A device for transporting and delivering chemical to interior walls of pipelines employs a pig having a tank which contains pressurized chemical therein. Operably connected to the tank is a nozzle which is equipped to deliver the chemical from the tank onto the inner pipeline walls as the pig is transported through the pipeline. The pig is equipped with a device to deliver the chemical at a predetermined point within the pipeline and includes a position tracking device to enable location thereof. A method of cleaning and treating a pipeline is also provided.
