Re: [MW:15018] Re: Differance between PSL1 AND PSL2 PIPE/SHORT LENGTH JOINTES PIPE ISSUE/PSL2 CARBON STEEL PIPE

Mr. Sahid Alam,

If we understand the process, you are doing spiral welding of pipes(or) pipe welding in 5G position with pipe on rotation.

Short cut lengths  of pipes beyond 2 meters are allowed for welding. If they are  circumferential joints, make sure that, the pipe seams are oriented by 90 deg.  Hence pipe lengths of 7 mts and above should not create  any problem at all.

Hi there,

 

I am wondering what is the difference between API system PSL 1 and CSA system Category I? Also, the PSL 2 and Category II? The only thing I aware is the temp. for Impact test which is 0 deg. c for PSL 2 but -45 deg. c for Category II. is that all?

 

Cheers guys!

DEAR EXPERTS                  WHAT IS DIFFERANCE BETWEEN PSL1 & PSL 2 CARBON STEEL PIPE.   I AM DOING INSPECTION FOR PSL2 CARBON STEEL PIPES (BY SAW PROSESS AS PER API5L).   OUR PIPE'S LENGTH ACCEPTANCE CRITERIA IS 12 METER TO 18 METER.     MANUFACTURER HAS SO MANY SHORT LENGTH PIPES LIKE AS 8 METER, 7 METER & 10 METER.   HE WANTS TO JOINT TWO SHORT LENGTH PIPES BY SMAW PROCESS.   I WANT TO ASK THAT IF MANUFACTURER IS JOINING TWO SHORT LENGTH PIPES THAT PIPE WILL BE ACCEPTED AS PER API5L FOR PSL2.   MANUFACTURER IS SAYING THEY HAVE APPROVAL FROM CLIENTS ABOUT ABOVE MENTIONED ISSUE.ME SHOULD GIVE RELEASE FOR THAT PIPES OR NOT.   IT IS ALLOW OR NOT/AND WHERE IT IS MENTIONED THAT FOR PSL2 PIPES IF LENGTH ACCEPTANCE CRITERIA IS MENTIONED BY CLIENTS/API5L AFTERTHAT MANUFACTURER WILL JOIN TWO SHORT LENGTH PIPE AND HE WILL PROCESS THAT PIPES AS  PER PSL2  PIPES.     REGARDS MOHAMMAD SAJID ALAM INSPECTION ENGINEER KUWAIT
