Re: [MW:10318] pqr api 1104

The range over which the diameter and wall thickness is qualified has always been a confusing issue in API 1104.  In paragraph 5.3.2.3, the key words there are "example of suggested groupings..."  Because they are suggested groupings, they are not mandatory.  Table 2 does not apply to establish the diameter and wall thickness range since the table is specific for identifying the type and number of test specimens for procedure qualification tests based on the diameter and wall thickness used for the procedure qualification.

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
