Verfahren und Vorrichtung zum Beschichten der Innenfläche von induktiv erhitzbaren Metallrohren mit Kunststoffen

A method of internally coating 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...

Zusammenfassung:	A method of internally coating 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 clean the interior of the tube.
