Case Study

Context

Twenty years of continuous operation is a long time to ask any piece of equipment to perform without accumulated wear. A beverage manufacturer had been running several ageing stainless-steel storage tanks well beyond their initial design horizon, and while no active failures had occurred, the decision to increase production demand prompted a closer look at what those years of cyclic loading had quietly left behind.

The client was not responding to a crisis. They were getting ahead of one.

Challenges

Bioscan was brought in to assess the true condition of the tank fleet before production pressure increased. The inspection covered tank walls, nozzle connections, base welds, structural support transitions, and all product-contact surfaces. The challenge was that the tanks had shown no external signs of distress, meaning any defects present would likely be internal, gradual, and non-visible without specialist detection methods.

The Bioscan Response

Our silo tank crack testing across the full asset range uncovered early-stage fatigue cracking, weld degradation around nozzle areas, localised stress concentration points, and minor corrosion-related surface deterioration. Several of these defects had developed gradually over years of cyclic loading and were entirely invisible from the outside.

As a specialist industrial inspection company, we understand that assets approaching or exceeding their design life carry a different risk profile than newer equipment. An industrial silo crack test at this stage is not a precaution. It is a necessary part of responsible asset management.

Targeted weld repairs, reinforcement modifications, grinding, and polishing were completed across all affected areas. We also provided preventative recommendations for ongoing monitoring, giving the client a structured basis for tracking asset condition as production demands grew.

Outcome

They were able to extend the lifespan of the storage tanks, saved themselves the time and expenses of any emergency repairs, and walked away from the situation with a much better idea of how healthy their assets were compared to before. They had a better long-term maintenance strategy going forward.

Impact

Preventive equipment maintenance rarely makes headlines, but it consistently delivers better outcomes than reactive repair. This case is a straightforward example of what happens when a manufacturer chooses to understand their assets before they fail rather than after. Bioscan’s tank inspection service gave this client the visibility they needed to make confident, informed decisions about their production future.

Context

Every year, this dairy manufacturer entered their annual shutdown with the same setup: one contractor for inspection and another for welding repairs. And every year, the same problems followed. Repair decisions got delayed while findings were communicated across teams. Confined spaces were entered multiple times. Downtime stretched beyond what the production schedule could comfortably absorb.

The inefficiency was not a technical failure. It was a coordination one.

Challenges

Bioscan was brought in to consolidate the entire process under one team. The scope included a full dairy plant equipment inspection, crack detection across all critical components, on-site repairs, grinding, and hygienic polishing, all within a single shutdown window. No handovers, no waiting, no duplication of access. The pressure was not just technical. Every hour of additional downtime had a direct cost to production output.

The Bioscan Response

Our industrial spray dryer crack test identified multiple cracks across dryer cones, cyclone transitions, fluid bed welds, and internal ducting. In a fragmented setup, these findings would have triggered a separate mobilisation for repairs. With our integrated team, the same people moved directly from detection to correction.

Food-grade welding, polishing, and verification were completed in sequence without requiring repeat confined-space entry. Our spray dryer inspection process was built to keep the shutdown moving rather than create decision points that stall it. Dairy processing equipment repairs were carried out to full hygienic finish standards, with a final verification pass completed before sign-off.

Outcome

Total shutdown duration came down. Contractor coordination ceased to be a variable. The manufacturer restarted production faster and with a clearer picture of asset condition than any previous shutdown had delivered.

Impact

Most shutdown overruns are not caused by the complexity of the work. They are caused by the gaps between the people doing it. Bioscan’s integrated model removes those gaps entirely, compressing timelines without cutting corners on quality or safety.

If your next planned shutdown is still being built around separate inspection and industrial equipment inspection contractors, there is a more efficient way to approach it. Talk to Bioscan about what an integrated programme could look like for your facility.

Context

A food ingredient manufacturer had been reporting unexplained product staining and occasional contamination concerns within their bag filter system. Routine cleaning cycles and visual inspections had repeatedly failed to identify the source of the problem, leaving the quality team without a clear answer and the issue continuing to affect production.

The contamination risk was not only a product quality concern. It pointed to a deeper structural issue within the equipment that standard inspection methods were simply not equipped to uncover.

Challenges

We were contracted to carry out a thorough bag filter system inspection covering internal bag filter housings, product-contact welds, duct transitions, and powder accumulation zones. The main issue was finding defects hidden by compacted powder deposits. These defects had been missed during previous cleanings and visual checks.

The Bioscan Response

Bioscan mobilised a team to conduct a detailed internal inspection of the bag filter system. Our baghouse filter testing revealed hidden corrosion beneath compacted powder deposits, surface degradation in moisture-prone areas, and localised pitting and cracking across multiple product-contact zones. These were not surface-level issues. The affected areas had created ideal conditions for product retention, bacterial harbourage, and cleaning shadow zones that routine methods could not reach or detect.

As a specialist industrial inspection company, we understand that what is visible during routine checks rarely tells the full story, particularly in powder-handling systems where build-up can conceal significant structural and hygienic risk over time.

After finding issues, we removed damaged materials, fixed the stainless steel parts, and polished the surfaces that touch the product. Once we finished, we did a baghouse integrity test to make sure everything met the hygiene standards. The system then went back online, good as new.

Outcome

After our inspection, we took out all the worn-out materials and fixed the damaged stainless steel parts, then polished the product contact surfaces. We ran a baghouse integrity test afterwards to ensure everything met the needed standards before putting the system back into use.

Impact

This case shows that food processing problems often stem from issues that visual checks can’t catch. Bioscan’s bag filter inspection helped the manufacturer fix a longstanding problem by giving them clear insights. They were able to take corrective actions, improving their hygiene in the long run.
