Cooling
Water Piping Cleaning
 Maintaining
the supply and return piping associated with condenser and heat exchanger
operation is an important task. Piping system neglect can lead to
reduced cooling water flow capacity and damaging corrosive attack.
Associated costs include increased electrical power usage, decreased
component operating efficiency and, in  some
cases, multi-million-dollar piping system replacement. Hennigan Engineering
Co., Inc. has the experience and equipment necessary to restore flow
capacity and mitigate corrosion.
Innovations in the design of semi-automated high pressure rotary cleaning
nozzles enable Hennigan Engineering to custom build versatile cleaning
systems perfectly suited for the cleaning of any diameter cooling
water piping.
Traditional pipeline cleaning methods exhibit inherent drawbacks
 ranging
from poor results and low productivity levels to high cost and
environmental concerns. Even hydroblasting methods utilizing multiple,
stationary jets have produced unacceptable levels of "streaking".
Our state-of-the-art self-rotating cleaning nozzles can produce "white
metal" levels of cleanliness (when necessary) from even the most
highly fouled conditions, at pressures up to 20,000 psi.
Experienced Hennigan Engineering personnel can "dial in"
the optimal rotation and traverse speeds of our rotary cleaning
heads to allow for uniform, full surface coverage at high productivity
rates.
 Our
safe and effective methods offer non-manual, non chemical, removal
of tenacious scale deposits, corrosion build-up, failed coatings,
zebra mussels, marine molluscs, and MIC corrosion cells without
damaging pipeline base metal.
Special polymers, oxide inhibitors, and metal passifiers can be added
to the waterjet depending on job requirements. For more delicate jobs,
pressure and flow rates can be independently adjusted to gently remove
biofouling and marine growth, preserving valuable epoxy coatings and
rubber liners.
When safety, time and cost are high priority, Hennigan Engineering
offers the latest in effective cleaning solutions.
