PQT for A333 Gr.6 pipe

[ramen samanta]

Dear Experts,

In our project, we have to establish a  WPS /PQR for A333 Gr 6 Pipe (P-1,Group-1) and Flanges A350 LF-2 (P-1,Group-2).   Process - GTAW+SMAW (with ER 70S-2 and E7018-1).

How to conduct/establish one combined PQT with P-1,Group-1 to P-1,Group-2 ?? 

Can we make two PQT separately of below options :-

One Pipe to Pipe in 6G position and other any Plate to Plate in 4G/3G position of which Tensile Strength 70 ksi) - Is it acceptable  as per ASME Sec-IX?

Please clarify.

 

Thanks in advance,

R.K.Samanta

There is no reason for 2 pqrs. If the design and construction code does not have any impact test requirements you can do your pqr using only pno1/gropu no 1 material. Pqrs are usually done with plates since in Asme code diameter is neither essential nor supplementary essential variable

Hi,

What you have mentioned is one of the option. or you can directly weld pipe to flange and carryout the procedure qualification for which you may have to procure additional flanges.

If you want to use pipes, you can run the PQR using A333 Gr 6 and API 5L X65 pipes , both are P1G2 materials. Hope there is impact test requirements.

[MUNHOZ Sergio TECHINT]

Dear Sirs

 

·        A333 Gr 6 is P1 G1 and not P1 G2

 

·        Question: Under B31.3; Impact test required; can I combine one single Pipe to Pipe P1 G1 PQR with  one single Pipe to Pipe P1 G2 PQR and issue one Pipe P1 G1 X Pipe P1 G2 WPS ?

 

Best regards

Sorry for the error..what I intended to suggest  was the dissimilar combination of PIG1 and P1G2 can be achieved if both pipes are used..

Mr Dilintas;

 

Thanks for your fast reply; I was just checking if someone had got a permission to wave this instruction.
