For safety you may have a limit of up to 1.4% max for seamless pipe unless otherwise agreed or it could go up to 1.8% for other types. You need to say the type and WT.   PJA   SAVE TREES  - THINK BEFORE YOU PRINT From: materials-welding@googlegroups.com [mailto: materials-welding@googlegroups.com ] On Behalf Of rajeev arora Sent: Friday, May 22, 2009 11:33 AM To: materials-welding@googlegroups.com Subject: [MW:2225] min and max accepted resiual magnetisum   Dear All,   Please give some reference of the max. or range of acceptance of megnetisum in line pipe of API 5L Gr 70.   Reagrds   Rajeev Arora -- Regards Rajeev Arora "DON'T LET SOMEONE BECOME A PRIORITY IN YOUR LIFE...
