BHR Group 2016 23rd International Conference on Waterjetting
The WJTA-IMCA exhibition in New Orleans is over for 2016. I missed a good exhibition and round-table of practical talks and a chance to mingle with colleagues. However, I was preparing for the BHR Group Waterjetting 2016 conference in Seattle on Nov 15-18. This BHR group conference is typically held in Europe so it …

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 …

Comparison of Wet Abrasive Blast (WAB) and Dry Abrasive Blast Cleaning
There are many methods of wet abrasive blast cleaning (WAB) in surface preparation to remove coatings. Since the 1980’s, Carolina Equipment and Supply Co. (CESCO) has been supplying WAB equipment along with recycling methods. Recently CESCO sent me two youtubes to directly compare traditional dry abrasive blast cleaning and Wet Abrasive Blast Cleaning using their …

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 …
