Plate flanges are fabricated mainly from quality mill steel plates. They are similar to slip on flange but without the hub and also require two fillet welds. Mostly the plate flanges are produced in accordance with DIN, JIS, UNI, BS or GOST standards.
When building a pipeline, the length of the pipes used are not always known. By manufacturing the pipes separate from the plate flanges, the welders can cut the pipes to length and weld a plate flanges in place to join the pipes at any needed length. The plates can also be welded to the pipe on a slight bias, allowing two pipes to be joined that may not be precisely lined up.
