Cylinders Flashback Arestors

IBEDA offers dry-type flashback arrestors (FBA) with flame barriers, gas non-return valves (check valves), thermal shut-off valves and pressure-sensitive cut-off valves. The flashback arrestors SRT, DGN, DG91N and DEMAX have the safety features of a flame barrier, gas non-return valve (check valve) and a thermal shut-off valve, thus meeting the requirements of a flashback arrester described in EN 730-1/ ISO 5175. DEMAX is a dry-type high flow flashback arrestor (FBA) that uses several DGNs in parallel connection to give users a higher gas flow.

The models SR, DG, and DG91 have two built-in safety functions: a flame barrier and a non-return valve (check valve). The integrated flame barrier extinguishes the flashbacks and protects the valve to make sure it works safely even after a flashback. IBEDA offers flashback arrestors (FBA) for many industrial gases (Fuel Gases) such as acetylene, hydrogen, methane, natural gas, propane, propylene, butane, as well as oxygen and compressed air.

Resettable Flashback Arrestors

IBEDA offers resettable flash arrestors with flame barriers, thermal shut-off valves, gas non-return valves (check valves) and pressure-sensitive cut-off valves. The resettable flashback arrestors DS1000 and DS2000 have the safety features of a flame barrier, a thermal shut-off valve, a gas non-return valve (check valve), and a pressure-sensitive cut-off valve thus meeting the requirements of a flash arrester described in EN 730-1 / ISO 5175. The pressure-sensitive cut-off valve stops the gas flow in the case of a pressure shock.

The thermal shut-off valve stops the gas flow in the case of a hose burn back. The integrated flame barrier extinguishes the flashbacks and protects the valve to make sure it works safely even after a flashback. In order to continue working the user has to look for the cause of the flashback. Once the problem is corrected, the safety device is reset and work can be continued. IBEDA offers resettable flash arrestors for many industrial gases (fuel gases) such as acetylene, hydrogen, methane, natural gas, propane, propylene, butane, as well as oxygen and compressed air.

Safety device for torch or point of use (cutting machines) EN 730-1 / ISO 5175

IBEDA offers flashback arresters with flame barriers and gas non-return valves (check valves). The flashback arresters GG, GT, TT and DG91UA are torch or point of use (i.e. cutting machines) flashback arresters that have the safety features of a flame barrier and a gas non-return valve (check valve), thus meeting the requirements of a flashback arrester described in EN 730-1 / ISO 5175.

The integrated flame barrier extinguishes the flashbacks and protects the valve to make sure it works safely even after a flashback. The flashback arrester model TT is a barb connection that installs a reverse flow check valve and flashback arrester in welding hose. The torch mounted or hose mounted flashback arresters prevent hazardous gas mixtures from harming the user. IBEDA offers flashback arresters for many industrial gases (Fuel gases) such as acetylene, hydrogen, methane, natural gas, propane, propylene, butane, as well as oxygen and compressed air.

Gas Safety Devices with Check Valves for Laboratories

IBEDA supplies safety for every application. The A-size flashback arrestor types MGG and MDG with Check Valves are used with miniature-welding and -cutting tools. These A-size flashback arrestors are especially characterised by their small size and the low weight.

IBEDA offers flashback arresters for many industrial gases (Fuel gases) such as acetylene, hydrogen, methane, natural gas, propane, propylene, butane, as well as oxygen and compressed air.

Stainless steel flashback arrestors for pure gas applications

In addition to the already established DG91N-VA, there are three new flashback arrestor types available now which are suitable for pure gas applications: DEMAX-VA, DGN-VA and ESF-VA – providing maximum safety and functionality. With these products you are now even more flexible in areas that impose particularly high demands to the material and the environment.

Safety devices cu cuplaj rapid (EN 730-1 and ISO 5175)

The types DGNDK, DKST, DKSG and GDK with DKT combine maximum safety which is proven millions of times with the advantages of worldwide standardised couplings within the welding industry.

Flashback arrestors for gas manifolds

IBEDA safety devices for manifolds and bundle batteries are manufactured to the latest standards. All safety elements of the safety devices, from the high pressure non-return valves, the automatic quick-action shut-off valves to the safety devices with multiple function (decomposition arrestors) are design-type tested according to the latest standards (EN 730-1 and EN 15615) and are suitable for all ranges of capacity.

Gas quick-action couplings (hosecouplings)
Gas hose couplings (quick connectors) for fuel gases, inert gases and Oxygen
IBEDA as a leading manufacturer offers a wide product range of quick-action couplings gas (hose couplings). The quick-action couplings gas is Used for the installation and maintenance in various different fields of industry and handicraft. The quick-action couplings IBEDA gas is quick and easy to install on torches Without Using Any tool, and CAN BE Used for the simple extension of hoses. The quick-action couplings gas (quick connectors) is designed for and in Cooperation with the industry and has strong and durable Their characterised by design. Design-type tests and special tests by the voluntary Federal Institute for Materials Research and Testing (BAM) PROVE the outstanding quality of the IBEDA Manufactured couplings. IBEDA gas hose couplings (quick connectors) is Suitable for most technical gases (fuel gases) Such as Acetylene, Hydrogen, Ethen, Propane and Butane as well as inert gases and Oxygen.

Flashback arrestor testing equipment (EN 730-1 and ISO 5175)

by a qualified and authorised person every year (depending on the country specific regulations). Without changing of the position, flow rate comparison checks can be made. Additionally, the function of the pressure-sensitive valve can be checked. This equipment allows flow rates to be measured as well as testing the function of the pressure sensitive valve (flashback arrestor types DS1000, DS2000).

Flashbacks and dust particles <100µm can lead to the flame arrestor becoming clogged with the times resulting in a decreasing flow rate. Furthermore, small dirt particles can impair the gas non-return valve.
