在对管道开孔补强作一般性介绍的同时,着重论述了椭圆形补强圈的实用性及经济性。通过主管φ720×9、支管φ630×8开孔补强圈厚度的计算,对不同开孔尺寸的管子采用何种类型的补强圈,发表了看法。

With the general introduction of pipeline tapping reinforcement, this paper emphatically explains the practicality and the economicality of elliptical sized reinforcement ring. By the calculation of the thickness of reinforcement ring tapped on 720×9(mm)main line and 630×8(mm)branch line,it expreeses the more realistic standpoint on how to sellect the types of reinforcement rings according to the different tapping sizes of pipes.
