I’m in the process of designing a new pipe line using ASME B31.3 and just want some clarification on the analysis of displacement strains/stresses. The code states the following should be achieved:
SE<SA Paragraph 302.3.5
And that SE is calculated as follows:
SE=(Sb^2+4St^2)^1/2 Paragraph...
Our company is in the process of procuring an AMSE code for pressure vessels. We have to decide to procure ASME III or ASME IV as we have a need to use the code on both nuclear and standard Pressure systems. What are the key differences between the codes and is everything within ASME IV covered...
I have some zinc plated fasteners that have seen approximately 5 years of service and the usual policy is to exchange new for old. However timescales are preventing the procurement of new ones and I am looking to perform either DPI or MPI to the fasteners to see if they have developed any...
I have a submersible body that’s about 3m tall and that takes in water from the bottom through three 120mm holes and allows the air to escape at the top through three 50mm holes. I am trying to work out the pressure inside the body, using standard orifice plate theory as described in BS EN ISO...
I am currently performing corrosion trials on naked standard steel test piece for use in sea water. However in service the product will be zinc plated. Does anyone have any guidance on what time offset should be applied to the results with the addition on the zinc coating??

I’m working on a project that requires a metal choice that is relatively resistant to salt water corrosion. I have performed calculations and aluminium (6083) is sufficient but does it perform better then Stainless Steel in Sea water?

I have a bolted blank flange joint and I’m trying to discover an alternative way of finding the load in each bolt when an applied pressure is applied to the blank. Im currently using a circular plate model from Roak’s formula for stress and strain, is it possible to use the energy methods and...
I have spent along while (months) trying to develop an excel spreadsheet to make the extremely complex calculations to design flanges in accordance with EN 1591. I believe I have almost completed this for EN 1591-1, however I cant seem to successfully complete one for EN 1591-3 (metal to metal...
