Re: [MW:28650] API 1104 Internal Clamp and External Clamp

this is 18" dia pipe. If internal clamp is not possible, (like tie in joints) we can use external clamp . We developed different PQR-WPS for both internal and External  clamp welding. Internal with downhill progression and external clamp wps with uphill progression .  But in a circumstance we used in Internal clamp and Welded with the parameters as of External Clamp.  Only the clamp type in different 

Is it acceptable ? 


With Regards

Dear  All,


External clamp and internal clamp WPS and PQR procedures are qualified with downhill process and uphill process respectively.  But one joint has welded with internal clamp following  all other variables as of external clamp WPS


Is this acceptable ? If yes , how can we justify ?

Pls help very urgent
