API flange

API flange is a kind of disk part, which is common in pipeline engineering. In pipeline engineering, flange is mainly used for connection of pipeline. For the pipes to be connected, a flange plate shall be installed for each type. Screw flanges can be used for low pressure pipes, and welding flanges can be used for pipes with a pressure of more than 4 kg. Add a gasket between the two flanges and fasten them with bolts. Flanges with different pressures have different thicknesses and use different bolts

API flanges are widely used in petroleum, chemical industry, nuclear power plant, food production, construction, shipbuilding, paper making and other professions. The reason why API flanges are selected for many professions is because of the functions of API flanges

API flange refers to the flange used for piping in the pipeline device, and refers to the inlet and outlet flanges of the equipment when used on the equipment. There are holes on the flange, and the bolts make the two flanges tightly connected. Hebei rolled flanges are sealed with gaskets. Flanges are threaded (threaded), welded and clamped. Flanges are used in pairs, screw flanges can be used for low pressure pipelines, and flat welding flanges can be used for pressure above 4 kg. Add a gasket between the two flanges and fasten them with bolts

Flanges with different pressures have different thicknesses, and they use different bolts. When pumps and valves are connected with pipes, parts of these equipment are also made into corresponding flange shapes, also known as flange connection. The connecting parts that are closed at the same time by bolt connection around two planes are generally called "quot;"; Flange", For example, the connection of ventilation pipe, this kind of parts can be called" Hebei elbow flange parts;. However, this connection is only a part of the equipment, such as the connection between the flange and the water pump. It is not easy to call the water pump "quot"; Flange parts;. Smaller ones, such as valves, can be called" Flange parts

API flange refers to the flange that exceeds the size specified by the relevant department of the home. Generally, it refers to flange cover with size above DN2000. Such products are all welded products without screw thread. The specifications of screw thread products are usually DN15-DN100. The large size in the pressure standard of 0.25MPa to 1.6Mpa in the flange elbow standard GB/T9119-2010 is DN2000. The big one in the 2.5MPa pressure standard is DN800. The construction company shall provide drawings for the production of such flanges. There are three production processes: forging, rolling and splicing. If the product size is too large, it can only be rolled and spliced. Its manufacturing area is mostly in Xinman Industrial Zone, Mengcun Hui Autonomous County, Cangzhou City, Hebei Province

API flange connection is to fix two pipes, pipe fittings or equipment on a Hebei flange cover respectively. The connection is completed by adding Hebei alloy flange gaskets between two flange plates and fastening them together with bolts. Some pipe fittings and equipment have their own flanges, which also belong to flange connection. Flange connection is an important connection method for pipeline construction. Big mouth
