Implementation of the standard: forged flange threaded connection (WIRE) flange and welding flange. Low-pressure small diameter wire flange, high pressure and low pressure large diameter are used welding flange, different pressure flange thickness and connection bolt diameter and number are different. The implementation of standards have GB, the standard, machine, power standards, marine standards.
Forged FLANGE (flange) is also called flange or rim plate. Forged flange is produced on the basis of cast steel flange, and its strength is much higher than that of cast steel flange. The forged flange is a part connected with the pipe to the pipe end. There are perforations on the forged flange, and the bolts make the two 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 connection (Flange,joint) consists of a pair of flanges, a gasket and a plurality of 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 the deformation, and fill the uneven surface of the seal face, so that the connection is tight. A flange connection is a detachable connection. 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.
