The World’s Quietest Blast Nozzles
Snakebite XQ saves ExxonMobil unprecedented asset downtime
• 45% Less Thrust!
As one of the world’s largest publicly traded energy providers and chemical manufacturers, ExxonMobil develops and applies next-generation technologies to help safely and responsibly meet the world’s growing needs for energy and high-quality chemical products.
ExxonMobil, a global refinery, was stuck looking for solutions to ensure they complied to the latest OSHA noise exposure regulations and needed to lower the overall dB level while abrasive blasting. Current OSHA regulations only allow operators to blast for a limited time at standard noise exposure limits. The impact of implementing this time restriction would have meant blasters would have to cut back their daily blasting hours from 6.5 to 5, which would have blown out job timelines, or drastically increase the cost of completing the projects with more workers.
“The implication of the new regulations would have drastically blown out timelines. I was standing outside the tank and all I could hear was the compressor. I peeked my head in to see when the blasting would start… and it already had.”
– Eric, ExxonMobil Chief Industrial Hygienist
BlastOne’s Snakebite XQ blast nozzle tests were conducted using GMA ToughBlast Garnet and maintaining between a range of 85 to 110psi. Through extensive trials the XQ delivered a fantastic 90% reduction in noise levels.
|Blast Nozzle Used||At Blaster||25ft from Blaster|
|Regular Tungsten Carbide #7 Blast Nozzle||122.3 dBA||109.8 dBA|
|SnakebiteXQ #7 Silenced Blast Nozzle||101.9 dBA||91.8 dBA|
|Sound Reduction Recorded||20.4 dBA||18 dBA|
With the introduction of the SnakebiteXQ ExxonMobil no longer needs to monitor for extra noise exposure when blasting. Additionally, other trades can work in the same vicinity as the blasting contractor without wearing heavy hearing protection. Using GMA ToughBlast Garnet they now can also blast faster, use less abrasive with no heavy metal concerns, and save money.
The SnakeBite XQ redues noise generated by up to 16 dBA – that’s equivalent to up to 75% quieter than standard nozzles, and the typical high pitched screech is now gone.
With its reduced noise capabilities, SnakeBite XQ allows other crews to work in the vicinity of blasting, minimizing production disruptions
EASE OF USE
The unique design of nozzle and silencer reduces operator fatigue by up to 45%. Operators can better maneuver the nozzle and will be less fatigued over the shift.
SNAKEBITE XQ – WATCH AS IT’S PUT TO THE TESTRecently, BlastOne launched it’s most innovative product to date – The Snakebite XQ – which we claim to be the world’s quietest abrasive blasting nozzle.That’s a pretty substantial claim and so we’d like to demonstrate how we can defend such a claim.UNDERSTANDING NOISE VOLUME (DECIBEL LEVELS)How loud is 1 decibel?Volume is not measured on a linear scale like our base-10 number values where “20” is twice as much as “10”. When it comes to decibel levels, “20dB” is ten times louder than “10dB”. That’s because decibel volume is measured on a logarithmic scale – which can be very confusing.USEFUL COMPARISONS:10 dB ………………….. Breathing
20 dB ………………….. Whisper, rustling leaves
30 dB ………………….. Quiet rural area
40 dB ………………….. Library background noise
50 dB ………………….. Conversation at home
60 dB ………………….. Conversation in restaurant public area
110-120 dB…………… Abrasive blast nozzle at 100psiWhat’s the value of 10 dB?
OUR TESTING TRIAL (SEE VIDEO)
Here are our readings:
COMPARING SNAKEBITE TO THE OTHER TWO NOZZLES
5 ft (approx 1 metre)
25 ft (approx 7.5 metres)
50 ft (approx 15 metres)
Adjusting these factors will have an effect on dB reduction.
