T.D. Williamson – Pipeline Solutions

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. In 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.

TDW 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. Developed 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. Repairing 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. In-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.

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. Pig 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. A 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. With more than 800,000 kilometers 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.
