Abstract: The methods for cleaning pipes with service connections includes vacuuming therethrough abrasive projectiles first in one direction, and thereafter, in an opposing direction, with additional cleaning achieved by opening of service connection valves during vacuuming. By opening service connection valves during vacuuming, debris and moisture are removed from within the service connections. Vacuuming direction reversal removes shadow deposit areas.

Abstract: The method to radially displace liquid liner inside a pipe includes the step of flowing the liner around a distributive body placed within a pipe gas stream. As the gas streams past the distributive body, the liner coats the pipe homogeneously from top to bottom.
