Looking at 10K Instrument Connections and cannot find an answer to this, hopefully someone here can assist.
Why are BSPP and NPT offered as 10K Fitting Connections but BSPT is not. I'm looking at 1/2" in particular where NPT and BSPT as almost identical in Taper Angle, Pitch, just the Thread...
Fully agree with PeterIgg, Firesafe Certification does not normally have a expiry date, it is made obsolete eventually by changes to the Specifications.
What you may have is a 'Type Approval Certificate', these are issued by organisations like Lloyds Register to show that a product is...
Is anyone aware of any IBR (Indian Boiler Regulation) approved Forgemaster or Foundry in Europe? We need to purchase a small number of Forged Billets or Castings.
Looking for an idea on design spec for 10K fittings, currently using BS3799 for 6K. Vendor is suggesting making Tees/Elbows from Solid bar for 10K, this is not allowed for 6K in the BS but we notice that the likes of Parker mention making 10K fittings from Bar which seems to also cover...
Looking at the original question, some manufacturers offer larger sized Valves with Cast Carbon Steel Closure (Wedge/Disc/Plug) with a 13%Cr Overlay to save cost. So it looks like you are comparing Solid 13% Cr Steel vs Cast WCB with 13%Cr overlay. Hardness should be much the same.
The Solid...
We have recently carried out a Fire Test on Behalf of a Client on a 'Stock' 2" ANSI 150RF Wedge Gate Valve. Around half way through the burn period there was a 'Pop', the Stem Thermocouple dropped slightly and there was a slight 'Roar' from the fire. The Pressure remained constant and...
ANSI/ASME B16.34 has a table A1 which shows the relationship between Valve Bore and NPS. For 2" it states the Valve Bore for ANSI 2500 Rated Valves as 1.5" API 608 states 1.94" regardless of Pressure Class whilst API 6D states 1.69" at ANSI 2500 but 1.94" For all lower classes. MSS SP72...
I'm looking for some thoughts on Material Qualification of Fire-tested Valves according to ISO 10497:2010 and API 607 7th Edition.
We have tested 2" & 6" ANSI 150/600/1500 in Carbon Steel to Qualify 1/2" - 12" ANSI 150-1500. We are now looking at Testing Stainless and Duplex to complete the...

We have recently offered ANSI 2500 Valves to a client in A182 F316L material (As F316L is more readily available than F316). Our client has reject the offer as according to ANSI B16.5 1996 and B16.34 2004 the max working pressure for these materials are 5000psi.
The Valves are manufactured...
BCD do you (or anyone else) have any thoughts on F316 or CF8M. Some of our Suppliers say that they cannot supply valves in these materials below -29 deg C without carrying out Charpy Impact Testing.
Yet I have seen another manufacturer who makes the statement that their valves CF8M / F316...
I have several trainee engineers that we need to start giving some general Valve Training to; Types, Selection, Materials, History etc etc.
Does anyone know of any good Sites that have useful information?
Western European Manufacturer, who only provides a breakdown of the Chemical and Mechanical results on their own cert. However we believe that the casing is of Chinese Origin. We have asked the Lab to take a look at the microstructure. I'll post back to let you all know the findings.
Thanks for your help so far, I have checked the Mill Cert and it clearly states "Normalised and Quenched". I have noticed the following in A352
X1.4.3 The literature shows that notched bar impact strengths in constructional steels differ widely in accordance with many variables. Consequently...
We were recently asked to Validate Charpy Impact Values of an A352 LCC Finished Machined Valve Body Casting. The Mill Certificate gave an average of 24J @-46Deg C with a minimum single reading of 23J.
After taking 10mm x 10mm Samples across the flange (Between the Bolt Holes) and carrying out...

I know for a fact that a company called Ball Valves UK do this spec of valve, although I'm not sure about the 4mm bore.

You need their "RP" series valve.

If it is PBV and your friend is in Europe it is more likely to be "Pibiviesse" in Italy. This was the Original "PBV" valve. Zydell (Zytec) were their distributor many moons ago but there was some kind of dispute over the use of the name and PBV (the Italian Co) became Pibiviesse whilst Zydell...
