发明名称 PROCESS FOR CONTINUOUSLY AND CHROMATE FREE COATING PIPE IN FLUIDIZED BED
摘要 PURPOSE: A process for coating pipes is provided to enable continuously and chromate free coating pipe in a fluidized bed. CONSTITUTION: The process for coating pipes comprises vortex sintering using a powdery, meltable polymer as the coating material. The pipe is first cleaned. A primer is then applied and burnt in using a middle frequency induction spool. Vaporized solvent is removed using a radial ventilation unit, and the pipe is pre-heated using an induction spool. Powder is prevented from clumping together by air shower members and guide plates. A further induction spool smooths out incompletely melted areas, and an air shower is used to pre-cool the pipe surface. Final cooling takes place in a water bath.
