Heat exchanger crack integrity testing and pasteuriser inspection

Food, dairy and beverage industry

Within the food, brewing, drink and pharmaceutical industries there is an ever-present risk of product contamination that, if undetected, could result in product recalls, damage to brand names and, in the worst case, serious illness or death.

Independent Integrity Inspection Limited (INDEi) as a supplier of non-destructive testing and integrity inspection services can form a crucial part of any “Hazard Analysis and Critical Control Points (HACCP)” programme for the thorough and definitive testing of pasteurisers and heat exchangers.

Our methods:

Saline conductivity testing method

INDEi has developed a testing method that utilises the pressurised conductivity differential system, which ensures the detection of any through-thickness cracks and proves the integrity of plate and tubular gaskets in heat exchangers pasteurisers.

Inspection and examination of materials, components, and assemblies

Using clean potable water on one side and inert sodium sulphate as the corresponding medium and combined with differential pressures, the ability to detect cross-contamination is possible and highly effective.

The saline conductivity method is dynamic, simulation of real-time running conditions within a heat exchanger.

Helium Gas tracer method

Helium is the ideal choice of tracer gas to find leaks for several reasons. It is non-toxic, inert, non-condensable, non-flammable and not normally present in the atmosphere at more than trace amounts (5 ppm). Due to its small atomic size, helium passes easily through cracks and leaks.

Due to its small atomic size, helium passes easily through cracks and leaks. The only molecule smaller than Helium is Hydrogen which is not inert.

A helium leak detector, also known as a Mass Spectrometer Leak Detector (MSLD), is used to locate any through-thickness cracks in heat exchangers and pasteurisers. The tracer gas, helium, is introduced to one side of the heat exchanger/pasteuriser and the other side is connected to the leak detector. The helium leaking through the crack entered through the system and displayed on a meter.

Regular heat exchanger and pasteuriser testing help ensure early detection of a crucial problem before it becomes apparent as a health risk.

The integrity testing of plate, tubular, scraped-surface pasteurisers and heat exchangers to detect cross-contamination has become a critical element of a leading producers’ preventative maintenance programme.

In addition to the integrity/crack testing, the exact location of the defective plate(s) or tubular section within the heat exchanger or pasteuriser can be achieved by a supplementary testing method utilising our ultrasonic acoustic equipment enabling the testing engineer to identify the individual component within the suspect section.

We support you in determining the best solution for cost-efficiently maintaining production, quality and regulatory requirements.

We are the one source for all of the inspection methods needed to meet your specific requirements for accurate and reliable results.

Our methods of integrity testing is efficient, cost-effective and provides a very quick solution.

If you require plate, tubular or scraped heat exchanger testing or pasteuriser inspection, please contact us today for quality service and competitive pricing.

The integrity test is carried out in-situ and does not require the heat exchanger/pasteuriser to be disassembled;
Any residual water or other liquids remaining in the plant does not hinder our testing methods;
The chemical solution is non-toxic and non-corrosive and quickly removed by CIP;
Minimal disruption/downtime to production;
A typical heat exchanger/pasteuriser can be tested within an hour;
3µm particle system filtration allows accurate defect detection;
No false alarm or other spurious readings;
Far superior to the hydrostatic test method which is only suitable for the detection of gross defects and certainly not suitable for fine cracks or other through-thickness imperfections in large plate heat exchangers;
Gaskets condition examined as part of the overall test;
Exact plate location
