Hydraulic tube expander and method of use

A method comprising:

• receiving a tube expander comprising:
• a head comprising a plurality of expandable jaws;
• a tool body coupled to the head and comprising a handle;
• a source of a hydraulic fluid;
• a biasing mechanism disposed on the tool body;
• a trigger configured to pivot between a first position and a second position, wherein the trigger is configured to repeatedly pump the hydraulic fluid from the source of the hydraulic fluid toward the expandable jaws based on the trigger pivoting from the first position to the second position and, in turn, expand the expandable iaws, wherein the biasing mechanism is configured to pivotably bias the trigger from the second position to the first position, wherein the trigger is located at a junction of the head and the tool body such that a pistol-type configuration is formed, wherein the pistol-type configuration enables a one-handed operation of the tube expander;
• a fluid pipe path extending from the source of the hydraulic fluid toward the expandable jaws;
• a release actuator operatively connected to a one-way valve in fluid communication with the expandable jaws, wherein the release actuator is configured to open the one-way valve and allow the hydraulic fluid to flow away from the expandable jaws engaging the expandable jaws with an interior of a tube;
• and
• causing the expandable jaws to be expanded based on the jaws contacting the interior of the tube via the one-handed operation of the tube expander.

A method comprising:

• receiving a tube expander comprising:
• a head comprising a plurality of expandable jaws;
• a tool body coupled to the head and comprising a handle;
• a source of a hydraulic fluid;
• a biasing mechanism engaging the tool body outside the tool body;
• a trigger configured to pivot between a first position and a second position, wherein the trigger configured to repeatedly pump the hydraulic fluid from the source of the hydraulic fluid toward the expandable jaws based on the trigger pivoting from the first position to the second position and, in turn, expand the expandable iaws, wherein the biasing mechanism is configured to pivotably bias the trigger from the second position to the first position, wherein the biasing mechanism engages the trigger outside the tool body, wherein the biasing mechanism extends between the trigger and the tool body outside the tool body, wherein the trigger is located at a junction of the head and the tool body such that a pistol-type configuration is formed, wherein the pistol-type configuration enables a one-handed operation of the tube expander;
• a fluid pipe path extending from the source of the hydraulic fluid toward the expandable jaws;
• engaging the expandable jaws with an interior of a tube;
• and
• expanding the jaws within the interior of the tube based on the expandable jaws engaging the interior of the tube via the one-handed operation of the tube expander.
