Subject: [MW:1925] equipment alignment tolerance

 

Hi All,   I  have worked 5 project here in middle east as Qc Inspector- mechanical equipment. In all project contractor's QCP is refered for alignment tolerance for verticality and leveling of equipment like column, drums and exchangers. I could not find any reference to this tolerance to international standards or recommended practice. My query is not directly related to welding, but can anybody give name of any standards or RP regarding erection and alignment tolerance for these equipment. (Not fabrication)   Thanks and Regards Ahmed Husain Borouge2 Abu-Dhabi
