The Process
Pipe Preparation and Cleaning
The existing pipe system is inspected for integrity, and
spot repairs on excessively worn joints and fittings are made where necessary.
Valves are removed and their locations are temporarily fitted with unions and/or
couplings used during the restoration process. Sitting water is drained from the
pipe system and air is introduced into the system to test for leaks. The pipe
runs being restored are then dried with heated compressed air to remove all
moisture. An air medium is introduced to distribute an abrading agent throughout
the pipe to remove all rust and corrosion material. The removed corrosion
material is then gathered into a collection unit. Air is again surged through
the pipe to remove any residual debris and remnant dust.
Epoxy Lining the Pipes
The cleaned pipe system is re-heated to create an optimal internal pipe surface
environment prior to epoxy coating. An air pressure leak test is again performed
prior to coating. Conditioned air is then introduced into the pipe to uniformly
distribute the epoxy lining throughout the pipe segment. Following the coating
application, continuous controlled air is sent through the piping to facilitate
epoxy curing.
Reassembly
The system is reassembled, valves and fixture supply lines are reinstalled
or replaced if desired. The system is then thoroughly flushed from the
main line to each and every fixture. The work areas are cleaned and returned to
the pre-installaion state. Finally, a quality assurance inspection of each
connection and fixture is conducted by the lead technician.
