Comparison of WaterJet and Abrasive Blast Coatings Removal

Here is a posting of a comparison video of UHP WJ coatings removal (hydroblast, waterjetting) with dry abrasive blast cleaning. (AB) It is the smallest particles which drift from the site, that you never see, which causes lung damage. One of the abrasive blast sites was in an 1850’s california village. few precautions were taken …

Microscopic Analysis of Steel after Waterjet Cleaning

In the late 1990’s,  I received a report from Materials Evaluation Laboratory.  The report is copyrighted.  The pump company had cleaned UHP WJ on panels supplied by a major oil company.  Materials Evaluation Laboratory analyzed the substrate with microscopy and metallurgy compared to abrasive blasting.  This was at the time that UHP WJ was scarce and …

Quality of Water for Use in High Pressure Pumps

For 30 years, I have received questions about the quality of water that should be used for removal of coatings. How much dissolved material or minerals gets left on the surface? Just recently after an hour long webinar to 200 people, the questions was “What shoul the quality of the water be?” Among the first …

Surface Preparation- Why surfaces with more surface area look darker.

Surface Appearance with Surface Area. Back in the early 80’s, Dr. Lydia Frenzel and myself took a series of water-jet processed steel panels and examined them with a scanning electron microscope. We were hoping to receive confirmation of what our computer models told us; that is, water jetting at or above a threshold pressure produced …

Lead Based Paint on Bridges- Cost Effective Alternatives- FHWA

I get questions about relative cost for various surface preparation methods and the pros and cons.  I refer people to this study as they can plug in their own numbers. “COST EFFECTIVE ALTERNATIVE METHODS FOR STEEL BRIDGE PAINT SYSTEM MAINTENANCE” CONTRACT NO. DTFH61-97-C-00026 was published by the FHWA with Corrpro in September 2001.  The final …
