Would have added more info on the piping alignment or allowable deviation in between piping flange and pump nozzle, allowable shaft deflection during buttoning up the flanges.... Grouting details would have given more details like grouting method, clearing of blow holes or defecting grouting, final grouting....

Old practice advised to use Ecc bottom flat but latest engineering practice says to use Ecc top flat no metter whether tank is A/G or U/G in order to avoid flowing bubbles in pump.
Pipe size selection is based on pump nozzle size, pump nozzle size is based on process flow and head requirements. Types of pump selections are different and need to consider process and site conditions
I am piping designer and I have worked in JGC Japan. Please improve yourself as described below. 1.Discharge piping on the nozzle is not good practice. Load on pump nozzle cause disturbance of pump alignment. 2. Reducer with pump nozzle is not good. There should be 5d straight run between Reducer and pump in order to provide turbulence free flow to pump. 3. There is to be Ecc Reducer top flat even if flow is from A/G tank.
@@samueljebaraj4742 Ecc B/F is an old practice. If you see American "piping guide" old version, there's same. However, the latest practice in most reputable companies like Technip, Bechtel, Florabia, JGC, Aramco & Adco is to keep Top flat as latest practice. The reason is to avoid bubbles generation in the upper cavity of reducer. The RPM of pump is 3000 or sometimes more, even the little quantity of bubbles attack the pump impeller like bullet which reduces the life of pump. Moreover bubble causes noise and vibration too. Piping Designing is a vast field, however Designing around pump is most easy and simple. If you are keen fully interested, we can share our views on every type of piping Designing in future.
I liked your upscale page posts
The video is very helpful. Thank you about information you provide.
Thanks.share to all
Shouldn't we use 3D or 5D of spool for ecc red from suction?

We should open the discharge isolation valve to lower the load on the prime mover? right?

What about cavitation formation when we use flat side bottom eccentric reducer in positive suction head.
Ihave the same Question relate to Esentric reducer

Good animation

Very informative. Thanks
very good information thanks
at 2:55 how long the minimum pipe after reducer?
O
Hi Technical Piping, i have a question: Why we should fit eccentric reducer, maybe can make avoid air pocket formation? Thanks a lot!
Old practice advised to use Ecc bottom flat but latest engineering practice says to use Ecc top flat no metter whether tank is A/G or U/G in order to avoid flowing bubbles in pump.
Why isn't an isolation valve recommended?
Informative
How do I located the suction line and discharge
arent we supposed to use a minimum of 5D rather than 3D?? API 686 Specified a minimum of 5D, please clarify. thanks
In which plateform this video made?
please explain and make video vibration standard of pump
Good
without grouting between foundation and base you can expect excessive vibration and noise
Gr8
Brother please mention standards accordingly...for reference..
Hi, new subscriber here. A question. The 6% slope is absorbed for the inlet gasket?
You would have to make a angular / mitered fit up at the eccentric reducer to get your slope.
please tell me how to select size of pipe
Nag Lp it's depends on the pump nozzle size...
Pipe size selection is based on pump nozzle size, pump nozzle size is based on process flow and head requirements. Types of pump selections are different and need to consider process and site conditions
sir ,please make ur vedio in Hindi also
the background music is interpreting the voice
yes
please share your video to us
inclining upwards 6mm for 100 mm is wrong in.
it is 6 mm for 1000 milimeter

Hi
How can I contact with you !!!
Plz reply
I want to ask couple of questions.
@@AliAhmad-df2sf Can you ask the question at this panel. Please introduce your self too. I Don't mind to render my services.
Why don't go for bottom flat bro for eccentric reducer ?? is there any standard reason in it ??

Kindly try to avoid this background music. So annoying and not able to listen to your explanation.
