Assembling small bore non-ferrous pipework

​

This standard identifies the competences you need to assemble small bore non-ferrous pipework, in accordance with approved procedures. In producing assemblies, you will be expected to select and use a range of equipment, hand tools and techniques appropriate to the operations being performed.

The assembly activities will include producing soldered joints, brazed joints and compression joints. The pipe assemblies produced will use a range of fittings which will include straight connectors, elbows, tee pieces, reduction pieces, tank connectors, tap connectors, valves and other fittings, as appropriate to the application.

Your responsibilities will require you to comply with organisational policy and procedures for the pipework assembly activities undertaken, and to report any problems with the equipment, materials or assembly activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. 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 produce.

Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying small bore non-ferrous pipework assembly procedures. You will understand the pipework assembly, and its application, and will know about the assembly and soldering/brazing process, pipe components and materials used, in adequate depth to provide a sound basis for carrying out the activities, correcting faults, and ensuring that the work output is produced to the required specification.

You will understand the safety precautions required when working on the pipework assembly activities and with the associated tools and equipment. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
