ECITB MJI 10/19 eLearning Module –

Hydraulically Torque Bolted Connection Techniques

Duration: 110 mins

Level: Intermediate

Pass mark: 80%

Course Description

Who is the course for?
This course is aimed at workers requiring refresher training before taking the ECITB technical test for ECITB standard MJI10: Hand Torque Bolted Connection Techniques 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 standard but it will prepare you for the technical test.

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 both hand and hydraulic torque tightening.

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 hydraulic torque equipment and how it should be used.

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 with reference to the ECITB standards MJI10: Hand Torque Bolted Connection Techniques 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%.
