Production Description

What is a blind flange?

The blind flange is a plate that attaches to a pipe end to block off the pipeline and provides easy access for cleaning, inspection, and modification. They have the same function with pipe plugs and caps, but it is detachable. It is connected to a flange or flange fittings by bolting with a gasket between them to provide a seal. And should be placed where isolation is needed, such as the nozzle of a device, before or after a shut-off valve, or between two flanges.

Carbon Steel Flanges are made up of different types of carbon steel. They come in different grades with different material compositions. All of them have high wear and tear and high toughness.

We provide Carbon steel pipe flange that comes in ASTM A105, A350 LF2, A694 F2, F46, and many other specifications. The dimensions of the flanges vary from ANSI B16.5, 16.47 series A, and B, and other international standard dimensions according to ASTM, ASME, ANSI, and DIN.
