I have a question regarding the weight of pipes
Thread Content
Why is the pipe weight (for gas pipes) in Table 26-22 on page 4-27 of the Chemical Process Handbook, Volume 2 (3rd edition), much higher than the theoretical pipe weight shown in Table 27-21 on page 4-89? Logically, gas isn’t that heavy! For example, the theoretical weight per meter of a 820×10 tube is 200.26 kg/m, while for the 820×9 tubes used in gas pipes as shown in Table 26-22, the weight per meter is 337.17 kg/m. What’s going on here? Thank you
Reply to 2# shengguanwang: They should all be carbon steel pipes; even if the materials differ, the difference won’t be that significant
Looking at the raw materials, the difference between materials of the same kind is not significant
