Using 09MnD normalized steel pipes will do!
Thank you; I didn’t write it clearly back then – it’s ASME pipe material
SA-333-6 can be used; no problem
Except for SA-333 grades 1 and 6 (minimum impact temperature of -45°C), the other grades are available, but impact tests at the corresponding temperatures must be conducted.
It’s definitely no problem to use SA-333 6 at -48 degrees; see the discussions in the following post: https://mp.wei*n.qq.com/s/i-ZqfTKBGqt-NgzVD3rnig. However, SA-333 is not the specified material for heat exchange tubes – SA-334 6 should be used instead. As for the chemical composition of the materials and the temperatures they can withstand, SA-333 6 and SA-334 6 are identical. Conclusion, the use of SA-334 6
