Install the bolts and washers, and attach the nuts. Tighten the bolts in a star-
patterned sequence to equalise compression. (See bolting torques 2.5.3)
2.5.3 Bolting torques
The information in this section is to the best of our knowledge correct. Since
conditions of use are beyond our control users must satisfy themselves that bolt
torques are suitable for the flange/process/conditions of their applications.
2.5.3.1 High tensile steel bolts only
The following recommended torques assume the use of high tensile bolts. If
ordinary carbon steel bolts are fitted see section 2.5.3.2. for bolt tightening
torques for this type of bolt.
Min. torques are in Nm (lbf. ft.). Max. torque = Min +10%.
