Inside job...: Large-diameter sewer and drain lines can benefit from pipe lining technologies, too

摘要

Most plumbers have at least basic familiarity with epoxy lining a building's potable water system as an alternative to a repipe with a whole new plumbing system. The strategy is simple enough - uncap and dry out the lines, blast through an abrasive like aluminum oxide powder to get rid of the crust and corrosion and to give the inside of the pipe some "tooth" so the epoxy blend blown into the system in the next step will have something to grab onto. Pipe lining is basically a method for bringing new life to old, corroded pipes, mitigating internal corrosion and collapsed pipes. Or, as Tom Bowman, domestic and international license manager for Nu Flow Technologies said, it's an infrastructure fix.
