System and method for producing spray foam insulated pipe with channels, tubes or conduits

A method of insulating a pipe system comprising the steps of:

• providing a length of a main pipe having an internal surface and an external surface;
• providing a plurality of channels, tubes or conduits attached to the external surface of the main pipe and spaced about a circumference thereof;
• applying a spray foam insulation to the external surface of the main pipe;
• and
• prior to a step of curing the spray foam insulation, applying a compressive force against an exposed outer surface of the spray foam insulation to prevent a bulge from forming over the channels, tubes or conduits so that the outer surface of the insulation has a uniform radius.
