Pipe and Tank Cleaning

Maintaining the supply and return piping associatedwith 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 enables 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.
