Condenser Tube
Cleaning

Our
main focus is to restore and maintain maximum operating efficiency
for every condenser and heat exchanger we clean. Hennigan Engineering
Co., Inc. has the experience required to review your particular
conditions and employ the appropriate cleaning technique for every
application.
Given the job parameters, we successfully implement chemical cleaning,
mechanical cleaning (brushes, metal/plastic scrapers, abrasive balls)
and high pressure water jetting. Proper assessment of the conditions
affecting each power plant is crucial in choosing the correct course
of action.
We work closely with our clients to offer a comprehensive cleaning
solution, taking into account tube base metal compositions, base
metal conditions, corrosion control, fouling agent, scale composition,
cleaning window, safety and environmental concerns.
We rely heavily on the use of specialized high pressure water jetting
equipment to satisfy the majority of our project requirements. We
have custom designed our high pressure water jetting systems to
perform far beyond the capability of off-the-shelf equipment.
The net result is a package designed to provide complete 360 I.D.
tube cleaning without harming tube base metal. With operating pressures
ranging from 10,000 - 20,000 psi, we can effectively remove all
foreign debris, from biological films to calcium/silica scales.

Advantages of our
Hydrolasing technique:
- Cleans all tube materials without harm,
from brass through titanium
- Inhibits corrosion and extends tube life
by removing corrosive deposits from tube I.D. and tube
pits.
- Cleans any length and diameter of straight
or U-tube heat exchanger.
- Extends maximum operating efficiency by
removing fine layer of silt and organic debris which is
missed by mechanical cleaning and leads to rapid refouling.
- Removes any foreign scale deposit.
- Environmental Safety - No chemical discharges,
or hazardous waste removal.
- Custom designed cleaning nozzles which offer
full 360 I.D. cleaning without streaking tube.
- Multiple lance systems- up to 8 (or more)
operators for fast cleaning of large main condensers.
- Radiological Waste minimization with the
use of our positive shut off pressure control systems.
- Cost Effective - restored baseline performance
and extended refouling rates; promptly recovers job expense
(in exponential fashion).
