Curved pipe pressure balanced bellows welding process in response to test the following: Structural features: the front compensator (channel side) has two working bellows, behind (balance side) there is a balanced bellows. When the transverse displacement of large rod bends on the surface ?????????? nut rotation around spherical washers. At the same time withstand large pressure thrust rod. Compensation features: two working bellows can compensate for bending pipe compensator end of the tunnel to produce lateral displacement, balanced side balanced bellows can compensate for straight pipe ??? axial displacement Installation instructions:? Curved pipe pressure balanced bellows mounted on the corner pipe or conduit connected to the device space. He can compensate for axial displacement, transverse displacement, piping systems or devices, without affecting the internal pressure generated thrust. Commonly used in pumps, compressors, turbines, and other sensitive payload piping, shock-absorbing noise and ensure safe operation of equipment. After the on-site installation, need to remove a small lever.
