Abstract
Roll grooved pipe fittings useful in the assembly of a variety of mechanically joined piping systems. These pipe fittings are roll grooved so that they can be mechanically joined directly with other like pipe fittings and/or with roll grooved straight pipe thereby substantially simplifying assembly. In addition, hybrid pipe fittings and systems are also disclosed. Methods and apparatus for manufacturing these aforementioned roll grooved pipe fittings are also disclosed and address both the roll grooving process itself, as well as various methodology and apparatus for correcting deformations that can occur as a result of the roll grooving process. Methods for using the aforementioned apparatus are also disclosed.
Claims20
A method of manufacturing a roll-grooved forged carbon steel fitting, the method comprising:
- obtaining a forged carbon steel fitting, the forged carbon steel fitting comprising a tubular structure having one or more bends associated therewith;
- placing the forged carbon steel fitting onto a roll grooving apparatus;
- installing a leverage bar onto the forged carbon steel fitting;
- and
- roll-grooving the forged carbon steel fitting in order to produce the roll-grooved forged carbon steel fitting;
- wherein the installing of the leverage bar onto the forged carbon steel fitting comprises installing the leverage bar such that a portion of the leverage bar rotates about an axis that is collinear with an axis of rotation for the roll grooving apparatus.
A method of manufacturing a roll-grooved forged carbon steel fitting, the method comprising:
- obtaining a forged carbon steel fitting, the forged carbon steel fitting comprising a tubular structure having one or more bends associated therewith;
- placing the forged carbon steel fitting onto a roll grooving apparatus;
- installing a leverage bar onto the forged carbon steel fitting;
- and
- roll-grooving the forged carbon steel fitting in order to produce the roll-grooved forged carbon steel fitting;
- wherein the installing of the leverage bar onto the forged carbon steel fitting comprises securing the leverage bar adjacent to a peripheral opening of the forged carbon steel fitting.
A method of manufacturing a roll-grooved forged carbon steel fitting, the method comprising:
- obtaining a forged carbon steel fitting, the forged carbon steel fitting comprising a tubular structure having one or more bends associated therewith;
- placing the forged carbon steel fitting onto a roll grooving apparatus;
- installing a leverage bar onto the forged carbon steel fitting;
- and
- roll-grooving the forged carbon steel fitting in order to produce the roll-grooved forged carbon steel fitting;
- wherein the installing of the leverage bar onto the forged carbon steel fitting comprises securing the leverage bar to a central location of the forged carbon steel fitting, the central location being disposed away from open apertures for the tubular structure.
