Application

This unit describes the skills and knowledge required to design in the field, plastics pipelines operating under high pressure and temperature.
The operator may work alone or as a member of a team.
The principally refers to experienced operators who are required to select materials, components and designs for specific high temperature and pressure applications of plastic pipelines to requirements, and specify appropriate testing and commissioning with high pressure water.
No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
