The installation method of curved pipe pressure balance corrugated compensator

Oct. 15, 2021

What is curved pipe pressure balanced corrugated compensator?

 

Curved pipe pressure balanced corrugated compensator is also called curved pipe pressure balanced expansion joint, curved pipe pressure balanced expansion joint, installed in the bend of the pipeline or equipment connected to the space pipeline. Curved pipe pressure balanced corrugated compensator can compensate axial displacement, lateral displacement, without internal pressure thrust on the pipeline system or other equipment, installed in the bend of the pipeline or the pipeline of the space connected with the equipment, can quickly eliminate the system pressure wave vibration caused by start-up, water stop, etc., and can absorb vibration and reduce noise to ensure the safe operation of equipment.

 

The front part (channel end) of the bent pipe pressure balance type corrugated compensator has two working bellows, which can absorb the lateral displacement produced from the bent pipe section, and the rear part (balance end) has a balance bellows, which can absorb the axial displacement from the straight pipe. When the bending tube produces and lateral displacement, the spherical nut wire on the big tie rod rotates around the spherical washer. At the same time, the large tie rod is subjected to internal pressure thrust. Compensator channel end of the two bellows can compensate the bending pipe section caused by the transverse and longitudinal mutual movement, balance end of the balance bellows can compensate the axial displacement of the straight pipe section.

Application of curved pipe pressure balance corrugated compensator


The curved pipe pressure balanced corrugated compensator is suitable for bends or space pipelines connected with equipment. It compensates axial displacement and lateral displacement. It is commonly used in load-sensitive piping systems, such as pumps, compressors and turbines. It is suitable for petrochemical, steel, electric power, non-ferrous metals and other sectors. The curved pipe pressure balance corrugated compensator can be installed correctly to achieve the use effect.

 

Precautions for the installation and use of the bent pipe pressure balance corrugated compensator

 

●Curved pipe pressure balanced corrugated compensator (expansion joint) is generally applied to straight pipelines overhead and installed horizontally.

●All small ties must be removed after the installation of curved pipe pressure balanced corrugated compensator (expansion joint).

●In order to reduce the elastic reaction force of the bellows expansion joint on the support, it should be communicated with the manufacturer before installation to pre-pull or pre-pressure of such bellows expansion joint (which can be achieved by adjusting the small ties on it).

●Pay attention to protect thin-walled parts such as bellows from damage such as impact, scratch, arcing, and welding splash during installation.

●If there is a flow direction mark, the media flow direction should be consistent with the media flow direction during installation.

●Before the guide bracket and fixed bracket are properly installed, they should be installed in strict accordance with the piping system design drawings.7. No pressure test should be performed until all guide brackets and fixed brackets are properly installed. If a sectional pressure test is performed on the entire piping system, confirmation of the corrugated compensator manufacturer is required.
