Re: [MW:10315] pqr api 1104

Thank u
 
 
Dear Muthu Bharathi
 
Table 2 is only for the specimens requirement for pqr as per dia .its does't say that range of qualification. Iam right?
According to 5.3.2.3 wps need to show only the dia inch as per grouping of 6.2.2
according to 5.4 essential variables does't say that dia is essencial variable only there is mensioned that the wall thickness in 5.4.2.5
as of my interpritation if the thicness with in the group wecan use the procedure for production weld irrespective of size
 
pls let me know if iam wrong

Dear Sir,

You may please refer Table 2 of API 1104 and from this table you may find diameter range and wall thickness range. you mentioned only dia and not wall thk. if the wall thk is as 20" dia  or with in 0.5" you may use the same PQR.



Thanking You,

Honesty is the best Policy
