The Hot-Plugging Clamp Design of the Petrochemical Equipment Pipeline

摘要

Liquid leaking accidents of petrochemical equipment were always happened in weld joint of the pipeline. In order to deal with the accidents, the hot-plugging technique was adopted. And the clamp design which was the difficult point of this technology must be valued. In this paper, the hot-plugging technique and the structure of the clamp were introduced. And the calculation formula of the clamp thickness was deduced based on the influence of the injecting hole on the clamp and GB150-98. And the results would be the fundament of further study of the hot-plugging clamp design
