Abstract

A roller tool for forming circumferential grooves around a pipe is disclosed. The tool is rotatable about an axis of rotation and has a circumferential surface engageable with a pipe. The tool surface includes first and second surface portions positioned in spaced relation and oriented perpendicularly to the axis of rotation. A radial surface portion extends between the first and second a surface portions and is oriented substantially parallel to the axis of rotation. An angled surface portion is positioned adjacent to the second surface portion. The angled surface portion is oriented at an angle up to about 70° and slopes away from the second surface portion.

Claims

1. A roller tool for forming circumferential grooves around a pipe, said roller tool being rotatable about an axis of rotation and having a circumferential surface engageable with said pipe, said surface comprising:

a first surface portion oriented substantially perpendicularly to said axis of rotation;

a second surface portion positioned in spaced apart relation to said first surface portion and oriented angularly with respect to said axis of rotation;

a radially facing surface portion extending between the first and second surface portions and oriented substantially parallel to said axis of rotation.

2. A roller tool according to claim 1, wherein said angled surface portion is oriented at an angle up to about 70°

relatively to said axis of rotation.

3. A roller tool according to claim 1, wherein said angled surface portion is oriented at an angle of about 50°

relatively to said axis of rotation.

4. a roller tool according to claim 1, wherein said radially facing surface portion is curved.

5. A roller tool according to claim 1, wherein said radially facing surface portion is angularly oriented with respect to said axis of rotation.

6. A roller tool for forming circumferential grooves around a pipe, said roller tool being rotatable about an axis of rotation and having a circumferential surface engageable with said pipe, said surface comprising:

a first surface portion oriented substantially perpendicularly to said axis of rotation;

a second surface portion positioned in spaced apart relation to said first surface portion;

a radially facing surface portion extending between the first and second surface portions and oriented substantially parallel to said axis of rotation; and

said second surface portion having a cross sectional profile selected from the group consisting of a convex shape and a concave shape.

7. A roller tool for forming circumferential grooves around a pipe, said roller tool being rotatable about an axis of rotation and having a circumferential surface engageable with said pipe, said surface comprising:

a first surface portion oriented substantially perpendicularly to said axis of rotation;

a second surface portion positioned in spaced apart relation to said first surface portion;

a radially facing surface portion extending between said first and second surface portions and oriented substantially parallel to said axis of rotation; and

said second surface portion having a first face having a first angular orientation with respect to said axis of rotation and a second face having a second angular orientation with respect to said axis of rotation.

8. A roller tool according to claim 7, wherein a slope of said first face is greater than a slope of said second face.

9. A roller tool according to claim 7, wherein a slope of said first face is less than a slope of said second face.

10. A roller tool for forming circumferential grooves around a pipe, said roller tool being rotatable about an axis of rotation and having a circumferential surface engageable with said pipe, said surface comprising:

a first surface portion oriented substantially perpendicularly to said axis of rotation;

a second surface portion positioned in spaced apart relation to said first surface portion and oriented substantially perpendicularly to said axis of rotation;

a radially facing surface portion extending between the first and second surface portions and oriented substantially parallel to said axis of rotation; and

an angled surface portion positioned adjacent to said second surface portion, said angled surface portion being oriented angularly relatively to said axis of rotation and sloping away from said second surface portion.

11. A roller tool for forming circumferential grooves around a pipe, said roller tool being rotatable about an axis of rotation and having a circumferential surface engageable with said pipe, said surface comprising:

a first surface portion oriented substantially perpendicularly to said axis of rotation;

a second surface portion oriented angularly with respect to said axis of rotation.
