dismantling joint 

dismantling joint by Falan Song telescopic joint and a short pipe flanges, other components of power transmission screw can reduce the pressure of being thrust connections (blind plates) and compensation pipeline installation error, double flanged power transmission connectors can not absorb axial displacement.
A dual role flange Transmission is mainly used for loose tube connected to pumps, valves and other accessories connected. Double Flange sets of power dismantling joint are loose telescopic joint and a short pipe flanges, power transmission and other components of the composition of the screw, it can be connected to transfer the pressure thrust piece (blind plates) and the compensation line error, can not absorb axial displacement. Important loose tube for pumps, valves, piping and other accessories connected.
Parameter Nominal by: DN20mm-DN3200mm
Working pressure :0.6-2 .5 MPA

installation instructions from the body, seals, gland, stretching tubes and other components to shorten the main components of the product are applied to both sides of the connection flanges at both ends of the pipe and flange conditioning products installed when you install the length of the diagonal Tighten evenly cover bolts using its as a whole and have a certain amount of displacement is adjusted according to the site easy to install size according to the scene when servicing. When working against the axial thrust can be transmitted to the entire pipeline.
Range 4 The product is suitable for conveying water, fresh water, hot water, drinking water, sewage, oil, fuel oil, lubricating oil, refined oil, air, gas, temperature no higher than 250 degrees of steam and particulate powder and other media .
advantages and disadvantages Advantages: double flanged dismantling joint easy to install, easy valve installation, the pipeline can withstand axial tension.http://www.gyyxgs.com
