Field notes
The page lays out a casing-repair sequence from degreasing and crack drilling through layered deposition, cooling, machining, and optional hydrotesting. It distinguishes cold work on casings up to 25 mm from furnace heating to 600–650 °C, and names specific electrodes for nickel underlayers, hardfacing, and flange work. The site also lists refusal conditions, including white cast iron and casings left on active pipework.
