Butt-welding flange

Butt-welding flange is to take a more complex Loudspeaker-shaped body structure, suitable for pressure or temperature fluctuations in the pipeline or high temperature, high pressure, and low-temperature pipeline, butt-welding flange is generally used for PN greater than 2.5MPa pipeline and valve connection, but also for the delivery of expensive, flammable, explosive media on the pipeline.

It is connected to the pipe end. It is mainly a part that makes the pipe and the pipe connect. There are holes on the flange, which can be threaded through the bolt, so that the two flanges are tightly connected, and the flange is sealed with a gasket. Flange fittings refer to fittings with a flange (flange or catch plate).

It can be cast from, can also be threaded or welded composition. Flange coupling refers to a pair of flanges, a gasket, and many bolts and nuts. The Gasket placed between the two flange sealing surfaces, tightens the nut, the gasket surface pressure reaches a numerical value after the deformation, and the sealing surface on uneven, so that the joint is tight and does not leak. Flange coupling is a detachable coupling. the connected parts can be divided into container flange and pipe flange. According to the structure type, there are whole flange, live flange, and threaded flange. The common integral flange has a flat welding flange and a butt welding flange.

Butt-welding flange: used for flange and pipe butt welding, its structure is reasonable, strong, and stiff, withstands high temperature and high pressure and repeated bending and temperature fluctuations, sealing. Butt-welding flanges with a nominal pressure of 0.25~2.5MPa adopt a concave-convex sealing surface.

It is often called "a high pivot" flange, its purpose is to transfer the pressure of the pipeline, thus reducing the high-stress concentration at the base of the flange. Butt-welding flange with neck is a kind of pipe fittings, which refers to the flanges with neck and round pipe transition and butt-welding connection with the pipe. Necked butt weld flanges provide sufficient strength both internally and externally to prevent leakage.
