The pNBR bell details table presentation has been slightly modified to indicate those instances about which we know where the bell in question has been welded.
A cracked bell is indicated by the entire line being shaded light red; a welded bell is now presented with (just) the diameter cell being shaded light green.
There is no capability for supplying this information via the edit details facility, so please inform us of other bells which have been welded using a normal e-mail, or at the time of supplying other details by including a comment to that effect.
