Operation
Flame Arrestors, detonation flame arrestors, detonation arrestors, flame detonation arrestors stop the propagation of a flame by absorbing and dissipating heat through the large surface area of the bank sheets. Ignited vapour attempting to pass through the arrestor is forced through small passages within the bank assembly. Heat is absorbed, lowering the temperature of the gas below its ignition point and quenching the flame. Flame Arresters are typically used in the chemical, petrochemical and pharmaceutical industries on applications such as storage tank facilities, flare stacks, incineration systems, storage tank roofs or digester convertor to prevent the propagation of confined and unconfined delfagrations. Detonation flame Arresters additionally stop the high pressures and velocities that can result in detonations. Incase of ignition of vapours they burn harmlessly at the flame arrestor, preventing ignition of vapours in the tank and subsequent explosion.

Design Features
The main benefits of the 'Fuidyne Atmos®. detonation flame Arrestor, flame arrestors, detonation arrestors, flame detonation arrestors are derived from ifs unique element design. The large channel openings provide excellent pressure drop to flow and enhanced flow characteristics often resulting in reducing overall size and cost of both Flame arrestor and piping. In addition to this the less restrictive nature of the larger channel openings result in less clogging and easier cleaning - both important maintenance considerations. Finally the element enables higher operating pressures to be achieved. The 'Fluidyne Atmos®' Flame Arrestor after extensive research has been certified and type tested by FCRI, B.V. and other government agencies, and has also received the most stringent approval for Flame Arrestors, incorporating extended burn time performance, and have acceptance with B.P.C.L, I.O.C.L, H.P.C.L, L & T , REL , RIL & B.H.E.L., and many chemical, pharmaceutical , power industries and petrochemical industries.

Configuration
'Fluidyne Atmos®' Flame Arrestors are available for all common gas groupings to IEC or NEC codes, and supplied in range of sizes/materials/options; Net Free Area - three to four times, Bank Assembly - estensible and removable. Special "off-set" housing design is not affected by condensate accumulation, even when installed in horizontal piping. The result is minimal pressure drop, increased flow capacity and heat dissipation. Ordering information given below

Emergency & Conservation Vents

Emergency And Conservation Vents
Ask for Price

FLUIDYNE API 2000 Code EMERGENCY VENTS are designed to provide emergency pressure relief for storage tanks when exposed to overpressures that are not handled by standard tank vents. These vents provide the capacity to meet API standard 2000 for emergency venting due to fire exposure when properly sized. These covers also provide quick easy access for tank inspection and maintenance and provides pressure and vacuum relief . Vacuum relief must be achieved by special spring loaded venting devices attachment in such emergency pressure and vacuum relief vent covers. When excessive pressure builds within the storage tank the FLUIDYNE series emergency pressure relief vent begin to open at a predetermined set pressure relieving excessive pressure. When the overpressure has dissipated the cover reseat onto the base. FLUIDYNE emergency vents are available in several materials that are corrosion resistant to most petroleum product applications. The setting range is from a minimum of 50mm W.C to a maximum of 700mmW.C. Sizes are 400, 450, 500 and 600mm with flange drilling according to ANSI 150lb or API650





Vent And Fill Caps

Vent And Fill Caps
Ask for Price

Our vents and fill caps are specially designed to hold a constant tank pressure, reducing evaporation loss, contamination intake, over expansion, and contraction of the tank. These caps are generally used for above ground storage and tanks holding gasoline or diesel. Additional elements can be mounted on top of the filler cap for specific operational purposes.





Gauge Hatch

Gauge Hatch
Ask for Price

Made of quality material and components, our gauge hatch is used for controlling evaporation process and for dip measurement or for sampling purpose. Placed on the top of the tank, these hatches can easily be opened by pressing the latch with hand or foot. Our range of Gauge hatch is provided with bleeder attachment that makes it possible to relief pressure before opening the tank.

APPLICATION :
FLUIDYNE range of gauge hatches allow easy access to atmospheric liquid storage tank for manual level
measurement (dipping), temperature measurement and sampling.
BENEFITS :
* Robust construction to cope with regular use.
* Range of size and materials to suit a wide range of application.
* Non-sparking feature, provide by the use of Nitrile rubber or PTFE insert.
* The cover is designed with a condensation rim. This encourages liquid drainage    form the surface to reduce the possibility of freezing.
* Lockable handle and gas tight seal to 2.5 psig.
PRINCIPLE OF OPERATION :
Provides tank access where manual level gauging, temperature measurement or sampling is required the safety pedal allows the operator to open the gauge hatch whilst remaining 'hand free' to carry out required measuring.

Fluidyne Excess Flow Check Valve (MODEL : EFCV-100)



FLUIDYNE Excess Flow Check Valve also called FLUIDYNE Burst Control Valve or FLUIDYNE Hose Safety Check Valve or FLUIDYNE Velocity Check Valve. The valve has a sliding poppet within a chamber with an orifice at one end, wherein the closing flow rate settings can be adjusted. Precise adjustments can be made externally by turning an adjustment nut against a threaded screw extending at the end of the valve which causes a poppet to move within the chamber. As the poppet is urged toward the retainer by a coiled spring, the poppet is moved longitudinally within the chamber, either toward or away from the orifice. Turning the threaded nut enables to adjust the tension on the spring and therefore, the threshold flow rate of the valve could be precisely set. The valves operate by using the pressure differential across the valve to operate the poppet and spring assembly. The pressure differential is directly related to the flow of (SCFM) through the valve. When the pressure differential is within the operating limits - below the cutoff flow - of the unit, the force on the valve exerted by the spring is greater than that caused by the pressure differential the valve remains open and normal operation continues. When the pressure differential is above the cutoff limit, the force on the valve poppet exerted by the pressure differential is greater than the force exerted by the spring, and the valve closes. After the repairs to the line are made, normal operation is automatically enabled when pressure across the valve equalizes through the bleeder hole. The valve spring size can be specified by determining the air flow during normal operation and by estimating the flow if a failure or rupture occurs. FLUIDYNE Excess Flow Check Valve is used in filling lines and protects the system against excess flow rates and safely shuts off the flow due to hose bursts or excessive leakages downstream of the valve. FLUIDYNE Excess Flow check Valves are available in Standard Sandwich types suitable for mounting between a pair of flanges and also flanged screwed or butt weld connections types as per client requirements.
