Dear Littleinch, Yes you are right.we are trying to contact the vendor sending him the as-built isometric drawings for pulsation study.

Dear saplanti, Yes the pulsation damper valve is directly mounted on the pump nozzle. Even though when the pressure reaches 100bar more vibration starts. We adjusted the support span too,but no use.

Dear saplanti, Thanks for your prompt response. The pump is plunger type and used for flushing water with high pressure.

Dear Experts, Please find the attached CII file and Site vedio. The pump discharge line is vibrating heavily before 100bar. the process parameters are as follows; Design press= 197bar, operating press= 172bar, ope temp = 150deg C. kindly suggest to avoid the vibration. The model frequency...

Thank you little inch..in your answer I can see your professionalism. But how the guy i don't want to mention his name again. He should learn. Everyone are experienced in their field. When a question comes as challenging which is beyond the standard obviously we take suggestions from...

Dear All, project requirement is A333 gr 6, but readily available based on the chemical analysis report is A333 Gr 10. Can we use this? Experts share your opinions

ear Experts, For cold insulation we have contraction joints where we use butyl rubber sheet used as external bellow. But cost effective we are using EPDM rubber sheet which from same family and can be folded same as butyl rubber. Can we use EPDM, experts share you opinions

Dear all, We have LTCS Pipe(18" 160 sch A333 GR. 6), completed the flattening test. In the chemical analysis report shows manganese composition value is 1.49 but the range is between. 290 to 1.06 Shal we accept dis. Experts share your opinions

Dear mk3223 At site we are checking for alignment. It is about 6mm. There is no possibility to modify supports. If we place support close to pump nozzle loads are failing. Whole foundation completed around and not possible to change. Since it is only alignment, can we provide temporary...

Dear mk3223, Thanks for your reply. I request whether we can provide temporary supports near to pump nozzle during alignment check. Providing permanent support near to nozzle is not possible. Kindly suggest

Dear All, At the site, we are checking alignment but the values are about 6mm (Y and Z direction). The adjustable support is about 2.5m far from the nozzle which cannot be adjusted because the pump foundation everything completed. Hence we are requesting to provide temporary supports until...
