120'. Or maybe 120°. Or something.

This handbook is in its eighth edition now, but, here's a full pdf of the fifth edition.

www.petrodanesh.com/.../Piping/Ebook/Pipeline%20Rules%20of%20Thumb.pdf

What do you mean by 40D?

Are you looking for the minimum bend radius, or, maximum bend at a joint?

The maximum allowable angle for laying the pipe will depend on what it's carrying.

The maximum temperature will depend on the material it's made from.

Degree of tilt from horizontal, temperature before wall softening or are you trying to grant an academic title while smoking your pipe?

I also don't understand what a digital camera or bra size has to do with a pie.

<...allaowble..> in terms of which applicable standard(s)?

Please supply the forum with contextual information that enables a signpost towards the answer to be supplied. It is not possible to do this with the relevant information having been withheld from the forum for unknown reasons.

Typical information needed:

  • Materials of construction of the pipe
  • Schedule of the pipe applicable to the pipe walls
  • Method of jointing of the pipe - welding? Flanges? If flanged, then to what standard?
  • Method of support of the pipe
  • Description of the contents of the pipe, including
    • temperature and
    • pressure
  • Method of insulating the pipe
  • Pipe painting specification
  • Etc.

It depends on so, so many things but the biggest would have to be what is the pipe material, what is the pipe transporting, and the pressure, how full is the pipe, what's the orientation of the angle in the pipe, what's the application, what local codes and standards are applicable. The list goes on.

Best pass this to an Engineer, engineering consultancy, etc if this is anything more than a simple application where a rough guide maximum angle is acceptable.

What exactly is the application?

A greater circle with its axis centered on the center axis of the pipe reveals the cross section of the pipe at the intersection of the pipe with this plane intersects the pipe.

Are you attempting to bend the pipe?

That's one long marijuana pipe, or is that the diameter? The 40 dummies should be placed 9 degrees apart while in the circle. Formula: 360/40 = 9.

You mean this?

You don't want to heat that above its autoignition temperature. Don't heat the can in fire, or you will singe off your eyebrows when it "goes off"!

Check the WD-40 SDS for further details.

That's why I prefer to heat hydrocarbons in a pure nitrogen or carbon dioxide atmosphere.

OK, let's have a "crack" at that.

It least it won't squeak on its hinges.

Hinged pipe? Now, there's a thing that might solve the Original Poster's problems.

Having never seen one, I suggest we start with a break-over loading shotgun as the exemplar upon which to base the following report: "Bang"
