Industrial Pressure Balance Type Pipe Expansion Joint Bellow Compensator

Curved tube pressure balance type expansion joint

Product description

Curved tube pressure balance expansion joint is suitable for petrochemical, steel, power, non-ferrous metal and other departments;Balance ripple compensators are used in pumps, compressors, steam turbines and other load-sensitive piping systems.

Bend pressure balance type expansion energy compensation axial displacement, lateral displacement, without pressure within the piping system or other equipment to produce thrust, bend, or with the device installed in the pipe connection line of the space, can rapid attenuation due to the vibration stress wave in the system such as start, stop, eliminate water machine, and can absorb vibration noise, guarantee the equipment operation.

There are two working bellows in the front (channel end) and a balance bellows in the rear (balance end).The spherical nut wire on the large pull rod rotates around the spherical washer when the bending pipe is produced and transversally displaced.At the same time, the large pull rod is under internal pressure.The two bellows at the channel end of the expansion joint can compensate for the lateral displacement of the curved section, and the balance bellows at the balance end can compensate for the axial displacement of the straight section.

Notes for installation and use of pressure balance type expansion joint of curved pipe

1. Curved tube pressure balance type expansion joint is generally applied to the straight pipe line overhead and installed horizontally.

2. After installing the pressure balance expansion joint of the pipe, all the small tie rods shall be removed.

3. In order to reduce the elastic reaction of the bellows expansion joint to the support, the bellows expansion joint can be pre-pulled or pre-pressed before installation (it can be achieved by adjusting the small tie rod on it).
