Danger of Hanging Slit Coils by Pipe@@@@HOME@ZpΏΊ @Zppκ @If slit coils are hung by pipe as in the right figure, there will be high risk of buckling in the pipe, unless the pipe is strong enough. The stress in the pipe can be calculated as below. @ |

@Slit coils should be considered to give an independent load to the pipe, even if they are strapped together. @The maximum stress in the pipe can be calculated by the following formula. |
