Higher voltage cables are sometimes oil filled after installation which may require continuous support.

The length of a 90 degree bend is 90 divided by 360 times Pi times D (= 1/4xPixD) where D is the mean diameter of the bend in the rod.
Similarly you can use any number of degrees as a ratio of the total circumference (360 degrees)

It all depends on what you are trying to do regarding loading, corrosion resistance etc. but the easiest way is to use an internal sleeve pipe with outside diameter slightly smaller that the ID of each pipe.

The HDPE lining is hard up against the steel pipe so you are very likely to damage or go straight through the lining if you do a hot tap.
If the pipe is a pressure pipe the lining is returned at the flange joints or at least there is a special flange. I would check those first.

Rather long winded but if you add each point as a separate series you could call the series the loadcase. Of course you could not join the dots thereafter.
Otherwise in Excel 2007 you can only have x, y and / or series that I can see.

You would have to use both an arbitrary point and alignment. A total station is not linked to GPS for example so you would be able to measure distances and angles and obtain quantities. If you wanted to repeat the measurements you would need to secure the arbitarry point and the alignment...
From the photographs it looks like Weholite pipe. In which case the spiral winding is to resist backfill and imposed loading whilst using the material efficienly and not for water pressure.

According to my understanding, the question siva3180 is asking is "why is the pressure higher at the higher elevation?"
I cannot explain it and he also thinks that it is the wrong way around (as do all the other responses).

If the pipe is straight then there is nowhere for it to go. The danger would be if a section is removed and a blank fitted without restraining. The 6' head could then push the pipe out of a coupling.

This company makes conduits suitable for blowing the Fibre Optic cables (FOC) through with air. We have been told that distances of 5000m are possible. The FOC is just the strand and does not need the armouring etc...
With pure dry sand small grain (i.e. wind blown) I am wondering if vibration had a hand in the UHB with the particles moving down past the pipe as it rises.

To truncate the number to say 2 decimal places use =TRUNC(Cell, 2).
Add a column, use TRUNC to create the truncated number and then Copy and Paste Special to get the truncated number into the original column. Delete the added column.

You could set up the page as you want to see it and then name a range at the bottom of that page and hyperlink to that.

Maybe I have misread your question but it seems as if you are talking about a section of landline not an offshore pipe whereas the previous respondents seem to reply based on an offshore pipeline.
Onshore pipelines in a single trench will depend on the Owners requirements for maintenance and...
As the "beam" is a tube the propensity for buckling is the same in all directions.
I would think that the tube is more likely to buckle in the vertical direction for a static case as that is the way that the tube is deflected due to self weight.
For a dynamic lift and swing operation there...
The pipe into the lake system is close to industrial systems for desalination plants.
One problem is growth inside the pipe. With fresh nutrients flowing past all the time there is a build up. In desalination plants there is a hypochlorite injection point offshore to kill the growth.
You would...
