As an important metal ripple compensator for pipeline compensation elements, the metal compensator during use needs to be regularly inspected according to the characteristics of the service pipeline and the potential for corrosion, and its suitability for continuous safe operation is judged.

Metal ripple compensator replacement should be based on the inspection results, the expected number of cycles of the equipment, the design fatigue life of the bellows and the dangerous situation in service to decide. When the metal compensator is in operation, the appearance inspection should be carried out to confirm whether the compensator can absorb thermal displacement in accordance with the design requirements, and whether the pipe support, guide pipe support and fixed pipe support can withstand the pressure thrust and other loads. During the check, ensure that the fixed pipe holder is in good condition and connected to the pipe. Whether the guide bracket is bent or twisted, and whether the pipe is allowed to move freely. The state of the insulation layer of the pipeline is able to move freely. The main working element of the metal ripple compensator is whether the bellows are deformed or unstable.

How to check the metal ripple compensator regularly

During the operation of the pipe system, regular inspections should be carried out to check whether the surface of the corrugated pipe of the metal corrugated compensator has corrosion, folds, dents, welding spatter, scratches, cracks and external residues that may interfere with the normal movement of the corrugated pipe. Whether the joint girth weld of the metal compensator structural part has cracks, corrosion and other signs.
