What are the causes of damage to the bellows compensator
As the corrugated part of the bellows compensator is relatively fragile and may be damaged by violent bumps, the packaging and transportation of the bellows compensator may seem insignificant. In order to protect the universal bellows compensator from damage during transportation and storage, the universal bellows compensator should be packed reasonably. For example, pack it in wooden boxes and fill the gaps with objects such as shredded paper and foam. Wrap the corrugated part with wrapping paper to prevent contact with the box. In the open storage in the open environment, the packaging should pay attention to moisture-proof measures. General corrugated compensator should be set during transportation. Transportation fixtures are rigid supports that protect the total length of the general corrugated compensator such as transport bolts and angles from being changed. The fixture can also be used to pre-stretch or compress the general corrugated compensator so that its installation length is equal to the design value, but the device cannot withstand the thrust caused by pressure (test pressure or working pressure).
In addition, the fixing device should be removed immediately after the installation of the universal corrugated compensator. If not removed, the universal corrugated compensator will be in a rigid state. Due to the change of temperature, or the water temperature of the hydraulic test is different from the temperature of the pipe, it will produce corresponding displacement and damage the equipment and its accessories. It should be noted that when the Universal Corrugated Compensator reaches its destination, it must be unloaded carefully to avoid damage. There is no need for immediate installation, do not remove the protective package in a hurry and store the compensator in a dry and clean place. The working conditions of the corrugated compensator are very important for the proper operation of the entire thermal system. In long-term use, erosion from harsh environments or other factors can cause damage to the compensator and lead to failure.
The causes of damage to the universal corrugated compensator throughout the thermal system include three main aspects: first, fatigue or service life, second, compensator corrosion, and third, damage caused by water impact. In the actual operation of the stainless steel universal corrugated compensator, we found that the stainless steel universal corrugated compensator installed in the well or pipe trench is prone to problems, especially because some compensators in the water supply pipeline are prone to damage due to water corrosion. In the process of engineering construction design or pipe design, some problems can be solved and prevented. For example, when installing compensators, they should be avoided side by side as much as possible. If the conditions allow, they should be placed in the wrong position. In addition, corresponding signs should be set at the installation position of the compensator for protection and daily inspection to prevent interference from external factors. Therefore, in order to reduce the failure rate of the compensator of the thermal system and reduce some economic losses, the equipment managers should try to reduce the damage of the above-mentioned factors to the universal corrugated compensator and should not relax the maintenance and inspection of the compensator.
