what is the yield strength of the 60 inch steel pipe wrench in either ft lbs or inch pounds
I have found in your Q&A that 36 is 45000 inch pounds and 48 is 52000 inch pounds so by the increase in this does that mean a 60 inch pipe wrench is good for 59000 inch pounds? or 4917 ft lbs?
Thanks

Heavy Duty Pipe Wrench Torque
I was curious if Rigid was planning on doing any testing on the heavy duty wrench heads, in regards to work hardening or stress splitting of the upper jaw. More specifically the area where the upper jaw turns into a threaded neck, the 90 degree area shearing off of the teeth. We have recently seen this phenomenon happening in our shop...

Thank you for contacting RIDGID. We perform regular evaluations of all tool components to make sure they meet our quality standards.
When an upper wrench jaw breaks at the radius, it is likely due to the force being exerted against this point. There should only be 2 contact points with the pipe, the upper jaw and the lower jaw. If a 3rd contact point is made against the hook jaw radius, failure can occur.
If you would like further assistance, please feel free to call our Technical Service department at 888-743-4333.
