The 16 ton is made to bend sch40 pipe up tp 3" ID.
Pipe capacity: 1/2'', 3/4'', 1'', 1-1/2'', 2'', 2-1/2'', and 3'' pipes
HF sells one. I have one from Homier. Got it for $75 it was missing the 2.5" die. I've bent a lot of 2" pipe (2-3/8"OD) with it. I cut some pads for the outer rollers out of a short section of pipe and that really helps prevent denting by the rollers.

I've bent some 2" SS Sch10 with success. Also some 2" boiler tubes that are not as thick as sch 40. It ripples a little on the inside of the bend but usually does not kink. The times I had a kinking problem were with the boiler tubes where there was serious corrosion/non-uniform walls. I am not familiar wiith oilfield pipe but the ODs mentioned seem to correspond with NPT 2" and 2.5" sizes. I guess someone just has to try it and see. Here is a gate I made from the 2" boiler tubes. It is 7' tall x 16' wide.
