Fitting pipework systems to mechanical assemblies

​

This standard identifies the competences you need to assemble and fit pipework systems to mechanical assemblies, in accordance with approved procedures. You will be required to prepare the work area, ensuring it is safe and free from hazards, to check the specified components are available and fit for purpose, to obtain all relevant and current documentation, and to obtain the tools and equipment required for the assembly operations, checking that they are in a safe and usable condition. In carrying out the assembly operations, you will be required to follow company procedures and specified assembly techniques, in order to assemble the pipework and components and to fit them to the mechanical assembly.

The assembly activities will also include making all necessary checks and adjustments to ensure that the pipework, when fitted to the assembly, is dimensionally accurate, is positioned and aligned correctly, is free from ripple, twists, creases and damage, and that joints are correctly secured and checked for leaks using the appropriate equipment and procedures. The assembled pipework must be checked for completeness and that it functions as per the specification.

Your responsibilities will require you to comply with organisational policy and procedures for the assembly activities undertaken, and to report any problems with the assembly activities, materials or equipment that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to ensure that all tools, equipment and materials used in the assembly are correctly accounted for on completion of the activities, and to complete all necessary job/task documentation accurately and legibly. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying pipework fitting and assembly techniques and procedures. You will understand the mechanical product being assembled, and its application, and will know about the equipment, relevant components and joining techniques, in adequate depth to provide a sound basis for carrying out the activities to the required specification.

You will understand the safety precautions required when carrying out the assembly activities. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
