Ring joint gaskets
Ring type joint gaskets (same as ring joint gaskets, RTJ) are
primarily used in the Oil, Gas and Petrochemical industries to seal
flanged connections subject to high pressure and temperatures, and
form a metal to metal seal with the flanges.
The ring joint gaskets fully comply with the ASME B16.20 standard
and the API spec 6A requirements (where applicable).
Materials of ring joint gaskets includes Soft Iron, Low Carbon
Steel, F5 Alloy Steel, 410 Alloy Steel, SS304, SS304L, SS316,
SS316L, SS347, SS321, Nickel Alloy 625 & 825, Duplex, Super
Duplex, Monel & other materials available.
TCI RTJ gaskets are manufactured in accordance with API-6A and ASME
B16.20 specifications and come in four basic profiles:
R type (oval and octagonal) solid sections to fit standard ring
joint flanges with trapezoidal grooves.
Types RX and BX with complex bevelled edge sections for wellhead
pressures exceeding 700bar
These basic shapes are used in a variety of applications with
pressures up to 20, 000 PSI. The dimensions are standardized and
require specially grooved flanges by where a corresponding "R" or
"BX" number is assigned for pipe size and pressure class for gasket
The Ring joint gaskets are mainly used in High temperature,high
pressure pipeline(steam and petrol industry,petrolchemical
industry)tower,trough,heat converter,pipe joints.
