RE: Loop

I'm still relatively new, but I had to deal with some pretty extreme expansion loops on a previous job.

Q1: I don't think you accurately CAN design a loop without having a temperature, at least not without just taking an extreme temp and going off that.

Q2: Well, looking at this matrix and using 160 degrees as an example, it's saying that the expansion of steel pipe is 1.224 inches. I believe it doesn't matter where you put them and how far apart, just as long as you take into consideration the 1.224 per 100 feet. It purely depends on your environment in which you are piping and client requirements I'm guessing.

Q1. What thumb rule says after how many distance/length we should provide a loop.(unknowingly temp.)

Q2. If we know the temp. of line then after what distance loop should be provided. I mean to say a loop should be design to bear max. how much expansion
