The significance of using corrugated pipe compensator in pipeline laying.

Ripple compensator is also commonly known as expansion joint or elastic joint. It is composed of corrugated pipes, end pipes, brackets, flanges, conduits and other accessories that constitute the main body of its work. Belongs to a compensating element. Use the useful elastic deformation of the corrugated pipe of its homework subject to absorb scale changes caused by thermal expansion and contraction of pipelines, conduits, containers, etc., or compensate for axial, lateral, and angular displacement of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction. Widely used in modern industry.

In terms of heating, in order to avoid deformation or damage to the heating pipeline caused by thermal elongation or temperature stress during heating, it is necessary to install compensators on the pipeline to compensate for the thermal elongation of the pipeline, and then reduce the stress on the pipe wall and the effect force on the valve or support structure. The compensator adopts a rectangular cross-section, rounded waveform, and a single expansion joint in the pipeline receives two-dimensional displacement. The elbow joint pipeline composed of two expansion joints can accept three-dimensional displacement.

Ripple compensators are highly popular due to their many advantages and play a significant role in pipelines. Metal ripple compensators have comprehensive performance such as small space occupation, low leakage, large compensation amount, high service life, reliability, and material savings. Compared with traditional open tension compensators, they have the characteristics of small footprint, low engineering cost, and easy installation and maintenance. Compared with sleeve compensators, they have good sealing performance, The advantages of being easy to install and maintain include the following:

1. The corrugated pipe adopts a multi-layer (3-12 layers) structure, which increases the compensation capacity, saves engineering costs, and reduces engineering costs.

2. The product structure design is scientific and reasonable, and reliable measures are taken in connection, installation, diversion, guidance, and limiting. Therefore, it is widely used in industries such as petrochemicals, gas, electricity, textiles, food, and ships. Becoming a new type of component for thermal displacement compensation or earthquake resistance in pipeline systems.

Points to note for ripple compensators:

During the pressure test of the pipeline, the nuts at both ends of the compensator rod should be locked tightly, and the compensator should be fixed by the force of the rod. Although this construction method solves the problem of deformation of the compensator during pressure testing, according to the product installation manual, after the pipeline pressure test, the transportation rod is loosened, so that all moving parts of the compensator are not stuck or restricted by external components. In actual operation, due to the effect of water pressure inside the pipeline, incidents of water pipe expansion and displacement have occurred. So some construction units lock the transportation rod nuts and fix the compensator. In this way, the function of the compensator is completely lost.

Bellows compensator has unique advantages in thermal pipelines

Bellows compensator, due to its inherent flexibility, can compensate for temperature difference or other deformations between equipment and pipelines, and can also be shock-absorbing, shock-absorbing, reduce pipeline thrust on equipment, and adapt to it
