Mechanical Joint Integrity

Mechanical Joint Integrity (MJI) involves the controlled and verified bolting of pipework, flanges, and other assemblies to eliminate the risk of hydrocarbon and non-hydrocarbon releases during mechanical joint activities. This skill is crucial across craft and technical trades in engineering construction. The ECITB's four-stage model of training and testing enhances MJI competency, which is essential for preventing personal injury and environmental damage. This model is applicable across a wide range of engineering construction industry sectors, including oil and gas and wind turbines. It ensures the safe and effective tightening and bolting of mechanical joints, thereby maintaining structural integrity and minimising leaks.
