Abstract
A method of cleaning and coating water conducting pipes is provided wherein a mixture of water and compressed air is forced through the emptied pipe system to rough clean such system, a pressurized acid is introduced into the pipe system and allowed to react with the interior surface of the pipes for a predetermined period of time. The acid is then drained from the pipes, and the interior of the pipes is dried by compressed air. A pressurized liquid plastic is then introduced into the pipes to coat the pipes with the excess plastic being subsequently drained from the pipe system.
Claims18
A method for cleaning and coating interior surface walls of a water-conducting pipe system comprising the steps of:
- a.) draining said water-conducting pipe system;
- b.) rough cleaning the interior surface walls of said water-conducting pipe system for forcing a mixture of water and air through the water-conducting pipe system;
- c.) fine cleaning the interior surface walls of said water-conducting pipe system by introducing a pressurized acid into the pipe system for an amount of time to fine clean the interior surface walls, said acid being capable of removing at least one of rust and calcareous products from the interior surface walls;
- d.) drying the interior surface walls of said water-conducting pipe system;
- e.) coating the interior surface walls of said water conducting pipe system with a coating material to prevent access of water conducted through the pipe to the interior surface walls of the pipe, said coating material being water resistant and capable of forming a smooth homogeneous surface;
- and
- f.) removing any excess coating material not adhering to said interior surface of said water-conducting pipe system.
