Method of joining pipes and apparatus for facilitating the same
An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.
1. A pipe attaching machine for forming a liquid tight seal between a first distal end of a first pipe and a middle portion of a second pipe, the pipe attaching machine comprising:
a heater having:
a plate having opposed first and second sides, the first side sized and configured to mate with the first distal end of the first pipe, the plate being operative to provide heat to the first distal end of the first pipe for raising a temperature of the first distal end of the first pipe to a softening temperature of the first pipe, wherein the first distal end of the first pipe is defined by an inner diameter equal to an inner diameter of the first pipe and an outer diameter equal to an outer diameter of the first pipe;
a handle attached to the plate, the handle being insulated from the plate so that the handle can be gripped by a person to manipulate the plate even when the plate is heated;
a cap sized and configured to provide a seal with a second distal end of the first pipe;
a vacuum operative to create a negative pressure, the vacuum in fluid communication with a cavity of the first pipe to create negative pressure within the cavity of the first pipe when the cap is mounted to the second distal end of the first pipe to hold the first pipe to the heater when heating the first distal end of the first pipe.

9. The pipe attaching machine of claim 7 wherein the second side of the plate has a concave configuration.
10. The pipe attaching machine of claim 9 further comprising a cup disposed in the second side of the plate, an edge of the cup sized and configured to contact an exterior surface of the second pipe before the concave configured second side of the plate.
11. The pipe attaching machine of claim 7 wherein the heater is operative to generate a temperature between 440 degrees Fahrenheit and 500 degrees Fahrenheit.
