Abstract
PURPOSE: To suppress the temperature drop of the pipe body and form the film of an even thickness on the inside surface of the pipe by feeding powder-form resin by gas into the revolving metal pipe, which has been preheated and is disposed level, from its one end then stopping the feeding of the gas and letting the powder- form resin stagnate in the pipe.
CONSTITUTION: A metal pipe 1 is preheated by an induction heater or the like and is mounted to a rotary chuck. Thereafter, it is revolved until a series of works are finished. Next, the suction is started by the blower not illustrated and when negative pressure reaches the set pressure, the powder resin in a pressure hopper 6 is blown from the inlet side 1a of the pipe 1 by secondary air 8 (for about 1W2 seconds). The above-mentioned suction and intake is continued for about 5W15 seconds and when the powder resin is filled uniformly in the pipe length direction of the pipe, the suction is stopped. Next, when the negative pressure in the pipe reaches the atmospheric pressure, the blowing of the powder-form resin is stopped so that the powder-form resin is stagnated for about 15W30 seconds in the pipe 1. Thence, the powder-form resin in the pipe 1 is sucked and is recovered into a sizing machine 7 through a recovery pipe 5.
