Do you need Hydrotesting of Pipeline solution? Choose us as your partner and we will provide you with a solution that will satisfy you.

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.  Hydrostatic testing consists of raising the pressure level above the operating pressure to locate any defects in need of repair.

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. However, when ZERUST® AxxaVis™ HST-10 is added to water, it will prevent corrosion during testing, wet storage, and after testing.

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.

After use, ZERUST® AxxaVis™ HST-10 can be analyzed for quality and, in some cases, reused. It’s also designed to be safe and environmentally friendly, having passed soil spike tests (EPA Method 1644) showing no observable effect concentration (NOEC), reducing handling and disposal concerns. *
