Method of paint spraying bores of pipe sections

摘要

The single pipe sections are placed end to end to form one longer tube. The bore of the pipe assembly is sprayed from one end while it is rotated about its centreline. The pipe assembly is placed at an angle so that it shapes upwards away from the spray nozzle. After spraying, several end sections are removed, while the same number of sections is mounted at the front. The number of new sections mounted at the front represents the range of the spraying equipment. The length of the pipe assembly is chose so that practically no spray mist emerges from the end.
