Here at Global we will provide our customers with professional technicians to perform a hydrostatic test. We will furnish all equipment necessary to pre-clean, fill, pig, test and dewater the pipeline. We will also provide the compressors, dryers and pigs to dewater and dry the line.  We will also furnish the launchers and receivers’ necessary, the reports and PE certifications for the hydrotests.  In the instance of a leak happening during a hydrotest, our technicians are trained to recognize, locate, and take appropriate action. We have experience in the proper sourcing of water prior to the test, and the proper disposal following the test.

Hydrostatic testing is used to determine and verify pipeline integrity. Pipelines are designed to operate at a certain maximum allowable operating pressure (MAOP). Pipelines must be hydrostatically tested to ensure that it is structurally sound and can withstand the internal pressure before being put into service.

Pipelines are hydrotested by filling the test section of pipe with water and pumping the pressure up to 125% to 150% greater than the maximum allowable operating pressure (MAOP) and holding the pressure for a period of four (4) to eight (8) hours.
