However there is a serious message – and that message is; There are two ways to do anything; the ‘RIGHT way’ or the ‘WRONG way’.
I remember as an engineering apprentice, I was introduced to a wealth of information from day one, covering topics like safety procedures and protocols as well as technical information and engineering best practice.
This knowledge is crucial in helping develop the ‘hands on’ skills and competencies needed to excel in your chosen craft. And it should stay with you for life.
For example, consider the correct use of tools (see image);
🔘 Item #1
A micrometer (or micrometer screw gauge) is a precision measuring instrument used to measure small distances or thicknesses with great accuracy. It consists of a calibrated screw mechanism that allows for fine
adjustments and measurements.
It IS a calibrated precision tool and should NOT be used as a G-Clamp!!
🔘 Item #2
A slogging/flogging spanner, also known as a hammer wrench or hammer spanner, is a heavy-duty tool designed to loosen or tighten bolts and fasteners, often in industrial settings.
It is NOT a precision tool and should NOT be used for making bolted flanged connections because (believe it or not) it isn’t calibrated and the torque output is NOT measurable!!
All this may seem rather petty and obvious but this week our flange inspection teams have witnessed a significant amount of flanges that were overtightened with flogging spanners that resulted in damaged PTFE type gaskets (upper tier COMAH chemical plant).
Using these types of spanners on bolted joints poses a significant risk because the torque applied is not measurable. This can lead to two potential problems:
❌ Over-torqueing: Applying too much force can damage the gasket, deform the bolt, or even strip the threads, leading to a compromised joint.
❌ Under-torqueing: Applying too little force can result in a loose joint, which may cause leaks or even lead to the joint coming apart under pressure.
For bolted joints where precise torque application is crucial in hazardous industries, such as those involving gaskets, it’s always best to use a torque wrench. A calibrated torque wrench allows you to measure and apply the exact amount of torque specified for the joint, ensuring a secure and reliable connection.
We demonstrate this at our Centre of Excellence during all our industry approved joint integrity training courses. Book a course, come along – get involved.
and ALWAYS do the ‘RIGHT’ thing ✅
