Hi
I have searched the forum but couldn't find a question quite like mine. If this has been discussed before my apologies
The closed loop consists of a tubular heat exchanger (for heating the hot water) and a plate heat exchanger (for exchanging heat to another fluid). The heat exchangers are...
Hi
The customer's maintenance engineer is requesting manual ball valves for manual steam isolation (double block and bleed). I have used gate and globe type (Spirax Bellows Seal) in the past with good result. I prefer ball valves as automatic steam isolations. Something like a Keystone KTM...
Hello
What are your thoughts on globe control valve body material choice for high pressure steam? The supply pressure is 41.5 barg 254C design and typically 37 barg saturated operating, which is dropped down to 10 barg for distribution to heat exchangers, process vessels etc. The control valve...
Hi :)
I had a go at the thermal calc due to expansion by Prex (faq378-1339) however I would also like to look at calculating the pressure rise due to nitric acid decomposing into gases (NO2, O2) in a shut in pipe eg. between 2 valves. I do not believe I have the thermodynamics set up correctly...
