Buralloy Ring Type Joint 2961

Buralloy ring-type joint 2961 (RTJ) gaskets are manufactured from metallic materials in compliance with American standard ASME B 16.20 and the API specification. Detailed monitoring of every manufacturing step guarantees that the sealing rings offer the necessary surface hardness. This creates a functional seal without damage to the flanges. This gasket type is used successfully in downstream refinery applications, for example. RTJ gaskets are also commonly used in high-pressure valves and the associated pipe connections and in pressure vessel joints.

Functional description:

Under axial compressive load, ring type joints plastically deform and flow into the irregularities of the flange groove. Since the contact area of the ring type joint is relatively small, a very high compressive load results between the sealing surface of the ring type joint and the flange groove. This surface pressure is further increased especially by the RX and BX RTJ variants. Both variants are able to seal extremely high internal pressures. RTJ gaskets are produced from metal, so they remain in their compressed form, even when the surface pressure is relaxed. The sealing function of the RTJ gasket is reinforced by the axial forces acting on the sealing surfaces.

Forms of supply:
  • Standard dimensions as per DIN EN 12560-5 or ASME B16.20
  • RTJ gaskets are available from stock in ½” to 36” and 15 mm to 900 mm sizes, and in the commonly available materials to suit most ASME and DIN flange dimensions. Larger sizes and special requirements are available to order.
