CLOSING TDW D2000 CLOSURES

TDW PIGGING INSIGHTS - Episode 6

A quick guide to closing and maintaining the D2000 Closure.

D2000 Quick-Actuating Closure

The D2000 quick-actuating closure combines operator safety with ease of operation. After depressurization, opening and closing operations are performed in a fast, single motion, with the operator standing safely to the side. The D2000 closure maximizes efficiency and reduces both, personal operator risk and company operational cost.

CLOSING PROCEDURES

  1.  Before closing, inspect, clean, and lubricate the O-Ring on the barrel collar, including the O Ring grooves and sealing surfaces

  2. Push the door firmly shut with no gap between the door face and hub face.

  3. Pull down on the clamp ring handle to close the door.

  4. Install the pressure warning lock screw, make sure it is not cross threaded.

  5. Hand tighten the pressure warning lock screw and then add about one eighth of a turn with a wrench.  Do not over tighten.

MAINTENANCE TIPS TO BE DONE REGULARLY

  • Lubricate all the pivot point on top of the clamp ring assembly, front and back, as well as door hinge, top and bottom

  • Keep all the exterior surfaces painted to prevent rust
