What are the requirements of a Mechanical Integrity program?
Mechanical Integrity (MI) is significant in terms of the asset coverage involved. System examples include fixed equipment such as pressure vessels and storage tanks, piping systems and associated hardware (valves, fittings, etc.), relief devices, vent hardware, emergency shutdown/control systems. In many cases, this means that all equipment within the boundaries of a facility is subject to the PSM – Mechanical Integrity standard.
MI encompasses the activities necessary to ensure that equipment/assets are designed, fabricated, installed, operated and maintained to a desired performance in a safe, environmentally protected and reliable fashion. MI is a sub-set of an effective reliability program and overall asset management.
Let’s take a look at the MI requirements: –
Mechanical integrity (MI) of equipment has been controlled at all industrial facilities for many decades. Everything wears out eventually. With MI, it can help determine when that “eventually” might be (the operational life expectancy).
