* These flanges have limited bolt load, flange allignment is critical.

The above calculations are based on the use of a ASTM A193 Grade B7/B16 bolt with a coefficient of friction of 0.14. The flanged assembly must be fitted with a Klinger Soft Cut Gasket. Please forward any queries to: ryan.hough@klinger.co.za
