Patent number: 11448352Abstract: A pin and ring-type plug assembly for plugging a heat exchanger tube to provide a leak resistant seal is provided. The plug assembly is designed such that it can be used to form a high-pressure seal relative to a wide of range of tube inner diameters. The angle of taper of the pin varies along a length of the pin such that the angle of taper is steepest at or adjacent a nose section of the pin and is shallowest at or adjacent an end section of the pin.Type: GrantFiled: March 4, 2021Date of Patent: September 20, 2022Assignee: EST GROUP, INC.Inventors: Danko Kobziar, Ka'ren Sarkissian, Andrew Hall, Alex Kotlyar

Patent number: 10488295Abstract: A pneumatic test gun for use in performing a leak test on a tube is provided. The pneumatic test gun has a handle for being manually gripped by an operator, a distal end portion for insertion into a tube to be tested, and a proximal end plate from which the distal end portion extends and which is adapted to be abutted against an open end of the tube to be tested. The distal end portion includes a support tube providing a flow path for compressed air into a tube to be tested, a longitudinally-compressible and radially-expandable annular seal located on the support tube, and a self-activating retaining element assembly adapted for radial-expansion into engagement with an inner diameter of the tube to be tested to improve retention of the distal end portion within the tube when the tube is pressurized during a leak test. A method is also provided.Type: GrantFiled: November 9, 2017Date of Patent: November 26, 2019Assignee: EST GROUP, INC.Inventors: Ka′ren Sarkissian, Alex Kotlyar, Danko Kobziar, Andrew Hall, Michael Hvorecny

Patent number: 9823155Abstract: A test plug for insertion into and plugging of an open end of an elbow pipe is provided. The test plug includes a resilient sealing element and set of gripper segments carried on a shaft. The set of gripper segments are movable relative to the shaft between pipe-gripping and pipe-non-gripping positions such that, when the test plug is placed in sealing and gripping engagement relative to an inner diameter wall of an elbow pipe, the set of gripper segments are positioned in eccentric relation to at least one of the sealing element and the shaft.Type: GrantFiled: August 17, 2015Date of Patent: November 21, 2017Assignee: EST Group, Inc.Inventors: Ka'ren Sarkissian, Alex Kotlyar, Danko Kobziar
