Hydrostatic testing of pressure vessels, such as pipes, heat exchangers, storage tanks, and ship voids, is essential for verifying the integrity of these components post-production and during use. This process demonstrates that the equipment can handle operational pressures safely, identifying any potential weak points needing repair. The procedure typically involves raising the internal pressure above the standard operating pressure to detect leaks or structural flaws.
However, using water in hydrostatic testing introduces the risk of hydrostatic corrosion. When metal surfaces are exposed to water and oxygen, corrosion can begin quickly. ZERUST® offers advanced corrosion solutions for hydrostatic testing, protecting metals from rust and scaling during and after testing. With ZERUST® products, companies can mitigate corrosion risks effectively, ensuring the durability and longevity of their assets.
ZERUST® Corrosion Solutions for Hydrostatic Testing
ZERUST® AxxaVis™ HST-10
ZERUST® AxxaVis™ HST-10 is a water-soluble hydrostatic testing corrosion Inhibitor that neutralizes ionic contaminants in water, such as chlorides found in municipal sources, that cause rust and hard water deposits on metals. This powder additive protects the interior surfaces of pressure vessels during testing, including areas above the waterline where sloshing may occur, by forming an invisible film that continues to inhibit corrosion after the water is drained. Suitable for ferrous metals only, AxxaVis™ HST-10 hydrostatic testing additive can be used with ZERUST® Axxatec™ HST-M100 for systems containing aluminum, copper, or brass, providing a versatile solution for multimetal environments.
AxxaVis™ HST-10 is environmentally safe and reusable in some applications, reducing handling and disposal concerns and meeting stringent environmental standards, including TSCA, RoHS, and REACH compliance.
ZERUST® Axxatec™ HST-M100
For a broader range of metal compatibility, ZERUST® Axxatec™ HST-M100 is a premium hydrostatic fluid additive designed to protect ferrous metals, aluminum, copper, and brass. This water-soluble, low-foam additive provides a dry-to-touch finish that continues to prevent corrosion even after testing is complete. Axxatec™ HST-M100 effectively deactivates ionic contaminants that lead to rust, ensuring the reliability of pressure vessels like pipes, storage tanks, and heat exchangers.
Ideal for applications requiring multi-metal protection, Axxatec™ HST-M100 complies with global standards, offering a safe and non-flammable solution that aligns with environmental guidelines. Its versatile formulation can be diluted to meet specific testing needs, making it the optimal choice when testing various metal alloys.
ZERUST® Axxatec™ HST-20L
ZERUST® Axxatec™ HST-20L is an effective water treatment concentrate tailored specifically for hydrostatic testing ferrous metals. It prevents rust and scaling by deactivating ionic contaminants in water, making it ideal for large components such as pipes and storage tanks. Axxatec™ HST-20L offers strong corrosion protection during and after testing, ensuring that metal surfaces remain rust-free.
Designed for use with ferrous metals only, Axxatec™ HST-20L may be combined with ZERUST® Axxatec™ HST-M100 when testing involves aluminum, copper, or brass. This non-flammable, solvent-free concentrate complies with TSCA, RoHS, and REACH requirements, making it safe for regulated discharge and reusable in certain applications, further reducing environmental impact.
