The ground state properties of WC binary compounds (h-WC, c-WC, α-W2C, β-W2C, γ-W2C, ε-W 2C) are studied in this paper by using first-principles calculations. Formation enthalpy and cohesive energy for each phase are calculated. The calculated elastic constants satisfy the BornHuangs stability criterion, indicating all studied compounds are mechanically stable. All WC compounds studied in this paper exhibit larger bulk modulus values than many other binary types of carbide such as Fe3C, Cr7C3, Cr 3C, and TiC. Using a theoretical method based on the works of Šimůnek, the hardness of the crystal is estimated. The electronic structures of these compounds are calculated and discussed. Stoners polarization theory for itinerant magnetism is applied to explain the observed paramagnetic behavior of the compounds. Moreover, the heat capacity is also calculated for each compound based on the knowledge of the elasticity and Debye temperature. © 2010 Elsevier B.V. All rights reserved.

Pipelines 2014: From Underground to the Forefront of Innovation and Sustainability - Proceedings of the Pipelines 2014 Conference | Year: 2014

Zinc metallizing with a high-purity zinc wire has been utilized for external corrosion control of iron pipe for more than 50 years. This paper summarizes publications and experiences of metallized zinc on iron pipe over that time period and discusses advantages and limitations of this method of corrosion protection. Advantages include but are not limited to uniform cathodic protection of the iron pipe surface; thicknesses compatible with critical joint tolerances; no special considerations with respect to field cuts, tapping saddles, or corporation stops; no special handling or installation procedures required; ability to «self-heal» in many environments; minimal surface preparation required; and compatibility with current ductile iron pipe manufacturing processes. Limitations include that it is not recommended as a standalone method of corrosion control in severely corrosive soils or areas of stray electrical currents, it has limited cathodic protection at large areas of unrepaired damage in that it is a sacrificial coating that sacrifices itself to protect the iron substrate, and it is not compatible with some polymeric topcoats. In severely corrosive soils or areas of stray electrical currents, polyethylene encasement conforming to AWWA C105 is used to supplement the metallic zinc coating. Previously unpublished results of corrosion studies, with and without polyethylene encasement, are also presented. © 2014 American Society of Civil Engineers.

This paper presents an experimental investigation into the influence of winding angles in multiaxial ultimate elastic wall stress (UEWS) tests of glass-fibre reinforced epoxy (GRE) composite pipes. Currently, UEWS test is one of the alternative methods used to the 1000-hour test procedure detailed in ASTM D2992 for the detection of manufacturing changes and reconfirmation of the design basis of composite pipes. A stress-strain response was obtained for each winding angle and the results then compared with those computed through conventional laminate theory. Experimental data showed that the UEWS point varies for each winding angle, and the difference becomes even more pronounced, especially when the angles deviated from the ideal ±55°. It is also concluded that the UEWS stresses, which represent the onset of non-linearity were very much dependent on the transverse and shear stress responses, and these values were found to be consistent with the predicted values from the commonly used Tsai Wu failure criterion. © (2013) Trans Tech Publications, Switzerland.

For a number of years, an analytical model of particulate slurry flow has been under development at GIW Industries, USA, while large bodies of experimental data, including concentration profiles, were obtained at the Saskatchewan Research Council, Canada, and other laboratories. The present paper amalgamates information from these sources, showing that the analytic predictions match the observed concentration profiles. © 2009 Elsevier B.V. All rights reserved.

TAMPA, Fla.--(BUSINESS WIRE)--Heat Pipe Technology (HPT), a division of MiTek® Industries, announced that it has opened a new laboratory at its Tampa location, dramatically expanding its ability to research, develop, and test new products, while expediting the time-to-market for such products. With 3,800 square feet of new testing and research space, HPT now has the capability to test to the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) Standard 1060. Indeed, HPT’s facilities are comparable to those offered by Intertek (AHRI’s official test agency) for Energy Recovery Ventilator (ERV) testing. Although HPT’s products may still be subject to the third-party AHRI testing and approval process, HPT can now pre-test its products to AHRI standards. This not only dramatically compresses the product development cycle-time, it also opens up more time and capability for HPT personnel to create new product innovations. Situated on-premises, the new state-of-the-art HPT lab is fully equipped to support heat pipes testing up to 16 feet in length. With a robust automation and data-acquisition system, this facility offers the capability to run tests overnight and on weekends without human oversight. “This new lab is a quantum leap in capability for HPT,” said HPT’s Dr. Onieluan (“Tam”) Tamunobere, a resident scientist and engineer. “Our capability to innovate has been expanded, and our time to move innovations from concept to market has been compressed to a fraction of what it was before we had the lab.” Heat Pipe Technology, a division of MiTek®, a Berkshire Hathaway company (NYSE: BRK-A, NYSE: BRK-B), is the innovation leader in passive energy recovery and dehumidification systems for commercial and industrial applications around the globe. Employing the very latest in passive-heat-transfer technology, Heat Pipe Technology designs and supplies the core energy recovery technologies to the world’s leading commercial air-handling equipment manufacturers.
