MJI18 – Hydraulically Tension Bolted Connections

MJI18 – Hydraulically Tension Bolted Connection Techniques

This course covers specifications, methods, processes, techniques and procedures for using hydraulic tensioning equipment. It will explain how to remove components from hydraulic tensioning bolted connection systems, how to replace, reassemble securely and verify the integrity of assembled joints. The course is assessed through written tests, practical observations and exercises. Successful completion results in an ECITB MJI18 certificate, valid for 12 months. Within 12 months work based task assignments need to be completed and technical competence validation test TMJI 18 taken.
