Latest Patents

Lindsay Ewing holds a patent for a "Polyolefin coupler for joining polyolefin pipes." This invention features a coupler that consists of a length of cross-linked polyethylene pipe with spiral grooves cut into both its outer and inner surfaces. A heating element is wound in the groove, allowing the coupler to expand mechanically for easy fitting over the ends of polyethylene pipes. The heater element is energized, causing the coupler to shrink and form fusion welded joints with the pipes. Notably, no preparation of the pipe ends is necessary, as the serrated inner surface effectively bonds to the material beneath the oxidized skin. This coupler is particularly advantageous for larger sizes of 500 mm or above. Additionally, instead of using an electric heater, radiant energy such as infrared or light can be employed to heat the coupler.
