Farzadi, A., Sanaei, S.,

In the research presented in this paper, a failure analysis were carried out to identify causes of an incident, which had taken place after an operation to repair a leak in an interstate natural gas pipeline. In this operation, a partial encirclement reinforcement (patch) was welded to the carrier pipe according to an available hot taping procedure, while gas was flowing in the pipeline. The fa...

in this paper, the behaviour of buried pipelines under the effect of propagation of seismic waves and faulting is studied seperately. the stability of this type of structure was first studied by using three different methods proposed by newmark-hall, kenndey et al. and wang - yeh under the effect of ground faulting. by parametric study, the effect of soil types, size of pipeline, depth of embed...

Offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. Thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. A safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. While the cost...

The present sought to draw a comparison between Model Predictive Control performance and two other controllers named Simple PI and Selective PI in controlling large-scale natural gas transport networks. A nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in SIMULINK® environment of MATLAB®. Control schemes were designed to provide a s...

Submarine pipelines failures lead to oil spills in water and may even lead to explosions with heavy financial and environmental damages. Trawl gear is one of the main factors in the failure of the submarine pipelines. In this paper, sensitivity analysis is performed on influence of height and span length alternations on the response of pipeline against the traction caused by trawling pull-over ...

مشکل ترین قسمت طراحی مبدل آنالوگ به دیجیتال pipeline مربوط به طراحی طبقات اولیه می شود. بطوریکه می توان گفت که دقت طبقه اول، دقت کل مبدل را تعیین می کند. چیزی که در همه طراحی های انجام شده تا به حال مشترک می باشد، dc gain بالا برای آپ امپ بکار رفته در mdac است (البته در مواردی که از کالیبراسیون استفاده شده، الزامی به بالا بردن بهره حلقه باز آپ امپ دیده نمی شود). همانطور که می دانید با زیاد کردن...

Background and Aims: Natural gas pipeline network is an important part of a city’s infrastructure for energy transmission. As the gas pipeline network becoming vaster and more complex, accident caused by the leak of gas pipeline network occur. Accidents consequences caused by gas pipeline rupture, can directly threatening the safety of persons and properties in the city. Thus, it is neces...
