Hi All,
We are designing our first Div 2 vessel after many Div 1 vessels over the past few years. My question is when it comes to internal support structures for say a demister pad or tower tray how do you approach this? As i understand Div.1 allows you to use generally acceptable rules to...
Im doing a preliminary sizing (my first) of a geothermal fluid collection system from 4 wells to a turbine unit. The design pressure drop is something in the order of 1 - 1.5bar over 2km through the main transmission line. The steam is dry out of the well and im hoping to get some opinion on...
Hi,
We are tieing into an existing steam header that has been in a plant for the last 20 years and has little to no information about it.
I seem to recall that there is a clause somewhere about pressure pipe or equipment that has operated safely in service as being code compliant. Perhaps it...
Hi,
I want to follow Annex B eqn (B.2) and use a direct integration of the isentropic nozzle formula to work out the max flow through a bursting disc orifice.
I understand that the terms come from an isentropic flash at each 'pressure step' through the burst disc but what i dont get is how you...
Hi All,
I have a boiler plantroom with a boiler using 18GJ/h of natural gas. What i want to do is work out a diesel equivalent assuming the efficiency of the boiler is unaltered from running on diesel as the burner fuel (its a dual fuel burner).
My question. Is this a simple case of just...
We want to heat between 3~15L/s of water from 10-50°C using direct steam injection of 225°C 14bar.g superheated steam. This is from a site loop off the back of a power plant turbine.
My question is what issues if any arise from the steam being superheated when it is injected rather than...
Hi,
Recently i have noticed that the ASME VIII Div.1 vessels we manufacture use AS3678 plate for non pressure parts (in lieu of SA-36). We also use AS1548 but of course this an accepted material in II Part D.
I cant find any reference to AS3678 in part II D , but was wondering if there is a...
Hi guys,
Since im relatively new to pressure vessel design im struggling with a concept which i wish to gather some opinions/knowledge on. Specifically in the case of heat exchangers where does the vessel end and where does the piping begin?
What bought this up is we have a shell and tube...
Hello all,
We design pressure vessels to ASME Div.1 usually and have in the past had our AS1210 expert designer to prepare the designs to meet AS1210 criterion as well.
Ive had experience applying other standards for wind action and seismic action , but im unsure as to how to go about this...
Hi all,
we have a vessel design here that is failing in combined loading from wind and seismic action.
It is SA-312 TP316L welded pipe. But unfortunately the purchaser did not specify radiography on the pipe so we have no record of that for the longitudinal seams (2 seams 180° apart on the...
