  • Abrasive Blasting Environmental Requirements
    NASSCO Environmental Instruction #1: Environmental Requirements for Abrasive Blasting Abrasive blasting operations are very closely regulated by the San Diego Air Pollution Control District. Since these operations are subject to strict local and federal laws, all abrasive blasting activities conducted at NASSCO are required to be carefully controlled at all times to ensure compliance. For questions about these or any other NASSCO environmental requirements, call 619-544-7506. Before You Begin NASSCO Approval Your company may not perform abrasive blasting at any NASSCO facility without first applying for and obtaining approval from the Environmental Engineering Department to conduct this activity. Separate approval must be obtained for each abrasive blasting job conducted (one per ship or location). To apply for approval, a completed and signed copy of “NASSCO Environmental Form #1: Request for Authorization to Perform Abrasive Blasting at NASSCO Facility” to the NASSCO Environmental Engineering Department at [email protected] or fax to 619-744-1088. You may not begin abrasive blasting until approval has been received from the Environmental Engineering Department. Permits Most abrasive blasting operations require an air pollution control permit. The San Diego Air Pollution Control District (SDAPCD) is the permitting agency for stationary and portable abrasive blasting operations operated solely within San Diego County. Alternatively, portable abrasive blasting operations can be registered with the California Air Resource Control Board (CARB) portable equipment registration program, which authorizes statewide operation of the equipment. Your company is responsible for obtaining and maintaining the appropriate permit or registration for your abrasive blasting, as required. For more information about San Diego County’s permitting program, contact SDAPCD at 858-586-2600, or visit www.sdapcd.org.

  • UHP WATERJETTING – the OLDEST - NEW METHOD for SURFACE PREPARATION Brady Deroche, Innovative Surface Prep Gray, Louisiana
    UHP WATERJETTING – THE OLDEST - NEW METHOD FOR SURFACE PREPARATION Brady DeRoche, Innovative Surface Prep Gray, Louisiana ABSTRACT With the growing concerns over change in Federal regulations, and the increase in waste disposal costs, the oil and gas maintenance industry is in need of an alternative solution to fit these specifications. They are in need of an innovative tactic that is controlled, safe, predictable, and most importantly, able to provide an ultra-clean surface that meets the set industry performance standards. Little do most people know, this solution we are all looking for was created in the early 1800s, and used by coal miners as a method to remove loose debris and coal. This solution is the use of water pressure to remove contaminants and various materials. The method has evolved since the early 1800s to now use ultra-high-pressure water to effectively remove coatings and contaminants from surfaces. The process is now known as UHP Waterjetting. In 1994, the US Navy embraced this method as a means to reduce waste streams, and provide a solution to ships breaking up at sea because of corrosion. Surface preparation techniques have evolved with the acceptance of UHP waterjetting (UHP WJ). The new technique has proven to provide benefits in not only workflow, but also in the overall project’s pocketbook as well. With quality requirements rising and budgets for maintenance activities decreasing, UHP WJ has become the ideal surface preparation solution. With abrasive users still hesitant to make the change to water, this paper aims to provide you with a wealth of knowledge surrounding the topic and more details on one popular method of utilizing this solution, remote controlled robotics.

  • Chloride Removal Using “Recyclable Encapsulated Abrasive Media”
    ____________________________________________________________________________________________TECHNICAL PAPER RE-PRINT Chloride Removal Using “Recyclable Encapsulated Abrasive Media” Michael Merritt, Sponge-Jet, Inc. From: The Power of Paint & Coatings; Conference Proceedings 2010 Phoenix, AZ ▪ February 7-10, 2010 Reprinted with Permission from The Society for Protective Coatings ____________________________________________________________________________________________ © 2010 SPONGE-JET, INC. CHLORIDE REMOVAL USING “RECYCLABLE ENCAPSULATED ABRASIVE MEDIA” Michael Merritt Sponge-Jet, Inc Portsmouth, NH USA ABSTRACT: This paper presents results of multiple test programs that have been performed to determine the effectiveness of recyclable encapsulated abrasive media to remove chlorides during surface preparation. Tests published in 2002 concluded that this technology consistently achieves significant reductions of chloride levels in comparison to those achieved with conventional abrasive blasting. However, those tests were conducted with new media and not recycled media; leaving questions regarding the effect of recycling and possible re-deposition of contaminates on the surface. Recent tests indicate that chloride removal can be efficiently performed while recycling encapsulated abrasive media and no detrimental effect on removal rates occurs with increased recycles; in fact, increased cycles showed a slight improvement in removal efficacy. Test results also indicate that blasting with encapsulated abrasive media can frequently reduce chloride concentrations to below typically specified levels. This process compares favorably in both cost and speed to other technologies, which often require a multi-step procedure such as abrasive blast, water or chemical wash and final abrasive blast to achieve specified levels of surface contaminants. BACKGROUND INFORMATION ON ENCAPSULATED ABRASIVE MEDIA Encapsulated Abrasive Media was invented in the late 80’s and has grown in use as an accepted form of abrasive blasting since that time.

  • What Effect Does Waterjet Cleaning Have on the Surface And
    2007 American WJTA Conference and Expo August 19-21, 2007 • Houston, Texas Paper WHAT EFFECT DOES WATERJET CLEANING HAVE ON THE SURFACE AND SURFACE PREPARATION? L. Frenzel Advisory Council San Marcos, Texas USA ABSTRACT This paper is a refresher on the effect that pressurized water has on the gross and microscopic details of a substrate. The paint and cleaning industry “knows” that waterjet cleaning doesn’t create an anchor “profile.” However, some industries, such as automotive engine parts, use a waterjet process to create the profile over which a hard coating is placed. The difference between a profile created by abrasive blast and the profile that is created, or cleaned, by waterjet will be examined. The effect on adhesion values will also be examined. Organized and Sponsored by the WaterJet Technology Association 1 INTRODUCTION The coatings and corrosion industries tend to learn by experience within a fairly closed network. Around 1977, when I first observed the effect of 140 MPa (20,000 psi) waterjet cleaning on new, old corroded, and painted steel surfaces, I didn’t know what I was seeing. The surface looked so different from those obtained by dry abrasive blast cleaning. I read all the papers that were published by the WaterJet Technology Association in the USA and the BHRA group in Europe and thought about the traditional surface as we think of it in the coatings industry. Many of the initial waterjet (WJ) papers were written by academicians. They were filled with equations and centered on cutting, not cleaning. The phenomenon of what happens to the surface when a droplet traveling at high velocity hits it is found in cavitation studies in the marine, rocket, and aircraft industry, but not in the coatings literature.
