    longitudinal stress in pipeline

    The longitudinal strain of a pipeline due to internal pressure only is given by: longitudinal strain = longitudinal stress/young’s modulus poisson’s ratio*(hoop stress/young’s modulus) where longitudinal stress = outer radius *pressure/(2*wall thickness) hoop stress = internal...

    hoop stress calculation

    Hi, I have a question: When calculating the hoop (cylinder) stress in a pipe you use static equilibrium and equate the stress in the wall to the gauge pressure: 2*T*S*1 where S is the hoop stress, T is the wall thickness, 1 is the unit length and then equate it to the gauge pressure times the...

    wave propagation in overhead wires with ground return

    Hi, there's a well known paper called "wave propagation in overhead wires with ground return" you can get it at the link below. I'm trying to understand this paper, but on the second page I'm not clear where equation 1 is from. Can someone point me to a book (name and pg numbers please) or...

    influence of AC power lines on steel pipelines

    Hi, I've been reading papers about the influence of high voltage overhead AC power lines on steel pipelines that run parallel to the power lines in the same right of way (that is near the power lines). The pipelines are coated in a dielectric coating to prevent corrosion and can be above...

    HV tranmission line and substation design to oil & gas industry

    Hi, I have the opportunity to work for a small consulting company that does HV substation and transmission line design to connect industrial customers to the grid. However I would like to end up working in the oil sands industry (higher pay) where as far as i know most of the electrical work is...

    is this a good opportunity?

    Hi, I have a career decision to make. I have an option to work for a twenty something employee electrical engineering outfit that's not in a major engineering city (but is in a very nice city), and whose specialty is doing high voltage (up to 287 kv) transmission line design and substation...

    career decision

    Hi, I have a career decision to make. I have about six years of experience and it's been a mixed bag, without me really developing a very strong expertise in anything. Now I have two options: work for a large EPCM firm (one of the largest in the world) in a major energy center dealing with...

    Control systems: really engineering?

    Hi, I have started to gain some experience in control systems in an industrial environment: programming plc's, creating wiring diagrams, cabinet drawings, selecting SCADA telemetry technologies. Most of this stuff doesn't really seem like engineering, and in fact a lot of companies that do...
