Flange Insulation Gaskets Kits
Our Flexiteck insulation kit passed ASTM D3850-12 Fire Safe, analysis was performed by SGS TGA
Style : 280
Are designed to maintain the integrity & reliability of the pipeline & piping system through safety & corrosion protection. Also provide and effective seal & electrical isolation of flanges. By eliminating metal to metal contact, static current is halted to prevent corrosion & aid in the cathodic protection of the pipe.
Construction of high quality materials that have a high dielectric constant and low water absorption, our kits are available for all size flanges, ranging from ½” to 144” in all ANSI & API standard.

L-seal gaskets are state-of-the-art in near zero leakage static sealing. The elastomer sealing element is encapsulated in the electrically insulated retainer. And permits only micro-exposure of the seal to hostile environs of fire, chemicals and corrosive fluids.
ADVANTAGES OF THE L-seal
Can be utilized with mismatched flanges
Can be utilized with misaligned flanges
Can be used in place of RTJ or BX rings
Little initial torque required
No re-torquing required
Sealing ring cannot be left out
Seal design tested from 0 – 100,000 psi
Reusable
Compensates for pressure fluctuations, compression changes, vibrations, temperature, etc.
Greatly reduces human error during installation
Large selection of materials available
Three to four times the dielectric strength necessary

Type “E” is a full-face gasket with same outside diameter as the flange and precision cut bolt holes.
This design facilities proper alignment of the gasket during installation. This assembly minimizes the ingress of conductive foreign matter between the portions of the flanges outside the raise face and reduce the risk of bridging.
Type “F” gasket are made to fit the raise face portion of the flange only. As there are no bolt holes in the “F” gasket, the outside diameter of the gasket fit tightly into place assuring a well centered position.
The gasket material incorporates high-strength, glass-reinforced epoxy laminated bonded to a stainless steel core. This provides the strength of a traditional metallic gasket while maintaining complete electrical insulation between the flange faces. Seal grooves are machined through the laminate insulating material and into the stainless steel core which provides a strong base for the seal to seat into and breaks the potential leak path that is inherent in glass laminate materials. Spring-energized Teflon internal face seals are installed in the dovetail shape seal grooves to provide the reliable sealing.
Extreme high-reliability sealing and insulating solution for all critical services. Seals and insulates at all pressures classed including API 15000 psi service.
· Seals and insulates at all pressures classed including API 5000 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 catholic 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 flanges>
· Easy installation, make up and removal
The standard stainless steel core is 316. Special materials such as duplex stainless steel, Inconel stainless steel are can be made4 according the requirements.
The standard glass-reinforced epoxy material is NAME G10; G11 is available when the temperature requirement is higher.
