Developments In Abrasive Blast Nozzle Technology: Reducing Noise Exposure While Preserving Nozzle Performance And Usability

Developments In Abrasive Blast Nozzle Technology: Reducing Noise Exposure While Preserving Nozzle Performance And Usability
Available for download

Abrasive blasting operations used for paint and surface coatings removal are essential for the maintenance of the ships, aircraft, and land vehicles of the United States Armed Forces as well as use industries such as oil & gas, power generation, construction, mining, and infrastructure, among others. Abrasive blasting nozzle design is rudimentary and noise levels produced during abrasive blasting operations in shipyards, maintenance facilities, and factories for removing paint and surface coatings often exceed exposure limits put in place by Occupational Safety and Health Administration (OSHA). Reducing a worker's occupational noise exposure is imperative from a safety and economics perspective.

The U.S. Centers for Disease Control (CDC) estimates that 1 in 3 adults suffer from hearing loss.  The U.S. National Institute for Occupational Safety and Health (NIOSH) further provides that 24% of U.S. workers hearing loss is caused by occupational exposure. To prevent hearing loss, the U.S. Occupational Safety and Health Administration (OSHA) recommends that workers not be exposed to sounds at or greater than 85 decibels (dBA) for 8 hours.  Abrasive blast nozzles, however, can produce noise levels upward of 115dBA, for which OSHA sets a max safe exposure time of just 15 minutes per day.

A life cycle cost assessment led to the selection of DSS for field gas gathering network composing of more than 200 miles of pipelines. Buried portions are provided with external coating. Furthermore, due to high chloride content in the soils, the external corrosion threat was mitigated through the use of an external coating supplemented with CP. 

As there was no industrial reference covering onshore DSS pipeline CP criteria, lab testing was conducted to establish the criteria and confirm if the risk of hydrogen embrittlement is managed appropriately. This is further evaluated with field data to confirm pipelines integrity.

It was requested that exposure testing be completed on various high durability coatings products to evaluate gloss retention and color changes. Various systems were chosen to test, some with clear coats and some without. They were placed in cyclic UV/condensation testing, concentrated natural sunlight testing in Arizona, and outdoor exposure testing in South Florida.
