This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Learners who demonstrate competence as described in the outcomes of this unit standard will be able to demonstrate understanding of gas pipeline installation systems and equipment.

The qualifying learner is able to:
  • Describe typical gas pipeline applications in South Africa.
  • Describe typical gas pipeline and pipe network layouts and -configurations.
  • Describe different pipeline system components.
  • Describe different pipeline and pipe network control equipment and systems.

    This unit standard will contribute to the full development of any learner within the gas installations environment, by providing recognition, further mobility and transportability within the field. The knowledge, skills and understanding demonstrated in this unit standard are essential for upliftment, social and economic transformation in the gas installation environment. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Learners accessing this unit standard will have demonstrated competence against communication and mathematical literacy at NQF Level 2 or equivalent.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
