Hot-dip galvanized steel is widely used for the construction of underground structures, thanks to presence a zinc coating that able protect carbon substrate through formation corrosion products layer. Soil very complex process and hence it difficult predict resistance specific component because many factors can directly influence behavior material immerged in soil. This work focused on effect c...

Bamboo wells are an economical alternative for water supply wells in developing countries. The design of the bamboo well described in this article was developed based on field tests. Following field experiments, the screen in the bamboo well was fabricated with seven 3-m-long bamboo strips, each 2 cm wide and 1 cm thick. The strips were bolted on 1-cm-wide mild steel rings spaced 30 cm along th...

Corrosion is one of the important factors in equipment failures. Wall thinning can be used to evaluate corrosion conditions. However, most of equipments are coated with insulations in order to elevate the energy efficiency. Pulsed eddy current (PEC) testing technique can be used to measure wall thinning through insulation. But when the insulation outside is wrapped with galvanized steel, PEC si...

Hydrophobicity on steel-based metallic surfaces provides an advantage in limiting corrosion and debris buildup the surface, thereby, improving substrate performance. An experimental investigation was conducted development of zinc stearate silicon dioxide coatings surface hot-dipped galvanised zinc-coated steel substrates, which could be used to induce superhydrophobicity. Under optimal formulat...
