在役压力容器环向棱角度检验方法

Proposal of Ring to Edge Angle Inspection Method for in Service Pressure Vessel

压力容器制造中产生的棱角,导致该处的应力集中,降低了压力容器的承载能力,增加了其危险性。作为定期检验的检验机构很难做到制备所有规格的样板,按照现行GB 150规定的测量方法不利于检验机构开展定期检验工作,为此,本文结合笔者多年经验和理论知识总结了一套简单、快速、不需要任何样板的测量棱角度方法。

Corner edge formed in the pressure vessel manufacturing, could lead to the severe stress concentration, reduces the carrying capacity of the pressure vessel, and increases its danger. As a inspection institution for regular inspection, it is difficult to prepare all specifications of sample plate. Current measurement method stipulated in GB 150 is not conducive for inspection institution to carry out regular inspection. Therefore, combining with the experience and theoretical knowledge for these years, this paper summarizes a set of simple, fast, and no sample needed edge angle measurement method.
