Jiangsu Youying Pipe Valve Co., Ltd.

(Flange with neck flange) - Neck flange: Various types of pipe fittings produced by Yingguan Valve Parts Co., Ltd. The pipe fittings are injected and molded to have a smooth surface, uniform color, and reasonable structure. The product has the characteristics of high strength, corrosion resistance, good air tightness, long service life, and convenient installation and maintenance. The main types of pipe fittings include: flanges, joints, elbows, tees, reducers, welding rods, etc. Complete varieties and specifications, the working pressure of pipe fittings produced from the same raw materials as pipes meets the pressure requirements of the pipeline network.
The neck flange specification is a large diameter flange pipe fitting that adopts a one-time molding process and is a molded pipe fitting.
In pipeline engineering, flanges are mainly used for the connection of pipelines. Flanges with different pressures have different thicknesses, corresponding number of screw holes, different sizes of screw holes, and different bolts. When water pumps and valves are connected to pipelines, parts of these equipment are also made into corresponding flange shapes to facilitate connection, which is called flange connection.
Flange is an accessory that connects pipes to each other. It is connected to the pipe end and is also called a flange plate. During installation, insert the pipe into the flange and use a welding gun to melt the welding rod and seal the connection. This welding method is a socket-type connection. The advantage is that it is fast and convenient. The disadvantage is that if the connection port is not handled properly, it may easily pull apart under external force.
