1" sch 40 pvc tube bending

[chicopee]

I need to make a slight offset,less than 10 degrees on the reference pipe. Is it possible to evenly heat the pipe with an open flamme torch? Any suggestion will be appreciated.

I don't think you really want to do that.

Your question is phrased as if you have two different problems:

An "offset" is usually a condition where two pipes are parallel, but have moved sideways from each other: The "offset" is the distance between the two centerlines. For 2" PVC pipe, use two 45 deg elbows with a short mating piece in between.

However, you described the "offset" as if it were a "10 degree bend" - which for a 2" common PVC pipe can be done with your hands and hot water. No heat is required for that small a curve. Glued (welded PVC fittings) joints won't be effective for such a shallow bend in such a small pipe.

racookpe1978, actually you are correct. I should not have called it an offset, I should have stated it as a 10 degree elbow.
The line pressure will be in the range of 10 psig and I will try to bend it with hot water eventhough the melt temperature is around 350 deg. F.

Take a piece of cardboard and wrap a "U" around the pipe area that you want to bend.

Then take a heat gun and evenly heat about 4X the length that you need to bend. The Pipe should bend quite easily.

I would strongly encourage you to try this on a scrap piece of pipe first.

Good luck!

The trick in heat-forming plastic is to work r e a l s l o w, recognizing its poor thermal conductivity.

If you get impatient, you'll just blister the surface or crack the workpiece. Don't expect to use the first one you try.
