Title: Innovations by Steven A. Williams in Pipe Coating Technology
Introduction
Steven A. Williams is an accomplished inventor based in Stockton, California. He has made significant contributions to the field of pipe restoration through his innovative patent. His work focuses on enhancing the safety and longevity of underground pipes, which is crucial for public health and infrastructure.
Latest Patents
Williams holds a patent for a process designed to coat the interior surface of underground pipes. This invention addresses the leaching effects from water pipes made of materials such as lead, steel, and copper. The patent details methods, processes, compositions, and systems that can prevent harmful substances from contaminating drinking water. The 2-part thermoset resin coating is applied to the inner surfaces of pipes, utilizing a curing agent that is both phenol-free and plasticizer-free. This innovative coating can significantly reduce heavy metals, such as lead, from leaching to levels below approximately 10 µg/L (10 ppb). Furthermore, when cured, specific leachates like Bisphenol A and Epichlorohydrin from the coatings are reduced to less than 1 µg/L (1 ppb), with overall total organic carbon (TOC) levels measured at less than 2.5 mg/L (2.5 ppm). Notably, pipes treated with this coating can be returned to service within approximately 24 hours, and preferably within about 4 hours.
