摘要
Bend erosion is a fairly serious problem in conveyer pipe system. In this paper a new anti-erosion method for bend: ribbed anti-erosion method was introduced. An experimental research was done by fixing ribs in the range of 10°-70° on the outer wall of inside 90°-bend. As a result, the anti-erosion efficiency 93.02% was obtained in the experiments. It showed that ribbed bend technology is a simple and efficient anti-erosion method. Besides, it was found that rectangular ribs have more obvious anti-erosion effect than square ribs do when they have equal height.
