On-Site & Shop Passivation Services

Astro Pak has over 60 years of experience perfecting our passivation chemistries and processes.  We bring that expertise, along with our state-of-the-art equipment and highly trained personnel, on-site to your facility to perform preoperational or maintenance cleaning and passivation on your systems and equipment.

For components, parts, and sub-systems that can be serviced out-of-place, Astro Pak’s nationwide shop facilities are well suited to affordably meet your cleaning requirements.  We have state-of-the-art facilities that can accommodate parts of all sizes and volumes, including dip tanks up to 40ft and overhead bridge cranes with 7.5-ton lifting capacity for oversized parts. Additionally, we offer pick-up and delivery services as well as cGMP compliant documentation packages at the end of each job.  Our highly skilled technicians and controlled environments ensure consistent quality and compliance to industry and customer-specific standards.

Our Passivation Standards

Astro Pak prides itself on a long legacy of meeting and exceeding the standards set forth by a variety of organizations in numerous industries, including ASTM, ASME, SAE, SEMI and FDA, to name a few.

Trust the Experts in Passivation

Astro Pak has been perfecting its passivation chemistries and processes for over 60 years. Our proprietary Ultra Pass® passivation process is renowned for its environmentally friendly blend of high-purity ingredients, including chelants that bind with metal ions rendering them incapable of redepositing on surfaces.  As a result, the material handling requirements and other impacts on-site are greatly reduced.

Beyond that, the Ultra Pass® passivation process provides superior results, capable of producing an optimized passive layer on the surface of stainless steels, yielding unmatched corrosion resistance. Our studies have shown that the chrome to iron ratios achieved by Ultra Pass® passivation far exceeds ASME BPE recommended minimums and meets or exceeds the requirements of many industries including semiconductor, aerospace, pharmaceutical, and biotechnology.
