Tightening Force

Recommended Tightening Force Tables
Lined Pipe and Fittings Bolting Materials should be of good quality, clean and well lubricated and to the site standard. The use of washers is recommended to ensure correct even torque. Bolts should be brought finger tight and then tightened through the use of a torque wrench in strict sequence of diagonally opposite pairs. This, and all subsequent torquing, of bolts should be undertaken at ambient temperature.
*Torque bolts diagonally opposite each other in pairs Please note that PTFE is suject to cold flow or “creep”. It is therefore strongly recommended that all bolts are retorqued a minimum of 24 hours after commissioning or following the initial full process cycle. The torque of all bolted joints should then be rechecked at least annually thereafter.
