Four Steps of Progressive Pigging
Mitigate unnecessary losses and maximize pipeline throughput.
Pigging Solutions Extend Life of Pipelines, Optimize Product Flow
Pigging is a vital component of ongoing pipeline maintenance and operation, but its value extends far beyond those roles. Pipeline owners and operators also use pigs to protect their product purity, remove unwanted materials and items from their line, prepare for pre-commissioning and inspection testing, and confirm pipeline defects. TDW, a global pigging solutions provider, delivers customized solutions for operators’ needs.
From cleaning to confirming suspected pipeline deformations, TDW offers pigs (scrapers) for a wide variety of jobs:
Parts and Equipment
If a pipeline owner or operator needs to repair or maintain pigs in the field, TDW offers a wide selection of replacement parts and equipment, including:
If operators aren’t sure which pigging solution is best for them, or if they’re interested in setting up a regular pigging regimen, the experienced engineers at TDW can provide guidance and recommendations.
Pig Features and Extras
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.
Pig 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.
The 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.
Regular 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.
One 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.
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.
TDW provides the most comprehensive hot tapping, plugging, pigging, and composite wrap installation instruction available in compliance with Department of Transportation covered tasks standards requirements.
