Please briefly describe the mounting of the pump to the ground. In the photo, do I see a rail? How is expansion compensated for in the existing design?

Thanks

Subject: [PipingDesign] Anchor near pump nozzles

Dear Group,

I would like your advice on the subject item.

An existing electric driven centrifugal pump installed at a crude pipeline booster station has a pipe anchor on both the suction and discharge lines. This intent is to eliminate any moments and force transfer to the pump nozzle. Pls see the attached photograph. The pump operates at ambient condition (Design ambient temperature is 82 deg C). Please see the photograph after upload.

Will this arrangement pose a problem during the piping alignment with the pump nozzle. I feel, any fabrication tolerance of this anchor that will not allow the pipe flange to match exactly with the aligned pump nozzles will reflect as a load on the pump.
