Pipeline Hydrostatic Test

Ergil Group is known the market leader in the field of hydrostatic test, cleaning, drying, coating, and protection of natural gas and oil pipeline, in Turkey. For years, Ergil Group successfully completed many projects in the toughest conditions.

What is the Pipeline Hydrostatic Test?
Before the pipeline is put into natural gas service, the entire length of the pipeline is pressure tested using water. The hydrostatic test is the final construction quality assurance test. Depending on the varying elevation of the terrain along the pipeline and the location of available water sources, the pipeline may be divided into sections to facilitate the test.
Each section is filled with water and pressured up to a level higher than the maximum operating pressure. The test pressure is held for a specific period of time to determine if it meets the design strength requirements and if any leaks are present. Once a test section successfully passes the hydrostatic test, water is emptied from the pipeline in accordance with state and federal requirements. The pipeline is then dried to assure it has no water in it before gas is put into the pipeline.
