Flash Back Arrestors

For Gas Welding / Cutting Installation
ESAB has an enviable record in the important area of welding and cutting safety, having pioneered the introduction of Flashback Arrestors in India.

ESAB PROTEX

ESAB PROTEX is the flashback Arrestors designed to eliminate explosion or fire caused by flashback. The flashback Arrestor fits perfectly on regular outlet. It is fitted with a large capacity filter that allows unrestricted fitted flow gas flow during normal operations.

 

In view of the fact that flashback can occur in any of the cylinders ESAB PROTEX comes in two versions.

  • PROTEX - RO (For Oxygen)
  • PROTEX - RA (For Acetylene)

ESAB FR - 63

An extra security FR - 63 Flashback Arrestors should be mounted on the pipes at all Acetylene gas central installations. It is designed to arrest the flame and cut off further flow of gas. In case the flame is not arrested (quenched), the temperature will rise inside the Arrestor melting the soft soldering. A spring-loaded valve will then close the outlet and further supply of Acetylene will stop.

  • Working pressure : 1.5 bar
  • Mounting : FR - 63 is always mounted directly behind central regular and in the service line at the point of entry to each locality. Both at the inlet and outlet a BSP 1.5" pipe coupling is provided to make fitting and removal is easier.
