Electropolishing creates a smooth and clean surface that enhances corrosion resistance and reduces particle entrapment in microscopic crevices. With our innovative and proprietary process, Cardinal Systems greatly increases the ability to deliver quality electropolished components for dependable performance in any critical system.

Cardinal’s electropolishing creates a leveling action so effective that a finished surface often has only one tenth the surface area of a mechanically or chemically polished part. The electropolished part will have improved corrosion resistance and appearance.

Nitric acid passivation provides improved corrosion resistance, even if the part is not electropolished. We control pH, temperature, flow, suspended contaminants, and time in our passivation process to maximize the effectiveness of the passivated finished part. We can effectively passivate a wide variety of products including long lengths of coiled tubing.

Cardinal Systems offers a range of services including cleaning for oxygen service and specialized cleaning to customer specifications requiring solvent and heated deionized water processing.

With the capability to work with most metals, Cardinal’s experienced craftsmen and engineers can design and fabricate components to your specifications such as special fittings, gas manifolds, containment systems, pipe-to-tubing transitions, and cut-to-length tubing.

Mechanical Polishing
Mechanical polishing uses abrasive materials to deburr and reduce surface irregularities. This can be done to inside and outside surfaces. Passivating after fabrication and mechanical polishing restores the passive layer of the original base material.

Clean Room Packaging
In addition to providing cleaning services we also provide packaging services such as kitting, capping, bagging, double bagging and sealing in our 2500 ft2 Class 10 (ISO Class 4) clean room environment.
