Deciding When to Replace It - When is That Old Boiler Shot

Low-pressure boilers (with a maximum of 15 psig) typically are patched by welding new steel plates in place of damaged steel, but high-pressure boilers become unsafe once structurally damaged. If a low-pressure steel boiler has had parts other than tubes repaired, such as shell or tube sheets, it is reasonable to assume the boiler is near the
