1. An apparatus configured for applying pressure to a pipe and measuring internal pressure, comprising:
one or more clamps disposed on the pipe and in direct or indirect contact with a wall of the pipe;
one or more of a first set of strain gauges disposed on an outside surface of the wall of the pipe at an equal distance around a circumference of the pipe;
one or more of a second set of strain gauges disposed on the wall of the pipe at a lateral position corresponding to the one or more strain gauges and at an angle of 0° with respect to a longitudinal axis of the pipe,
wherein each clamp of the one or more claims is disposed circumferentially around a location along the pipe corresponding to the location the first set of strain gauges and the second set of strain gauges; and
a temperature sensor disposed on the wall of the pipe at a lateral position corresponding to the first set of strain gauges and the second set of strain gauges;
where the pipe has an inner diameter, an outer diameter, and a length; and
wherein the temperature sensor measures the temperature of the wall of the pipe.
