NOTES:
1 Based on ANSI RF flanges at our preferred torque. When approaching maximum pressure, continuous operating temperature, minimum temperature or 50% of maximum PxT, consult Garlock Engineering.
2 ASTM F37B Sealability ASTM Fuel A (isooctane): Gasket load = 500 psi (3.5 N/mm2), Int. pressure = 9.8 psig (0.7 bar) Nitrogen: Gasket load = 3,000 psi (20.7 N/mm2), Int. pressure = 30 psig (2 bar)
3 DIN 3535 Part 4 Gas Permeability, cc/min. (1/16" thick) Nitrogen: Gasket load = 4,640 psi (32 N/mm2), Int. pressure = 580 psig (40 bar)
4 Saturated steam service guidelines: > For optimal performance, use thinner gaskets when possible. > Minimum recommended assembly stress = 4,800 psi. > Preferred assembly stress = 6,000 psi to 10,000 psi.
> Retorque the bolts/studs prior to pressurizing the assembly. > If the service is superheated steam, contact Customer Service.
