Mechanical & Process Contractors

Mechanical contractors and process piping contractors are responsible for the installation, modification, and commissioning of stainless steel process systems across industrial facilities. During fabrication, welding, installation, and field adjustments, surfaces can be exposed to heat tint, weld scale, and iron contamination that must be removed to restore corrosion resistance before systems are placed into service.

Pure Source supports contractors working in pharmaceutical, biotechnology, food and beverage, semiconductor, aerospace, energy, and industrial manufacturing facilities. We provide passivation services for process piping, utility piping, tanks, vessels, skid-mounted systems, and related stainless steel infrastructure used in critical process applications.

Our field service capabilities allow us to perform on-site passivation when system removal is not practical. This helps contractors complete work in place during installation, tie-ins, shutdowns, and commissioning activities. We regularly coordinate with project schedules to support startup timelines, inspection requirements, and turnover milestones.

Whether supporting new facility construction, system expansion, retrofit work, or equipment replacement projects, Pure Source provides surface treatment services and documentation needed to help ensure stainless steel systems are clean, corrosion-resistant, and ready for operation.
