What is a flange?

Flange, also called flange plate or flange. Flanges are parts that are connected to each other between shafts and are used for connection between pipe ends, they are also useful for flanges on equipment inlets and outlets and can be used as a connection between two pieces of equipment, example reducer flanges. Flange connection or flange joint refers to a detachable connection in which flanges, gaskets, and bolts are connected to each other as a set of combined sealing structures. Pipe flange refers to the flange used for piping in the pipeline device, and when used on 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. The flanges are sealed with gaskets. Flanges are divided into threaded connection (threaded connection) flange, welding flange and clamping flange. Flanges are always used in pairs, low-pressure pipelines can use wire flanges, and welding flanges can be used with pressures above four kilograms. Add a sealing gasket between the two flanges and tighten them with bolts. Flanges of different pressures have different thicknesses and use different bolts. When water pumps and valves are connected to pipelines, some parts of these equipment are also made into corresponding flange shapes, also called flange connection.
All connecting parts that are connected by bolts and closed at the same time around the two planes are generally called “flanges”. For example, the connection of ventilation pipes, such parts can be called “flange parts”. But this connection is only a part of the equipment, Such as the connection between the flange and the water pump, It is not easy to call the water pump “flange parts”. Relatively small ones, such as valves, can be called “flange parts”. Reducer flange is used to connect the motor and the reducer, as well as the connection between the reducer and other equipment.

What is the use of flange?
Flange is a disc-shaped part, which is the most common in pipeline engineering. Flanges are used in pairs. In pipeline engineering, flanges are mainly used for the connection of pipelines. In the pipelines that require flange connection, Various devices include a flange. deficient-Pressure pipelines can use wire flanges and welding flanges with pressures greater than 4 kg. Add a sealing gasket between the two flanges and tighten them with bolts.
Flanges with different pressures have different thicknesses and use different bolts. When water pumps and valves are connected to pipelines, some parts of these equipment are also made into corresponding flange shapes, also called flange connections. All connecting parts that are bolted and closed at the periphery of the two planes are generally called “flanges”. For example, the connection of ventilation pipe, such parts can be called “flange parts”.

If the gasket is to seal successfully, the degree of imperfection on the flange face mating with the gasket must be well controlled, surface imperfections such as large nicks, grooves or scratches must be avoided, as these are difficult for the gasket to seal or fill. The surface finish of the flange can be described by “roughness, grain size and waviness”.

Recently Moresuperhard have one customer, who wanted to grind HSS pipe flange, We suggest resin CBN grinding wheel.
