Flanged Type Ends
Flange couplings are very extensively used across the industry, most of all to connect sections of pipelines, yet to join them with flexible hoses as well. The flange couplings are usually welded to the pipeline. Typically they are round and made of carbon steel (no coating) or zinc plated, or they are made in stainless steel. The flange coupling is sealed with a seal and screwed together with bolts on the circumference of the flange. The flange has a sealing face which is adjusted to the type of sealing that is to be used. Usually a flat seal is applied.
The flanges used in the industry are manufactured according to the requirements of standards which specify their types, dimensions, types of sealing surface, steel types, acceptable values of pressure at specific temperature.
