High Pressure RX37 Weld RTJ Ring Joint Gasket API 17D Chemical Resistance

High Pressure RX37 API 17D RTJ Ring Joint Gasket

The Ring Type Joint Gasket is initially developed for high pressure/ temperature applications found in the petroleum industry and is primarily used in the oilfield on drilling and completion equipment.
However, today this product range can also be found on valves and pipe work assemblies, along with some high integrity pressure vessel joints.

Primary features:

1. Resistance to high temperature and pressure, suitable for high pressure flange

2. Excellent temperature resistance. Permanent temperature range -200℃to +550℃

3. Very high operating pressure limits (320 bar)

4. Good chemical resistance

5. High-grade, reinforced and blow out safe gasket as per UW (Healty and safety at Work Act), high operating safe

6. Very low leakage rate, meets TA-LUFT requirement

7. No ageing, no embitterment, even at high temperature

8. Asbestos-free, physiologically harmless, disposal with domestic waste

9. Good handling during transport, installation and removal. Mechanically stable, scratch-resistant

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.
