Stainless Steel Blind Flange Blank ANSI JIS BS DIN GOST 1.4301/1.4307

Product Data

Product Introduction

Blind flange, also known as a blank flange, is a type of flange without a hole in the middle, which is a solid disk that can be used to seal pipeline openings.

The function of the blind flange is the same as that of the head and pipe cap, but the difference is that the blind seal is a detachable sealing device, and the seal of the head is not prepared to be opened again. On the one hand, blind flanges are more flexible in operation.

There are many types of sealing surfaces for blind flanges, including flat, convex, concave convex, tenon groove, and ring connection surfaces.

In terms of materials, blind flanges actually include carbon steel, stainless steel, alloy steel, copper, aluminum, PVC, and PPR. Carbon steel and stainless steel have the highest usage rate among them.

Stainless steel blind flange is a common pipe connection accessory used to close non operational or temporarily closed pipe openings in pipeline systems. It usually consists of a flat circular blind plate body and protruding connecting bolt holes.

Stainless steel blind plates are mainly made of stainless steel materials, with common stainless steel materials such as 304, 316, 321, etc.

Application
Stainless steel blind plates are mainly used for sealing operations in industrial pipeline systems, such as pipeline maintenance, equipment maintenance, system testing, etc. It can seal the pipeline mouth to prevent medium leakage.A

Advantages and Disadvantages
