[MW:4306] PIPELINE AS PER BP192 and CP SYSTEM WELDING

Hi,
In a pipe line which is made as per specification BP 192, cathodic protection is provided on either side of the underground road crossing. the heat numbers of the pup pieces of the cathodic protection system are different from the mainline pipe heat nmbers, is it required to have a separate WPS qualified with this heat numbers too, since it is welded with the main line.
Please clarify.
 
Regards
J.N.M
