Structure Analysis and Optimize for Larger Diameter Tee Used for Oil-gas Pipeline
Most of the tee used for oil gas pipeline are made by pull,under the inner pressure and other forces from the pipeline,stress concentration will occur at the intersecting line of branch pipe and main pipe,the inner fillet and outer fillet take an important effect on the intensity of the tee.the linear elastic method is used to make a detail study on the relationship between the fillet radius and the maximum stress and deformation,then an optimization to the outer fillet is done to improved the load bearing capacity of the tee.
