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.

Claims (15)

1. A push bench system for sizing a pipe comprising:

a die without rollers 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;

a receiver operable to guide the pipe as the pipe exits from the die; and

the receiver is operable to move and rotate and is operable to bend the pipe after the pipe exits from the die.

2. The system of claim 1 further comprising at least one pipe treatment device.

3. The system of claim 2 wherein the at least one pipe treatment device is selected from the group consisting of an induction coil, a tempering coil, a quenching ring, a drilling machine, a coating machine, a phosphating machine and combinations thereof.

4. The system of claim 1 further comprising at least one pipe inspection device.

5. A push bench system for sizing at least two pipes comprising:

at least two dies having respective openings operable to respectively size the at least two pipes, both of the at least two dies without rollers;

a hydraulic cylinder having at least two rods attached thereto;

the hydraulic cylinder and the at least two rods cooperating with each other to respectively push the at least two pipes completely through the respective at least two dies to respectively size the at least two pipes; and

at least two receivers operable to respectively guide the at least two pipes as the at least two pipes respectively exit from the at least two dies without drawing the at least two pipes through the at least two dies.

6. The system of claim 5 wherein the at least two dies comprise three dies, wherein the at least two rods comprise three rods, and wherein the at least two receivers comprise three receivers.
