Chemical Machinery

Performance characteristics:
The company research and development of rubber joint buried protective device, leave ample space around, no influence on the performance of the rubber joint displacement, and can make the rubber joint filling and external isolation, still can make free sliding on both ends of the pipe in the device, does not produce any resistance, pipeline installation after the completion of the backfill compaction ground chaoyang flat unabated, vehicles, is not affected by any stacking heavy objects, or installed equipment. The ground device for the two semicircle hollow, all rubber joints and pipes flat welding flange into the body, installed on both ends is equipped with two semicircle small plane ride in strip on both sides of the flange outer wall, both ends of facade support according to the soil depth, enough to withstand external pressure load.
This configuration is equipped with a certain amount of involution lock bolt, ready for the installation after the completion of assembly. And its installation method is: the installation of rubber joint protection device inside bitumen coating antirust dye to install lower 1/2 protection device, put the upper 1/2 protection device to tighten and lock bolt (note when installation to make the rubber joint to ensure that is at the core of device) - protection device outside the bitumen coating antirust and pure to backfill soil, bottom ramming, upper ramming to stone and cushion layer, laying on the ground (best equipped with permanent marks in appropriate locations, determine its location and position for later inspection replacement)
