Overview

This unit covers the basic connection of refrigeration and air conditioning piping/tubing and fittings. It encompasses the safe use of hand, fixed and portable power tools for cutting, flaring, bending, swaging, silver brazing copper tube to copper tube, bundy tube and brass and steel fittings, measurement and reading drawings and diagrams.

Assessment

For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Evidence shall show an understanding of cutting, bending and joining refrigeration piping and tubing tools, equipment and techniques, applying safe working practices and relevant Standards, Codes and Regulations to an extent indicated by the following aspects:

T1 Piping

  • Refrigeration & water grade copper tube;
  • Maintaining cleanliness (always capped, do not blow out with mouth etc);
  • Soft and hard drawn tube;
  • Tubing applications (soft, hard, pair coil, water grade etc);
  • Tube qualities - diameter, wall thickness (gauge) and pressure ratings (R410A etc);
  • Pipe insulation (types - tube, slit tube, sheet etc and joining methods - glue, tape etc), and;
  • Other tube materials (Bundy, steel, aluminum, brass).

T2 Cutting

  • Cutting tools (Imps, normal & large pipe cutters, tube cutting rings etc);
  • Precautions while cutting (sharp burrs, sharp blades etc), and;
  • Deburring tools (reamers, deburrers etc).

T3 Bending

  • Bending tools (springs, levers, presses etc);
  • Precautions while bending (work hardening, collapsing etc), and;
  • Bending hard drawn tube - the process of annealing.

Required reading
