　　The corrosion phenomenon of a king combination nipple, use of the pipe will cause great impact, therefore, corrosion becomes a priority among priorities king combination nipple

　　At present, mainly used for fire water supply pipeline system, water supply pipeline has banned the use of galvanized pipe, so the corrosion easily ignored. According to the code for construction and acceptance of 3.3.15 sixth and 4.1.3 stipulates, threaded pipe installation hemp surplus should be clean and anti-corrosion treatment, galvanized surface and exposed the threaded part is destroyed when threading should be treated. If there are provisions pipeline anticorrosion paint design, according to the design rule do: if the design does not mention, suggest at least two brush primer, topcoat two. Brush paint process similarly must strictly according to the operating rules.

　　In practical engineering, king combination nipple cleaning and anti-corrosion treatment is a small and boring work, often do not pay attention to. At present the majority of projects are not to do as per requirements. Fire pipe brush paint, only in the galvanized pipe brush a red paint for approval, after a year or so are blistering off. Therefore, in the management of construction should strengthen quality consciousness.
