Product Characteristics

It is a new product that makes the connections among the pumps, valves, pipelines and other equipment for the pipelines.lt is connected by the bolts to form a whole with the displacement so as to be adjusted according to the site installation size during the installation and maintenance.While at work, the axial thrust can be transmitted back to the entire pipeline system. This is not only to raise working efficiency, but also to protect pipeline equipment like the pumps and valves, etc.

The importance of the expansion joints in pipeline installations. Owing to big temperature changes in connecting telescopic pipes and corrugated pipes, the use of expansion joints is a protective measure. Expansion joints are new products that make the connections among the pumps, valves, pipelines and other equipment for the pipelines. It is connected by full bolts to form a whole with the displacement. It' s easy to be installed and able to bear the axial pressure of the pipeline. So it can be adjusted according to the site installation size during the installation and maintenance.While at work, this is not only to raise working efficiency, but also to protect pipeline equipment like the pumps and valves, etc.

Technical Requirements

1. The material of the bushing and flange plate of expansion joint is 20, the bolt material is 35 and the material of brake screw is 2CR13. Rubber ring material: the medium is nitrile rubber 1-2 and the medium is water neoprene 111-2.

2. Except that the medium is oil, the steel parts of expansion joints for other applicable Sines are hot-dip galvanized. The expansion joints series products are of metal products high tensile and compressive strength, superior soft sealing performance and convenient loading or unloading process so that they are widely applied to the electric power, metallurgy chemical industry, water supply and drainage plus sewage treatments, mainly working with the connections among water pumps, valves and pipelines
