Ammonia System Inspection

Anhydrous ammonia is used for cooling, freezing and refrigeration on a large scale. Examples of products are meat and poultry, cheese, milk, frozen foods and beverages.

Anhydrous ammonia is a hazardous chemical that can be deadly to humans. The ammonia runs through piping in manufacturing facilities that need refrigeration. The facilities are obligated by government entities to be knowledgeable about this system

Some of the piping will see a fluctuation in temperature. This swing in temperature will create condensation or pipe sweating. The water will get trapped between the pipe and the insulation, causing exterior rust and deterioration. Excessive wall loss can lead to an ammonia escape.

Acuren’s Ammonia System Inspection Services offer a unique and comprehensive results package. Non-invasive to the piping insulation test methods, Corrosion Under Insulation Scanning (CUI) and Computed Radiography (CR) set Acuren apart as a leader in the field of ammonia system integrity testing. The visual results show the customer not only the condition of the pipe inside of the insulation, but also pipe wall thickness dimensions.
