Mechanical Integrity Inspections

Mechanical Integrity Inspections of Ammonia Refrigeration Systems is a specialist service carried out by Alliance across the UK.

While the regulation does not contain specific inspection requirements, industry mechanical integrity guidelines include both periodic visual inspections of equipment and non-destructive testing. Visual inspections are usually conducted by trained plant maintenance personnel and are recommended on an annual basis.

With the ever increasing failure of Ammonia Refrigeration Systems across the UK it is highly recommended that Mechanical Integrity Inspections are carried out by Qualified Inspectors who have experience with API 570 & API 510.

Pressure Vessels (API 510) Inspections

• Hi Pressure Receivers
• Low Pressure Receivers
• Accumulators
• Intercoolers
• Chillers
• Surge Drums
• Transfer Stations

Piping Systems (API 570) Inspections

• Refrigeration Piping
• Valves
• Safety Relief Valves
• Venting Systems

Corrosion Rate/Remaining Life Determination. The corrosion rate of vessels and piping may be determined by one of several methods. Calculation of data collected on vessels in the same or similar service provides a reasonable baseline for life estimates. Vessel life may also be established by experience or published data. Finally, testing the wall thickness of materials after a known period in service and then using an accepted life calculation, as in API 570 for piping or API RP579 for pressure vessels, will provide a reasonable estimate of vessel integrity.
