It is well known that ships are extremely large in size, stretching for hundreds of meters, and are extremely complex steel structures. It is impossible to be completely completed by robots on the assembly line like cars. Strong on-site assembly and repair capability. Moreover, a large number of work sites occur in shipyards, docks, and […]

The FRB series flashback arrestor is a safety device series designed specifically for industrial gas systems (acetylene and propane). Its core function is to prevent flames or high-temperature gases from flowing back (i.e. “flashback”) into the pressure regulator and upstream gas supply system, thereby avoiding explosion accidents. What is the FRB series backfire preventer for

Prevent welding flashback Oxyacetylene torch has been used for cutting, welding, brazing, and heating of metals for many years. The devices used today are safe, but every year hundreds of employees are injured or killed due to improper use. Wrong ignition/shutdown sequence, overheating caused by the nozzle being too close to the workpiece, etc. Knowledge

Avoiding “flashback”: deadly counterattacks and comprehensive defense strategies in welding and cutting operations. Behind the scorching stage of welding and gas cutting operations lies a momentary but devastating threat – tempering. It is not an ordinary flame, but a catastrophic phenomenon of mixed gases burning in reverse inside hoses or equipment, often accompanied by sharp
