Hydrogen flash back arrestor/ Oxyhydrogen flash back arrestor/ flash back arrestor for torch/ gas flash back arrestor
Hydrogen flash back arrestor/oxyhydrogen flash back arrestor
Hydrogen flash back arrestor adopts the domestic advanced high technology nano ceramics flash back
arrestor tube to take the measure of dry type flash back arrestor, it can flame out the backfire safely for the
hydrogen tube and can continue to fire up to work. It is a ideal safe device for using hydrogen to work at present.
The flash back arrestor applies in welding, cutting and other similar workplaces to protect the operators' safety. It also can be applied in oxyhydrogen gas tube to be a safety device for keeping it from back-fire.
Compared with other domestic and overseas similar products, the flash back arrestor has a stable structure,
light weight, good appearance, safe and reliable performance and other features. All kinds of technical index
have been tested according to the standard advanced requirements and experiment methods of domestic andoverseas similar products, and all the products have got access to delivery after pasted factory test.
1. Main technical parameter of flash back arrestor
Working medium: oxyhydrogen gas, hydrogen gas, acetylene and so on.
Opening voltage: 0.005MPA (0.05Kg.f/cm2)
Flux: >1m3/h
Flameout function: be able to fire off the reverse flow back-fire continuously
2.Model of flash back arrestor
FA11:either ends is M16*1.5 standard screw thread, apply in connecting with metal pipe or cylinder pressure
reducing valve.
FA-14: either ends are leather hose joint (8), to install in the leather hose.
FA-15: either ends are leather hose joint (5), to install in the leather hose.
3. Notice
1) The arrow mark on the flash back arrestor refers to the direction of airflow under the normal work. You
shouldn't install it reversely, otherwise the gas cannot pass through. You should check the joint whether there is any gas leakage.
2) The flash back arrestor is forbidden to be opened. Once it is opened, you must do the efficiency test again. Qualified ones need to present the conformity certificate again, or it cannot be installed to use.
3) Once the flash back have any damage, you must stop to use immediately and renew it to continue to use.
The flash back arrestor must force to be replaced after using for half a year.
4) You must do the inspection by using the qualified efficiency test equipment when examining and repairing
the flash back arrestor, qualified ones need to present the conformity certificate again. If you haven't
specialized efficiency test equipment, you need to replace the flash back arrestor instead of repairing.
5) The factory package should be placed in a dry and ventilated place, the flash back arrestor is forbidden to
touch anything smeary and corrosive. Do not throw it heavily or the flash back arrestor will be damaged.
