Abstract: not available for EP0764062Abstract of corresponding document: DE19513150A process for cleaning and coating pipes or pipework, especially those used to convey water, in which the pipe or pipework (1) is cleaned with an acid and coated with synthetic material and in which, for coating purposes, the pipe or pipework (1) is filled with liquid plastic which is drained off after the pipe or pipework (1) has been coated. The time taken to implement the process and damaging effects of the acid are reduced in that the acid is poured through the pipe or pipework (1) and replaced by a neutralising agent after the cleaning process and the neutralising agent is drained from the pipe or pipework (1) after neutralisation and before coating.
