If you want to use a butt-welded fitting like a reducer in a line, the wall thickness of each side needs to be matched with the corresponded pipe on that side because they are going to weld to each other. so, you can use the pipe wall thickness for your fittings. It means in reality you need to...
A line number needs at least 3 parts: service, size, and piping class.
It seems that two firs parts are clear to you. So, the last one (M) should be piping class. Piping class identifies the piping component specifications in the line, not only base material, but also type of the components and...
Hi guys,
As we learned in academic textbooks, we can calculate linear thermal expansion of a metal part by the following formula:
ΔL = α.L. ΔT
where α is linear thermal expansion coefficient for a specific material.
When we go to the table C1 of Appendix C in B31.3, we have: linear thermal...
