    Effects of internal pressure on pipe supports

    Thanks for your answer 1503-44. I am aware that pressure can cause movements, which cause stresses in all directions. My question specifically is, if you can consider for example 10 bar acting downwards on the pipe surface and causing a force on the hanger that is below. I am 99.9% sure this...

    Effects of internal pressure on pipe supports

    Internal pressure is in the pipe that is being held by this support. E.g DN200 pipe with 10 bar inside. My reasoning is that no pressure effects are induced on the clamp, but my question is if they should be somehow evaluated instead (e.g by considering pipe deformation).

    Effects of internal pressure on pipe supports

    I refer to a pipe system that is held in place by pipe supports. Think of a steel structure skid that supports pipe routing by pipe clamps such as this one:

    Effects of internal pressure on pipe supports

    From my understanding, internal pressure produces no forces on pipe supports. This is because internal pressure is fully balanced by the tensions in the pipe (hoop stress). If I want to consider an effect, can I do it by assuming a forced displacement on the clamp stem due to radial expansion...

    Stress Analysis of thermoplastic piping (PVDF, PP)

    Dears, I have recently posted similar requests on the following forums: - Pipelines, Piping and Fluid Mechanics engineering: Link - ASME (mechanical) Code Issues: Link Since apparently CAESAR II doesn't support ASME NM codes, how can I use it to perform Pipe Stress Analysis on PVDF piping...

    ASME B31.3 - Flexibility Analysis of Piping in Thermoplastic materials - NOT COVERED?

    Dear all, In chapter VII of ASME B31.3 it is clearly written that methods of stress analysis [highlight #FCE94F]are less well defined for nonmetals compared to metals, because stress-strain behaviour of most nonmetals is different[/highlight]. I need to perform Pipe Stress Analysis for PVDF...

    Pipe Stress Anaylsis on Thermoplastic (PVDF, PP) - applicable US design codes

    Thank you both 1503-44 and EngrPaper. So I have to assume that a calculation for PP piping (which I have seen issued from a supplier) made on the basis of ASME B31.3 for example calling eq. 23(a) from paragraph 320.2 chapter II (which pertains metal materials), isn't the "proper way", right...

    Pipe Stress Anaylsis on Thermoplastic (PVDF, PP) - applicable US design codes

    Dear all, I will soon have to start learning Pipe Stress Analysis in order to be able to perform such calculations for my company. We are water treatment plant producers and we work mainly with thermoplastic materials (PVDF, PP). The preliminary step for me is to have an overview of which are...
