I wondered if anyone could help.
I understand that the guidance under BS PD 8010 instructs hydrostatic testing to last for 24 hr. I need to get hold of a copy of this standard but I'm not sure which part contains the testing info.
There's 4 parts. Anyone know?
I have a process gas operating at around 210 deg C in the pipeline. This will then pass into a valve, which has a PTFE lined seat. The flow area in the valve is somewhat less than the full bore of the pipe and so there must be a degree of compression. Now if compression takes places - we must...
Having carried out a few calculations involving multi-phase flow and checked the flow regime; it is beginning to seem inevitable that the flow will be slug flow when following the Gregory-Aziz flow pattern (Superficial Gas velocity 3-80m/s and superficial liquid velocity of 0.3-10m/s).
I had...
I am fairly new to the world of flange standards and was hoping someone could clear up a point of confusion for me. A client has requested BS EN PN64. I understand this standard was replaced with the ISO 1092 PN63?? In this case - would the dimensions match up like-for-like or are there...
I wondered if anyone had any experience of boundary layer separation occuring as a gas flows through a valve internals. Was there serious valve damage? How long could the valve operate in this condition?
If such a condition were to be experienced then the natural thought would be to reduce flow...
