Stamping flange blank is mainly formed by stamping metal or non-metal sheet metal with the pressure of a press machine through a stamping die. It mainly has the following characteristics:
⑴ Flange blanks are manufactured by stamping with minimal material consumption. Their parts are lightweight and have good rigidity. After plastic deformation of the sheet metal, the internal structure of the metal is improved, resulting in an increase in the strength of the stamped parts.
⑵ The flange blank has high dimensional accuracy, and the customized processing of Hubei flange blank has uniform dimensions with the same module and good interchangeability. It can meet general assembly and usage requirements without further mechanical processing.
⑶ Stamping flange blanks have good surface quality and a smooth and beautiful appearance during the stamping process, as the surface of the material is not damaged. This provides convenient conditions for surface painting, electroplating, phosphating, and other surface treatments.

Flange, also known as flange disc. A flange is a component that connects pipes to each other, connected to the end of the pipe; Also used for flanges on equipment imports and exports, used for connecting two devices, such as gearbox flanges. Flange connection or flange joint refers to a detachable connection composed of flanges, gaskets, and bolts connected to each other as a combined sealing structure. Pipeline flange refers to the flange used for piping in pipeline devices, and used on equipment refers to the inlet and outlet flanges of the equipment. There are holes on the flange, and bolts tightly connect the two flanges. Seal the flanges with gaskets. Flanges are divided into threaded connections (threaded connections), welded flanges, and clamp flanges. Flanges are used in pairs. For low-pressure pipelines, threaded flanges can be used, while for pressures above four kilograms, welded flanges can be used. Add a sealing gasket between the two flanges and tighten them with bolts. Flanges with different pressures have different thicknesses and use different bolts. When connecting water pumps and valves to pipelines, the corresponding flange shapes are also made for the parts of these equipment, also known as flange connections. Any connecting parts that are bolted together in two planes and enclosed at the same time are generally referred to as "flanges", such as the connection of ventilation ducts, which can be called "flange type parts". However, this connection is only a partial part of a device, such as the connection between a flange and a water pump, so it is not appropriate to call the water pump a "flange type component". Smaller components such as valves can be called "flange parts". Reducer flange, used for connecting motors and reducers, as well as connecting reducers with other equipment. The flange connection method is to first fix two pipes, fittings or equipment on a flange, add flange pads between the two flanges, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already come with flanges, which also belong to flange connections. Flange connection is an important connection method in pipeline construction. The flange connection is easy to use and can withstand high pressure.

Advantages: (1) All raw materials are made of standard square billets, which are stable and reliable;
(2) The flatness and ellipticity of the blank can be precisely controlled, achieving a reduction in processing volume;
(3) High precision in rough machining and a 50% increase in machining efficiency;
(4) High yield, with a material ratio of 1.25-1.35;
(5) Compared with traditional processes, the newly developed convex flange blank products save about 24% of raw materials;
(6) Energy saving and consumption reducing. Compared with traditional processes, the new process can save 60% of coal consumption and 40% of electricity consumption per ton of flange production;
(7) The size can be adjusted according to customer requirements. Usage: Flanged connections are widely used in industrial pipelines. In the home, the diameter of the pipeline is small and it is low-pressure, so flange connections cannot be seen. If there are flanged pipes and equipment everywhere in a boiler room or production site. At present, a small number of low-quality flange castings are cast. For small castings that require high dimensional accuracy, special casting methods such as mold casting, precision casting, pressure casting, investment casting, and centrifugal casting can be used. The disadvantage is that this type of flange is often made of "Shanxi bread iron", which is prone to leakage during use. Flange blank
Flange blank: an object used for further processing of finished flanges. Flange blank: an object used for further processing of finished flanges. Casting flange blanks
The flange produced by casting has accurate shape and size of the blank, small processing volume, and low cost, but there are casting defects (porosity, cracks, inclusions); The internal structure of the casting has poor streamline (if it is a cutting part, the streamline is even worse);

National standard flange refers to flange plates produced in accordance with the national standard GB/T 9112~9124-2010 Steel Pipe Flanges of the People's Republic of China.
The national standard for flanges was jointly released by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the National Standardization Administration of China on January 10, 2011, and has been a recommended standard implemented since October 1, 2011.
