FLANGE
Single Stud Replacement / Hot Bolting DTIs
DuraSquirt® SSR DTIs (Single Stud Replacement/hot bolting DTIs) are single-use mechanical load cells that visually indicate when a specific stud stress has been achieved. Designed to be used during hot bolting operations, in accordance with ASME code: Hot bolting or SSR is the sequential removal and replacement of bolts on flange joints while under reduced operating pressure.
SSR DTIs are to be used anywhere a specific diameter of bolt is to be tightened to 35-80 ksi bolt stress. SSR DTIs are marked with bolt diameter, SSR designation, and ksi.
