    UG-85(b)

    Hi! In my opinion, the 900degF (480degC) pertains to the minimum temperature where heat treatment takes place (e.g. applicable to Aging treatment/Precipitation Hardening) on a material. The Code 'maybe' simply specify it to consider not only the common heat treatment range-from 1100degF...

    Heat number transfer on to the materials received

    I think you could defend this (some with tag&heat numbers and others without tag&eat no.) by: The product was received in the condition as per ASTM A6 Section 18.1.4.2 and 18.6.1.

    ASTM A106 section 4.4

    Hello! Yes, as per the standard, cold-drawn method for smaller pipe (D<2") can be conducted. I think the main reason of this is that these line sizes, D<2", are mainly used in utility lines (non-critical/process service) therefore reduced yield strength and hardness by plastic deformation...
