Dear All,

I just want to know if it is needed to perform the alignment checking if the pipe connected to the pump suction has a "rubber bellow"? Based on my initial result, the displacement of the flange connected to the pump nozzle at load case WNC+H is reaching 168 mm. It exceeded the allowable displacement set by API RP 686 of 1.5 mm.

Thank you and hope for your reply.

Regards,
