Description
PJ-SE flange can save materials, and its structure is divided into two parts. One end of the pipe is connected with the pipe, and the other end is made into a butt welding ring.
The flange is made of low-grade material, and the pipe part is made of the same material as the pipe.
PJ-SE flange is a movable flange piece, which is generally matched with water supply and drainage fittings. When the manufacturer leaves the factory, there is a flange at both ends of the expansion joint.
It can be directly connected with pipelines and equipment in the project by bolts.

Characteristic
PJ-SE flange can save cost. When the pipe material is special and expensive, the cost of welding flange of the same material is higher.
It can be used in places that are not convenient for welding or processing, such as plastic pipes and glass steel pipes.
It is convenient for construction and can be used for the occasions where the corresponding flange bolt holes are not easy to align during connection.
Application
PJ-SE flange is widely used in pipeline engineering fields such as heat supply, heat supply, water transmission, chemical industry, natural gas, heat supply, sewage treatment, water source, bridge, steel structure, marine water transmission and piling.
