Dear cheristine74 , Thanks for your help

TEMA CLASS R , I have a big no. Off commercial brass plates CU 200 with very good price. I want to purchase them. As usual our company uses Copper for baffles. What i want to know if commercial brass as a material with all his properities is accepted to use in baffles. If yes , what is the temp...

Explicit !!!! Please , if you have a certain questioner , you can ask me directly

Can i use commercial brass CU200 in manufacturing baffles of heat exchanger. What is the temp. Limit and restrictions???

It is required to replace the old firetube A-106gr. B WITH PIPE API 5L (IN STOCK ) as a material for firetube for heater treater (vessels that contain liquids produced from wellheads. Heat is introduced to the liquids through the use of a natural gas or hydrocarbon liquid burner that is mounted...

Natural gas air cooler

Partial pressure 1.14 psi

NACE 0175, as i want to use sa-179 hic material in gas cooler with 1000ppm at 275°f.

What is the partial pressure limit of wet H2S for carbon steel at what temperature

I know that duplex s.steel will be better but Galvanic corrosion can occur where different metals are coupled in a conductive fluid. So i prefer using SA-179 but i have some doubts about its behaviour with wet H2S.

Sorry , i don't know that my thread will appear in all forumes so i share it indvidually.

Recently, the gas process component has large change in some harmful component specially h2s which reaches to 1000 ppm. Now we want to replace the existing bundle for gas air cooler by new one. The existing material for the old bundle is Tubes sa- 214 Tube sheets, plug plates and end platez sa-...

@ MJCronin Thank you...

Dear SnTMan. The existing baffles were A-357 The existing tie rods stainless steel without material specs. Fluid in shell was hydrogen gas Fluid in tubes was effluent from reactor.

i don't want to select too cheap material, i have some doubt that sa-240 tp 304 is suitable for this temp. and hydrogen service as for effluent reactor cooler.

Dear MJCronin, Idon't know what do you mean with third world posting!!!!! i have posted a thread with a certain enquiry .if you need more details, you can ask about it without any sarcasm. This was an old effluent reactor cooler and the design was from an european manufacturer. We want to take...

But the temperature limit for sa-240 don't govern the design temp for cooler

I want to select material for baffles cheaper than sa-387 for effluent reactor cooler. Material of shell sa-204 gr.B Material if tubes sa-213 TP 304 TEMP. For tube side 430°c Temp for shell side 410°c
