A modular electric induction heating and coating apparatus and method for coating, heating and/or coating and heating (and vice versa) the exterior surface of a pipe section within a pipe treatment region is provided. The apparatus comprises an interchangeable central main frame assembly removably attached to an outer drive frame assembly on each side of the central main frame assembly. An interchangeable induction coil assembly can be mounted in a coil main frame assembly of the central main frame assembly. The coil main frame assembly can close around a pipe section for electric induction heating of the pipe section within the pipe treatment region via a driver system in a central top drive frame assembly. The outer drive frame assemblies include mounting and rotational drive assemblies for interchangeable coating head cartridges that can coat the section of the pipe in the pipe treatment region.
