CURTISS-WRIGHT Pop-A-Plug Stopper for Small Tubes
CURTISS-WRIGHT Corporation EST Group POP-A-PLUG
A method for sealing both ends of a pipe without welding in the event of a leak in heat exchangers, such as water heaters and numerous small tube heat exchangers, using the EST Corporation's POP-A-PLUG.
In heat exchangers that use many small tubes, such as water heaters and condensers, they are used to seal both ends of the tubes without the need for welding in the event of a leak. Heat exchangers have several small tubes running through them, and these tubes can develop holes and leak due to aging or the fluid. This reduces the efficiency of heat exchange, so the leaking tubes or the ends of the tubes before they leak are sealed to minimize the decrease in efficiency as much as possible. Disadvantages of welding plugs: ◎ It takes time. ◎ Documented procedures are required. ◎ Due to space constraints, welding may be difficult. ◎ Preheating and post-weld heat treatment may be necessary. ◎ There is a possibility of cracks occurring near the weld bead after the unit resumes operation. ＿／＿／＿／＿／＿／＿／＿／＿／＿／＿／＿／ Horiguchi Engineering Co., Ltd.
