Abstract
The present invention involves cost effective, efficient systems and methods for sizing pipe. In an embodiment of the present invention, a pipe sizing system includes a die having an opening operable to size the pipe, a hydraulic cylinder having at least one rod attached thereto, the hydraulic cylinder and the at least one rod cooperating with each other to push the pipe through the die, and a receiver to guide the pipe as the pipe exits from the die.
Claims21
A pipe sizing system for sizing a pipe comprising:
- a die having an opening operable to size the pipe;
- a hydraulic cylinder having at least one rod attached thereto;
- the hydraulic cylinder and the at least one rod cooperating with each other to push the pipe through the die along a longitudinal axis of the die;
- a receiver operable to control movement of the pipe vertically and laterally relative to a longitudinal axis of the die as the pipe exits from the die;
- the receiver operable to guide and shape the pipe as the pipe exits from the die;
- a receiver table operable to move and rotate the receiver;
- and
- the receiver table operable to bend the pipe to a desired shape.

A method for forming a push bench operable to size a pipe comprising:
- installing a die having a longitudinal axis and an opening operable to size the pipe;
- installing a hydraulic cylinder having at least one rod attached thereto and extending from the hydraulic cylinder to push the pipe through the opening in the die along the longitudinal axis without drawing the pipe;
- and
- installing a receiver operable to control movement of the pipe as the pipe exits from the die;
- and
- installing a receiver table operable to move and rotate the receiver whereby the receiver table is operable to bend the pipe to a desired shape.
