Gas seals - Import export

In parallel with activities related to covering, Hannecard has also built up a solid basis of expertise in the field of extruded profiles and technical molded articles. Its experience in hand fabrication and the molding of rubber and polyurethane items enables Hannecard to provide custom-made, high added-value elastomer parts for many industries. Hannecard’s customers are highly diverse, and come from sectors including maritime and nuclear; mining and extraction; energy, oil and gas; seals and machinery; and the metal and chemical industries, among others. Working in close cooperation with you, Hannecard’s technicians can create the precise extruded profile or molded parts that you need, based on the dimensions and specifications you provide. We are always eager to help you select exactly the right type of elastomer, and our team of experienced professionals are on hand for dedicated follow-up for your project.

Europem can supply complete flare systems which include knock-out vessels, water seals, molecular seals, conical purge gas seals, pilots and ignition systems. Additionally, Europem has developed a unique ATEX zone O vapour extraction system for use in conjunction with VRU’s, combustors, flares and thermal oxidisers. Vessels Europem supplies the upstream equipment to remove droplets from gases or provide a seal between the flare burner and the waste gas piping in order to prevent air from infiltrating the flare riser and thus prevent flash back. Purge gas is employed to prevent flash back by stopping air ingress to the flare gas header. Molecular seals and also Conical seals are both devices that reduce purge gas flow rates. Conical seals will require a slightly higher purge gas flow rate than a Molecular seal, but have the advantage of a simpler more economic design. This design cannot be blocked by debris, sludge or ice formation and does not put additional load on the flare structure, being integral to the flare riser. Although purge systems are the perfect solution for flash back prevention, the flow of purge gas can always be lost. A water seal can be installed to provide the ultimate barrier to flame propagation upstream in the waste gas piping. Vessels can be supplied either as an integral part of a flare system or as stand alone items. Both vertical, typically integrated with the Flare riser, or horizontal configurations are available. Features Water Seal Vessels equipped with an overflow weir to maintain a minimum water level, anti-pulsation baffles and a dip-pipe with distribution cone forcing the waste gas to flow through the water bath. Molecular Seals are equipped with a riser pipe and cap to either form a layer of purge gas on the top, when the purge gas is lighter than the air, or on the bottom when the purge gas is heavier than the air of the vessel Conical Seals are in fact an inverted conical restriction made as a section of the riser. This restriction will locally induce a higher waste gas velocity which in turn entrains any penetrating air and carries it up to the flare burner. Knock Out Drums contain packing to separate droplets from the waste gas. A liquid level control with automatic purging prevents the vessel from overfilling.

Gas regulated recombination sealed batteries with valve . Maximum safety without maintenance with special acid pack with a kit for filling, enabling the acid to be introduced without any accidental spillage and with the guarantee of equal filling for all the cells. Great ignition power and limited auto-power loss. The use of Pb/Ca plates guarantees an increase in performance and life cycles greater than standard batteries. The AGM separator allows the complete absorption of the acid thereby avoiding hazards of leakage of electrolyte due to tilting or accidental dropping. The poly-propylene monoblock protects the plates from any knocks and external stress.
