Unlike many competitors, our chrome plating process is strictly controlled to prevent foreign body defects through clean environments, advanced filtration, and multiple inspections. The result is a flawless, hygienic finish with no debris or imperfections—just consistent, long-lasting performance.

Beyond Repair – Tube Replacement Required

The photos above show real examples of heat exchanger tubes in varying conditions—from early signs of wear to tubes that are beyond repair. Recognizing these stages is key to avoiding unexpected downtime and costly replacements. If your tubes are showing pitting, scoring, or chrome loss, scheduling repairs early can save both time and money. For severely damaged tubes, replacement may be the safest and most efficient option.

Here’s what sets us apart—below are real examples of the defects you might find in competitor chrome plating, but never in ours.

Restoring Performance: The Refurbishment and Re-Chroming Process for Heat Exchanger Tubes

In food and dairy processing, uptime and product consistency are non-negotiable. When it comes to scraped surface heat exchangers (SSHE), properly maintained heat exchanger tubes are critical to efficient operation and sanitary performance. Refurbishing and re-chroming these tubes not only extends their service life but helps prevent contamination risks and unexpected production stops.

The process begins with a full inspection of the tube’s exterior and flanges. Any signs of wear, dents, or corrosion are flagged, and repair recommendations are made based on operational impact. The interior of the tube is also closely inspected to assess severity of chipped chrome, pitting, or damage that could affect product flow or cleanability.

At your request we will give special attention to o-ring grooves and seal areas, which will be restored as needed to ensure proper sealing under pressure. All machining details—including flanges, threads and locking lugs will be checked for accuracy to maintain proper integration with the rest of the SSHE system.

Once these inspections are complete, the existing chrome plating is carefully stripped to expose the base metal. The tube’s interior diameter is then honed and buffed, removing imperfections and preparing the surface for plating. A second inspection follows, checking for any remaining grooves or galling that could impact performance.

The tube is then re-chromed to a thickness of 0.004-0.006 inches per wall. This hard chrome layer enhances durability and resists wear under continuous use. A post-plating hone brings the interior to a high-gloss finish—important not only for product flow but for maintaining hygienic surfaces in food-contact environments.

Finally, the entire tube undergoes a third and final inspection to confirm it meets or exceeds all original equipment manufacturer (OEM) specifications. Only then is it cleared for reintegration into your production line.

For food processors, this comprehensive process ensures more than just restored equipment—it delivers reliable operation, better product integrity, and minimized downtime. Investing in expert refurbishment and re-chroming helps keep your line running clean, efficient, and compliant.
