Dear sirs
Thank you for your reply.
i know that rated point is guarantee point in purchasing any equipment.but this point usually (in API-610,674,675 ,...)related to capacity,differential head.
but in API-676 we can see rated point in liquid specification table.(unlike other standards). this...
Dear All
i have question on revised API-676 std datasheet.
As you know ,new std api-676 changed liquid properties section.
There are "Min",Normal" & "rated" condition.(see attached picture)
Min and normal condition is obvious.my question is about "rated" condition.
which condition shall be...
base plate will be grouted
pump will be manufactured acc to API-610 at vendor shop
- Where is the Pump being installed?
At petrochemical site
- Where is the pump being manufactured?
in shop
- Does the Pump manufacturer offer a choice of Base Plates?
- What Base Plate is furnished as a standard...
Dear all
please guide me on selection "drain-rim" or "drain-pan" or "partial drain pan" BASEPLATE (requirement of API-610)
which key parameters should be considered in selection?
Thanks
Dear 1gibson
would you mind explain more clearly?
why this note was added in API?
could the acceptance of the performance test change without considering this note?
thank you
Dear all
according to the Table 14 of API-610, the tolerance of the Power is +4.
there is a note b that state :
Under any combination of the above (cumulative tolerances are not acceptable)
would you mind help me to know about this note?
thanks
thank you for your response
as you mentioned in second point,in worst case, every centrifugal pump could see the shutoff pressure(even if there is minimum flow line in the discharge). so may i conclude that all pumps should be designed for dual pressure?
can anyone help me with following clause of API-610:
"Unless otherwise specified, vertically suspended, double-casing, integral gear-driven (type OH6) and
horizontal multistage pumps (pumps with three or more stages) may be designed for dual pressure ratings. If
specified, suction regions shall...
your note was usefull for me Artisi.thank you.
and i have another question.
can we guess the quantity of the vent on the casing?I've seen Between bearing with three vent on casing.is it usual?
Dear all
how we can judge the claim of manufacture about self-venting is true or not in the between bearing pump?
top-top nozzle arrangement can be self-vent ,but when? i saw the pump with TOP-TOP nozzle that is self-vent and other one that isn't.
what about side-side or inline pumps?
i think...
thank you all for your replies.
guidance of zdas04 is great for realizing.but unfortunately the pump is in site.the pictures were taken already.
i asked one friend who has been in purchasing the pumps,he told me they were pipe and 1/2" ,sch 80
but can pipe bent like this?
as entrance to the...
Dear all
we have auxiliary piping for the pump seal plan
i don't have any related document,
how i can recognize that is pipe or tube?
the picture for two pump were attached.
