scope:

Butt fusion joining of PE pipe is a relatively simple, forgiving, and dependable process. However, as with any kind of pipe installation, proper procedures and diligence must always be used to consistently make satisfactory joints. Fusion machine operators should demonstrate an aptitude for using mechanical equipment and be generally familiar with laying pipe. They should have a demonstrated ability to follow procedures and be conscientious in their work. The amount of time it takes to provide the specified training can vary greatly and depends on the number of individuals being trained as well as their aptitude and willingness to follow directions. However, participants shall not be considered "trained" until they have demonstrated proficiency on at least two test joints made under circumstances and field conditions representative or similar to those of the project.

PURPOSE

The purpose of this document is to provide a general outline of PPI's recommended minimum guidelines for training an operator in properly and safely making good quality butt- fusion joints in PE pipe systems. This training guide is intended to recommend a consistent minimum level of fusion operator proficiency; certain installations may require additional operator training and proficiency.
