What Does a FlashbackArrestor Do and How Is It Maintained?
When an explosive mixture of fuel gas and air or oxygen is present in a gas line upstream of a welding or cutting blowpipe, the flame can flash back into the gas line, posing a significant safety hazard
A flame or flashback arrestor is a safety device used to put out a fire As a result, it is utilised to avoid flashback into cylinders or piping A flashback arrestor is not the same as a non-return valve, which has no flame-stopping properties. A non-return valve can help to lessen the likelihood of a flashback by preventing the reverse flow of oxygen into fuel lines and fuel into oxygen lines
A flashback occurs when a flame burns back into the torch’s blowpipe and goes back into your gas cylinders via one of the gas lines. Flashback can, at least, burn the inside of your hose and cause damage over time It can also generate explosions that might hurt people, destroy property, and send dangerous substances into the environment
A flashback arrestor is a safety device that prevents a flame from returning to a gas cylinder or gas pipe by cooling or extinguishing the flame Flashback arrestor testing is one of the most important things to perform once every six months or twelve at least. This is to ensure the safety of everyone involved in the process as well as the people around the vicinity.
The Australian requirements for gas cylinder storage require flashback arrestors to be installed in accordance with AS4603 To guarantee that the arrestor is still working properly, flashback arrestor testing methods require arrestors to be tested or changed by a competent person at least once every 12 months.
Also, whenever a flashback occurs, the flashback arrestor, gas hose, and any fittings should be removed, inspected by a qualified person, and repaired or replaced as necessary. This is due to the fact that flashbacks might harm the arrestor and cause it to lose its effectiveness Any strange sounds (such as hissing) or cracking should also be reported, since your equipment may require an oxy acetylene leak test
Welding inspections also play a major role when it comes to welding maintenance. Weld inspection is the process of inspecting welds for quality, strength, safety, and a variety of other relevant characteristics
A weld inspection involves experienced professionals performing a series of quality assurance checks before, during, and after the welding process to ensure that the fabrication is as safe and secure as feasible.
Welds are utilised in many sectors and environments around the world, whether they are made of metal, thermoplastics, or another material entirely, and adequate inspection and care are critical to keeping both employees and civilians safe
Placement
Arrestors must be properly placed in order to successfully protect you in the event of a flashback Flashback arrestors should be installed at each gas line at the regulator output for hoses less than 3m in length, according to WorkSafe standards A flashback arrestor is required at the torch end of hoses longer than 3m.
In addition to the arrestor, the hose should have a non-return valve and a temperature actuated cut-off valve at the regulator end, and a non-return valve at the torch end. Some arrestors include all of these features; check with the maker to ensure you have all you need
Flashback arrestors must be tested following the production process according to Australia's oxy acetylene testing regulations They should also be tested - or changed - on a yearly basis by a qualified individual. In the event of a flashback, the arrestors must also be tested to determine whether any parts must be fixed, replaced, or discarded
Work Health and Safety has no set rules for expiration dates, so it's vital to double-check these dates with your manufacturer or supplier Check with your supplier about any additional storage or maintenance needs.
