Flat Bottom Tees

Flat Bottom Tee

TDW offers a full line of flat-bottomed tees that eliminate the need to install valves on connections during hot tap tie-ins of lateral taps and crossover connections. With a weld bevel that can be field scarfed, the tees are highly flexible, making them suitable for use in hot tapping and plugging operations with special requirements.

In addition, the side outlet of the tee can be plugged using the TDW SHORTSTOPP® II plugging machine in order to isolate flow and pressure in connecting lines. For pressures of 10.3 bar (150 psi) to 20 bar (285 psi), special side outlet plugging equipment is available.

Flat-bottomed tees come in a variety of sizes. The 1.25-inch through 3-inch sizes are threaded, while 4-inch through 12-inch are flanged.

Key features:

  • Maximum working pressure of 20 bar (285 psi) at 38°C (100°F) or 17 bar (245 psi) at 82°C (180°F) per ASME B31.4 (with plugging equipment removed).
  • Compatible with nearly all ASME 150 applications.
  • Optional factory scarfing available for unique applications.
