Corrosion is fast becoming one of the most critical threats in pipelines and pipeline systems. Uncontrolled, corrosion will result in loss of pressure containment. Corrosion can also affect flow efficiency through increased friction on the pipe wall, and the resulting debris can damage the pipeline and associated equipment, as well restrict flow and reduce capacity. TDW provides a suite of solutions to combat corrosion.
TDW offers products and services that enable Gas Distribution operators to:

Pigging programs scaled to Gas Distribution operators’ needs help limit corrosion damage and enhance pipeline integrity by removing built-up liquids, contaminants, and deposits on the pipe wall. Pigging also facilitates the application of corrosion inhibitors to protect pipelines from corrosive agents. In addition, using cleaning pigs to prepare the pipeline for inline inspection (ILI) helps improve data capture and accuracy for the most valuable information possible.
Cleaning, pre-ILI preparation, and corrosion control:
Removing built-up liquids:

TDW provides non-destructive in-ditch assessment of internal and external corrosion, from localized areas up to entire joint lengths. By incorporating operator interaction rules with TDW corrosion mapping capabilities, TDW can provide Gas Distribution operators highly accurate and useful information to help address pressing corrosion issues before they become critical and prioritize remediation activities.

TDW offers Gas Distribution pipeline owners and operators hot tapping and plugging (HT&P) solutions for a wide array of pipeline defects and maintenance challenges from dents to corrosion to valve failure. TDW equipment and services are engineered for safety and efficiency, which helps protect people and the community.
The HT&P process incorporates a low pressure pipeline fitting, valve, tapping 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.
TDW isolation technology plays a critical role in this process, and a temporary bypass allows work to be performed without the need to stop product flow. The TDW STOPPLE® Train isolation system, for example, uses double block and bleed technology to help increase efficiency and safety during pipeline modification. This approach to line isolation, which only requires a single pipeline tap, reduces 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 contained and evacuated through the bleed port, which helps operators better protect people and the environment.
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 company’s broad line of equipment and consumables. TDW application engineers are recognized industry experts, ready to assist operators through each project phase — from start to finish.
