Patent 11774027 was granted and assigned to Gas Technology Institute on October, 2023 by the United States Patent and Trademark Office.
A device and method for sealing a leak in a pipe. The device includes a sealing component that is placed against a pipe outer surface and over the leak. A clamp extending from the sealing component clamps partially around a circumference of the pipe and pulls the sealing component against the pipe. A vent in combination with the sealing member releases leaking gas through or around the sealing component while the sealing component is being secured to the pipe. The vent is then closed after full clamping is completed.
