Q: How do you calculate the size of the flange? How many inches do you calculate? What's the inside diameter or what?: Flange outer diameter 190, inner diameter 80 is 3 inches.The correct parameter is the outer diameter 195mm, the inner diameter 89mm is the DN80 flange piece

Q: What's the difference between RF flange and RJ flange?: The difference between the RF flange and the RJ flange is that the seal is different.RF flanges are flat sealsRJ flange is steel ring seal

Q: there is a pair of flange drawings, the above mark is 6-M12 evenly distributed 23 drill 24, what is the specific meaning?: If the bolts have been purchased, they will be drilled 27, and if the size of the workpiece is not enough, it must be changed to attack 21.However, since the M12 thread usually has a thread length of 10 to 12, the lengthened length is 15 to 16, and 16 is the thread matching surface. Plus 2mm margin, can be designated as tapping 18, drilling 22., so that processing operators more relaxed.As a result of the distribution of force per thread teeth suffered extremely uneven, some teeth burden some teeth almost no stress, length too long, is not obvious to improve the strength of thread, but on the processing and assembling to increase a lot of trouble, so, if it is not a special case, do not add the length of thread. Therefore, the ideal is to attack 12 drill 16 (put 2mm installation allowance), if the strength is not enough, to see whether the installation position can be changed to M14, according to the specific circumstances.

Q: What does the Rc-RF in the flange stand for? What do they stand for?: Rc is the threaded flange,The internal teeth are 55 degrees of degree of PT teeth, the standard of the teeth, the Japanese standard is JIS B0203, the European standard is ISO, the 7-1 German standard is DIN 2999,RF, as mentioned upstairs, means that the sealing surface is bulging

Q: What role does Sino French play in the waterproof casing pipe?: Such as ventilation pipeline connection, the parts can be called "flange parts." but this is only a partial connection of a device, such as a connecting flange and a water pump, the pump is not called "flange type parts" relatively small. Such as valves, etc., can be called flange parts

Q: What is the SO flange?: Hubbed flange. The other can query HG20592-2009, there are inside.

Q: Now in chemical, flange pn2.: Nominal pressure PN (=2.5MPa):Reference value relating to the pressure resistance of piping system componentsWorking pressure is the maximum continuous running pressure acting on the inner wall of a pipe under normal working conditions.

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: 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.
