- Regularly inspect external pipelines such as air ducts, steam water connection pipes, downcomers, and water supply pipes
1. Regularly inspect external pipelines such as air ducts, steam water connection pipes, downcomers, and water supply pipes, as well as bends, elbows, header heads, and pipe seats, to ensure that the expansion indicators are complete and correct. Any defects found (such as surface cracks, erosion thinning, or material issues) should be promptly addressed. When the wall thickness is less than the theoretical calculated wall thickness, they should be replaced immediately.2. For drainage and air pipelines that are prone to causing two-phase flow of steam and water, the focus should be on inspecting the fillet welds connected to the main pipe, the surroundings of the inner holes of the main pipe, elbows, and other parts, as well as the pipes, elbows, tees, and valves. After operating for 100000 hours, they should be replaced in conjunction with maintenance.The above is the inspection method for the pipes outside the heating furnace, hoping to be helpful to everyone.1.
