Context and Challenges

A food processing plant was experiencing a decline in the efficiency of its bag filters. Fine dust and particles were no longer being filtered effectively, which led to poor air quality and potential health risks for the workers. Standard visual inspections did not identify any visible issues, and the root cause of the problem remained unclear.

Why We Were Called Upon

Bioscan was called in to thoroughly inspect the bag cyclone using our advanced bag filter leak detection technology. This advanced technology allowed us to detect internal defects, such as refracted cracks, in the welds and measure their depth. During the baghouse filter inspection, we identified microcracks and weak areas that were allowing small air leaks, compromising the filtration system’s effectiveness. 

This is How We Completed a Thorough Inspection

To perform industrial bag filter maintenance intervention, our rope access technicians, qualified in both inspection and repair, used ropes to access the complex and hard-to-reach areas of the bag filters, without the need for scaffolding. This bag filter troubleshooting access method allowed for a complete inspection, even in the tightest, most vertical spaces. All work was performed autonomously, with safety measures implemented by our specialist rescue technicians, ensuring the safety of the operators throughout the process. 

Solution We Offered

Repairs were carried out on-site by our specialised welders, following the strict standards of the food industry. After repairs, a re-inspection of the Heat Affected Zone (HAZ) was performed, and a roughness test ensured that the surface finish was below 0.8 μm. This control validated the quality of the repair. 

Outcome

After the intervention, the filtration system was restored to optimal efficiency, and the client was able to resume production in a safe environment that met air quality standards. A detailed report was provided, including before-and-after photos of the repairs, along with a certificate of compliance validating the quality of the work.

Context and Challenges

A food processing company was facing leaks in a 100,000-litre storage tank, which posed a significant risk to the quality of the product. Visual inspections failed to detect the cracks responsible for the leaks. Immediate action was required by the vessel crack test inspection service provider to prevent contamination and minimise downtime. 

Our Task Was to…

Bioscan, a renowned provider of tank inspection services, was tasked with performing a full silo inspection of the tank using our electronic scanning technology, which provides precise detection of both visible and hidden defects. During the silo testing, we identified that the defect causing the leak was the result of a previous silo repair. The scanner revealed that the crack was transverse, meaning it passed through the full thickness of the metal, which made it a critical failure point. 

This is How We Spotted the Defect

The 100kL storage tank inspection was conducted by a silo maintenance team of rope access technicians and welders, who accessed all the necessary areas of the tank safely and efficiently. Using ropes, our silo service technicians reached the difficult-to-access spots, ensuring that all areas were inspected thoroughly. They worked autonomously, supported by our specialist rescue technicians, ensuring safety throughout the process.

Solution We offered

Once the problem area was identified, our specialised storage tank repair experts and welders performed the required repair work to the defective area following food industry standards. After the repair was completed, a re-inspection of the Heat Affected Zone (HAZ) was carried out, followed by a roughness test to ensure that the finish was below 0.8 μm. 

Outcome

After the repairs, the tank was returned to service with no further leaks, and the client has not experienced any more issues since. The entire process was completed in 5 hours, ensuring minimal disruption to operations. A detailed report was provided to the client, including photos before and after the repairs and a certificate of compliance confirming the quality and safety of the repair.

Context and Challenge

A global leader in the dairy industry solicited Bioscan to conduct an audit of their complete tank listing, which is crucial for ensuring product quality and safety. The challenge was to detect and address any defects that could compromise the integrity of the tanks while ensuring compliance with food manufacturing standards, then perform repair works where required.

Solution in Two Phases

Phase 1: Comprehensive Inspection

• Internal Inspection: Inspections using Bioscan’s scanning technology for crack detection and integrity testing.
• External Inspection: Crack test the skirt, double jacket, and feet of the tanks to spot signs of damage and corrosion.

Phase 2: Repairs and Asset Management

• Crack Repair: Repair cracks and polish to food-grade standards.
• Asset Management: Identify any tanks that needed complete replacement due to extensive damage over a 1-to-10-year period depending on severity.

Results

Bioscan’s intervention achieved the following:

• Prevented Production Interruptions: Early detection of defects avoided potential disruptions in the future
• Reduced Costs: Timely tank inspection services avoided premature tank replacements, cutting costs.
• Ensured Compliance: Maintained adherence to food manufacturing standards.

Client Testimonial

“Bioscan demonstrated remarkable flexibility and exemplary professionalism. Thanks to their efforts, our tanks are now in a better condition and we have a clear vision of the costs that we need to invest in future years.” — Project Manager

Conclusion

Bioscan’s vessel crack inspection services enabled this dairy industry leader to improve conditions and extend the use of their tanks while ensuring strict compliance. Contact us to find out how we can achieve this for your facilities.
