Axial external pressure bellows 

 Axial external pressure compensator structure features: external pressure compensator comprises one or more corrugated tubes over the middle to take over the series together, http://www.jkgssb.com/Product-20110672.html ends, respectively, within seal plate and back plate after welding, then through the tube in the tube were connected to bellows wave number more. The compensation is mainly absorbed by axial displacement, with a large amount of compensation, good insulation properties, the residual medium can be ruled out and so on. 

 Installation issues: http://www.jkgssb.com1, hydrophobic side down 2 installation, on-site installation, you must remove the rod 3, the installation media flow and the flow compensator of the same sign. 
 Axial external pressure bellows compensator with the form of multi-layer armor, wave number of 12 waves, low-carbon steel take over the connection, axial external pressure compensator device is characterized by bellows at both ends of the barrel, respectively, on the outside tube connected to the bellows a few more waves. By the role of external pressure, it can absorb a larger axial position http://www.jkbcq.com. 
 DW Axial external pressure advanced type of compensator design, reasonable structure, light weight, easy handling, with high and low temperature, high pressure, corrosion, fatigue and so on. Products widely used in petroleum, chemical, steel, metallurgy, machinery, transportation, transport, ship, port, construction, rubber, paper, textile, electric power heating network, pharmaceutical, medical and other industries.
