This paper proposes a new finite element method for treating the stress analysis of a piping system under general loading conditions. This finite element method will be referred as the finite ring method, since its elements are ring-shaped. This finite ring treatment is based on the general thin shell theory incorporating shear and distributed deformations along the pipe length. In this paper, emphasis is given to the theoretical aspects of the method. A comparison with other experimental and theoretical results is presented to substantiate the validity of the present method.

Tie-in is a very important step on the final stage of pipe construction. The stress of the tie-in girth weld is really one of the key roles that affect the security of the pipeline in service. In this paper, Finite Element Method (FEM) was used to determine the stress of the tie-in girth weld. The factors of stress of tie-in girth weld were analyzed. The results show that uncovered pipe length, tie-in offset and misalignment were the important factors which affect the stress of tie-in girth weld. The maximum Mises stress and axial stress at tie-in girth weld increased with the uncovered pipe length decreasing and the tie-in offset increasing. The stress also increased significantly with girth weld misalignment, especially for axial stress.
