Flange, also known as flange disc or flaunching. The flanges are the parts that connect the pipes to each other. Also used on equipment inlet and outlet flanges for connection between two devices, such as reducer flanges. Flange connection or flange joint refers to the detachable connection of flange, gasket and bolt as a group of sealing structures. Pipe flange shall mean the flange of pipe fitting, and shall mean the import and export flange of the equipment. There are holes in the flanges and bolts make the two flanges tighten. Gasket seals between flanges. Flange is including tapping connection (threaded connection) flange, welding flange and clamp flange.

The flanges are used in pairs. The low pressure pipe can use wire flange, and welding flanges of more than 4 kg pressure can be used. Put a seal between two flanges and secure with bolts. Flange thickness varies with different pressures and the bolts used are different. Pumps and valves, when connected to pipes, are part of these equipment, also made into a corresponding flange shape, also known as a flange connection. Where the joint parts are bolted together and closed at the same time, they are generally called "flanges". For example, the connection of ventilation pipe, this kind of parts can be called "flanges". But this connection is only a part of the equipment, such as the connection between the flange and the pump, it is not easy to call the pump "flange parts." Smaller ones, such as valves, can be called "flanged parts."

Reducer flange is used for connection between motor and reducer and between reducer and other equipment.

The way of connection: Flange connection means that two pipes, pipe fittings or equipment are fixed respectively on a flange plate, between the two flanges, add flange gaskets and bolt together to complete the connection. Some of the pipe and equipment has been equipped with flanges, is also a flange connection. Flange connection is an important connection method for pipeline construction. Flange connection is easy to use and can withstand high pressure. Flange connection is widely used in industrial piping. In the home, the pipe diameter is small and low pressure, no flange connection is visible. If you are in a boiler room or a production site, there are flanged pipes and equipment everywhere.

Welding quality: As for welded flanges, many customers wonder whether the quality of welded flanges is superior to that of forged ones. In fact, the quality of welding flange of iron plate is the same as that of welding flange of forging. But where on earth can the welding flange of iron plate be guaranteed, that is, the material of the welding flange of iron plate is the least guaranteed. Because in general process, the density of welded flange of iron plate is not a problem, but in the process of production, the blank of welded flange of iron plate is rarely tested. Therefore, the material of welding flange of iron plate without test cannot be guaranteed.

We have first-class production line and strict management system.
