Flange, also called flange flange disk or flange. The flange is a part connected between the shaft and the shaft, used for the connection between the end of the pipe; Also useful in equipment inlet and outlet flange, used for connection between two equipment, such as reducer flange. Flange joint is an appliance used for flange sealing.
Product application:
Flange connection is an important connection mode in pipeline construction. Flange connection is easy to use and can withstand greater pressure. In the industrial pipe, in the household, the pipe diameter is small, and the low pressure, you can't see the flange connection, if you are in a boiler room or production site, there are flange connection pipe and equipment everywhere. Flange joint is widely used in engineering design, involving a very wide range of parts. It is an essential part of pipe design, pipe fitting valves, but also equipment, equipment parts (such as manholes, mirror liquid level meter, etc.) in the necessary component. In addition, other professional such as industrial furnace, thermal engineering, water supply and drainage, heating and ventilation, automatic control, also often use flange joints. Because the flange has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, freezing, health, water heating, fire, power, aerospace, shipbuilding and other basic engineering.

Flat weld flange with neck full name of flat weld steel pipe flange with neck English name: Slip-on abbreviation SO, flat weld flange with neck with plate flat weld flange as well as steel pipe, pipe fittings, etc. into the flange through the fillet weld and equipment or pipeline connection of the flange.
Butt-welding flange is a kind of pipe fittings, refers to the necked and round pipe transition and butt-welding connection with the pipe flange. Butt-welding flange is not easy to deformation, good sealing, widely used, there are corresponding rigidity and elasticity requirements and reasonable butt-welding thinning transition, welding mouth from the joint surface distance is large, the joint surface from the welding temperature deformation. Butt-welding flange is not easy to deformation, good sealing, wide range of applications, there are corresponding rigidity and elasticity requirements and reasonable butt-welding thinning transition, the welding port from the joint surface distance is large, the joint surface from the welding temperature deformation, it takes a more complex Loudspeaker-shaped body structure, suitable for pressure or temperature fluctuations in the pipeline or the pipeline or high temperature, high pressure and low temperature, generally used for the pipeline PN greater than 2.5MPa and the connection of valves; also used for conveying expensive, flammable, and low temperature pipeline, the pipeline is not easy to deformation. It is also used for pipelines conveying expensive, flammable and explosive media.
