Re: [MW:7063] Tube sheet to tube joint

Hi, You can use the existing WPS for the proposed one,since the P.Number and Group number are same.For seal weld (Tube expansion+seal weld) no need mock-up test). Tube expansion percentage: Light Expansion - 3% to 5% Heavy Expansion - 8% maximum.   Thanks & Regards,   (karthik) Karthikeyan.S QA/QC Manager Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.
