Passivation Process Benches/Tank Systems

• You may want to consider passivation of the entire component or equipment surface, or certain areas which experience welding, grinding, machining, polishing, or repair.
• Surface contamination introduced during fabrication or handling may require appropriate cleaning and subsequent passivation.
• Consider the service environment and the potential for corrosion or contamination of the stainless-steel surface.
• Customer specifications and applicable industry standards may define when passivation is required and how the process should be verified.
• For production applications, passivation frequency should be established according to the material, manufacturing process, service conditions, and maintenance requirements.

Types of Passivation Equipment We Offer

HPI provides passivation equipment in a variety of configurations based on part size, production volume, process chemistry, material handling, and facility requirements.

Our equipment can incorporate filtration and solution circulation, heating, ultrasonic cleaning, conductivity monitoring, rinse systems, and forced-air drying where required by the application.

• Bench-top Ultrasonic: We offer these ultrasonic passivation systems with tanks in various sizes. A typical configuration can include a parts washer or cleaner, passivation tank, filtration and circulation, rinse tank, and parts dryer. Ultrasonic cleaning can be incorporated as a cleaning stage to assist in removing oils, machining residues, particles, and other contaminants from complex component geometries.
• Wet Bench: We offer wet bench passivation systems which are reasonably big units or even like cabinets. They are multipurpose benches, wherein multiple functions can be performed, such as passivation, washing, drying, rinsing, and so on.
• Ultrasonic Automated: We offer automated passivation systems to industries which require repeatable processing and reduced operator intervention. Depending on the system configuration, automation can include process sequencing, controlled immersion times, rinse management, filtration, conductivity monitoring, drying, material handling, and safety controls.
• Agitated Immersion Multi-Tank: Our multi-tank immersion passivation equipment can combine cleaning, rinsing, chemical passivation, and drying into a controlled process sequence. Depending on the application, systems can incorporate alkaline or aqueous cleaning, oil and contaminant removal, chemical passivation, multiple rinse stages, filtration, circulation, agitation, and forced-air drying.

These systems are suitable for complex components and assemblies requiring controlled cleaning and chemical surface treatment.

Stainless Steel Passivation Lines

HPI provides stainless steel passivation lines ranging from compact bench-top systems to customized production installations.

A complete line can integrate cleaning, chemical passivation, rinsing, filtration, solution circulation, drying, material handling, and process controls into a coordinated production system.

Key Advantages:

• Consistent and repeatable processing
• Reduced labor costs
• Integrated filtration and circulation
• Conductivity monitoring options
• Forced-air drying
• Process documentation and traceability options
• Modular system configurations
• Customized tank sizes and layouts

HPI can design passivation process tank systems around your production volume, component geometry, chemistry, process sequence, and facility requirements.

Passivation Equipment for Manufacturing

HPI provides passivation equipment for manufacturing applications where controlled surface treatment, cleanliness, corrosion resistance, and repeatable processing are important.

Our systems can be configured for:

• Aerospace components
• Medical device components
• Precision-machined stainless-steel parts
• Pharmaceutical and bioprocess equipment
• Industrial components
• Stainless steel assemblies
• Fabricated components

For aerospace applications, systems can be designed around customer-specified processes and applicable requirements.

Equipment can also be designed to support applicable ASTM A380/A380M processes. Actual process compliance depends on the specified material, chemistry, operating parameters, testing, acceptance criteria, and customer requirements.

Applications of Passivation Equipment

Here are some application areas of our passivation equipment.

• Cleaning, rinsing, and passivation are commonly integrated into a complete stainless-steel surface-treatment process. These operations can be combined using the appropriate passivation line and automated systems.
• These machines on their own or when equipped with other systems such as pump filter systems, heaters, and so on offer additional features such as a hot cleaning solution, hot air drying, water-based rinsing of stainless-steel equipment surfaces, and more.
• While passivation is different from electropolishing, we do offer equipment for the latter. Electropolishing is an electrochemical metal-removal process that can improve surface smoothness and cleanliness and may also result in a passivated stainless-steel surface. The appropriate process depends on the required surface finish, material, dimensional requirements, cleanliness requirements, and applicable specification.
