A Brief Analysis of the Application of Compensators in the Petroleum and Petrochemical Industry

2021-03-22
In the pipeline design of petrochemical plants, it is often necessary to account for high-temperature and high-pressure operating conditions. Therefore, during the design phase, thermal expansion effects in pipelines must be taken into consideration. As a general rule, priority should be given to utilizing the inherent flexibility of the pipeline’s own structure to absorb thermal displacements. However, when process operation conditions or equipment layout constraints limit the pipeline system’s natural flexibility, compensating devices can be employed to absorb thermal displacements. Among these compensating devices, rotary compensators stand out due to their strong compensation capability.

Managing changes in pressure drop can reduce the operating costs of process equipment, while alterations in thermal expansion stresses significantly enhance the operational safety of the piping system itself. Therefore, these advantages are particularly relevant in the design of long-distance petrochemical pipelines.
