Widely used in the connection of various pipes, containers and other equipment.
Flange is an important connection device, which is widely used in the connection of various pipes, containers and other equipment. According to different use requirements and characteristics, there are many types of flanges. The types and application fields of flanges will be described in detail below.
Types of 1. flanges
1. Flat welding flange:
Flat welding flange is a common type of flange, and its connection method is bolt connection. It is suitable for the connection of medium and low pressure pipelines, and has the advantages of simple manufacture and low cost.
2. Butt welding flange:
Butt welding flange is a kind of high strength flange, and its connection mode is butt weld. It is suitable for the connection of high pressure and high temperature pipelines and has good sealing performance.
3. Cast iron flange:
Cast iron flanges are mainly used in the foundry industry and are usually used to connect cast iron pipes and valves. It has the characteristics of corrosion resistance and wear resistance, and is suitable for the working environment of corrosive media.
4. Stainless steel flange:
Stainless steel flanges have excellent corrosion resistance and high temperature resistance, and are widely used in chemical, petroleum, food and other industries.
5. Threaded flange:
The threaded flange is fastened by threaded connection, which is suitable for pipeline connection with smaller diameter, such as the transportation of natural gas, water and other media.
2. Application Areas
