Do all flame barriers provide the same level of protection?
No. Not all flame barriers are created equal. Flame barriers can be make of different materials and have different micron openings. The flame barrier needs to be a material that will extinguish fires and have the right size openings to allow gas through - but not a flashback. If the micron openings are too large or the material is not suited to the job - the flame barrier will not stop a flashback. SuperFlash flashback arrestors are made of high quality 3-5 micron stainless steel, and are 100% tested so they stop flashbacks every time.
How safe are your flashback arrestors?
A quality flashback arrestor should have a stainless steel flame barrier and low porosity. (The flame barrier is the part of the flashback arrestor that actually stops the flashback.) Low cost or discount flashback arrestors often use a barrier made of bronze and with a porosity that can be as high as 20-40 microns. This allows the manufacturer to save money, but can put the user in danger because bronze is an alloy containing a large portion of copper.
SuperFlash flashback arrestors use a flame barrier with a porosity of 3-5 microns, enabling them to safely stop flashbacks.
Won't a check valve stop a flashback?
Check valves only prevent the reverse flow of gases, and CANNOT stop a flashback. Check valves do not have the essential element to stop a flashback - a flame barrier. A flame barrier stops the rapid flame propagation through hoses, regulators, and torches. Without this protection, the check valve cannot stop a flashback.
Using soap and water for leak testing is not only dangerous, but the residue it leaves behind can also corrode or damage the cylinder valve. SuperFlash's Leak Test Solution leaves no residue, and meets MIL Spec PRF-25567E.
