- Sealing underground pipelines and other enclosed systems
ADVANTAGES:
- Portable
- Works past bends and junctions
- Includes leakage measuring capability
ABSTRACT:
Mark Modera and Francois Remi Carrie from Berkeley National Laboratory have developed a rapid,
economical technique to seal duct and other enclosed systems by
means of an internally injected aerosol. Berkeley National Laboratory's
aerosol compound seals holes in enclosed systems and is effective
even after bends and junctions. A unique, in situ aerosol
sealing apparatus, also designed and built at Berkeley National
Laboratory, delivers the new sealing aerosol. This multifunctional
field apparatus, designed to be portable and easy to use, is powered
by two, household circuits (15A/110V) and does not require the use
of desiccants. In addition to performing the sealing process, Berkeley
National Laboratory's compact field apparatus also measures leakage
of the system before and after sealing, eliminating the need to
invest in and field additional equipment. A description of the clog-free
atomizing and spray drying nozzle specially designed for use with
this technology is referenced below.
