Improving corrosion inhibition
Spray pig helps offshore gauge success of corrosion inhibitor applications.
TDW provides hot tapping services and equipment that enable pipeline owners and operators to safely, efficiently, and cost effectively perform pipeline modification and repair activities without shutdown and with minimal disruption to product flow.
Learn MoreIn addition to saving pipeline owners and operators time and money by eliminating the need to blow down miles of line in between valves, line isolation plays an integral role in performing a variety of both planned and unplanned activities, including routine maintenance, new construction, expansions, and emergency interventions.
Learn MoreTDW designs and manufactures high-performance valves that improve safety and efficiency when conducting tapping and isolation operations on in-service pipelines, tanks, and storage vessels.
Learn MoreTDW designs and manufactures a full suite of low-pressure fittings that enable operators to perform work on pipelines, tanks, and storage vessels without shutdown.
Learn MoreDeveloped through more than 95 years of experience in the pipeline industry, high-pressure fittings from TDW are furnished with patented features that can help operators safely and efficiently repair and maintain high-pressure lines without shutdown or interruption of service.
Learn MoreRepairing defects, dents, gouges, corrosion, and leaks in pipelines can be a costly and resource-intensive task. For more than 60 years, TDW has worked to make that task less costly and more efficient by offering a range of repair and reinforcement products that are capable of permanently restoring pipelines to their maximum operating pressure without having to replace the entire section.
Learn MoreIn-service pipeline welding requires a great deal of knowledge, experience, and expertise to be completed safely and cost-effectively. Improper execution of welding can present any number of risks - from burn-through to hydrogen cracking to material degradation - that can compromise the integrity of the pipeline, as well as the safety of the people and environment around it.
Learn MoreTDW provides the most comprehensive hot tapping, plugging, pigging, and composite wrap installation instruction available in compliance with Department of Transportation covered tasks standards requirements.
Learn MoreAs part of the total TDW HT&P solution, the ProSeries ™ offering is engineered and manufactured using model-based processes. The result is reduced lead time, substantially faster deliveries, consistent quality, and compliance.
TDW manufactures one of the industry's widest ranges of purpose-built pigs. This vast inventory includes cleaning, batching, gauging, liquids displacement, and specialty pigs, available in multiple diameters and designed to meet specific pipeline and product demands. Customization and configuration options ensure tailored solutions for even the most complex pipeline conditions.
Learn MorePig passage indicators - commonly referred to as PIG-SIGs, a term TDW originated more than 60 years ago - accurately detect pigs, spheres, scrapers, and other tools as they pass distinct points along the pipeline.
Learn MorePig tracking equipment enables operators to detect the exact location of pigs as they travel through the pipeline. By utilizing this technology, pipeline operators or service crews can respond rapidly to stalled pigs, which may pose an operational risk to the pipeline.
Learn MoreThe ability to pig a pipeline for cleaning, maintenance, and inline inspection (ILI) is essential to integrity assurance. But a lack of launchers and receivers - the equipment that allow pigs, spheres, and ILI tools (often referred to as smart pigs) to enter and exit the pipeline while product flow continues - makes pigging impossible.
Learn MoreRegular cleaning of pigs and other job site tools has an additional benefit: it extends their lives and helps avoid repair and replacement costs. With the TDW solvent-free, automated pig washer, pipeline owners and operators can efficiently and effectively maintain pigs and other tools at their shop or service center.
Learn MoreOne of the most critical operations in pigging is opening the closure, which provides access to the pig trap during both launch and recovery operations. When the closure door is opened during the insertion or removal of a pig, there is a risk of explosive gas-air mixture.
Learn MoreA well-planned, regular pigging regimen can help operators prolong the life of their pipelines, save money, maintain product flow, and minimize product sediment. TDW has more than seven decades of experience designing, manufacturing, and using pigging products, and our experienced technicians will work with operators to select the right pigs - and the right pigging program - for their pipeline and product.
Learn MoreTDW provides the most comprehensive hot tapping, plugging, pigging, and composite wrap installation instruction available in compliance with Department of Transportation covered tasks standards requirements.
Learn MoreWith more than 800,000 kilometers (500,000 miles) of inline inspection (ILI) completed, TDW has the experience and expertise to help pipeline owners and operators achieve system integrity and reliability, resulting in an extension of the asset lifecycle. Our dedicated personnel - powered by knowledge and focused on mitigating risk - partner with you to meet rigorous safety, regulatory, operational, and corporate demands.
Learn MoreIn-situ non-destructive evaluation (NDE) methods are used to verify and drive the accuracy of inline inspection (ILI) results while pipelines remain in service, enabling you to better characterize defects, prioritize repairs, and keep your product flowing.
Learn MoreField-proven with hundreds of offshore projects, SmartPlug double block and monitor (DBM) technology minimizes platform downtime by enabling operators to isolate pressurized pipelines so equipment maintenance, repairs, and replacements can be done without bleeding down the entire system.
Learn MoreThe SmartTrackTM two-way communication system enables pipeline operators to improve the safety of pigging operations by providing real-time monitoring of pigs and tools within the pipeline. Not only does the SmartTrack system accurately track, position, and identify pigs and tools in thick-wall buried or subsea pipes, it can also be used to track and identify all SmartPlug isolation tools.
Learn MoreFor more than five decades, TDW has helped pipeline owners and operators overcome complex subsea challenges - from tie-ins and decommissioning to pipeline emergency repair - efficiently and cost-effectively.
Learn MoreFeasibility studies help pipeline owners and operators determine the most viable and safest solutions for offshore interventions, including the specific application of SmartPlug isolation technology and the SmartTrack pig tracking system.
Learn MoreBy preventing flooding as a result of wet buckle during offshore pipe lay operations, the SmartLay system mitigates risk to the pipe lay vessel and crew, protects as-laid pipeline, and helps pipeline owners and operators eliminate costs associated with standby dewatering spreads. SmartLay technology can be used in either shallow or deep waters.

Spray pig helps offshore gauge success of corrosion inhibitor applications.
Injection or batching of corrosion inhibitor fluid is an essential part of a maintenance program aimed at reducing pipeline deterioration. Unfortunately, gravity often forces inhibitor fluid to settle along the bottom of the pipe, leaving the top vulnerable.
Designed to overcome gravity, the TDW V-Jet® VXP Corrosion Inhibitor Pig provides a more complete coating – and better protection – for all pipe wall surfaces. Mounted to the front of a special pig configuration, V-Jet pigs use bypass flow as a vacuum, literally sucking up residual corrosion inhibitor that has dropped to the bottom of the pipe wall and spraying it onto the inside top portion.
The V-Jet VXP corrosion inhibitor pig is designed for smaller pipeline diameters, from 4 inches through 12 inches. The V-Jet corrosion inhibitor pig is used in pipeline sizes 10 inches through 28 inches.
