Metal surround square saddle packing U.S.A. Norton that Company develop, its form lies between annular and saddle shape , Therefore there is merit of the two concurrently. The square saddle of metal surrounded the packing and increased the annular muscle on the basis of shape of the saddle on the structure, Have prevented from overlappi-
ngly, has guaranteed certain intensity and rigidity , has gone out of several small claws, Have increased the angry liquid to stir , spread the quality after strengthenning, thus produced unique performance , Abbreviates the packing as special Lip river gram in Great Britain then at home, enjoy very high reputation in the world in square saddle shape of metal. Such new-type high-efficient packing , used for equiping the new packing tower, its height is reduced by 35% than the modes in Chinese operatic music tower, Diameter reduce 30%, raise the effic
iency 10-30% , reduce pressure 20-60% loss. The doing type distillation replaces wet type distillation experimental study and indicates , can reduce 20% of investment at home. In a word, adopting the new-type ringsquare can increase producing rate low energy consumption or cost , Improve the efficiency of separating , the economic benefits are remarkable, this is all of great significance to newly-built chemical petroleum enterprises and old factory's technological transformation . Equipment limited company of the petrochemical industry, ac
