A method for reducing stress at a junction of high pressure fluid flow passages in a body, and a junction formed thereby

摘要

A method for reducing stress at a junction of high pressure fluid flow passages in a body involves making a depression in an inner wall of a primary passage intersected by a secondary passage. The depression is formed to generally surround an outlet of the secondary passage but be spaced therefrom. In one embodiment, the depression is circular, i.e. ring-shaped.
