Q:Flanges of different sizes
If the outer diameter is not big, the bolt hole, the middle diameter and the bore diameter can be unified. If the specifications are different and can not be directly connected, you can use the big head as an excessive.
Q:What is a flange in machining and why is it named?
Seal points between the two flanges, then fasten with bolts. Different pressure flanges have different thicknesses and use different bolts. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed at the two sides of the plane are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges. However, this connection is only part of a device, such as flanges and pumps connected, it is not good to pump the flange parts. Relatively small, such as valves, etc., can be called flange parts.Flange connection is an important connection way for pipeline construction.Flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, between the two flanges, plus flange pad, bolted together, completed the connection.
Q:In the heat exchanger calculation, the actual bolt section area of the cylinder flange is smaller than the required cross-sectional area. What's the matter?
Generally choose JB/T4700-2000 "pressure vessel flange" in the flange, you do not need to calculate
Q:Can you check the anti - tumor drugs from Hongkong to the mainland?
Hongkong can find peak pharmacy, you can mail back to the mainland, very convenient, and I hope to help you.
Q:How much is a bottle of Ma Falan produced in Switzerland?

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:Why use special flange for butterfly valve?
The utility model has the advantages of quick opening and closing at 90 DEG rotation, simple operation, and good fluid control characteristics. When the butterfly valve is in the fully open position, the butterfly plate thickness is the only resistance when the medium passes through the valve body, so the pressure drop produced by the valve is very small, so the flow control characteristic is better.If the butterfly valve is used as a flow control, the main thing is to correctly select the size and type of valve. Butterfly valve structure and principle, especially suitable for making large-diameter valves. There are two kinds of butterfly valves commonly used: clip type butterfly valve and flanged butterfly valve. The clip type butterfly valve is a double headed bolt connecting the valve between the two pipe flanges.
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:How to go from the city to the flange Akailufacun?
You're asking for magic, huh?Go out of the east gate and go to IL village, then go to the right side of the deposit to see a captain, and talk to him,Inside right away, there will be 2 NPC in a note to see one is to Akailufa,.
Q:Who can tell me what "DN" and "PN" mean in flanges, and what does PN16 stand for?
DN----- through the flange -- such as pressure DN15. with Phi 18 DN25. with 32 DN30. diameter pipe pipe with pipe ----------PN----- Phi 38 maximum value, the unit is "MPa, 1 MPa and cm - equivalent to 10KgPN16 refers to the pipe and the flange matched bearing pressure approximately 12 MPa. The equivalent of 120Kg - and cm
