What Is Forged Flange

There are holes in the forged flange, and the bolts make the flanges tightly connected. The forged flange is sealed with gasket. Forged Flanged Pipe Fittings (flanged pipe fittings) are pipe fittings with forged flanges (flange or take). It can be formed by casting (Fig N) or by thread connection or welding. The flange joint (Flange,joint) consists of a pair of flanges, a gasket and several bolt nuts. Gasket placed in between the two flange sealing surface, tighten the nut, the gasket surface on the specific pressure to achieve a certain value after deformation, and fill the seal surface uneven place, so that the connection is tight.

A flange join is a detachable join. The connected parts can be divided into container flanges and pipe flanges. According to the structural type, there is integral flange, live sleeve flange and threaded flange. Common overall Faran welding flange and butt weld flange. Flat welding Forged flange rigidity is poor, suitable for the occasion of pressure P≤4mpa, welding flange also known as high neck flange, rigid, suitable for high pressure temperature occasions.

Forging flange sealing surface type has three kinds: The plane type seals the surface, is suitable for the pressure not high, the medium non-toxic situation, the concave-convex seal surface, applies to the pressure slightly high occasion, the tenon Groove seal surface, is suitable for the flammable, explosive, the poisonous medium and the pressure high situation. GASKET is a kind of ring which can produce plastic deformation and have a certain strength of material.
