API RP 1193 – Pipeline Pressure Cycle Management

It provides recommended practices for pipeline pressure cycle management (PCM). It helps operators manage the effects of internal pressure fluctuations on hazardous liquid and natural gas pipeline systems and can also be applied to any pressure-retaining system exposed to cyclic operating pressures.

The standard provides guidance for collecting, analyzing, and interpreting pressure cycle data to develop, implement, and maintain an effective Pressure Cycle Management (PCM) program. It also describes methods for assessing operational pressure cycling and its potential impact on pipeline integrity.

This outlines preventive measures to reduce the risks associated with cyclic pressure loading in pipelines, piping, fittings, and pressure vessels. It also includes guidance on in-service pressure monitoring, operational response, and ongoing management of pressure cycling to support safe and reliable pipeline operation.
