ASME B16.5 PN16 Stainless Steel Blind Flange Forged Flange Used In Industrial Pipelines

Flange cover is also called blind flange or blind plate. It is a flange without a hole in the middle, which is used to seal the pipe plug. The function is the same as the welding head and the threaded pipe cap, except that the blind flange and the threaded pipe cap can be removed at any time, while the welded head cannot.

Introduction

There are many types of sealing surface, including full plane, raised surface, concave-convex surface, tongue and groove surface, ring connection surface.
