Yup, just a brief on this subject.
Heat exchangers are devices used to transfer heat energy from one fluid to another, gas to gas or gas to liquid.
Typical heat exchangers are seen around in most unexpected location. From household appliances as air conditioners, refrigerator etc. Boilers and condensers in thermal power plants are examples of large industrial heat exchangers. There are heat exchangers in our automobiles in the form of radiators and oil coolers. Heat exchangers are also abundant in chemical and process industries.
Heatexchanger sizes varies from couple of square mm (heat sink in computer cpu) to length exceeding hundreads of square meters!
From simple study flow to complex flows.
Heat exchanges as they say “comes in all sizes and nearly for all duties”
We will, in my next post discuss about fundamental of heat exchangers.
If you Google the word you will get morecthan a billion results. That just shows how it closely associated to industry, to us.
But at the same time ut shows how wast the subject is.
The purpose of next few blows is to simplify your search by telling you what to ask and where to see.
Figures crossed 🙂
Past few months I was thinking of creating a post on heatexchangers. I think now is the time when i can write a bit on this subject.
There are numerous sites available which will explain verwell about this subject. But as usual they lack the subject matter. What we all are interested in. The core, the ‘how’s part of it.
In my next few pposts you fand this information.
Take care.
B 31.3 is an ASME code for Process piping, Multiple time we come across situation, where we need to calculate the design pressure for a pipe.
In such cases, ASME VIII-Div-1 seems helpless, and B 31-3 comes for rescue.
Clause 304.1.2 talks about Straight pipe under internal pressure,
Where,
P > Internal design pressure
D > Outside diameter of pipe
S > Stress value of material as per table A-1
E > Quality factor from Table A-1A & -1B
Y > Coefficient from table 304.1.1
Compare equation 3a with ASME VIII-1 Formula (UG-27)
The formula is completely same, except factor PY against 0.6 P!
Y factor varies from material & Temperature, which varies from 0.4 to 0.7
As I’m working on one of the project, where I’m manually doing calculation, I thought this will be fastest way to share!

After getting my self stablaized in new company… now i’m evaluating the world around.
Filtration is the business, which is common to many needs, and hence it has been seen across the continent
Which brings me to todays discuss, short but sweet, and as usual with a promise to update you more as i learn more about this.
From Pressure vessel point of view, suddenly I’m exposed to number of Code of construction, which includes the old daddy ASME, PD-5500, AD-2000 and new comer like EN 134445. the new code i’m now exposed to is GB-150!
How many of you know this code? and importance?
GB-150 is Pressure vessel code for Pressure vessels in China! it very closely follows ASME, but has its own style! and its governed by Government.
In next few days, i;ll be sharing my finding as i’m all set to compare all these codes.
As an Indian, i like to as Indian Code for pressure vessel IS 2825. mostly its requirement by Gov. agency, but ASME is well accepted here in India, and IS 2825 closely follows PD 5500.
in my next post i’ll be sharing more about the comparison of three codes, ASME, EN & GB
keep reading & Posting!
