ABSTRACT:
A self-contained trailer mounted proportioning, mixing, injection and collection system enables pipelines to be conveniently coated in-situ using two-component coating compositions moved through the pipeline by a double pig system without solvent vapor exposure, liquid spills or drips, undesired air bubble formation in the coating composition or exposure of operating personnel to pressurized gas, solvent vapors or liquid coating material splash or hazardous flammable or explosive conditions.
