摘要

The cutter for gas pipes (1) comprises a saddle (2) which carries a threaded connection (21). A sealed hood (6) is mounted over this. A cutter (4) with an externally threaded shaft (3) fits into the connector and has channels through which the gas can flow. An independent claim is included for a method for cutting gas pipes, e.g. for fitting a branch, using the cutter.
