Nice sharing friend

[@FransEsterhuizen]

Can you send me the selection steps I need to take to select the sea planl for my oil refinery

[@itsjustJay863]

Great presentation. On the plan 62, is the flush port always plugged? It appears that way on the graphic.
Thanks!

[@SiewertEquipment]

Hello Jay and thank you for watching. The Plan 62 is a Steam Quench on the atmospheric side of the seal. It’s used to remove solids build up like coking, or salting. The inlet should be on the top and the drain at the bottom, and YES the drain should always be left open. You can, and most people do, install a steam trap but make sure the maintenance is done on the tramp. If it plugs, the 62 will not work properly and you will fail the seal.

[@itsjustJay863]

Thanks but I was referring to the flush port. Looks plugged on the picture (in red)

[@SiewertEquipment]

Oh I see what you’re asking, the short answer is No that port is not always plugged. That port is on the process side of the seal and can be lined up with any single seal flush plan that the seal requires, like 11 or 13. Typically you will see this called out on a spec sheet or described as: “Seal Flush Plan 11/62”.

Could pressure gauges be installed in the mechanical sea itself in order to monitor the seal chamber pressure?

[@hamzadriss1358]

yes, you can use existing F connection of the pump or the F or PI connection from seal gland if it has been already advised to vendor.

[@raedsaad8737]

Thank you so much very good presentation, in our plant we use plan 53-B so what is the difference between 53A and 53B ?

[@satheeshkumar-mg6ru]

53A we will have seal pot only along external pressure, but in 53B you have heat exchanger along with seal pot,the pressure of buffer fluid maintained by Accumulator..

[@tawadhu1104]

@@satheeshkumar-mg6ru is the 53B more fragile to dirty fluid such as solid or sand compared to 53A? The pump installed in our facility has 53B seal type and the 1/2 inch flushing line between stuffing box and discharge head is frequently got burst eroded by the sand. I wonder if it can be solved by modify the sealing into 53A and permanently plug the flushing line.

[@ghosalarghya]

53B will have bladder accumulator which 53A doesn't have. Accordingly in 53A nitrogen mixes with the fluid. But in 53B it is not the case.

[@Varunkm110]

The main difference between plan 53A and plan 53B both are pressured barier plan 53B can handle more pressure than Plan 53A . In plan 53 A manually feed nitrogen .where as in plan
53B acuumaltor and bladder make up line separately . Almost plan 53B works has stand alone unit . If plan 53B fails check
the pressure of your process line . Consultant application engineer or system design engineer before changing any thing.

[@hamidkh.4229]

What about the API Plan 65 is it possible to use with the LPG pumps as a single arrangement ?

[@hamzadriss1358]

LPGs have higher vapor pressure meaning that your leakage will be gas and not liquid and gas tend to rise, therfore, the use of a plan 65 or B IS NOT recommended and useful.

[@mahmoudabdelsalam1432]

great presentation ... but kindly can you install the C.C option for writing text plese ??? .. its more hlepful for nonspeakers english

[@SiewertEquipment]

Hello, we are sorry. We are trying to troubleshoot why the CC are not showing, but we can't get it to work on this video.

[@ericcordoves2366]

In Plan 13, how can you make the seal chamber pressure higher the suction pressure for vertical pump?

[@nnn7369]

Just my opinion, the pump discharge pressure is the same as the back casing where seal installed, because impeller accelerates fluid, you may look up how centrifugal pump works video made by engineering mindset!

[@807004407]

WHAT about Plan 31?

[@naveenpandey3255]

sir can you explain how can we find whether primay seal is leaking or secondary seal is leaking in double seal pump? please reply

[@oscargonzalez7857]

It is normal for the seals to leak, this is what they are design for. As long as there is no leak to the atmosphere, then it is normal.

What is polymerizing fluids?

[@pranshukumar7925]

Which crystalise on lower temperature.

[@srisainagaraja3808]

What is full form of API
