Drilling machines are used to make connections to pipelines, tanks and plant piping without shutdown and are used to make hot taps in preparation for plugging machine applications. The 904 Drilling Machine is a manual or power-driven machine which taps into pipe while under pressure. It is used for making 1/2" through 4" (DN 15mm - DN 100mm) taps without shutdown. It can be used to install completion plugs in tapping nipples to permit recovery of tapping valves and to install TDW PIG-SIG® Scraper Passage Indicators.
The 904 Drilling Machine meets NACE Standard MR0175-93, sulfide stress cracking resistant metalic material for oilfield equipment.
