Ans 2>No NB Stands for Nominal Bore it is not the same as OD(Outside diameter).NB is a Nomenclature and is basically the name assigned to that particular Pipes.Please refer to the IS-10577/82 given in our Products to get the correct Outside diameter and Thickness of each pipe Category.As per the IS the pipes are classified by their OD (Outside Diameter) and not ID (Inside diameter).This is because the pipes need to be threaded at both ends or at one end as such the OD cannot Vary beyond a certain range as specified in the IS.
