Maintain Safety Standards and Durability of Your Vessel Over Time
In order to provide comprehensive pre-commissioning services to its customers, B&W performs Hydrostatic Testing services to verify the integrity of piping systems, vessels, boilers and HRSGs. Lines and vessels are tested to the accepted ANSI code depending on the type of facility they are installed in. The applicable code is B31.3 for chemical plants and refineries, and B31.1 for power plants. For boilers and HRSGs, the test must conform to boiler codes applicable in the state where the boiler/HRSG is located.
A hydrostatic test is performed to ensure the structural integrity of the vessel or piping system is secure for testing and operation. The test involves filling the vessel or system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing and recording whether there is a pressure loss. The location of a leak can be visually identified more easily if the water contains a colorant.
Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then re-qualified at regular intervals using the proof pressure test, which is also called the modified hydrostatic test.
Because hydrotesting is a mandatory prerequisite that must take place before projects can move from construction to pre-commissioning and commissioning, B&W is well positioned to integrate these activities to prevent costly rework. For example, it is common for many projects to perform certain construction activities more than once, like removing control valves, flow elements and other sensitive components for hydrotesting, then again for cleaning, to ensure these components are not damaged during testing or cleaning. This often happens when two activities are handled by different subcontractors.
By using a single source, B&W can design an integrated hydrotesting and cleaning program that ensures these construction activities only happen once, which eliminates many wasted man-hours and unnecessary costs.
These tests must be performed by qualified and trained personnel to avoid safety and environmental incidents. B&W employs highly trained and qualified personnel to ensure hydrotests are performed safely and effectively. In addition, our hydrotests are accompanied by comprehensive engineering procedures to ensure all safety protocols are followed and the correct equipment is provided to execute the work.
