OBJECTIVES To evaluate exposure to lead and other metals from drinking water as a result of the materials used for pipes in the supply areas of the Basque Country (Spain). METHOD Random sampling of properties in the supply areas was carried out. A total of 3,295 samples were taken in 154 areas, which together represented 87% of the properties supplied in our region. A method known as random d...

In piping the defects play a key role for determining the life of component. Also the risk for pipe failure combined to the defects has to be taken into account. In this study thermal dynamic load has been applied to austenitic material (Aisi 304) in order to introduce dynamic behaviour into the crack. The studied crack (~20 mm ! 7 mm) has been produced by thermal fatigue in advance. Different ...

Seepage failure in the form of piping can strongly influence the stability of block-in-matrix-soils (bimsoils), as well as weaken and affect the performance of bimsoil structures. The multiple-factor evaluation and optimization play a crucial role in controlling the seepage failure in bimsoil. The aim of this study is to improve the ability to control the piping seepage failure in bimsoil. In t...

Cohen, Alexander J. M.S., Purdue University, December 2014. Using Individual-based Modeling to Explore How Environmental and Anthropogenic Factors Impact Piping Plover Breeding Success. Major Professor: Patrick A. Zollner. The Piping Plover (Charadrius melodus) is an intensively managed shorebird species which breeds in part along the Atlantic Coast. Major threats to Piping Plovers include habi...

Plastic piping made of polyvinyl chloride (PVC), and chlorinated PVC (CPVC), is being increasingly used for drinking water distribution lines. Given the formulation of the material from vinyl chloride (VC), there has been concern that the VC (a confirmed human carcinogen) can leach from the plastic piping into drinking water. PVC/CPVC pipe reactors in the laboratory and tap samples collected fr...

Although the concept of concurrent engineering has been widely applied in the manufacturing industry, there is growing awareness and interest in the adoption of Concurrent Engineering (CE) in the Construction Industry because CE has the potential to make construction projects less fragmented, reduce project duration, improve project quality, reduce total project cost and increase project compet...

ii) The control valve Manufacturer can only state the Inherent valve characteristics, which refer to the flowrate (F) – valve travel position (m or Z) relationship, when the pressure drop across the control valve (DPV) is constant. Note that the pressure drop across the control valve (DPV) can be almost constant only if the piping system pressure drop (DPS) is concentrated at the control valve ...
