Tightening of TCBs

  Tightening of TCBs Before graduation of preloading, the related components shall be fitted collectively and the bolting assemblies shall be brought to a snug tight circumstance. This tightening technique shall be executed from bolt to bolt of the group starting from the maximum inflexible part of the relationship and transferring regularly closer to the least rigid element (touch to non-touch surfaces). In order to make certain that the preload in absolutely established bolting assemblies meets the specified minimal preload requirement, the installation process includes two tightening levels. The first degree applies a bedding torque to the bolts to make sure a firm contact among components. Pre-tensioning (stage 1) may be performed by way of: i.
