Heat
Exchanger 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 ofspecialized 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.
- Proven compliance with NRC - Generic letter
89-13.
- Cost Effective - restored baseline performance
and extended refouling rates, promptly recovers job expense
(in exponential fashion).
