Pop-A-Plug (Closure plug for heat exchanger tubes)
This is a mechanical plug for closing off heat exchange tubes. It is a revolutionary maintenance method that eliminates the need for welding closures in high-pressure equipment.
In the maintenance of heat exchanger tubes, I believe that the current methods involve driving in taper pins to seal leaking tubes or using seal welding for high-pressure equipment. The Pop-A-Plug from Curtis Wright in the United States uses a specially machined mechanical structure plug that is sealed with a dedicated tool. It maintains pressure resistance up to about 40 MPa, and seal welding after plugging is not required (the maximum pressure resistance varies by size). Welding work requires time for the work itself, pre-treatments such as heat treatment, applications related to the use of fire, and inspections during the welding process. However, Pop-A-Plug can reduce this workload and does not use heat, so there is no damage to the equipment. It is a sealing method that can significantly shorten the recovery period of the equipment. *According to ASME PCC-2-2022, the guidelines for the maintenance of pressure equipment, Pop-A-Plug is recommended as a tube plug for heat exchangers. *For more details, please download the PDF or contact us.
