Product Description

 

RTJ gaskets are designed to seal by “initial line contact” or wedging action between the mating flange and the gasket. It is essential to choose a softer metal of the gaskets while the flange’s material should be harder to make sure the ring type joints can give a very tight and efficient seal after applying pressure on the sealing interface through bolt force. Usually, the ring gaskets are used in oil, petroleum and chemical process fields. As precision machined, metallic sealing rings, ring joints are suitable for high pressure and high-temperature applications.

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.

Materials

RTJ gaskets are available as standard in soft metal and in 304, 316 and stainless steels. Versions in other materials on request.

 

Style R ring type joints are manufactured on oval (2962/R) and octagonal profiles (2961/R).
Both styles are interchangeable in the modern flat bottomed groove.
Octagonal profile joints are interchangeable on flat bottomes groove flanges which have a 23 degree angle groove wall

Advantages

  • Metal-to-metal contact creates a reliable seal
  • Suitable for extreme pressure and temperature requirements
  • Certified quality (including surface hardness)

API 6A 150LB 304SS Oval Ring Joint Gasket 0

Programming interface ring Joint gaskets come in two fundamental sorts, an oval cross segment and an octagonal cross segment. These essential shapes are utilized in pressures up to 10,000 Rubber Seals and Gasket. The measurements are institutionalized and require uniquely notched spines. The octagonal cross segment has a higher fixing proficiency than the oval and would be the favored gasket. Be that as it may, just the oval cross segment can be utilized in the old sort round base notch. The more up to date level base furrow configuration will acknowledge either the oval or the octagonal cross segment. The fixing surfaces on the ring joint sections must be easily completed to 63 smaller scale inches and to be liberated from shocking edges, apparatus or babble marks. They seal by an underlying line contact or an edging activity as the compressive powers are applied.
