2017 and 2020 will represent major milestones for the light vehicle Diesel engine in Europe and other regions that are committed to WLTP. The Diesel engines’ position as the most efficient prime mover and the need for it to be included in a balanced and aggressive CO2 roadmap is not really disputed. Diesel however faces significant challenges in WLTC / RDE to deliver low ‘real world’ engine out...

Steel-reinforced elastomeric isolators (SREIs) are considerably more expensive than unbonded steel-reinforced elastomeric bearings like those typically used in bridge applications to accommodate thermal expansion/contraction of the bridge deck. SREIs are vulcanized to thick steel end-plates (25 mm or thicker) that are bolted to the supports, while unbonded elastomeric bearings do not have thick...

V. W. Y. Tam · L. Y. Shen · Risk Management for Contractors in Marine Projects ... · pp 403-410 Introduction Marine projects are one of major work in the Hong Kong construction industry. More than forty marine projects are in progress by the Hong Kong government (see Table 1) (Hong Kong Government, 2007), which include bulkheads, seawalls, foundation piles, docks, inspections, piers dredging an...

Methods for estimating structural reliability using probability ideas are well established. When the residual ultimate strength of a buried pipeline is exceeded the limit, breakage becomes imminent and the overall reliability of the pipe distribution network is reduced. This paper is concerned with estimating structural failure of underground flexible pipes due to corrosion induced excessive de...

The safety of lifelines, as the most important urban facilities, under different conditions highly depends on the safe design and performance of these buried structures. This cannot be achieved unless their actual behaviors are well understood and considered at the designing stage. A new physical model was developed in Amirkabir University of Technology to study the behavior of buried pipes und...

Pipe joints have been widely utilized in industrial plants, where dynamic load of vibration is considerably harmful for sealing performance. However, there is a lock of design codes and experimental procedures developed for vibration testing of pipe joints. This paper proposes an experimental setup for testing of pipe joints, which use metal gaskets, in vibratory conditions. Also, a flexible pi...

A tool was developed to aid in ruminal insertion of abomasal infusion lines into dairy cows. The tool consisted of 2 pieces cut from polyvinyl chloride pipe. The first piece of pipe, the insertion tool, contained a groove that held the flexible plastic flange that is on the end of the infusion line. The insertion tool containing the flange was inserted into the ruminal cannula, through the sulc...

An extensive product range is mandatory to be a key player in the pipe insulation market. The polyurethane preinsulated pipe producers are responding to global opportunities by diversifying their activities into industrial, marine, oil and gas applications. Moreover, the requirements for traditional district heating preinsulated pipes including initial thermal conductivity and its ageing perfor...
