Piping components » Flame arrestors

Other Piping components:

During the tank filling, the breathing valve expel over the tank some gas that could burn.

The tank has to be protected to avoid that the flames spread inside the tank. This is the reason why a flame stopper is installed between the tank and the breathing valve and it has to:

» defeat the flame

» resist to make the hot fade way

» resist to the shock wave producer by an external explosion

Spectacle flanges Special industrial silencers Flame arrestors Sample coolers & sample boxes

The flame arrestor efficiency is reduced by the flame arrestor element and by the fifth that is inside it. Considering all these things. CDB ENGINEERING produce flame arrestor element only in SS316 and is easy to disassemble for a frequent maintenance.

 

The flame stopper CDB ENGINEERING can be also manufactured in cast body and there are many different type as:

standard flame arrestor from 2" to 12" used for breathing valve assembly or free breath.

Box flame arrestor from 2" to 6" is used for the assembly of breath valve with convoyed breath or on the final part of pipe.

The flame arrestor element can be slipped removing the cover from the box an the arrestor. CDB ENGINEERING is also able to manufacture flame arrestor with welded body and are available made of the following material: body built with a diameter reduction in A 105N or with a diameter reductions in WP304L or 316L and flange in F304L or 316L from 2" to 12".

Body and flame arrestor element built with a plate in SS316L THK 3MM. Sliding flange in S.S.316L from 2" to 6". Body and flame arrestor in S.S. 316L THK 3MM, fixed flanges in SS316L from 2" to 6".
