Spetoring ® Metallic rings RTJ

SPETORING® gaskets are applied at extreme temperatures and pressure loads in refineries, power plants, petrochemical industry, oil drilling, pipelines, valves and pressure vessels.

►RTJ-R   SPETORING® RTJ-R (octagonal) gaskets have been widely used mainly in oil and gas industry. RTJ-R gaskets have total blowout resistance, its design provides two sealing barriers, therefore they do not fail in very dangerous installatios. In special styles available also as a plug, wiht centring ring, galvanized; manufactured almost exclusivily in dimension standards according to NPS 36.
►RTJ-OR   Oval gasket manufactured from steel or special alloys, available in the same dimensions as octagonal gasket. May be applied also in very old, semi-round grooves in flanges, blowout resistant, has two sealing barriers; applied in installations containing dangerous medium; in special styles available as the plug with centring ring or galvanized; manufactured almost always in dimension standards according to NPS 36.

SPETORING® RTJ-RX gasket is a modified version of RTJ-R which has higher active internal pressure resulting in increased contact stress. RTJ-RX gaskets are manufactured from various sealing materials, in special constructions with galvanic coating.

►RTJ-BX   SPETORING® RTJ-BX gaskets are engineered for the highest pressure ratings up to 20000 psi. It is a solution requiring special facing arrangement. Blowout resistant, opening in the axial direction has the function of balancing the pressure loads in the situation when the inner sealing barrier is not tight. The gasket manufactured only in dimension standards to NPS 30.
►R-S   Lens gaskets manufactured from steel, thanks to spherical contact area with the conical flange arrangement the local stress is accumulated and very good tightness is achieved. Totally resistant to blowout, unlike RTJ gaskets they have only one sealing barrier; applied in flanges from PN 400 and to DN 400; in special constructions also with centring ring and galvanized.
