Gaskets are the critical sealing element in every flanged joint. The correct gasket selection for pressure class, temperature, fluid service and flange facing is essential to prevent leakage and ensure joint integrity.
Tecflow Energy stocks spiral-wound gaskets, ring joint (RTJ) gaskets, flat sheet gaskets and speciality sealing products for oil & gas, petrochemical and industrial piping systems.

Questions fréquentes
What gasket should I use for a raised-face (RF) flange?
Spiral-wound gaskets (SWG) with inner ring and outer centering ring are the standard choice for raised-face flanged joints in oil & gas service. For lower-pressure utility applications, flat sheet gaskets (graphite or PTFE) are commonly used.
When do I need a ring type joint (RTJ) gasket?
RTJ gaskets are used when the flange has a ring type joint facing (grooved face). They are specified for high-pressure service (#600 and above), high-temperature service, sour service and subsea applications where a more reliable metal-to-metal seal is required.
