Abstract

Fully-welded ball valve has been applied in large oil and gas pipelines, and its quality is directly related to the safety of the transportation of national energy. The wall thickness of 48″600lb ball valve is greater than theoretical design thickness. In this article, FEM software was used to design minimum wall thickness using linear stress analysis method. Though changing wall thickness under design pressure, the minimum wall was 85mm which calculated by linear stress analysis method can provide theoretical support for practical engineering application
