I have to agree with all posts above. I have purchased PE tanks from multiple vendors and all of them have required a flex connector/hose at the sidewall flanges. They really are not designed to handle any sort of load at their connection points. However, I do believe it is the sidewalls that...
This specific run is PVC but this is great information for me to reference! Thank you for taking the time to provide your input! Due to the design of the rack, our pipes will be resting on UHMW roughly every 4' or so, so we should be good on local loads.
I do believe this gives me enough...
Again, great input. Thank you much!
Out of curiosity, what pipe stress program are you using/ would recommend? I am not sure I have one at my disposal but can recommend my company look into one. I believe I have an argument to get one without much fuss.
I am proposing we bolt strips of "slippery...
I believe Combo valves are sized based on the flow in the system, not so much the sizing of the pipes. You need to be able to outpace the air that you are pushing through (air release) and allow in more than you are removing (vacuum break. In my experience the combo valves are capable of much...
Someone who didnt know what they are doing, and I'd like to not make the same mistake, lol!
My gut tells me to do this:
Anchor at the ends and one in the middle. This would allow freedom to move in the direction if the green arrows. Please note, no Z movement . Placing the anchor in the middle...
Thank you all for the comments, this is great!
Perhaps the image above is not the best to properly portray the use of the u bolts, here is an overall of a single route. Y axis is roughly 160' and X is roughly 53' with the green being the pipe.
Our thermal expansion should be minimal as we...
Hello again LittleInch!
"Thrust Block" is not the correct term here. We are calling a weldment that we mount to the exterior of the pipe flange to react the thrust force as a "thrust block". I am not sure who came up with the name for the weldment, honestly. Here is a photo of one for...

Good morning all,
I have been tasked with figuring out where to install thrust bracing on 90deg elbows for an open pipe system. These are going to be a mix of SCH10 SS and SCH80 PVC pipes, varying anywhere from 1" to 12" in diameter. My thought process here, and please correct...
Thanks, 1503-44, it has been a lot of non standard practices for me (a relatively new employee to this company) to get used to.
And thank you to all who responded. I believe I have enough information and data to back it up to move forward with significantly less ARVs in our system.
This seems similar to a topic I posted a week or so ago, as previously mentioned. The Walski number (P) is a useful tool however I have noticed it is flawed for the case of a vertical change in pipe elevations. Rise/run*100 always =0 in these instances. Unfortunately for me, I rarely use...
We are no stranger to struvite formation/cleaning/prevention. Replacing our pipe instead of cleaning (which by the way, is not much pipe) was an uptime based decision. Cutting out the PVC and installing new has been historically quicker for us to get our system back operational. Admittedly, that...
@1503-44
Struvite build up requires us to replace the piping every so often. We are hoping to get a year out of it, but 6 months is when we start to notice the pumps ramping up to maintain flow rates.
@LittleInch & @1503-44
I very much appreciate the files and graphs! I will be taking a look...
@ LittleInch
When is the 1m/s rule of thumb NOT applicable? I'd also be curious to know where that number came from. Either way, thanks for the input!
As far as gravity fed lines, they almost always stay below the outlet of our tanks for this very reason. We also hardly ever have gravity feed...
Hello all!
I am working on refining and improving a piping system for a facility that is in design. One item I would like to reduce the overall use of (if possible) is air relief valves we have. Currently, we have been cautious and included an air relief valve at every local high spot and one...
