid to pass through. The blind flange can be inserted between two open flanges and used to block off the flow of liquid through a pipeline.

We at Siddhagiri are able to accurately supply and ship the Inconel 625 Blind Flanges order overseas on time.

Product Name: ASTM B366 Inconel 625 Blind Flanges

Inconel 625 Blind Flanges Blind Flanges

Specifications : ANSI B 16.5 from 1/2″ to 24″ and classes150 to 2500 (complete range)

Applications : Used in quick assembly to save the cost, these are also used in less strict requirements in terms of length of pipe section.

We also supply Inconel reducing flanges (WN, SW, SO, Thrd) with the hubs or made from blinds (in the cases of SO or Thrd). B16.5 gives rules for how we do the reductions.
