Stress analysis. The stresses in the tangential and longitudinal direction of the cylinder in the composite and in the liner shall be calculated. The pressures used for these calculations shall be zero, working pressure, test pressure and design burst pressure. The calculations shall use suitable analysis techniques to establish stress distribution throughout the cylinder.
Stress analysis. The stresses in the cylinder shall be calculated for 2 MPa, 20 MPa, test pressure and design burst pressure. The calculations shall use suitable analysis techniques using thin-shell theory that takes into account out-of-plane bending of the shell to establish stress distributions at the neck, transition regions and the cylindrical part of the cylinder.
Stress analysis. A stress analysis shall be performed to justify the minimum design wall thicknesses. It shall include the determination of the stresses in liners and fibres of composite designs.
Stress analysis. Stress analysis shall be performed by the Owner’s Engineer per ASME B31.1. Stress will be reduced via horizontal expansion loops, offsets or expansion joints. Vertical expansion loops are not allowed. Use of expansion joints is allowed, upon approval of design and specification details by Company. It is not the Contractors responsibility to perform a stress analysis.
