... internal pressure, and the comparison of the current design codes for buckling design is shown in Table 2 . It can be seen that ASME NH provides design factors for both instantaneous buckling and creep buckling design but no analysis method is provided in this code. Regarding ASME VIII-1, a method based...

... into the behavior of proposed API 12F tanks exposed to higher internal pressure and vacuum pressure. Temporary storage of relatively small amounts of oil upon extraction in the upstream segment of oil and gas industry is typically accomplished by cylindrical aboveground steel storage tanks that are transportable...

... to study, in a comprehensive manner, the stress behavior in internally pressurized cylindrical vessels intersected by radial cylindrical nozzles. The limitation of the shell solution for cylindrical pressure vessels with small-diameter nozzles is addressed by the use of solid elements based on the theory...

... of inelastic response of pressurized piping system under seismic loading. Shake table test has been carried out on a three-dimensional stainless steel piping system under internal pressure and seismic load. The amplitude of base excitation has been increased till failure of the piping system. The tested piping...

... July 10, 2014. Assoc. Editor: Spyros A. Karamanos. 01 12 2012 15 04 2014 An elastic solution of cylinder-truncated cone shell intersection under internal pressure is presented. The edge solution theory that has been used in this study takes bending moments and shearing forces...

... depth and the internal pressure increase and the value of maximum membrane strain in the circumferential direction could be significant depending on the dent depth and internal pressure combinations. The largest value of this strain component was obtained when the internal pressure and the dent depth...

... repaired pipes, especially those subjected to large internal pressure magnitudes. This work is an attempt toward filing the gap by gaining a better understanding of the effects of environmental conditions on the long term performance of composite repaired pipes subjected to large internal pressures. Finite...

.... Ratcheting occurs in a structure subjected to a combination of steady/sustained and cyclic loads such that the material response is in inelastic region. Ratcheting studies were carried out on Type 304LN stainless steel elbows, subjected to steady internal pressure and cyclic bending. The elbows filled...

... to lateral load in addition to internal pressure and axial load. Four full-scale laboratory tests were conducted, and it was found that the application of lateral load on wrinkled pipe produces a wrinkle shape similar to that occurred in a field NPS10 line pipe. Complex test setup was designed and built...

...Jinyang Zheng; Xiang Li; Ping Xu; Xiufeng Lin; Yaxian Li Plastic pipe reinforced by cross helically wound steel wires, namely PSP, is a new plastic-matrix steel composite pipe developed in China recently. In order to understand the mechanical properties of PSP under internal pressure, a four-layer...

...

... and high internal pressures on X52 grade steel pipes with a diameter-to-thickness ratio of 45 show that this pipeline is extremely ductile and did not rupture under axisymmetric compressive axial deformation. However, they fail due to the excessive cross-sectional deformation and the final deformed shape...

...Shinji Konosu; Norihiko Mukaimachi Assessment of the local thin area should be undertaken for both tension and compression bending. In this paper, simplified reference stresses for a flaw in a cylinder are proposed. By using these results, a newly developed p - M (internal pressure ratio...

...Guillermo Ramirez; Michael D. Engelhardt; Timothy J. Fowler This paper proposes a method for determining endurance limits to leakage for fiberglass pipes under internal pressure using acoustic emission signals and static pressure tests. Results are presented from a series of cyclic internal...

...J. Błachut Tests on two internally pressurized toroidal shells are described in this paper. These were laboratory scale models manufactured by welding 90°, 316L steel elbows. The outside diameter of the toroids was about 310.0 mm, radius of the tube was about 41.0 mm, and the wall thickness...
