Hi, Like to know the reason a plug has to be seal-welded to the tube of a heat exchanger. It just so happens in the plant I am working, when a Turnaround take place, all heat exchangers with tube seal boiler and heat exchanger tube Plasma weldingExpanded plus seal welded tube to tubesheet jointJan 18, 2012Equipotential Bonding Of Cable LaddersJan 14, 2008welding sockolets and threadolets on to pipeJan 18, 2007Welding and PWHT Valves into Pipe LinesJan 18, 2004See more resultsSA 249 Stainless Steel - Alloy Pipe, Tubes, Ceramic lined boiler and heat exchanger tube Plasma weldingAnnealing often is done on the tube mill and in a hydrogen atmosphere, which reduces surface oxide films and heat tint from welding. The result is a solution-annealed, recrystallized weld and a clean tube that forms a naturally occurring passive surface oxide film as soon as it leaves the annealer and is exposed to oxygen in the atmosphere.Repair of Exchanger tubes according to ASME PCC-2The Pop-A-Plug® image below system is a mechanical tube plug to seal leaking or degraded high-pressure heat exchanger tubes. The design ob-jective was to produce a fast and simple to in-stall mechanical tube plug with the same or bet-ter installed stability than a friction fit or welded plug.
