1. A friction coefficient of μ=0.16 has been used for calculation of bolt torques.

2. Tightening torques listed above are suitable for ASME B16.5 standard instrument flanges when assembled using the bolting supplied with the chamber. The figures
given in the table should be considered as guidelines. Suitable verifications of all components are recommended before put in service.

3. The torque values are applicable to both soft iron and stainless steel rings.

4. Not supplied as standard. If needed, see supplied documentation or consult factory.

5. Fiber gaskets are not normally recommended for flange ratings Class 600 and higher, unless permitted by instrument supplier. Refer to the manual supplied with the
measuring instrument.
