FLANGE WN, 1500 LB,900LB,300LB, RTJ, ASME B16.5 ASTM A182 F44


RTJ Flanges are used for high pressure applications up to pressures as high as 15,000 psi (103 MPa).
The benefits of using an RTJ flange and ring is that the gasket is confined to a groove and has two sealing surfaces. 
The groove assures that the ring centers itself when the bolts are tightened.
