What We Treat

Stainless Steel Systems That Require Reliable Protection

Our passivation services are designed for stainless steel equipment that must perform under strict
sanitary, corrosion-resistance, or regulatory requirements. We work with new installations, repairs,
and existing systems that need restoration or validation to maintain performance and compliance.

  • Process piping, manifolds, and sanitary tubing
  • Tanks, vessels, and CIP/SIP systems
  • Fillers, mixers, conveyors, and production lines
  • Heat exchangers and utility stainless components
  • Stainless systems in food, beverage, pharmaceutical, and biotech facilities
  • Equipment pre-startup passivation after fabrication or welding

OUR APPROACH

Engineered Passivation for Critical Stainless Systems

Passivation services demand more than a simple chemical rinse. We follow a structured, documented process
that aligns with your quality and regulatory requirements, combining proper surface preparation, controlled
chemistry, and thorough verification to help protect stainless steel equipment, support sanitation, and
extend asset life.

Assessment & Planning

We begin by reviewing your stainless steel equipment, piping, and process conditions to define the right passivation strategy. This includes identifying materials of construction, weld locations, and previous cleaning or chemical exposure, as well as understanding your quality standards, downtime windows, and any validation or regulatory requirements that apply to your facility.

Cleaning & Surface Preparation

Before passivation, we remove oils, fabrication residues, heat tint, scale, and other contaminants that can interfere with the passive layer. Using approved cleaners and procedures, our team prepares internal surfaces so the passivation chemistry can work effectively and produce a uniform, high quality finish.

Controlled Chemical Passivation

We apply citric or nitric based passivation solutions as appropriate for your system, grade of stainless steel, and internal standards. Time, temperature, and concentration are carefully controlled and recorded, creating the conditions needed to rebuild and enhance the chromium rich oxide layer that protects against corrosion.

Rinse, Verification & Documentation

After thorough rinsing and neutralization, we perform visual checks and can support additional testing when required by your quality program. You receive clear, project specific documentation that outlines the systems treated, methods used, and key parameters, so you have audit ready records for your internal and regulatory needs.
