DuraSquirt® Target Stress DTI
DuraSquirt® Target Stress Direct Tension Indicating Washers are designed to be used as verification devices when torquing bolted flange joint assemblies. They are single use mechanical load cells that visually indicate when a specific bolt stress has been achieved. Using your existing fasteners, torquing pattern and tools, the DuraSquirt® Target Stress DTIs will let you know if your toque generated the desired stud stress, and a visual marker that the flange has been completed as required.
DuraSquirt® Target Stress DTIs are available in bolt diameters from 3/4” up to 1-1/2” designed to clients’ required stud stress from 35 KSI up to 80 KSI in 5 KSI increments. They are not specific to a particular flange class or type, gasket or seal.
