Product Description

Product Description

Axxatec™ HST-20L water treatment concentrate is a highly effective way to protect the interior surfaces of pressure vessels from corrosion that can rapidly form during and after hydrostatic testing. Add the water treatment concentrate product to water to make it suitable for hydrostatic pressure test processes conducted on pressure vessels such as pipes, heat exchangers, ship voids, and more. Designed for use on ferrous metals only, it is not compatible with aluminum. Use Axxatec™ HST-20L with ZERUST®/EXCOR® Axxatec™ HST-M100 additive for applications involving aluminum, copper, brass, or other metal alloys containing red/yellow alloys.

Used Axxatec™ HST-20L water treatment concentrate product can be analyzed for quality and, in some cases, reused. Additionally, spent Axxatec™ HST-20L working fluid may be discharged into the soil or marine environments (subject to normal legislative restrictions). Furthermore, Axxatec™ HST-20L water treatment concentrate does not contain solvent, is non-flammable, compliant with Global Automotive Declarable Substance, TSCA, ECHA SVHC, RoHS, and REACH requirements,  offering a globally compliant solution for hydrostatic corrosion prevention.
