New type flange called anchor flange

Common flanges include flat welding flange, butt welding flange, socket welding flange, threaded flange. A new type of flange called anchor flange, anchoring flange is an engineering component. In places with less pressure can be replaced with a short tube with a thrust ring, or known as wall bushing, buried underground or life-long non-maintenance fixed pipe connection, and require a larger pressure, the conventional method Lan, can not ensure the safe and reliable work of high pressure pipe. The utility model is an axially symmetrical ring body with a flange, the symmetrical flange neck is arranged on both sides of the flange, the ports of the two flange necks are respectively welded with the port of the pipe and embedded in the anchor pile . Since the prior art bolted two flanges are merged together, the Gasket is removed to create a one-piece flange that is coupled to the pipe by welding and is secured to the anchor pile by its flange and flange body , Which can be used to fix the pipe connection. More suitable for China's "West-East Gas Pipeline Project" pipeline system, many craft station, line valve room fixed connection.

Anchor flanges are used to restrain pipeline movement caused by thermal expansion changes or external forces. The most common method of securing an anchor flange is to embed it into a concrete thrust block, thereby spreading the pipeline forces throughout a large foundation. However, anchor flanges can be secured in other ways as necessary to overcome the axial force in the pipeline.

WeldFit designs anchor flanges to satisfy ASME codes, customer requirements and best practice engineering. The most common anchor flange material is A105, but they can also be supplied using stainless or high-yield stress materials. Anchor flanges are an integral pressure retaining component of the pipeline and are therefore supplied with end weld bevels to match the pipeline wall thickness.
