Product Description

Product Description

Flange is a device used to connect pipes, pipe fittings, containers and other equipment, usually used in petroleum, chemical, electric power and other fields. According to different classification methods, flanges can be divided into the following types:
According to the different materials, flanges can be divided into carbon steel flanges, stainless steel flanges, alloy steel flanges, copper flanges, plastic flanges.
Carbon steel flange: is a kind of flange made of carbon steel material, it is usually used for general industrial pipe connection.
Stainless steel flange: It is a flange made of stainless steel material, which is usually used for the connection of corrosive media pipelines.
Alloy steel flange: is a kind of alloy steel material made of flange, it is usually used for high temperature and high pressure pipe connection.
Copper flange: It is a flange made of copper material, which is usually used for the connection of water supply pipes.
Plastic flange: is a kind of flange made of plastic material, it is usually used for the connection of plastic pipes.

The main characteristics of the flange include its simple structure, easy processing, easy anti-corrosion lining, and can withstand greater pressure. flange consists of a pair of flanges, a gasket, and several bolts and nuts. Tighten the nuts to deform the gasket when the specific pressure on the surface reaches a certain value, and fill the uneven part on the sealing surface to ensure tight connection. The sealing surface of the flange has a variety of forms, such as sudden surface, concave and convex surface, mortise and groove surface, etc. Each form is suitable for different sealing requirements and working environment.  
Flange sealing surface forms include:
surface (RF) : the sealing surface is flat, large contact area, suitable for low pressure occasions.
concave and convex surface (MFM) : by the convex and concave together, can prevent leakage, withstand greater pressure and impact.
mortise and groove surface (TG) : the sealing surface is narrow, suitable for high pressure and high sealing requirements.
full plane (FF) : simple structure, suitable for the occasion of low pressure and temperature.
ring connection surface (RJ) : good sealing performance, suitable for high temperature and high pressure conditions.
In addition, flanges are widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, health, water heating, fire, power, aerospace, shipbuilding and other fields, because of its good comprehensive performance and widely used.
