Q:The connection between the air outlet and the air duct can straddle the flange
Can not.The air outlet must be connected directly to the air duct. If the size of the air outlet is larger than the length of the air duct, a suitable length of air duct must be made to facilitate the connection of the air inlet.
Q:Where is the difference between the double flange limit expansion joint and the double flange transmission joint?
From the model:Double flange limit expansion joint is VSSJA-2, referred to as B2F; double flange transmission joint is VSSJAF, referred to as C2FFunctionally:Double flange limited telescopic joint is mainly used in the allowable displacement range absorb axial displacement and axial pressure pipeline thrust, loose connection is especially suitable for the pipeline vibration or have a certain inclination and turning in. It can prevent the pipeline due to excessive displacement caused leakage and damage compensation joint.
Q:60 seamless steel tubes with 50 flanges, right?
On the next floor, the DN50 seamless pipe has an outer diameter of 60.3 and a flange with DN50. Of course, corresponding to their thickness of SCH? The same thing.
Q:Hole is a through hole on the flange surface?
Flanges in the narrow senseFlange (Flange), also called flange or flange plate. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe.
Q:I would like to ask you master valve has a pair of clamp and flange connection,
To clip type, general caliber is small, pressure is not big. Flanges are suitable for large bore, and others have been answered
Q:Flange diameter 190, diameter 80 is a few inches of 5
How do you calculate the size of the flange?,This is not we can calculate and design, flange design and production is standard. China's standards are mainly petrochemical standards (SH) and the original Ministry of chemical industry standards (HG), in addition to the national standard (GB). In addition, countries have different standards, and a country may have several standards.How many inches do you calculate?The inch should be in inches, inches in size, 2.54 centimeters in =1 inchesThe flange diameter is 190 and the inside diameter is 80 inchesIt's 3 inches.What's the inside diameter or what?Diameter refers to nominal diameter. Nominal diameter can only indicate the size of the pipe and can not indicate the exact size of the pipe.The same nominal diameter of the pipe according to the pressure level, purpose, material, and its internal and external diameter is not the same (this means the same standard).A simple example is to the market to buy our house water, when you go to the market to buy, businesses will say "4" (read: 4) "this is the nominal diameter, then people will ask you to be thick or thin, this is the same nominal diameter under different tube.
Q:What are the specifications of orifice flanges? Be comprehensive
Appendix A of national standard HG 20592-2009 is marked with only WN (high neck welding flange)Pressure rating PN10~PN160Beside the flow hole socket welding or NPT mouth NPS 15 bearingASME B16.36-2009 American Standard marked WN (high neck flange) and SO (neck flange) twoPressure level 300LB~2500LB no 150LBBeside the flow hole for the 1/2 "NPT age
Q:Dn is 250, Pn25 flange, what is the hole distance?
Flange center hole distance d1=370mmFlange diameter D=425Aperture 30Bolt M27
Q:Flange specification PL20 (B)
Hello, I am Hebei wealthrun Pipe Industry Co. Ltd, we are the production of flange manufacturers, this is a Ministry of chemical industry standard, PL is the flange nominal diameter is 20. B most finger outside diameter.
Q:One side is flat plate and side hubbed flange can be connected to it
The same standards, the same pressure, the same caliber, with these three points can be connected
