Hello all,
I have done stress calculations for multiple years and have a good understanding of hoop vs longitudinal stresses for buried pipelines. Recently I have gotten involved with pipeline strain but I am struggling to understand two key things:
First, several codes talk about a 0.5% or...
I am working on a project that involves laying fiber lines for several miles. We will be crossing multiple creeks and drainage ditches. Several of the creeks are extremely eroded with silty bottoms, and we will need to fill them in to allow for crossing. Similarly, several drainage ditches are...
Hello all,
I have heard quite a bit about stream bank stabilization techniques but nothing about stream channel stabilization. Is formal stream channel stabilization even feasible with the current USACE general permits (I don't think so) as I think any armoring technique threatens to change the...
Hello all,
I am looking for opinions on the viability of laying pipeline in various corridor widths. For example, say that the client only wants to purchase a 20' easement without additional work space, that the line is 10", 3' average depth, mostly cross country, and we have roughly 5000 LF to...
In looking through a few welded steel pipe fitting catalogs: I see that for ASME B16.9/ASTM A234 WPB 3R fittings, the manufacturers list the wall thickness as the same as the fitting WT (for example for 6” schedule 40 - WT is shown as 0.280” WT). Is there no thinning in the pipe wall due to the...
