What a Hydrostatic Pipeline Test Entails
Hydrostatic tests are an essential part of safe pipeline operation. Learn what a hydrostatic pipeline test entails and why it’s important with this guide.
The Purpose of Hydrostatic Testing
No matter what kind of liquids a pipeline carries, it’s important for the equipment to be free of leaks, cracks, and other defects. These pipelines also need to withstand a certain amount of pressure to safely transport their products. Hydrostatic pipeline testing determines whether a pipeline has the strength to withstand its required pressure. It also locates any damage or improper fittings that allow liquid to leak out of the pipe. If a pipeline passes hydrostatic testing, you know it’s in good shape to operate normally.
How a Hydrostatic Pipeline Test Works
Hydrostatic pipeline testing uses water to raise the pressure of a pipeline. To perform the test, workers must isolate the component they’re inspecting and fill it completely with water. This eliminates air within the pipe and pressurizes the system to a stress level above the designed pressure requirements. Workers must then hold the pipeline at that pressure point for a specific amount of time. During that time, the workers will record the pressure, volume, and temperature of the pipeline at regular intervals. This allows workers to determine the precise rates of any pressure drops. Additionally, workers will visually inspect the pipeline for leaks. Some versions of the hydrostatic pipeline test use dyes in the water to make locating cracks and other defects easier.

Warning: All pipe plugs must be blocked or anchored adequately against a force equal to the head pressure times the cross-sectional area of the pipe. Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs. NEVER use an inflatable plug when its failure could cause injury or catastrophic damage or as the only means of protection for personnel working downstream. NEVER use a test pressure greater than the capacity of the weakest pipe or component in the system. Actual conditions vary so user must accept full risk and responsibility for the selection and use of any product. Please review our Warranty, Terms and Conditions.
Note 1: Mechanical and Molded Rubber Plugs are generally used for testing because fabricated Multi-Flex® style plugs may allow some seepage unless customized for a positive seal.
Note 2: We are constantly upgrading our products and while we try to keep the websites up to date it is possible more current specifications may be on a quote or confirming order. Images are typically representative and may not be an exact representation especially of the item size.
