Large Diameter Pipeline PCCP Valves and access entry points
Large Diameter Pipeline PCCP Valves and access entry points
(OP)
Since there are no general standards for large diameter pressure pipelines. I was wondering what would be a good rule of thumb to use for minimum valve distance for a transmission line of let's say 72 inch RWM PCCP? Also, what minimum distance would you use for access entry points; some call them manholes? I assumed a min. distance of 3,000 feet for butterfly valves seperation and still not sure about access entry points. Maybe OSHA has a regulation on it. Most stuff I've been finding has been on gravity lines.
If there is any other guidance you can provide in designing large diameter pipelines? It would be greatly apprecaited.
In fact, it would be nice if they devoted a section of the forum just to large diameter pipelines.
Thank you all,

I agree with you fully but before meeting with the client and the design team, I was looking for a second opinions and better judgment. I'm just a junior engineer. Thank you though for your appreciated follow up.
There are no branch connections just a transmission line from point A to B. It's 27,600 LF of pipeline. Also, it's for raw water transmission.
