This unit specifies the skills and knowledge required to determine installation requirements and to fabricate up to DN50, install and test steel pressure piping.It applies to pipe systems with operating pressures not exceeding 1750 kPa and 200°C.
Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & performance criteria requirements, incl the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills:
* applying pipe cutting and welding skills by using oxy-acetylene and arc welding equipment for piping up to DN50 and must include:
* butt welding a pipe joint in DN40 piping in the fixed horizontal position
* welding DN40 and 50 mild steel branch joints
* constructing a DN80 header with DN20, 40 and 50 branch joints using the oxy-acetylene method
* welding 50 mm and 80 mm flanges to mild steel pipe
* welding blank ends into DN80 mild steel pipe
* fabricating, installing and testing a DN40 steel pipeline from a supply point to an outlet, incorporating two changes of direction with one position butt welded with oxy welding, plus an arc welded flange incorporating a branch for testing purposes
* testing completed task to ensure required pressure and the soundness of all joints within the system.
The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by Victoria University and/or via the Victoria University e-learning system.
