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.
