Our client is asking us to put expansion joints on the suction of all pumps in the thermal power plant that we are designing and building. pneumatic, centrifigal, everything. What defines the need of expansion joints in these pumps? I imagine anywhere where there is heat or vibration, but at...

The owner is an american company. Regardless, we always try to fulfil american standards in order to guarantee the work quality, even thought they may not "officialy" apply

Thats exactly what i'm referring to. Is there a standard or code that demands this type of piping in underground piping systems?

No,i'm not talking about thickness. Double walled pipe can be any thickness. I'm talking about pipe with two walls, meaning an interior pipe inside of an exterior pipe. One inside the other. After re-reading this post, i noticed that it may seem slightly sarcastic or harsh. That isn't the...

Hi everybody, We are building a thermal powerplant in Peru, where many oily-water drainage system is underground. It has been suggested to us that all these tubes be double walled because they are always double walled in power plants in the US. I understand that this is good engineering...

Thnx JKseagull, that will come in useful. Any others have input?

Sorry, i'm not familiar with them, where would i start looking,who is the issuing body?

thanks, any others?

Hi all, I am writing a specification for a "Steam and Water Analyzing System (SWAS)" and want to know what are the codes and standards that govern the construction and testing of a steam and water analyzing system (SWAS)?

How do you define the MDMT (minimum design metal temperature)? What ambient temperture do you need to be able to define it?absolute minimum? average minimum? If i have an absolute minimum of 3.9ºF (-15.6ºC), what would the MDMT. please help me here, i'm dying with this mess!

Thank you all for your quality answers! stars for everyone!!!

Does a carbon steel dry air receiver for instrumentation air, require internal coating?

Thanks everyone. The location of the plant is in a remote area of argentina, near the end of the world. The basis of my question was if i should absolute tempertures and humidity to define the WTB or not. When i did the calculation, the absolute DBT, gave me a WBT that was far beyond what is...

Thanks MintJulep. What does one do when they don't have the standard or those specific tables. I know i don't. Is there a accepted practice for calculating (in the office... wrapping the sock around the bulb doesn't count) Maybe what i'm getting at is what values does one use in the...

I know this seems to be a very easy question, but if i knew the answer, i wouldn't be asking, please forgive me for being so naive. I understand that WBT is so critical in cooling processes, that we have begun to question how we define the DESIGN WBT. WBT is not difficult to design, but what...
