This paper intends to introduce a new antierosion method for bend: ribbed anti-erosion method. Experimental research has been done by fixing ribs in the range of 10°- 70°on the outer-wall of inside 90°-bend. As a result the experiment got anti-erosion efficiency: 93.02%. It shows that ribbed bend technology is a simple and efficient anti-erosion method. Besides, the experiments indicate that rectangle ribs tend to do more obvious anti-erosion effect than square ribs do when they have equal height.展开更多
