FEATURES AND BENEFITS
• Seals and insulates at all pressures classed including API 15000 psi service
• Withstands severe service conditions including large bending moments, vibration, temperature and pressure cycling
• Designed to withstand corrosive environments, including high concentrations of CO2 , H2S, produced water, etc
• Outstanding insulation properties for cathodic protection
• Pressure-activated seals provide high confidence sealing and eliminate costly leaks
• Gasket is sized to the bore to protect flange faces from media-induced corrosion and flow-induced erosion
• Prevents turbulent flow at flanged connections
• Mitigates galvanic corrosion in dissimilar metal flanges
• Available to match any flange specification (ANSI,API,MSSP,BS,DIN,AS,others)
• Can mate mismatched RTJ with raised-face flange
• Easy installation, make up and removal
STAINLESS STEEL CORE
The standard stainless steel core is 316L. Special materials such as duplex stainless steel, inconel stainless steel can be made according the requirements.
