Dear All
Very Appreciate for all responded.
I am already uploaded the sample of the drawing.
My opinion is the pipe in HDD section look like is in the bentonite fluid and it has the buoyancy force acting to the pipe.
The tie-in point with bend (almost cold bend) is on the ground as i mention...
Dear Alchemon
very appreciate for your answer.
Our pipeline design base on ASME B31.4,
I would like to know the stress check at tie-in point with HDD both end during operation.
Just like a hanging point after back fill and operation at the overbend point, I am not sure combined stress should be...
How to calculate pipeline overbend stress on the onshore pipeline during operation?
I have the problem just like after completed HDD work and tie-in with overbend to keep the pipeline profile according to requirement.
Can anyone to help to solve this stress calculation check?
Dear Sir

And this is another location for the problem about the HDD stress calculation during pullback.
We can not construction by another method due to the area limit.
How to calculate stress of HDD construction according to S-curve in the horizontal plan and also curve in the vertical in 1 HDD.
It look like combination radius of horizontal and vertical.
Very appreciate for all answer
