Hi All,
Looking for code calculations to determine the thickness of the flat plate to blank leaking tubes in the shell and tube heat exchanger and the weld thickness.
Shell:
Material - 304L
Medium - Air
Pressure - 6 bar
Temp - 120 C
Tube
Material - 304L
Medium - Saturated steam
Temp - 215 C...
Hi All,
I am looking to see if there is a potential risk of galvanic corrosion when welding a 316L nozzle to a 2205 duplex pipe with E2209 electrode. I understand that there is a risk of SCC and may even accelerate the SCC at the welds but ignoring that for now, will there be any galvanic...
@StressGuy: XL83NL is correct, the pipe is spec'd to run at that pressure and temperature. In reality this will run at a very low pressure but will still have 95 C water(not considering heat losses).
I have routed the pipe by 180 deg from the pump suction(with a straight run) and placing the...
@Snickster- Great resources and examples, thank you for sharing. Additionally I was able to understand the reasoning for allowable 0.016 in displacement from API 610, Annex F. Correct me if I am wrong, I believe as long the displacement (expansion due to pipe + pump casing/nozzle) is <0.016 inch...
Thank you. You are right, the nozzle has been modeled as rigid and thus any small expansion creates massive loads. I assume the pump manufacturers can provide the detail for allowable displacement? I can place anchors close to the nozzles and model the nozzles as free ends which will give me max...
The pressure is 4 bar.
The problem is when only one of the pump is working, the temperature difference in pump 1 line (15 C) and pump 2 line (95 C) causes opposing loads on the pump nozzle.
thank you for your advice.
Hello All,
I am new to pipe engineering, and I am trying to do pipe stress analysis to learn the software(Autopipe). I would like to get your opinion on routing the followng pipe based on your experience to reduce the nozzle load on the centrifugal pumps. I would also appreciate if you could...
