Q:Flange valve Q41F-16C/P/R mark, specific meaning?
This is standard regulation, according to "JB/T 308 - 2004 valve type programming method" regulation:Q= ball valve4= connection type: flange1= structure: floating ball direct flow channelF= sealing surface material: fluoroplastic-16= nominal pressure: 1.6MPaC= body material: carbon steelP= body material: chrome nickel stainless steel, such as: 304R= body material: chromium, nickel, molybdenum stainless steel, such as: 316
Q:What is the output flange? What's the function?
Flange connection, easy to use, able to withstand greater pressure.Flange flanges are widely used in industrial piping. In the home, the pipe diameter is small, and it is low pressure and can not see the flange connection. In a boiler room or production site, flanges are connected to pipes and equipment.
Q:60 seamless steel tubes with 50 flanges, right?
Yes! But more accurate description is: the outer diameter is 60mm seamless steel pipe, and nominal size of DN50 flange matching connection.
Q:What's the flange surface?
Flange sealing surface has a full plane FF, protruding surface RF, convex M, concave F, tenon surface T, groove surface G, ring connection surface RJ, general concave convex MF, mortise and tenon surface TG, ring connection surface RJ are paired usePL welding plate flange with flange, SO diameter, WN butt welding neck flange; IF integral flange, SW socket welding flange, TH threaded flange; loose flange ring PJ/SE welding, PJ/RJ welding ring flanges; flanges BL, BL (S) lining flange
Q:SolidWorks cannot make a miter flange?
No tangency, tangency, no tangency, sheet metal can not be done
Q:Steel pipe can flange connection, aluminum pipe can flange connection?
Both flanges can be connected. The flange is the joint of the pipe and the pipe.Different media, the choice of flange material is different.You say plastic pipes can also come through flanges. Flanges are usually made of nonmetallic material.Teflon can also be done. The wear resistance of PTFE is chenchen.
Q:What does the 6 11/4 mark on the flange face mean?
These refer to flanges,The 6 refers to DN150, 11/4 to DN32, 3 DN80, 2 DN50, 11/2 refers to the DN40 standard, American Standard so marked
Q:I would like to ask you master valve has a pair of clamp and flange connection,
The clamp valve is not connected to its own way, rely on the pipe on the two flanges to clamp the valve, which is suitable for low pressure pipeline; flange valve, the valve itself with flanges, and the pipe flange butt
Q:What does the Rc-RF in the flange stand for? What do they stand for?
RF indicates the sealing surface RC does not know
Q:In building engineering, what is called "flange" means detailed point?
