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 48900lb ball valve is greater than theoretical design thickness. In this article, FEM software was used to design ultimate bearing pressure by means of linear stress analysis method. By applying different inner pressure load, the stress distribution of the ball valve was studied. Stress verification lines were draw at stress maximum location and each stress item were checked under corresponding safe value. Optical design obtained maximum inner pressure can provide theoretical support for practical engineering application.
