                      錫青銅棒=直徑×直徑×0.0068×Lm

                      管材

                      不銹鋼管=(外徑-壁厚)×壁厚×0.02491×Lm

                      =(外徑-壁厚)×壁厚×0.02466×Lm

                          =(外徑-壁厚)×壁厚×0.0087965×Lm

                      =(外徑-壁厚)×壁厚×0.02697×Lm

                      =(外徑-壁厚)×壁厚×0.02796×Lm

                          =(外徑-壁厚)×壁厚×0.03572×Lm
