TSG Type V

Features & Benefits

• Extremely high reliability sealing and insulating for all critical services
• Seals and insulates at all pressures up through ANSI 2500# and API 10,000¹#
• Withstands severe service conditions, including large bending moments, vibration, temperature, and pressure cycling¹
• Tackles corrosive environments, including high concentrations of CO2, H2S, produced water, etc.
• Outstanding isolating properties for cathodic protection, galvanic corrosion, and other pipe system isolation needs³
• Pressure activated for reliable sealing and eliminating costly leaks
• Precisely sized to the bore to protect flange faces and prevents turbulent flow at flanged connections to mitigate media-induced corrosion and flow-induced erosion.
• Seaco can match the ID of any flange assembly which can greatly mitigate the effects of flow induced corrosion, erosion, and MIC common of other types of gaskets used in piped flange connections
• Mitigates galvanic corrosion in dissimilar metal flanges
• Insulating Kits (sleeves and washers) always include high strength double washers and full-length sleeves for maximum assurance against short circuits
• High strength laminate material resists failure due to excess compression (i.e., over tightening bolts)
• Spring energized PTFE seal provides radial load and encapsulation in the seal groove to eliminate cold flow
• Available to match any flange specification (ANSI, API, BS, DIN, AS, others)
• Can seal mismatched RTJ Flange with Raised Face Flanges

Applications

• Flange insulation in conjunction with cathodic protection

• Insulation between dissimilar metals to prevent galvanic corrosion

• Wellhead isolation from inter-connected flow lines

• Valve connections

• Christmas Tree connections

• Compressor connections

• Tanks and heat exchangers with sacrificial anodes to increase anode life

• Mating mismatched ring-joint to raised-face flanges (VCS will seal in ring-joint, raised-face and flat face/slip-on flanges)

• Eliminate fluid trap corrosion between ring-joint (RTJ) flanges where high concentrations of CO2, H2S, other aggressive hydrocarbon media are present

• Eliminate turbulence and flow-induced erosion between ring-joint (RTJ) flanges.
