摘要:Hydrostatic testing is universally known and accepted as a means of demonstrating the fitness of a pressurized component for service. After a test, a pipeline or pressure vessel can be expected to safely contain its intended operating pressure. The confidence level that a pipeline or pressure vessel is fit for safe service increases as the ratio of test pressure to operating pressure increases. This highly beneficial aspect of hydrostatic testing applies not only to a new component to be placed in service for the first time. A similar benefit accrues to an in-service component if that component is taken out of service after a period of time and subjected to a hydrostatic test. A “revalidation” test of the latter type assures either that no significant time dependent deterioration of the component has taken place or that any segment that has been significantly degraded will be revealed and eliminated. There are limitations to the use of hydrostatic testing to revalidate integrity. Some are economic, some are technical, and some are both economic and technical in nature. First, taking a segment of a pipeline out of service means loss of service for the period of the test.
