Abstract
A process for preparing a coated or thermally insulated plastic coated pipe containing the step of embossing a surface of a thermoplastic wrap on a pipe, wherein the thermoplastic wrap is applied on an outer surface of the pipe. The process can provide a coated or thermally insulated plastic wrapped pipe having features on the surface that are produced in a controlled and repeated manner. Such features can provide benefits, such as, a surface for affixing concrete on the coated or thermally insulated plastic wrapped pipe.
