Flame arrestors are commonly constructed of fine metallic conductors installed within tubular members that serve to absorb heat from the flame front, lowering the temperature below the ignition point, and then dissipating it harmlessly through the housing to the atmosphere.
"The testing of flame arrestors using an explosion chamber, where the UUT is located outside of the chamber, is an innovative application," Mr.
Using the crack arrestors saved several million dollars over pipe replacement and was a key issue in the economic justification of the conversion.
When fracture toughness criterion is used, control can be achieved by ensuring that the pipe has adequate ductility either by specifying adequate toughness or installing crack arrestors on the pipeline to stop propagation.
PETRONET discussed the requirements of fracture control devices with ASME and a decision was made to base the distance between arrestors on Class Location: Table 1.
Based on this use rate, 238 arrestors would be required to operate the pipeline at 49 bar (711 psi).
The toughness properties could not definitively preclude the use of crack arrestors.
The cost to replace significant sections of pipe would make the economics unjustifiable so the cost of crack arrestors became critical.
Some of the prominent trends that the market is witnessing include rapid growth of manufacturing sector, introduction of flame arrestors with low-pressure drop and high flow performance and growing popularity of combined deflagration and detonation flame arrestors.
