Abstract
A method and apparatus for straightening a casing is provided herein. The method can include securing a casing in a pipe end straightener, where the pipe end straightener includes a mounting platform, an analog feedback device, and a hydraulic press. The method can also include measuring one or more characteristics of a bent portion of the casing with the analog feedback device. The method can also include straightening the casing by applying a calculated force to the casing with the hydraulic press.
Claims20
A method for straightening a casing, comprising:
- securing the casing in a pipe end straightener,
- wherein the pipe end straightener comprises:
- a mounting platform,
- a headstock and a rotatable headstock plate connected thereto,
- an analog feedback device mounted directly to the headstock plate, and
- a hydraulic press, and
- wherein the casing comprises a bent portion and a straight portion;
- establishing a center axis of the straight portion,
- moving the analog feedback device around the outer surface of the bent portion by rotating the headstock plate, wherein the analog feedback device takes measurements of one or more characteristics of the bent portion in relation to center axis of the straight portion;
- and
- straightening the casing by applying a calculated force to the casing with the hydraulic press.
8 more elements
A pipe end straightener, comprising:
- a mounting platform configured to secure a casing;
- a headstock;
- a rotatable headstock plate connected to the headstock;
- an analog feedback device mounted directly to the headstock plate and configured to move the analog feedback device around the outer surface of the casing by rotation of the headstock plate, wherein the analog feedback device takes measurements of one or more characteristics of the casing;
- a program logic controller configured to analyze the characteristics of the casing and calculate a force to apply to the casing;
- and
- a hydraulic press configured to apply the calculated force to the casing.
4 more elements
A pipe end straightener, comprising:
- a mounting platform configured to receive and secure a casing;
- a headstock;
- a rotatable headstock plate extending from the headstock;
- an analog feedback device mounted directly to the headstock plate and configured to move the analog feedback device around the outer surface of the casing by rotation of the headstock plate, wherein the analog feedback device collects data and wherein the collected data comprises one or more pre-selected characteristics of the casing;
- a program logic controller, configured to analyze the collected data to determine the angle of bend in the casing and to calculate such force required to straighten the bend;
- and
- a hydraulic press configured to apply the calculated force to the casing.
