We have a low temperature piping application (-60 °C) we are installing. Our pipe specification calls for either L7 or B8 bolting.
Most of this has been installed with B7 bolting instead. The person that approved the use of B7 based his approval on the fact that the material specifications...
We have a new process that generates a waste water stream. The waste water will be acidic, but we can adjust the pH to suite.
Process piping AFTER the pH adjustment is planned to be carbon steel (grade A106).
We would like to limit the final pH adjusted volume to minimal.
So what is an...
I am developing a pipe specification for Dow Syltherm XLT operating at -100 °F to + 200 °F and up to 150 psig in pipe sizes 1/2" through 6".
I am planning to use T304 SS pipe and fittings due to the low temperatures. I'd like to use class 150 flanges and ASTM A320 Grade L7 bolting if...

I'm examining the potential for using ASTM
A333 Grade 6 for a -50 °F system.
Its obvious to me that this will be a more expensive system than our typical A106 piping (for warmer temps), but I don't have a good feel for how much.
Does anyone have a feel for relative installed costs of A106 vs...
I have an application for a single pass (both shell side and tube side) heat exchanger. This ia a low temperature (-70 °C shell, -25 °C tube) application primarily concerned with heat removal resulting from a chemical reactor in a batch process.
I would like to orient the exchanger vertically...
