T-101 Drilling Machine


The T-101 drilling machine is designed for making ½-inch to 4-inch hot taps in pipelines under pressure. In addition, it can be used for installing 2-inch and 3-inch completion plugs in tapping nipples, and for installing TDW PIG-SIG® passage indicators.

The machine is available in two different models:

  1. Standard: 18 inches of boring bar travel.
  2. XL: 28 inches of boring bar travel.


Both models meet NACE standard MR0175-93 (sulfide stress cracking resistant metallic material for oilfield equipment).

With an operating temperature range of -29°C (-20°F) to 371°C (700°F) at 48 bar (700 psi) for intermittent service, the T-101 is highly versatile and can be used in a wide range of tapping and plugging applications when pipeline shutdown is not an option.

  • Maximum continuous rating of 177°C (350°F) at 70 bar (1,025 psi).
  • Maximum working pressure of 100 bar (1,480 psi) at 38°C (100°F).
