No, BigInch, thanks but I could not find there what I am looking for... I think wherever I can find a 6" class 300# gate valve for oil service, I will find the whole stuff. Any other suggestion? I'll keep on searching... Thanks, Heyner

Hi everybody! Does somebody know where can I find CAD 2D free downloadable drawings of valves and fittings? what I need now is just class 150 and 300 ANSI fittings... gate valve, globe valve, check valve, WN flanges, elbow, tee, and so on... for oil field application... I've been looking for...

Oops, I was not clear... The point is I have to live with a mixed (ASA ISO) existing construction and some of new supplies are available only ASA or ISO. I'm not trying to MIX, I'm trying to survive! Since I've been working always as per American Standars, I'd like to know the ISO standars...

Hi everybody! I'm working in a project which involves supplies from USA & Europe (ANSI, ASTM & ISO, DIN standards), so I'd like to have a cross reference, for instance: If I have ANSI B16.5 for Flanges, which the ISO standard for these components? (I know an ANSI flange doesn't match an ISO...

I have a datasheet of a tank to be designed per API 620 standard, and it shows +700mm H2O and -100mm H2O as design pressures. Reading scope at API 620 (1.2.2) I can find 15 psi as maximum internal pressure, no clue about external pressure. I remembered then that API 650 address for a maximum 1...

1st: Yes, I did it. 2nd: Yes, I did it. 3rd: My customer only knows he needs a door. 4th: It sounds useful. How can I get it? I just want to have a start to avoid the risk of major mistakes, you know, I have never designed a door like this. Thanks for your tips. Regards, Heyner

Anybody?

Tell me if the last reply did work. If it didn't, may be I can take a part of a routine I wrote, hopefully it will. Heyner

Does anybody know where can I find tips, specs, ideas, etc for designing this kind of doors, regarding to mechanical issues as power requirements, velocities, mechanical systems and so on...? I'm about to begin a design... Thanks in advance, Heyner Garcia

Hi everybody: I want to know if there's a recommended maximum leakage rates for sluice and radial gates, according the application, let's say: I'm working on a set of gates for a project consisting in carrying water from one river into another. I think this maximum leakage level is not as...

Very important tip, thanks! Heyner

Hey, thanks again, it is a great tip! Heyner

I see, think it is the key: service temp. Thanks, Heyner

Is it possible to obtain mechanical properties (yield point, resistance, elongation, etc), or some of them, even approximately, by knowing the chemical composition of a steel plate? In this case it is a very low carbon steel, used to build a galvanizing pot, and its compositions is(%): 0.04C +...

Ok, I found in ASME BPVC (SA-20 cause SA-516 address to it) the mandatory requirements, and what to do if normalizing is needed. But my question is How can I be sure I need (or I don't) normalized plates? Is it like JStephen said, at low temperatures? Is it only one of the reasons? Thanks for...
