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

Tie-In Solution for Pigging-Compatible Natural Gas Pipelines
An elegant tie-in solution was necessary for maintaining the piggability of main pipelines. Two 12-inch natural gas lines needed to be connected to a new well site near Pittsburgh. An innovative solution was used with TDW fittings and pig guide bars.
When maintaining the piggability of main lines was crucial, an elegant tie-in solution WAS necessary.

Project Overview
A new natural gas well was being completed near Pittsburgh, necessitating the connection of two 12-inch lines from the well site to two 12-inch main lines. The 12-inch main lines needed to remain piggable.
Design & IMPLEMENTATION
To meet these requirements, an innovative solution using TDW 12-inch x 12-inch 600 class 3-WAY™ Tee Fittings with LOCK-O-RING® and pig guide bars was used. The LOCK-O-RING® completion plug features an interlock system that helps eliminate potential leak paths and ensures proper seating. The implementation process included:
Fitting Installation: The 3-WAY™ Tee Fittings were welded onto the 12-inch main lines.
Pipeline Connection: The 12-inch pipes with valves were welded to the 12-inch outlets on the fittings.
Hot Tapping: TDW service technicians performed two 12-inch Hot Taps.
Completion Plug Setting: The completion plugs with pig guide bars were set into the fittings by the TDW service technicians.

This approach allowed for the seamless integration of the new well site while maintaining the piggability of the main lines. By utilizing TDW's advanced fitting and plug technology, the tie-in solution not only met the immediate operational needs but also provided long-term reliability and safety for the pipeline system.

Overview of TDW Pig Parts and Their Uses
TDW Pig Parts
TDW designs and manufactures an extensive selection of pipeline pigs for specific applications, such as liquids displacement, cleaning, batching, gauging.
Pigs have various components, and each pig comes in a multitude of configurations. This blog looks at some of the key parts that make up a pig and explains the uses of these parts.
pig PArts and their uses
Discs: Are effective at pushing out solids and providing a good support for the pig.
Conical Cups: Provide excellent sealing characteristics, good support and long wear.
Bypass Ports: These allow some of the flow to bypass through the pig and help minimize solid build up at the front of the pig.
Spring Mounted Brushes: Provide a continuous forceful scraping for removal of rust, scale and other build ups on the wall of the pipe.
Circular Brushes: The brushes are bi-directional and can be stacked for scraping for removal of rust, scale and build-ups.
Pit Boss/Pencil Brush: Scrapes deep into pits to remove build-ups.
Gauge Plate: For discovery of deformities/obstructions in the line, also commonly used prior to ILI runs.
Magnets: Pick up ferrous materials and give indications to loose debris in the line.
