Abstract
A method for forming a pipe elbow comprises cutting a first precursor from a pipe. The pipe has an inner diameter surface and an outer diameter surface and a central longitudinal axis. The first precursor has a first end and a second end off parallel to the first end. Machining forms an interior surface having an arcuate centerline. Machining forms welding interfaces at the first end and the second end.
Claims21
A pipe elbow comprising:
- a first end and a second end off parallel to the first end;
