Notes:

1. Based on Ansi RF Flanges at Garlock preferred torque. When approaching maximum pressure or continuous operating temperature, or 50%of maximum PXT, consult Garlock Engineering 1-800-448-6688.

                                                          

2. ASTM F37B Sealability, milliliters/hour (1/32" thick)                                                            

ASTM Fuel A (isooctane)

Gasket load = 500 psi 3.5 N/mm2)

Internal pressure = 9.8 psig (0.7 bar)

Nitrogen: 

Gasket load = 3000 psi (20.7 N/mm2) 

Internal pressure = 30 psig (2 bar)

                                                                                                 

3. DIN 3535 Part 4 Gas Permeability, cc/min. (1/16" thick)

    Gasket load = 4640 psi (32 N/mm2)

    Internal pressure = 580 psig (40 bar)

 

4. Saturated steam service guidelines:

bullet

For optimal performance, use thinner gaskets when possible

bullet

Minimum assembly stress = 4,800 psi

bullet

Preferred assembly stress = 6,000 psi - 10,000 psi

bullet

Retorque the bolts/studs prior to pressurizing the assembly. Never retorque a pressurized assembly.

bullet

If the service is superheated steam, contact Application Engineering at 800-448-6688

          

     * above 150 psig, contact Application Engineering

 

This is a general guide and should not be the sole means of selecting or rejecting this material.                                                                                                                                  

 

ASTM test results in accordance with ASTM F-104; properties based on 1/32" (0.8 mm sheet thickness)
