Q:What's the price of a stack of 600 carbon steel flanges?
Beijing Science and technology for you to answer, 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. It is also used for the flange on the inlet and outlet of the equipment, for the connection between the two devices, such as the reducer flange.
Q:Can you check the anti - tumor drugs from Hongkong to the mainland?
You shipped back, no one dared to use it for you? Drugs used by medical institutions should be approved by the state, and if approved by the SFDA, then there is no need to take them from Hongkong. If there is no domestic, it is not yet approved to enter the Chinese market, so that the hospital did not dare to use you, earn money, do not make money is a small matter, checked to the hospital and the doctor on the end.

So, you have to use it, it's more reliable to send the patient to Hongkong.
Q:In the fire fighting pipeline, how is the flange piece quantity calculated?
1, the fire pipe flange to vice as a unit, apply eighth copies of the corresponding items.2, flange (Flange), also known as flange or flange. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. There is a bolt hole on the flange which bolts the two flanges tightly together. Flanges are usually sealed with gaskets (flanges, gaskets).3, fire pipes, as the name suggests, is for the establishment of fire pipe system, due to special needs, fire pipes thickness and material have special requirements, and spray red paint, fire water transmission.
Q:What does "-150# SO/FF" mean by flange 4?
Size: 4"Pound level: 150#SO: flat with neckFF: flat surface (flange sealing surface)
Q:Mechanical flange problems,
This should be M12 thread depth, drilling depth of 24mm, tapping depth of 23mm.
Q:What is blind through flange?
The through flange is used to connect the two pipe fittings, and the two flanges are connected together by bolts. For the blind flange end of the pipeline, to shut off the pipeline
Q:CF, ICF, is the flange the same?
The screw holes shall be fixed by screws and nuts, and the flanges only need holes through which the screws pass. Screw type flange nut is not required, the flange screws fixed directly into. The flange material is mainly SUS304. SUS304 emits less gas and is easy to process and weld.
Q:Where is the identification shop in flange city (coordinate)?

Q:What are metric tubes and British tubes? What's the difference between them? How do you choose flanges?
It should be the metric tube and the British tube, that is to say, the B series and the A series.According to the flange diameter of the steel pipe, the flange diameter should be chosen according to the outer diameter of the steel pipe.The national standard flanges sold on the market are generally B series, and the A series shall be noted.My company website has flange standard, and corresponding steel pipe size. If necessary, please: Hebei, Mengcun Hao elbow elbow pipe manufacturers, station search,
Q:How to calculate the flange quote formula?
Well, I come with you to analyze the existing problems of the calculation formula, this formula is not actually a few written, there are certain to me now to analysis:The first formula is as long as the steel industry in the people to see that, this algorithm is certainly a problem, the problem in 0.616, 10 mm per metre weighs 0.616 kg, and (diameter * outer diameter - diameter - * * * aperture aperture hole number) * actual volume = flange thickness. The latter 0.00001 CM is the calculation of the results into g. such a calculation method, I temporarily ignore how he results, first of all, there is a theoretical error, ask the volume of *0.616= weight?The theory cost and actual operation cost cost, the general foreign trade company own calculated price bargain with us, so the price is called the theory of price, and we are holding the actual cost of operation between manufacturers, often makes us uncomfortable is the theory cost and actual cost gap.Let's analyze some of the most widely used formulas for calculating flange weight on the web:(outer diameter * outer diameter * inner diameter * bore bore diameter * hole diameter * hole number * thickness *0.616*0.0001 unit cmExternal diameter * outer diameter * inner diameter * bore bore diameter * bore bore * thickness *7.93*0.0001 unit cmOutside diameter * outside diameter *1234*, thickness inner diameter * inner diameter *1234*, thickness *0.00001
