Wonder if anyone can advise as to what the 'proper' P&ID symbol for a metering / dosing pump might be? Struggling to find much on-line but did find the attached link on 'Northridge Pumps' site.
Is this symbol in general use for metering pumps?
(Background is I have a load of clients P&ID's...
Is there a definitive document / publication I can refer to to give me up to date and accurate materials equivalents between the various national standards? ASTM to DIN to BS EN etc.
I've found a number of manufacturer's tables and comments online but this being the 'internet' I'm not sure that...
We've been specifying and using the proprietary Deepwater I-Rod and NuBolt system as an aid in minimising crevice corrosion at pipe support locations. Generally successfully. https://stoprust.com/i-rod-pipe-supports/
But a question has arisen with regards to possible static build-up (due to the...
The 2007 edition of BS EN 1092-1 had a National Annex with guidance on P/T ratings for S235JR flanges.
The 2018 version of BS EN 1092-1 has had the P/T National Annex removed.
Does anyone know how the P/T rating is now determined for S235JR (1.0038), Group 1E1 material flanges?
A question with regard to the applicability of the Pressure System Safety Regulations.
As many of you will be aware, one of the criteria for the PSSR to fully apply, is the is the 'bar x litre' value to be 250 or greater.
My question is, can you 'lower' the capacity value used in this...
We traditionally have specified a B7/2H combination for 'normal' piping operation (typically up 20 bar and ambient temp. conditions).
We also have a 'low temperature' requirement where the minimum temperature can reach -42degC (-44degF).
In these 'LT' conditions, we have typically specified...
Hi all.
Does anyone have any 'worked examples' of the the sustained load calulations in para 320.2 that they might be able to share or 'signpost' me towards?
I'm not talking about a 'Ceasar' print out, rather a typical 'manual' example of how the calcs work?
Many thanks.
Could I ask, what national / international standards are people using for design of pipe supports?
In the UK we had BS3974 but this is long withdrawn but not, as far as I can tell, not been replaced.
I’ve also seen reference elsewhere to ANSI MSS SP-58. Was wondering if this is a suitable...
I've been tasked with updating a UK Company's process piping spec. This hasn't been done for some time and numerous 'BS' references are 'out of date'. With regard to check (or non-return) valves, these are specified as needing to be to:
- BS 1868 Specification for steel check valves (flanged and...
