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.

GPT EVOLUTION INSTALL USES ZEVAC
A gas operator installing an 8in GPT EVOLUTION isolation gasket utilized ZEVAC to capture and recover vented gas. This made the operation emission free.

Isolation gaskets are installed to protect lines from corrosion and unintentional leaks. Inmost cases, installing these gaskets requires sections of pipelines to be evacuated and purged, often by gas venting. The practice of venting creates intentional natural gas emissions, releasing methane into the atmosphere. It is a paradox to vent while protecting against leaks.
A gas pipeline operator in Pennsylvania needed to install an 8in GPT Evolution Isolation gasket at a well pad north of Pittsburgh. Instead of venting before installing and releasing emissions into the environment, they utilized ZEVAC services to capture and recover the vented gas. To draw down 200ft of 8in line from approximately 200 psi down to zero with ZEVAC took approximately one hour from set up to the point when the gas in the section had been re-compressed into an adjacent line.
Company personnel were then able to install the GPT EVOLUTION gasket. This gasket is fully encapsulated and just 1/8in thick for easy installation. The GPT EVOLUTION is extremely abrasion and impact resistant due to the proprietary coating. It is also fire safe and does not have lamination.
This project protected their pipeline and protected the environment.
