There are two common types of flanges used for the process linkage of the 3051 pressure transmitter: coplanar flanges and traditional flanges. The common plane flange is specifically designed for the 3051 common plane pressure transmitter, and is more widely used in traditional flange applications than common plane flanges in other industries. It can meet many on-site environments with high sealing requirements. In some cases, coplanar flanges and traditional flanges can be converted and interchanged through flange adapters, which to some extent reflects the role of flanges in industrial process linkage.

Common knowledge of using flanges:
Flange diameter 250mm, nominal pressure CLASS150, full plane with neck flat welding flange, steel pipe wall thickness grade sch80, material Q235B can be marked as HG/T 20615 flange WN 250-150 FF SCH80 Q235B
Five classification methods for flanges:
Plate flat welding flange, neck welding flange, socket welding flange, welding ring loose sleeve flange. Flat welding ring loose flange, forced flat welding flange, integral flange, threaded flange, etc
1. Types of flange connections that can be secured with chain connections.
2. Divide according to standards.
3. Divided according to the standards of the mechanical industry.
4. Divided according to petrochemical industry standards.
5. Divided according to chemical industry standards.
The traditional flange used in the 3051 pressure transmitter can rotate and easily align with the bolt hole, and the sealing surface is convex, making it suitable for use on large-diameter pipelines. The use of coplanar flanges can save a lot of precious metal materials and tends to consider cost savings. The two types of flanges have a complementary relationship and complement each other's shortcomings. In use, users can decide which type to use based on the sealing conditions and position of the pipeline.
