pressure rating 1

[Mefi01]

hello there,

I am working on a project where I am asking a vendor to provide me with a system of a pressure rating of ANSi #300. The vendor has recommended both ISO15783 and ISO2858 pumps. Please let me know if the suggested pumps are compliant with my system?

No.

As shown in your other (more basic) inquiry about the basic piping terms and definitions, ANSI 300 "pound" is NOT a "pressure" that can be used to select a pump, flange, or pipe wall thickness.

It is a "definition" of a class of different fittings (of different thicknesses and diameter!) that are welded to pipes to create pipe spools and assemblies that can withstand different internal pressures at different temperatures and when made of different material.

I agree.

ASME class 300 (It hasn't been ANSI for decades) is a pressure rating.

The pump spec is the international standard for pumps.

so completely different things.

This is like saying I have a requirement for 660V and here is the code for a transformer. Will it be good enough.

You seem though to be dabbling in things out of your knowledge and experience level.

This is potentially lethal.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

MJC - Do you see the presence of an MBA absolutely everywhere???

You're clearly heavily scarred by something, but I don't think MBAs are the root of all evil.

Mefi01,
You should share all the data you provided to the pump vendor who recommended the pumps for you. So, we knew better what's the design conditions for your project.
I thought the data should include more requirement than just ANSI #300 pressure rating. On the other hand, if this vendor proposed a pump with only the pressure rating info, you should look for other vendors who can ask for the adequate questions in order for recommending a right pump for the project.

Well LitteInch, perhaps I'm a bit scarred .... but there are many people who agree with me

We see this time after time after time .... young people who are suffering by being assigned jobs outside of their training. What do you think causes this problem ?

If not the uncaring project management, then who ???

What is your explanation ???
