いた。By the way, the diameter of steel pipes to be coated and the width of steel sheet piles are of various sizes, but the coating capacity of the discharge nozzle is as follows.
Since it is almost determined by the width of the discharge port, when the same discharge width is used, the coating efficiency becomes worse as the diameter of the steel pipe or the width of the sheet pile becomes larger. For this reason, conventionally, discharge nozzles having different discharge widths are used in accordance with the diameter of steel pipes and the width of steel sheet pile, etc., and various types of discharge nozzles are required. Had become.
