ABSTRACT:
A method of and an apparatus for the internal coating of ducts with a synthetic resin, especially long steel pipes or tubes, in which gas-entrained synthetic-resin particles are passed through the tube while the latter is heated progressively by displacing the tube relative to a surrounding induction-heating coil. Thereafter, a gas stream free from particles is used to clear the interior of the tube.
