[MW:24373] Time between Hydrogen Bake Out and PWHT

Dear Sirs,

We welded a 15E Pipe material (16 inch - 87mm thickness).
Our procedure will be preheated with 205 deg centigrade then welding and will be
( hydrogen ) bakeout and perform PAUT, If accepted in PAUT, immediately followed
by PWHT and will perform MT.
Process is B31.1

The joint has been accepted by PAUT, my query is, how long should be acceptable if there is a delay in performing PWHT?
Right now it is almost 1 week that the welded joint is not yet PWHT.

Need your advice.
