Title: Thomas L. Pugh and Pipeline Lining Innovation.
Introduction
Thomas L. Pugh is an inventor associated with Ponca City, Oklahoma, and Conoco Inc. His patent describes a method for installing a continuous tubular plastic liner inside a pipeline.
Latest Patents
Pugh’s listed patent, “Lining of Pipelines Using a Continuous Tubular Pull-Through Plastic Liner,” uses temperature changes to help fit a liner inside a pipeline. The plastic liner has a greater coefficient of thermal expansion than the pipeline. Cooling reduces the liner’s outside diameter so it can be pulled through the pipeline. As both components return to normal temperature, the liner expands to conform to the pipeline’s interior. Pugh is credited with 1 patent in the information provided.
Career Highlights
Pugh’s documented invention addresses the practical challenge of lining pipelines with a continuous plastic tube. The method uses cooling and subsequent expansion to position the liner within the pipeline.
Collaborations
Pugh’s listed coworkers include Mamdouh M. Salama and Louis H. Wolfe. The available information identifies these professional associations but does not specify their roles in developing the patent.
Conclusion
Thomas L. Pugh’s patent presents a temperature-assisted approach to pipeline lining, using a plastic liner that contracts for installation and expands to fit the pipeline as it warms.
