We are delighted to announce that our nozzles received FM-approvals in 2020, among which are selectable gallonage nozzles, constant gallonage nozzles, and multiple purpose nozzles. Major differences among these three types of nozzles are described in detail as follows:
It took us about a year of hard work to receive the certifications, but it’s worth it. “No pain, no gain” explains it well. We’d like to share with you the hardship and difficulties we’ve gone through so that you can get yourselves better prepared in advance.
To begin with, the nozzle is a tool for firefighters to connect fire hose before fires can be successfully put out. Therefore, it is also considered a very important firefighting gear. A certified nozzle in good quality ensures that the firefighters put out fires as professionally as they can.
- Make sure that the water sprays form perfect concentric circles without any flaws to prove the nozzle’s water spray quality. Flawed shapes could have a negative impact on the fire-extinguishing efficiency.
- The nozzle that is tested will be put under pressure at 1000 psi to ensure its high pressure durability, which means the nozzle can still function well under pressure higher than normal.
- The nozzle will be exposed to a temperature at 57 degrees Celsius for 24 hours to ensure that it operates normally after prolonged exposure to sunlight.
- The low-temperature testing is conducted immediately after the high-temperature testing, during which the nozzle will be exposed to a temperature at -40 degrees Celsius for 24 hours to ensure that it operates normally even in the polar regions.
- Rough test follows temperature tests immediately, during which the nozzle will be dropped to the ground from a certain height to ensure that it operates normally after it lands. Firefighters drop their gears, accidentally or not, quite often, so the rough test is a must.
- The nozzle also undergoes corrosion test to ensure that water left inside won’t rust away because all its parts are made of metal. Every firefighter needs at least one corrosion-resistant nozzle.
- In addition, the non-metallic parts are required to undergo certain testing to ensure the nozzle’s inner parts are in good quality. Even a small crack in any of the inner parts will cause a nozzle to leak, which influences the nozzle’s normal water flow.
In conclusion, earning certifications is a tough row to hoe, which takes tremendous time, money, and energy. To provide our customers with quality products, we made it after all. Please click on the link below to view the UL/FM certificates we’ve earned:
