Study of New Welding Tubular Joint Used For Jacket

摘要

As the stronger desire of human for energy and space, offshore jackets are used more and more for these. As the excellent fluid mechanics feature of the tubular member, it is widely used in jacket structures. According to the introduction of the process of casting steel joint and directly weld joint, this page expounds the advantages and disadvantages of them and put forward a new style welded tubular joint. This paper also gives some advises on dimension control and reducing residual stress. All this contribute to a new way for the building of tubular joint of jacket or other similar structures. By integrating the advantages of casting steel joint and directly weld joint, a new type welded tubular joint was developed with the build-up welding. It is easily to assemble and has low residual stress. Because of its integrity, failure probability will be reduced by using this kind tubular joint in jacket.
