Forged Welding A105 Flange Carbon Steel ASME B16.5 WN RF SCH80

Flange, also known as flange flange or flange, is an important part of the connection between the pipe and the pipe, and is mainly used for the connection between the pipe ends. But it is also useful for flanges on the inlet and outlet of the equipment, which are used for the connection between two equipment, such as the reducer flange.

Flange connection or flange joint refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a set of combined sealing structures. Pipe flanges refer to flanges used for piping in pipeline installations, and used on equipment refer to the inlet and outlet flanges of the equipment. There are holes on the flanges and bolts make the two flanges tightly connected. The flanges are sealed with gaskets. The flange is divided into threaded connection flange, welding flange and clamp flange. Flanges are all used in pairs, wire flanges can be used for low-pressure pipelines, and welded flanges for pressures above 4 kg. A gasket is added between the two flanges and then tightened with bolts.

The thickness of flanges with different pressures is different, and the bolts they use are also different.

Just like the stainless steel flanges and high-pressure stainless steel flanges we often say, the literal difference between the two is only high-pressure, but there are obvious changes. When water pumps and valves are connected with pipelines, parts of these equipments are also made into corresponding flange shapes, also called flange connections. All connecting parts that are connected by bolts on the periphery of two planes and are closed at the same time are generally called "flanges", such as the connection of ventilation pipes. This kind of parts can be called "flange parts". But this kind of connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not good to call the water pump "flange parts". Smaller ones, such as valves, can be called "flange parts".
