Prolonging the Service Life of steam lines
Thermal Engineering, 2000Co-Authors: B. D. Dityashev, A. B. Popov, V. G. ShmachkovAbstract:The necessity of a special examination of steam lines, whose Design Service Life has nearly expired, is substantiated. Based on the results of this examination, a diagram for calculations of this steam line, wherein all of its Design features are taken into account, is formed. The results of calculations by this diagram are employed in substantiating how long the steam line can be further used, and in revealing its most stressed components, which are then checked by other methods.

Securing reliable operation of pipelines at thermal power stations
Thermal Engineering, 2000Co-Authors: P A AntikainAbstract:A review is made of normative and technical documents that determine the system of quality control of the Design, the manufacture, the installation, the operation, and the repair of pipelines at thermal power stations and heating boiler houses. Concise information is given about the level reached in reliable operation within their Design Service Life and after it has expired.

ensuring reliable operation of boilers vessels and pipelines after their Design Service Life has expired
Thermal Engineering, 1996Co-Authors: P A AntikainAbstract:In order to prolong the Service Life of equipment, a strength analysis should be carried out that accounts for the actual operating conditions and geometry of the given element, as well as the operating conditions that are planned during the added Service Life. Recommendations for improving the system of normative documentation are given.

The influence of regenerative heat treatment on the properties of steel 12Kh1MF
Thermal Engineering, 2001Co-Authors: V. F. Zlepko, K. R. Linkevich, T. A. ShvetsovaAbstract:The problem of extending the Lifetime of steam lines made from chromium-molybdenum-vanadium (Cr-Mo-V) steel after their long-term Service is analyzed by carrying out regenerative heat treatment (RHT) directly at power stations. Positive experience in operating such steam lines at many power stations confirmed the expediency of carrying it out on the steam lines at thermal power stations whose Design Service Life is depleted.

advancements of new narrows suspension bridge Design in tacoma washington
Transportation Research Record, 2008Co-Authors: Kenneth Serzan, Thomas SpothAbstract:The suspended superstructure of the new Tacoma Narrows Suspension Bridge in Washington State consists of twin welded steel trusses with a continuous and integral orthotropic steel deck measuring over 1 mi in length. AASHTO M270 Grade 50 HPS 50W and HPS 70W steels are the materials of choice. The truss elements are fabricated of both closed-box and open I-sections. The bridge, including major components of the stiffening truss, was Designed to allow for a future lower roadway or light-rail transit system. This paper discusses the Design aspects of this 5,400-ft suspended superstructure, including the development of Design details to satisfy performance requirements for Serviceability, fatigue, wind, and seismic loading. Global superstructure and local component computer modeling techniques are presented as they relate to force, fatigue, and displacement demands and overall structural performance for the 150-year Design Service Life. Fabrication and lessons learned are also discussed.
