Automated Pipe Cleaning and Acid Passivation System

Pipes and tubes often are difficult cleaning and passivation applications because various washing, rinsing, and passivation solutions must be flushed through the pipes. Pipe flushing applications with tight aspect ratio (high length vs. the internal diameter) or multiple bends tend to require forced or pumped circulation through the tubing.

Passivation Process Flow Diagram

Building on the principal of our automated passivation system which moves the various solutions from storage tanks to a central process tank rather than moving the parts from tank to tank

Pipe Flushing Manifold Port for Cleaning and Passivating

pipe-cleaning-passivating-flushing-manifold-port

This automated pipe cleaning and passivation system accommodates a manifold for connecting pipes and tubing. This manifold not only allows for the cleaning, rinsing, and passivation solutions to be pumped through the pipes but also for compressed air to force any remaining solution out of the tubes ensuring minimal dragout between process steps as well as drying of the internal diameter after all process steps are complete.  Since the industrial parts cleaning system forces solution through the pipes, the system is able to handle complex bends in the tubing conventional pipe cleaning systems can not handle.

Automated Nitric Passivation System for Pipe Cleaning and Passivation

automated-pipe-cleaning-passivation-system

This nitric passivation pipe cleaning system is able to clean, rinse, passivation, rinse, final rinse and dry pipes and tubes.  The automated equipment is able to monitor and maintain DI (deionized) rinse water to ensure part exterior and pipe interior are rinsed thoroughly ensuring a clean, passivated, spot free pipe inside and out.

Other Tube Cleaning Applications

For simple straight pipes requiring cleaning, our crossflow tube cleaning equipment offers simple pipe flushing action by creating a lateral solution flow across the tank depth.  For really small ID, our cannula/needle cleaning system or automated guidewire/catheter cleaning and passivation system is recommended with ultrasonics.

Pipe / Tube Washing Equipement

Applications:

  • Drawn tubing with oil used during drawing / extrusion
  • Hydroformed pipes
  • Electrical conduit
  • Aerospace and automotive fuel delivery systems
  • Medical device catheter and tube flushing equipment

Semi-Automated Inline Citric Passivation Solution with Data Tracking

For one medical device manufacturer, the design of a citric passivation solution faced two major challenges: The manufacturing process required performing a water-break test after cleaning parts, before proceeding to passivation. This meant that they could not use a fully automated passivation solution. The system had to have data tracking for quality control purposes. Semi-Automated […]
