Mechanical Integrity Program requirements

Spring pipe hangers is required must be regularly inspected in a mechanical integrity program. 

ISA 84.01/IEC 61511 uses an order of magnitude metric, the SIL, to establish the necessary performance. A hazard and risk analysis is used to identify the required safety functions and risk reduction for specified hazardous events. Safety functions allocated to the SIS are SIFs the allocated risk reduction is related to the SIL. The design and operating basis is developed to ensure that the SIS meets the required SIL. Field data are collected through operational and mechanical integrity program activities to assess actual SIS performance. When the required performance is not met, action shordd be taken to close the gap, ensuring safe and reliable operation. 

You might ask, What would the PSM regulation require A portable sandblast rig would normally not be included in the covered process within a refinery or chemical plant. But, a facility that had such PSM programs would probably have influences in the Mechanical Integrity area that encourages strict adherence to welding procedures and emphasizes use of original manufacturers methods and standards. 

This topic, the full name of which is Assurance of Quality and Mechanical Integrity of Critical Equipment, requires that procedures have to be in place and implemented so that critical equipment is designed, fabricated, installed, tested, inspected, monitored, and maintained in a manner consistent with appropriate service requirements, manufacturer s recommendations, or industry standards. Contractors should have programs in place to address the safety of their own critical equipment.
