Model 6A00 TECHNICAL BULLETIN 6A00 - TB Inline Deflagration Flame Arrestor

Transcription

1 TECHNICAL BULLETIN 6A00 - TB 0-7 ISO Registered Company Model 6A00 Inline Deflagration Flame Arrestor OBJECTIVE The Model 6A00 inline deflagration flame arrestor is a device that can be fitted to the opening of an enclosure or to the connecting pipe work of a system of enclosures. Its primary function is to allow the flow of gases or vapor of flammable liquids through the enclosure, but prevent the transmission of a flame. The element inside the housing provides an extinguishing barrier to the ignited vapor mixture by absorbing heat from the flame. The Model 6A00 is used as an independent safety system to ensure explosion protection. TECHNIQUE 6A00 flame arrestors are designed on the principle of "quenching gap". The crimped SST metal element allows vapor to pass through in order to allow a vessel to breath, yet prevents the propagation of a flame from the exposed side to the protected side. CONSTRUCTION Housing Material: Carbon Steel, Stainless Steel. Trim Material: Stainless Steel (.457) element. Standard element is suitable for explosion group IIA, IIA, IIB, IIB3, IIB and IIC flammable gases and vapors. Elements for other gas groups are available upon request. SPECIAL FEATURES The Model 6A00 is designed, manufactured, and tested according to Directive 204/34/EU (ATEX4) and ISO The single element design is bidirectional and available for horizontal or vertical installations. The maximum distance between flame arrestor and ignition source should not be more than 50 x the diameter of the connection size for most hydrocarbon gases. Easy Maintenance: The Model 6A00 deflagration flame arrestor is a passive device with no moving parts. The flame cell element can be easily removed for inspection and cleaning in appropriate solvent solution. Sizes: Units are available in DN20, 25, 32, 40, 50, 65, 80, 00, 25, 50, 200, 250, 300 (3/4", ", -/4", -/2", 2", 2-/2", 3", 4", 5", 6", 8", 0", 2") line sizes; thread connections according to ISO7/, BS2 or ASME B.20.. Standard for flange connections to EN092- PN0, ASME B6.5 50#RF or JIS B K.
