Process: In fact, it is precision model forging, sometimes called precision pressing or embossing. Putting the forging that has been model forged into a precision die groove and applying pressure to make it produce slight deformation, so as to obtain high-precision size and smooth surface forgings. The neck flange is a part that is connected to each other between the shaft and the shaft, and is used for the connection between the pipe ends; it is also useful for the flange on the inlet and outlet of the equipment, and is used for the connection between two equipment, such as the flange of the reducer. . Neck flange connection or flange joint refers back to the detachable connection of flange, Gasket and bolt as a group of combined sealing structure.

Pipe flange refers back to the flange used for piping in the pipeline installation, And used on the equipment refers to the inlet and outlet flange of the equipment. There are holes in the flange, and the bolts tightly connect the two flanges. Since American standard flange forgings are made into parts, their stress, importance, and working conditions are different during use, and their materials and smelting metal processes are also different. Therefore, different parts are based on the above conditions and in accordance with the requirements of this department. Divide forgings into categories, different departments and different standards have different classifications for forgings. Operation control methods include: manual, gear transmission, electric and so on. Among transmission towers of various materials, steel pipe towers are more and more widely used due to their superiority.

In industrial pipelines, forged flange connections are widely used. Welders engaged in the welding of pipe fittings should pass the examination of the quality and technical supervision department and obtain the corresponding qualification certificate before they can engage in the welding of relevant steel types. The welded pipe fittings used in some industries must obtain the welder examination and welding process stipulated by the industry Evaluation, such as the welding of marine pipe fittings, must obtain the welder examination and welding procedure evaluation of the corresponding classification society.
