Deposition of Zirconium Carbide onto a substrate
(North-West University, 2018)he incident at Japan's Fukushima Daiichi nuclear power plant was aggravated by the lack of resistance of the zirconium alloy to steam oxidation. Zirconium alloys have been known to oxidise and produce hydrogen in a steam ... -
Design and assembly of a standard compliant testing facility for locally manufactured industrial valves
(North-West University, 2018)The greatest challenge facing the valve industry, is the access to affordable raw material. With the expected valve increase in South Africa, the industry identified the need for an increase of locally manufactured industrial ... -
Development of a micro burner for the experimental determination of the net calorific value at constant pressure of pulverised coal
(North-West University (South Africa), 2019)Coal combustion remains the major resource of power generation internationally. Coal consists of different substances, which influence its quality and properties. One such property is the calorific value (CV), which specifies ... -
The effect of ovality on the membrane stress in a 2" thick walled 90 deg steam pipe bend
(North-West University, 2018)Pipe bends are an integral part of any pipe work system. Pipe bends are often seen as the weak point in a pipe work system due to the additional stresses that are imposed on a bend during operation as well as the defects ... -
Feasibility of particle reinforcement in the casting of a ductile iron gate valve
(North-West University, 2018)The mining industry relies on gate valves to shut off flow in pipe systems. The demand for, specifically, ductile iron valve housings is steadily increasing in mining applications where cost, wear, and corrosion is a ... -
Residual stress determination of ductile cast iron by means of neutron diffraction
(North-West University, 2018)A study was undertaken to simulate the casting process, using simulation software, of a ductile iron casting (for use as a valve body) and in doing so, to determine the order of residual stress and experimentally verify ...
