...B. H. Wu; Z. F. Sang; Z. L. Wang; G. E. O. Widera The objective of this study is to investigate the strength behavior and plastic limit pressure of hot-tapped pipelines under an internal pressure load. Two full scale test models were fabricated for the experiment. A three-dimensional nonlinear...

...Z. F. Sang; Y. J. Lin; L. P. Xue; G. E. O. Widera The purpose of this paper is to provide research results for a cylindrical vessel—30 deg lateral intersection with diameter ratio d / D ⩾ 0.5 under increasing internal pressure loading. The results include those from tests as well as from...

...Juksanee Virulsri; Shinsuke Sakai; Satoshi Izumi; Atsushi Iwasaki This paper proposes a methodology for applying a multiobjective optimization to risk-based inservice testing with robustness. The multiobjective optimization is applied to solve the tradeoff between maintenance costs...

...J. Błachut The paper discusses the load-carrying capacity of toroidal shells with closed circular cross section and loaded by static external pressure. Details about the manufacturing, pre-experiment measurements and testing of three, nominally different, steel toroids are provided. Two of them...

...Ying Tan; Vernon C. Matzen; Lixin Yu This paper summarizes the literature on reconciliation of finite element analyses with in-plane bending experiments on piping elbows. It then describes in detail two four-point-bending tests on straight pipes and two in-plane bending tests on elbows...

... by extended power failure. The notice has been attached to the resistance of power generation facilities to severe earthquake. The seismic proving test of equipment and structures in thermal conventional power plant was conducted. Tests were performed to demonstrate the earthquake resistant property...

...Linping Zhao, Graduate Student; Nathaniel M. Beuse, Graduate Student; G. E. O. Widera, Project Director, Fellow ASME Many of the investigations dealing with the determination of the time-to-failure of high-density polyethylene (HDPE) pipes involve internal pressure tests. HDPE pipe, however, can...

... integrity. They also specify requirements for preservice examination, acceptance standards, repairs, replacements, and pressure testing. Each nuclear utility in the United States is required to develop and implement a containment inservice inspection program by September 9, 2001, 5 yr after the initial...

...D. P. Jones, Mem. ASME; J. E. Holliday This paper provides a comparison between finite element analysis results and test data from the Pressure Vessel Research Council (PVRC) burst disk program. Testing sponsored by the PVRC over 20 yr ago was done by pressurizing circular flat disks made from...

... was significantly affected by pressure relief valve (PRV) behavior. During the tests, the PRV operating characteristics were highly variable. Since these valves play a large role in the control of energy accumulation and storage in a pressure vessel, it was decided to study their dynamic behavior in detail...
