Limpro Nacional’s X-Treme Seal (patent pending) multi-diameter pigs represent technological innovation, capable of traversing a variety of complex pipeline situations. In addition, Limpro Nacional has the ability to produce large diameter foam pigs such as 54-in. by 11.5 ft and more.
Besides being at the forefront of technological innovation, Limpro Nacional also manufactures a full range (2 to 54 in.) of foam pigs, steel mandrel pigs, steel and pencil brushes, urethane cups and discs and solid cast pigs for cleaning, batching and gauging with different configurations available for regular and special operations. Further, replacement parts manufactured by Limpro Nacional fit most available pig bodies in the market.
Limpro Nacional, a privately owned company headquartered near Monterrey, Mexico, was founded in 1987 after recognizing the need for engineering materials to serve the oil and gas industry with durable, wear- and tear-resistant materials. Having identified polyurethane as the choice polymer to face the challenge, due to its versatility and wide range of properties to meet the multiple requirements, Limpro Nacional started manufacturing “Polly pigs” and pipeline cleaners that at the time were not fully manufactured in Mexico.

A stellar reputation is earned, not manufactured. Since its inception, Precision Pigging has steadily introduced to the pipeline integrity management industry both cutting-edge technological advancements, as well as advancements in the way clients should expect to be treated by their geometry/deformation vendor. As a result, the company enjoys consistent word-of-mouth industry recommendations regarding its commitment to providing exceptional customer service and accuracy in pipeline anomaly detection.
Now celebrating 15 years in providing client-driven, cost-effective, high resolution geometry/deformation inspections throughout North America and beyond, Precision Pigging continues to build on its successes. In the last year, the company has doubled its workforce and looks to expand hiring efforts again this year.
What all of this expansion means to Precision Pigging’s clients is, quite simply, more. More capability to provide rapid deployment of inspection crews and equipment on a client’s changing schedule. More capability to provide further enhancements to Precision Pigging’s already state-of-the art technology. More ability to provide customized integrity inspection solutions. More means that Precision Pigging will continue to lead the industry by maintaining a first-run success rate of 97 percent, a probability of accuracy (POA) of 98 percent and an probability of detection (POD) of 99 percent.

The V-JET Pig by T.D. Williamson is a patented design jet pig that uses the differential pressure created across the tool during normal movement down the pipeline. The jetting action pulls liquid from the bottom of the pipe in advance of the pig and sprays it back in front of the tool in the form of a fine mist, which covers the upper section of the pipe. The spray improves the application efficiency of injected chemicals like corrosion inhibitors, scavenging agents, biocides, filming compounds and cleaning chemicals.
Although the V-JET pig was specifically designed for corrosion prevention, it is equally useful for cleaning and dewatering applications. It’s particularly effective at moving ponding liquid — which is prone to reducing the application efficiency of normal chemical injections — back into the flow stream, increasing the coverage of the hard-to-cover locations at the top of the pipe.
For coupon monitoring, the V-JET pig is often part of an overall program to monitor application of a customer’s chemical treatment. This is accomplished by inserting monitoring coupons prior to application and then examining the coupons afterward to assess how well they were coated. The coupons are then pulled periodically to monitor how well the chemicals are continuing to prevent corrosion. For more information, visit TDWilliamson.com.
