ABSTRACT:
An air gap pipe and a method for forming the same are provided. The air gap pipe includes a non-linear outer pipe and an inner pipe of identical configuration disposed concentrically within the outer pipe. The inner pipe is supported by resilient dimples in the outer pipe. The outer pipe is placed in a condition for receiving the inner pipe by longitudinally cutting the outer pipe in half with a pre-programmed plasma arc or laser cutting apparatus. The two halves of the outer pipe are secured together to provide vents, if necessary, for selective dissipation of heat.
