Flaring and expanding tools and methods of flaring and expanding tubes and pipes

A flaring tool comprising:

• a flaring block;
• and
• a yoke clampable to the flaring block by a clamping mechanism, the yoke comprising:
• a housing;
• a flaring cone comprising a tapered flaring surface adapted to engage an internal surface of a tube and deform at least the engaged portion of the tube to a flared condition;
• a feed screw movable relative to the housing between a retracted position and an advanced position and operatively coupleable to the flaring cone;
• a biasing member configured to bias the feed screw to move relative to the housing toward the retracted position;
• and
• a handle operatively coupled to the feed screw, wherein rotation of the handle rotates the feed screw.

A flaring tool comprising:

• a flaring block comprising:
• first and second block parts pivotally connected and pivotable between a closed position and an open position, the first and second block parts defining a top surface and a bottom surface of the flaring block;
• wherein in the closed position the first and second block parts define at least one tube hole extending from the top surface to the bottom surface of the flaring block, the at least one tube hole comprising:
• a gripping portion extending partially through a thickness of the flaring block and configured to generally conform to an external surface of a tube and substantially engage the external surface in the closed position;
• and
• a flaring portion adjacent to the gripping portion and defining an outward taper in a direction from the gripping portion;
• wherein the first block part defines a portion of the gripping portion and a portion of the flaring portion and the second block part defines a portion of the gripping portion and a portion of the flaring portion;
• and
• wherein in the open position the portion of the gripping portion defined by the first block part is spaced apart from the portion of the gripping portion defined by the second block part;
• and
• a stop comprising a stop portion positionable across a portion of the top surface of the flaring block, the stop being slidably retained in a groove defined in the bottom surface of the flaring block;
• and
• a yoke clampable to the flaring block by a clamping mechanism, the yoke comprising:
• a housing;
• a flaring cone comprising a tapered flaring surface adapted to engage an internal surface of the tube and deform at least the engaged portion of the tube to a flared condition;
• a feed screw movable relative to the housing between a retracted position and an advanced position and operatively coupleable to the flaring cone;
• a biasing member configured to bias the feed screw toward the retracted position;
• and
• a handle operatively coupled to the feed screw, wherein rotation of the handle rotates the feed screw.
