DN200 double flange water pipe fitings ductile iron expansion dismantling joint

1. The product is made up of metal casting or welding. The trapezoidal rubber sealing ring is used in the loose sleeve part under the action of pressure cap and bolt.

2. Using the elastic deformation principle of rubber compression. The sealing ring is forced to be deformed between the outer wall of the expansion pipe of the joint body for static sealing.

3. Metals and seals should be selected strictly according to their performance and user requirements. The material is externally coated with high strength anticorrosive paint. The connecting bolts of each part are made of high strength carbon steel or stainless steel. Because there is a certain gap between the body and the telescopic tube, it has a certain axial and radial displacement.

4. In the pipeline, it can effectively compensate and relieve the thrust of the pipeline and blind plate, and also facilitate the installation, maintenance and replacement of pumps and valves. It is the most ideal supporting product in the pipeline installation and operation industry.

1. Because this series of products belong to metal products, they have higher tensile and compressive strength, superior soft sealing performance, convenient loading and unloading and other functions, and are often used in power and metallurgy.

2. Water supply and drainage and sewage treatment industries mainly act on the connection between pumps and valves and pipes.

3. It has a certain multi-directional displacement effect in the pipeline operation, which can alleviate the blind plate thrust in the pipeline operation and play a certain protective role, especially for the installation and maintenance of the pipeline. However, the force transfer joint should be used at the outlet of the pump and the corner of the pipeline, because the force transfer joint can push the blind plate thrust when starting the pump through the force transfer bolt (i.e. the whole wire bolt). Conduction to all parts of the pump and pipeline, to avoid thrust concentrated in the pipeline or near the end of the pump impact damage equipment.
