KaMoen, That's a great idea! -typically it's been "one man - one data sheet", but both NORSOK (some Norwegian stuff) and ISA does give smaller companies not using INtools (or similar software) the possibility to at least communicate at an early stage what they intend to supply.

Hi, I've tried to find a standard type valve data sheet (similar to ISA-TR20.00.01 for instruments) - without luck. Doesn't seem to be any in the ASME selection either. Is there anyone out there who can point me in the right direction? Any help will ofcourse be highly appreciated! Regards, Odd

Hey, it's what I would call a pitot. So is this considered to give better accuracy compared to a us flowmeter? Btw, what does 'Mag' actually mean?

MAG for crude? -It must be quite some special MAG tube.

As nylon is a non-newtonian fluid (viscoelastic), I guess you cannot use the reynolds as you would do for a newtonian fluid? -or can you assume that the 'flow conditions' are similar to those of a newtonian fluid and thus use the reynolds as we know it?

If you're into a BV project, you have to check their rule on the subject (NR216). But I don't think that anybody will be too happy with cracks. How far east in europe is your supplier located? -you might also check for any traces of radioactivity as well...

Hi, Unfortunately, I got no response on this forum but found one I can use; a Cooper Course-Hinds gland, model: TUCFS. It’s with sealing compound to meet IP68 up to 100m. Liar

Hi, Typically you have to use materials supplied by a BV approved supplier. Or if not, a local BV inspector goes to the supplier and approves the 3.1 certificate and it then becomes BV approved. I've also experienced that the local BV surveyor will have the 3.1 certificates presented locally...

Oops, I forgot: I'm basically looking for a gland that don't require compound filling.

Hi, I need a cable gland as follows for some instruments: -M20 threads -Cable OD: 10-13mm -IP68; 40 meter for 30 mins (=trouble for most suppliers) -SS 316 -Ex e (ATEX) I would be really happy if someone out there could point me towards a potential supplier of such (I've checked CMP (turned...

DIN 11850.

I think you have a DIN pipe with OD 154mm / ID 150mm (wt=2mm) with a collar and then this lapped flange fitted. A company I knew once use DIN pipes with the appropriate DIN collar and then EN 1092 flanges (typical bore for this size will be 170mm (PN16)), ensuring that any non-circular pipe...

Use ISA-5.1. Try to avoid using 'local' standards even if it can be tempting as many a local 'hero' has injected it into his brain. http://www.isa.org/Template.cfm?Section=Standards2&template=/Ecommerce/ProductDisplay.cfm&ProductID=2636

Okay, but back to the flow; as there is no mass transfer, there is no flow. So the answer must be that there is no flow (ie no movement of mass) between the tanks. Or?

I think that you actually have no flow. As you have two completely full tanks of water (assumed non-compressible in this case), you system is completly filled and you're not able to get any movement of mass. Is this a question raised in some IQ test or am I completely off the track??

Gents, My question is only if it's allowed by code to do modifications. In my opinion it's not. And for gods sake, I don't machine these flanges in my garage (or in China for that sake). It's a sub-supplier having some clever idea that he's struggling to give me some good support on.

Hi there, I have a supplier of a component with 4" WN ANSI B16.5 600# RJ flanges. In order to reduce the overall lenght of the component, they reduce the lenght through the hub from stated 4 inch to 3.15 inch, thus saving a total of 1.7 inch on the lenght. The machine new welding ends, seems to...

Chocked flow (or critical flow) for a liquid is when the mass flux through a restricted area (=critical area) is at its maximum (velocity is sonic). So, if you decrease the downstream pressure, the mass flow will not increase. It does not mean that flashing / cavitation occurs, only if the...

Your I/P converter converts I (current) into P (air signal). So, when the system (PLC) gives a analog output based on 4-20 mA and you have a pneumatic operated valve, you use the I/P converter to convert current into air (typical 3-15 psi). A valve positioner can be pneumatic (and then you need...
