Q:Mechanical flange problems,
The 23 attack drill 24 means with drill out the light hole cylindrical surface depth of 24mm, and then use the screw thread tapping into the effective depth of 23mm, which uses standard gauge M12 can be screwed into the 23mm, however, it should be marked drawings of consultations, the final hole should have 1.5 to 2 times the pitch pitch (M12 is 1.75), is about 3mm of the margin, or even the best teacher is also very difficult to achieve. This is my old fashioned experience for reference.
Q:4 points, 6 points, 8 points is how many caliber (pipe flange) who has detailed form information, thank you!
Nominal diameter mm inch inch (inch), commonly known as our country6 "1/8" -"8 1/4" -10 "3/8" -15 1/2, 4 points20 3/4 "6"251 "1 inches."(32) 1 "+1/4" ----401 "+1/2" inch and a half502 "2 inches"Flange due to different nominal pressure, structural types and installation methods of different thickness and size of different, please refer to the "mechanical design manual", pipe fittings.
Q:Hole is a through hole on the flange surface?
Flange connection or flange connection, is defined by the flange, gasket and bolt connection between the three sealing structure of the detachable connection as a combination of group pipe flange refers to the pipeline installation of piping flange, used in equipment refers to equipment import and export flange.
Q:Steel pipe can flange connection, aluminum pipe can flange connection?
The steel pipe, the aluminum tube and the copper pipe can be flanged connected.Flange connection is the two pipes, fittings or equipment, each first fixed on a flange plate, and between the two flange with flange pad, finally by bolt two flange of a detachable joint tension so closely together.purposeThis connection is mainly used for cast iron pipe, lining hose, non ferrous metal pipe and flange valve, etc., the process equipment and flange connection is also using flange connection.The main feature of flange connection is convenient disassembly, high strength and good sealing performance. When installing flanges, the two flanges shall be kept parallel and the sealing surfaces of flanges shall not be damaged and shall be cleaned.
Q:What does the bottom flange mean?
flange1. flange connectionFlange (flange) connection is an important way to connect 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. Some pipe fittings and equipment have their own flange, but also belong to flange connection.
Q:Can you have a more general idea?
The distance of the flange of the bayonet can not be designed arbitrarily, and the width of the small flange can be shorter than that of the photosensitive component. The whole body of the 4/3 system can be fitted with a full lens through the connecting ring
Q:What is the meaning of flange PL50-16RF
Flat plate steel pipe flanges, hubbed steel pipe flanges. Flange for pressure level is relatively low, the pipeline system pressure fluctuation, vibration and shock are not serious in. Flange welding flange assembly has the advantages of easily on, and the price is cheaper, so it has been widely used.
Q:About the difference between valve flanges RTJ, RF
A valve, the valve is in fluid system, a device used to control the direction of fluid flow, pressure, the piping and equipment within the media (liquid, gas, powder) device can control the flow and the flow or stop. Valve is the control component of the pipeline fluid delivery system. It is used to change the section of the channel and the direction of the medium flow. It has the functions of diversion, cut off, throttling, check, diversion or overflow and pressure relief. For fluid control valves, valve from the simplest to the most various valves automatic control system used in complex, its many varieties and specifications, the valve nominal diameter from industrial piping and instrumentation valves tiny tolarge diameter 10m valve. Can be used for the control of water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal and radioactive fluid and other types of fluid flow, the valve working pressure from 0.0013MPa to 1000MPa ultra high pressure, working temperature from ultra low temperature to high temperature 1430 degrees -270 degrees celsius.
Q:SB 1379-NP15 which flange standard is the flange diameter, pitch, thickness, screw hole number and diameter?
Flange, threaded connection (wire), flange and welding flange. Low pressure small diameter wire connecting flange, high pressure and low pressure big diameter all use welding flange, different pressure flange thickness and connection bolt diameter and quantity are different.According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal pad.1. to classified material of carbon steel, cast steel, alloy steel, stainless steel, copper, plastic, Aluminum Alloy, argon Ge Lek, PPC etc..2., the production method can be divided into forging flange, casting flange, welding flange, roll flange (super type)3. makes the standard can be divided into national standard (Ministry of chemical industry standard, standard oil, electricity standard), American Standard, German standard, Japanese standard, Russian standard, etc..
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,.
