| ONE-SIDED SETS |
a) Closing ending branch line (e.g. shortening a pipeline section)
b) Closing a pipeline branch for repair. The branch line does not require gas supplies during the repair
| TWO-SIDED SETS |
a) Closing for a pipeline section replacement where the gas supply may be interrupted
b) Both side closing for the purpose of pipeline replacement or installation of branch line
| THREE AND MORE-SIDED SETS |
Closing of pipeline sections on a complex configuration gas distribution pipeline
