Open-pit mining is a comprehensive project covering many aspects. It not only includes common transportation, mining, ventilation, etc. but also provides enterprise management, blasting, machinery, environmental protection and many other contents. Compared with other industries, it's own. There are many unsafe factors, and both the work itself and…
The tankless water heater may be a great solution to this. You can enjoy incredible energy efficiency with these systems along with a variety of other perks. Whether you are looking for a water heater system replacement or you need a new system for a new home, you…
There have been significant advances in recent years in the understanding of bolted-joint behaviour. Past ASME Pressure Vessel and Piping Conferences have seen numerous research papers focused on the topic. Of most interest has been the behaviour of a bolted joint under the action of external loadings, in…
The allowable nozzle load on a tank is a common request; however, the procedure to arrive at an appropriate set of loads is not always straightforward. Firstly, the allowable nozzle loads on a tank are generally significantly different to a similar sized pressure vessel with a nozzle of…
The design of bolted steel tanks to AS2304 is based on a limit states approach which represents a fundamental change in philosophy with respect to traditional tank design. In general, limit states and allowable stress design produce relatively similar results; however, the material savings afforded by the design…
Finite Element Analysis (FEA) has transformed design procedures for engineers. Allowing more complex geometry, loading and restraint cases to be analysed. FEA is a powerful tool for engineers to simulate problems that would otherwise be too cumbersome for hand calculations. It has become more commonplace in industry over…
Our Cairns and Innisfail offices have two new friendly faces at Reception. Kitana Buzacott and Vanessa Colgrave joined the Libretto Solutions team in June through the Queensland Government’s Skilling Q Disagreement between various design standards raises questions for engineers as to what represents an appropriate drag force coefficient…
Large steel stacks and chimneys present unique design challenges to engineers. Given their size, the rules typically used for other structural elements are not necessarily applicable and can potentially result in either uneconomical or unsafe designs. Currently there is no dedicated code to the design of steel stacks…
Transportation of goods by road is an essential part of many industries and is continually growing and evolving. Designers are constantly striving to optimise the tankers to reduce tare weight and increase payload and volume. Improvements in these areas result in less time spent on the road, and…
