The SHORTSTOPP® 300D Split Tee is an extruded-style split tee. The fitting is furnished with a flange that is drilled, faced, and pressure rated to match ASME Class 300 flanges. It is used with TDW hot tapping and/or plugging machines to tap and temporarily plug the line for maintenance or repair, without shutdown. The flange is machined to accept 300D Completion Plugs. Quality control measures include inspection to ensure a proper fit on the pipeline; flange alignment verification; and radiographic weld inspection to API Standard 1104. The maximum operating pressure of the SHORTSTOPP® 300D Fitting is 740 psi (51 bar) at 100°F (38°C). The maximum operating temperature of the SHORTSTOPP® 300D Fitting is 180°F (82°C) at 675 psi (47 bar).
TDW also provides the 4"-12" 300D Split Tee with a completion plug with guide bars., These guide bars block the tapped hole, keeping the line piggable.
All fittings are stamped with a code number for material identification, and a painted band ensures easy alignment in the field. Material certificates are available. The 4" (100mm) and larger fittings are complete with blind flange, studs, nuts, gasket, O-ring, and completion plug. The 2" and 3" (50mm and 80mm) sizes are furnished with a threaded cap, completion plug, and O-ring.
