Paraffin wax, hydrates, corrosion, construction debris, etc., can create an obstruction inside a pipeline that can restrict flow. At its worst, a line blockage can shut down production altogether.
TDW offers specific pigging technology to help Liquids Transmission operators manage the build-up and prevent pipeline blockage. In the event of a blockage, TDW can also provide intervention technology to access the blocked area and provide by-pass while the blockage is removed.

A comprehensive pigging program can remove solids and sediments that block pipeline flow for better performance and profitability. TDW can help Liquids Transmission operators select the best cleaning pig for the purpose, pipeline, and product.
Technical assistance is available from TDW subject matter experts for special circumstances or if the operator’s path to a solution requires consultation.

In the Liquids Transmission market, where pipeline shutdown may not be an option, hot tapping and plugging (HT&P) technology allows operators to overcome line blockages with minimal flow interruption. TDW HT&P solutions protect customers’ revenue stream while minimizing risk – and are available for a wide spectrum of pipelines, environments, and products.
The HT&P process incorporates a high pressure fitting, valve, tapping machine, and isolation technology – 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 – 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 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 TDW equipment and consumables. 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.
