Molding system for insulated pipe

A system for forming an insulated pipe, the system comprising:

• a first pipe insulation mold having a first mold cavity and a first inner diameter, the first pipe insulation mold being configured to support a pipe such the pipe extends along the first mold cavity and the first mold cavity includes a first annulus that extends circumferentially around the pipe;
• a second pipe insulation mold having a second mold cavity and a second inner diameter, the second pipe insulation mold being configured to support the pipe such the pipe extends along the second mold cavity and the second mold cavity includes a second annulus that extends circumferentially around the pipe, the second inner diameter being greater than the first inner diameter;
• and
• one or more injectors, said one or more injectors being configured to inject a first polymer into the first mold cavity for forming a first layer of insulation on the pipe in the first annulus, said one or more injectors being further configured to inject a second polymer into the second mold cavity for forming a second layer of insulation on the first layer of insulation.
