centrifugal pump code and standard 3

[Roger00]

Hi All,


any other code and standards for centrifugal pumps in specific in power plant industries besides API 610 (petroleum, petrochemical, natural gas)?

thanks

 

[DubMac]

Try the Hydraulic Institute standards; they are much less rigorous than API.

NRC has certification requirements if you are talking nuke plants. VERY RIGOROUS!

There are also ANSI/ASME B73 series standards, but they're likely smaller than you're looking at if you're talking power plant pumps. Provided we aren't talking nuclear power, so far as I know there's nothing that says the pumps have to be built to any standard period unless it's an owner requirement. There are manufacturers out there than make 'API 610-ish' pumps that are fit for service but are built to manufacturer's standard construction, and frequently were compliant once upon a time to an older version of API 610 and the manufacturer just didn't see a need to update.

Process Industry Practices (

http://www.pip.org)

also has a set of guidelines for different types of equipment, including pumps, for improved installation and reliability purposes.

There may be additional ISO or DIN standards that cover comparable construction outside the north american market (aside from ISO 13709, which is technically equivalent to API 610 newer editions), my experience is inside the north american market.

also try ISO 5199

Why do you need a code/standard - you need to expand your enquiry a bit more for understanding?

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

Thanks All ,

@Artisi , the reason is that before project , contract shall be produced which may contain code and standard. Codes affect project cost.

 

[Artisi]

And codes too ridig for the application increase prices.

[Roger00]

P@ artisi and everyeone , could you please share links free download hydraulic institute code for centrifugal pumps , and blowers and compressor. I only have API 610 , and i always use that.

Thanks

 

[Artisi]

Have you heard of Google?
Try centrifugal pump standards.

I have tried google before ur comment. I think you are a cocky and not a "right to the point" person. If you dont have it just say you dont have it or just dont reply.

You should think first before you write such things about a longtime and reputable member. Klick on Artisi's profile and you know what I mean. The members here are not paid for their help. You are the one who asked for help and your initial question was rather vague. Nobody here likes to spend time with things you could easily do by yourself. That's not the purpose of such a forum.

 

[Roger00]

@mical , i think all my questions i threw were in a polite sentence , and i said thanks to everyone for all the answers. Im a new member and considered my self as junior. I am sorry if my question is considered too easy or vague to you or artisi but i never force anyone to answer me. I think it s better to respect people in answering even if they are junior or simply dont answer if you are not interested to. Btw , i respect all member in this forum senior or junior. Thx

Roger00,
Recognizing all of the members on this post, I truly don't think anyone is trying to personally persecute you. Everyone acknowledges, respects, and appreciates your politeness I'm sure; but making sure people feel good about themselves is not the intent of this forum. I have a theory on why some of us get a little irritated by certain questions, and our replies might seem a bit caustic. Please don't take this the wrong way, as it is not intended to harm but might help explain why you got jumped on with your post.

As an older goat, I've have been noticing changes on the approach learning recently; I call it the "cut & paste" approach. It seems that more and more, the task of "learning" has become: go collect what everyone else has said on a subject and stuff it in a file box somewhere. Then you may consider yourself qualified on that subject, since you can later do a keyword search on your filebox and regurgitate the work of others.

That is not learning, that is a combination of laziness and short-sightedness; well intended as it may be.

We have spoken on this forum before about the tendency for many "specifying engineers" to spit out a list of every relevant specification on a particular subject, add zero input of their own except the statement "All the following specifications must be adhered to"...., and think they have done their job. They are nothing more than copy room clerks, and do a great disservice to their employer and the engineering profession.

Again, don't mean to single you out or offend you in any way, I hope you will continue participating in this forum. You will find that Artisi is not picking on you, he is our resident ankle biter and I have found him to spread his criticisms/witicisms quite fairly across the board; and there are a lot of ankles that need biting.....

Never thought of myself as an ankle biter, more like a grumpy old man when necessary but aren't we all at some time.
As for assistance, I'm more than happy to help anyone when ever I can, but it's nice to see some input / research / investigation having been undertaken together with a well constructed question from the OP rather than, "what's NPSH", "what pump code", "what's a propeller pump" "how long is a piece of string", "I want to know / tell me how to xxxxx" etc., usually without even a please or thank you.
It also seems that these OP's are the ones that you have to drag information from - a bit like trying to get blood from a stone, they usually disappear in a cloud of smoke before the thread reaches a conclusion to pop up again at a later date with further nonsensical questions.

Asking for links to "free downloads" of copyrighted standards also puts people off. Plus, you need to know enough about what you're doing to know which standards would be suitable for the application. If you don't have a current copy of the relevant standards, they are available to purchase for a (usually) reasonable cost from many legitimate sources. Buy them, read them, and decide which one suits your application best, then reference that standard(s) in your RFQ.

 

[1gibson]

Or if it isn't too much work (please continue reading) you could review the standards, mark the features you really want, and write your own 10-15 page spec that includes similar or equivalent provisions. Keep it as short as possible.* Understand the reasons behind every clause you put into your own spec, you will learn a few things. If you think you like something in a spec but don't know why it is there, that is the type of thing you ask in this forum.

*=If a sales person can thumb through a clear and very concise customer spec, they will quote the features you want but will not charge you API prices.

 

[SNORGY]

Actually, after years of participation in these fora, if I had a pu,p-specific question, Artisi's the person I'd be asking (no disrespect intended to the other pump specialists here...).

 

[DubMac]

You said it, Brother!

 

[Rinchterninsob]

On the original question, and for everyone else, with regards to a project, you must realize that a pump is not finished after it has been engineered and manufactured. It must still be installed and operated. At times, this is more critical to reliability and efficiency than the former.

Therefore, never forget API RP 686.

This is an invaluable reference to ensure that installation is performed correctly. Otherwise, your equipment simply will not last. If your installer is not familiar with it, find another.

Also, for a power plant application, make sure that thermal growth is calculated properly for a cold alignment. Make sure to use the specific material's temperature coefficient and not just general thumb rules.

 

[clay87]

At a large power plant, our feed pumps and booster pumps, and condensate pumps are api610 or meet the spirit of api610 . Also other pumps that see elevated temps or considered "critical" are api610. Pumps that just move low-temp water around tend to be ANSI b73,1. If you have a specific application or scope, I might be able to provide more info and recommendation.

IMO, There is no standard to take the place of the detailed analyses needed when specifying large circulating water pumps.
