Duplex steel flanges, as the name suggests, are produced from raw materials such as duplex steel bars, ingots, or plates, commonly referred to as duplex steel flanges. Flanges, also known as flange plates or flanges, are components that connect pipes to each other. They are connected at the pipe ends. Flanges have holes for bolts,…
Necked butt welding flanges are a type of flange fitting that can be numbered and produced according to certain methods and standards, playing an important role and value in various fields and industries, ensuring significant contributions during use. Gaskets are used for sealing between flanges. Flange fittings refer to fittings with flanges. Necked butt welding…
The corrosion prevention at pipeline flange connections has always been a technical challenge. The process pipelines and equipment at gas transmission stations are generally arranged outdoors and installed on the ground, using coatings for corrosion prevention. These coatings are required to have good adhesion to metal surfaces, be waterproof, resist atmospheric corrosion, and have good…
Flange connections are one of the main forms of connection for gas pipelines and equipment. The connection flanges primarily rely on the preload generated by their connecting bolts, achieving sufficient working sealing pressure through flange gaskets to prevent gas leakage and ensure sealing. Based on years of operational experience, the main reasons for pipeline flange…
1. The definition difference between flanges and blind plates Flange: It is a disc-shaped component used for connecting pipes, equipment, or valves, achieving sealing and fixation through bolts and gaskets. Common types include flat welding flanges, butt welding flanges, socket welding flanges, threaded flanges, and loose flanges. Blind plate: A blind plate is a special…
Flange, also known as flange flange disc or flange. Flange is a shaft and shaft interconnecting parts, used for connection between pipe ends; also used in equipment import and export of the flange, used for the connection between two devices, such as reducer flange. Flange connection or flange joint, refers to the flange, gasket and…
