In heat exchanger equipment, flanges and bolts tend to expand and contract. The com-pressive force is typically increased to counteract the effects. In order to fulfill these demands Betech has a range of gaskets available depending on the specific temperature, medium and pressure.

Flange Rescue Gasket (FRG)The Flange Rescue Gasket (FRG) enables bolted joints to be easily and effectively sealed to prevent internal corrosion. The soft modified PTFE inner ring of the FRG conforms seamlessly to the flange face, even if already damaged.

With FRG you obtain several benefits:• Timesavingandlesslostproduction• Majorcostsavingwhencomparedwithreplacing

Ceramic cords coiled on spools The ceramic cord is a basic low-cost material that can be rolled out on the square flanges directly from the spool.

Metal Reinforced Gaskets (MRG) added API 607 approved, high temperature resistance facing material TheMRGgasketwithanAPI607approvedmaterialasfacing material can be designed and manufactured to fit directly to the flanges. The steel will control the compression of the facing material and secure correct surface pressure without destroying the gasket. It is a good, easy handled gasket that fulfils the purpose in this application environment.

Exhaust manifolds are characterised by high temperature and a continuously turbulence. Betech offers a wide variation of possible flange gasket solutions which are especially developedforTurbineExhaustDuctingapplications.

Unique, Tailored Wire Mesh GasketThe unique Wire Mesh Gasket is made to secure that a correct flange clamping load is achieved by the load of the bolts applied to the washers that are in between the two special mesh cords. The combination of the special wire mesh and the steel washers prevents crushing the gasket. The space washer also secures a stiff bolt connection, meaning steel to steel contact through the bolt connection allowing a correct pre-tension of the bolt.

RTJ w. modified PTFERTJ

Ring Type Joint Gaskets for Subsea (RTJ-S)Atwaterdepthsbetween4,000and10,000ft.thehydro-static pressure is not only high but also contains internal system pressures. Such critical applications underwater demand special subsea gaskets instead of the regular Ring Type Joint Gaskets.

Subsea versions in all RTJ styles with pressure balance holes are available for underwater utilization to prevent pressure lock when connections are made up underwater.

TheRingTypeJointsforSubseahavetheSRXandSBXseries, the “S” prefix for Subsea. These gaskets have intersecting vent holes that allow a pressure less metal to metal initial contact between the flanges and groove underwater. This vent hole lets any water trapped between a ring groove bottom and the sealing area of the gasket to escape that can interfere with make-up underwater.
