Guided elastic waves in the frequency range of a few hundred kHz, generated and detected by appropriate transducer arrays, are used to monitor the structural integrity of pipes by comparing their actual state with a predefined reference state. For these purposes, theoretical, numerical, and experimental results are combined to study guided wave propagation and wave interaction with relevant def...

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...

In the presented article, cases of reduction pump efficiency as a result back leakage liquid from annular partitions in plunger-cylinder pair sucker rod pumps are considered, and availability various methods to prevent this is shown. Mathematical equations were obtained minimize energy losses by analytical method, based on this, optimal design option was proposed. Keywords: gas, resistance coef...

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...

Many older homes are equipped with mercury-containing gas regulators that reduce the pressure of natural gas in the mains to the low pressure used in home gas piping. Removal of these regulators can result in elemental mercury spills inside the home. In the summer of 2000, mercury spills were discovered in the basements of several Chicago-area homes after removal of gas regulators by gas compan...

The HP scrubber is an equipment used to separate liquid from gas in the oil and industry. low level vessel one of abnormal conditions scrubber, a blowby event will happen because level. So, controller indicator required prevent system damage workplace accidents. alarm response time calculated order avoid accident. To determine for dynamic process simulation method can be using Aspen HYSYS versi...

The design of electrical wiring and hydraulic/pneumatic piping routes in aircraft is a long and repetitive process which is largely done by hand. Presented in this paper is progress in the development of a knowledge based routing system which automates much of the routing process using intelligent algorithms and interchangeable design rules. The system reads three dimensional CAD models to be n...

Applying the modular technology of developing of the problem-oriented extensions of a CAD system to a problem of automation of creating of the axonometric piping diagrams on an example of the program system TechnoCAD GlassX is described. The features of realization of common operations, composition and realization of special operations of a designing of the schemas of the special technological ...

Two standards that are widely used by many countries in designing offshore gas transmission pipelines American Standard – ASME B31.8, Gas Transmission and Distribution Piping Systems Norwegian DNVGL-ST-F101, Submarine Pipeline System. A thorough understanding of these is vital determining optimal pipeline design to ensure integrity for safe sustainable operations, as well striving economic effi...
