TDW PIGGING INSIGHTS - Episode 5
A quick guide to opening 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.
OPENING
To safely open the TDW D2000 clamp ring closure door, follow these procedures:
Isolate the vessel from line pressure, bleed the pressure to 0 psig and drain.
Always stand on the side of the closure that is opposite the door hinge.
Open the pressure warning lock by turning the screw counterclockwise. If there is still gas in the line, tighten pressure warning lock and continue to bleed pressure until 0 psig, then continue procedure again.
Inspect the pressure warning lock, O-Ring and the bushing.
Lift the clamp ring handle and put the pressure warning lock in the hole furthest to the right.
Clean and lubricate the interior surface of the clamp ring.
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
