Paul Industries delivers passivation and derouging services for pharmaceutical manufacturers as a single-source supplier and installer. We design, fabricate, install, passivate, and validate passivation and derouging – restoring the corrosion-resistant passive layer on stainless process systems so they stay product-contact safe and audit-ready – built to the standards your process and your auditors require.
What pharmaceutical manufacturers need from passivation services
Pharmaceutical manufacturing lives and dies by cGMP compliance – FDA 21 CFR Parts 210/211, validated systems, and audit-ready documentation. Whether the process is oral solid dose, sterile injectables, or API synthesis, the utilities behind it (process water, clean steam, sanitary piping, CIP/SIP) have to be designed, installed, and documented to survive an FDA inspection.
For this work, that means cGMP (21 CFR 210/211) compliance, validated IQ/OQ/PQ turnover, USP-monograph water quality, and fully documented, traceable installations – not as an afterthought, but engineered in from the first drawing.
What we deliver
- Citric and nitric acid passivation to ASTM A967 / ASTM A380 on new and existing systems
- Field passivation of installed piping, tanks, and vessels – in place, without teardown
- Rouge identification and derouging for water systems and clean-steam lines
- Before/after testing (ferroxyl, water break, copper sulfate) and full documentation packages
- Restoration of the passive chromium-oxide layer to keep 316L corrosion-resistant and product-contact safe
One accountable partner
Most pharmaceutical projects get split between an equipment supplier and an install contractor – and the validation burden falls in the gap between them. Paul Industries closes that gap by self-performing the whole scope, from supply through documented turnover.

Frequently asked questions
What pharmaceutical requirements do you build to?
Our passivation services work for pharmaceutical manufacturers is built around cGMP (21 CFR 210/211) compliance, validated IQ/OQ/PQ turnover, USP-monograph water quality, and fully documented, traceable installations. Every installation ships with the documentation your quality team needs.
Do you handle validation, or just installation?
Both. We install and then support IQ/OQ/PQ with turnover packages, weld/material traceability, and test records – so the system is not just built, it is provable.
Can you take a project from design through startup?
Yes – that is the point of single-source. Design, fabrication, installation, passivation, and commissioning for your pharmaceutical process, under one accountable partner.
