For over 50 years, Astro Pak has been perfecting the chemistry and cleaning process of Passivation. Our proprietary chemistry, UltraPass® is a chemical treatment for stainless steel and other metals that enhances the ability of the treated surfaces to resist corrosion. This passive layer, which is sometimes called the passive film, is responsible for providing corrosion resistance at the surface of the metal. It is a very thin layer of highly stable metal atoms that do not easily corrode or rust. The illustration below shows the very thin passive layer at the outer surface of the metal:
We provide expertise in delivering chemical cleaning services to installed systems: pre-operational, pre-commissioning of new construction, post modification, or for maintenance and shut-downs. We also offer passivation with nitric acid and other chemicals when needed. In addition, Astro Pak can process piping, fittings, vessels or other types of equipment in one of our shops located nationwide.
Astro Pak routinely responds to emergency outages for critical utilities, systems and equipment. When our job is completed, you will receive cGMP documentation packages for your systems and equipment maintenance records.
