Abstract: The conventional firefighting pipe needs to be coated at the site, which leads to some shortcomings including low construction efficiency difficult operation, pollution risl high price of pipe coated internally and externally and its difficult promotion, etc. In thicle, a novel coated pipe for fire protection has been introduced in terms of manufacturin process, properties, relative advantage, installation and application, etc. It is revealed that compared with the traditional galvanized pipe for fire protection, the externally-coated fire fighting pipe can be regarded as a type of economic, practical and environmental friendly pipe because of its better comprehensive properties, lower running costs and more environmental friendly performance.
