Pigging programs enhance pipeline integrity for Gas Distribution operators by reducing the risk of leaks through the removal of built-up liquids, contaminants, and deposits on the pipe wall. Cleaning pigs prepare the pipeline for evaluation, improving data capture and accuracy for the most valuable information possible.
Technical assistance is available from TDW subject matter experts for special circumstances or if the path to a solution requires consultation.

Hot tapping and plugging (HT&P) technology allows Gas Distribution market pipeline owners and operators to complete pipeline replacements and modifications – from making lines piggable to line lowering to relocations – all while their line is in service. TDW equipment and services are engineered for safety and efficiency, allowing operators to better protect their employees and the surrounding community.
The HT&P process incorporates a low pressure pipeline fitting, valve, taping machine, and isolation equipment, all working together to provide a safe and proven isolation solution. Once the area of pipeline that needs work has been safely isolated and evacuated, the line modification can be performed.
The full suite of isolation solutions offered by TDW plays a critical role in this process. The TDW STOPPLE® Train isolation system, for example, uses double block and bleed technology to help increase efficiency and safety during pipeline modification. The system only requires a single pipeline tap – reducing costs associated with fittings, valves, welding, and inspection services. The bleed port affixed on the line ensures that any product that bypasses the first seal is captured and evacuated through the bleed port, which creates a safe zone in high-consequence areas.
Whether operators are purchasing equipment to perform their own HT&P jobs or turning to TDW to execute the service for them, they can rely on the broad line of equipment and consumables by TDW. The company engineers and manufactures nearly every component needed for an HT&P project, and TDW tapping and isolation equipment is considered the industry standard.
TDW can also partner with operators before the work begins, providing consulting services to help them make optimum use of TDW products and services. TDW application engineers are recognized industry experts, ready to assist operators through each project phase – from start to finish.
