Pipe is having nominal OD and thickness depends on varying schedule whereas tube OD & thickness is fixed.If the dimension matches it may not be a problem in using.

But Pressure tubes are distinguished from pressure pipes, i.e, T11 & P11 with very fact that the tubes are suitable for the application of external heat while conveying pressurized fluids while prssure pips are not. Please revert on this issue.

As a general practice pipe are used to convey the fluid and tubes are specified for heat transfer application with using calculated thickness based on heat transfer coefficients.However sometimes in process furnace tube are interchanged with pipes if dimension matches. regards,

>Can SA199T11 be replaced with A335 P11 ? SA199 T11 need hardness test, A335 P11 don't need. I think T11 can replace P11, but P11 can't replace T11.
