Marking and Identification (standard):
The outer surface of each Ring Type Joint should show the manufacturer’s name or a trademark, the gasket number like R67, RX37 or BX155, gasket’s material in abbreviation(check below our chart), as well as the standards like ASME B16.20, API 6A, API 17D, etc.
Materials
RTJ gaskets are available as standard in soft metal and in 304, 316 and stainless steels. Versions in other materials on request.
All RTJ gaskets are manufactured to API standards, guaranteeing consistent quality.
Industries
Oil & gas industry
Petrochemical industry
Flange connections
Pipe connections
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.
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.
