Who is the course for?
This eLearning course is aimed at workers requiring refresher training before taking the ECITB technical tests for ECITB standards MJI10: Hand Torque Bolted Connection Techniques, MJI18: Hydraulically Tensioned Bolted Connections, and MJI19: Hydraulically Torque Bolted Connection Techniques.
Is previous experience required?
It is expected that as a participant in this course, you will have received formal training in working with mechanical joints and that you hold suitable qualifications. Completion of this course does not certify you to the ECITB standards but it will prepare you for the technical tests.
How will the course benefit me?
Incorrectly bolted flanges are one of the main causes of hydrocarbon releases, which can have a serious impact on the environment, operating costs and the safety of personnel. This course will give you an understanding of how mechanical joints work and how to use hand and hydraulic torque tightening and bolt tensioning.
The knowledge gained in this course will help you understand how to dismantle, remove and replace components correctly to minimise the leaks and safety concerns associated with incorrectly bolted flanges. It will give an overview of the different types of torque and tensioning equipment and how each should be used.
The course consists of 7 modules;
• Module 1: Introduction to Mechanical Joint Integrity
• Module 2: Principles of the Equipment and Technology
• Module 3: Methods of Tightening
• Module 4: Torque Tightening Theory
• Module 5: Dismantling and Removing Components
• Module 6: Replacing Components
• Module 7: Hand Torquin
• Module 8: Hydraulic Torquin
• Hydraulic Tensioning
How will the course benefit my company?
By properly making up bolted joints, you contribute to the integrity of the asset, and the safety of your fellow workers and yourself. A reduction in hydrocarbon releases means a reduced environmental impact and reduced losses of revenue.
What standards are referenced in the course?
This course is written in reference to the ECITB standards MJI10: Hand Torque Bolted Connection Techniques, MJI18: Hydraulically Tensioned Bolted Connections, and MJI19: Hydraulically Torque Bolted Connection Techniques. The course has been approved by ECITB as part of the ECITB/Step Change in Safety MJI model.
Is there an assessment?
Once you have completed the course, you will be asked a series of questions to check your knowledge and understanding. These are based on the learning objectives for the course and have a pass mark of 80%.
