Hydrostatic testing of pressure vessels such as pipes, heat exchangers, storage tanks, and ship voids is an essential method for quality control of parts, after production and during use. This process demonstrates the fitness of the pressurized component for service after production or repair and is very important because such containers can explode if they fail under pressure.
Hydrostatic testing is a well-known industry standard test that involves filling the vessel or pipe system with a liquid, usually water, and pressurizing the vessel to the specified test pressure. Pressure loss would indicate a leak. A dye may be used for visual identification of the leak location. When water is used in these tests, corrosion of the metal during and after testing is a concern. This concern is due to the fact that when metal is in contact with oxygen and water, corrosion tends to start.Request Information
Zerust® AxxaVis™ HST-10 is a water-soluble powder additive that prevents corrosion by deactivating ionic contaminants found in municipal water sources that cause rust and hard water deposits on metals. AxxaVis™ HST-10 additive will prevent corrosion of the metals within the solution, at the water line, and above the water line if the water has been sloshed up during the hydrostatic testing. HST-10 creates an invisible film on the interior of the pipes that provides corrosion protection after the water is drained for storage.
