Q:Who knows, the difference between plate flange and hubbed flange in the application.

Hubbed flange is imported from abroad, used for gas valves, gas pipelines etc.. Because of a short neck, flange stiffness can be improved and bearing capacity improved.

Q:Introduction of flange

Flanges (Flange), also called flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures.

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 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:Flange WN50 (B) -25 RF S=6 specific points

WN indicates that butt welding 50 means nominal diameter DN (B means B series diameter is 57) - 25 is pressure, new standard is 25 kg pressure, old standard is 250 kg pressure RF, sealing surface protrusion S=6 flange diameter thickness is pipe thickness

Q:For flange who is more detailed explanation? For example, how to position?

The question is a bit difficult to answer. I use some commonly used criteria to explain it.The ASME B 16.5 -2009 defines the construction criteria for pipe flanges and flanged fittings, including the definition of the flange pressure grade, the temperature and pressure curve of the flange material, etc., and is a very detailed construction code. According to the two part of the flange, a flange sealing surface in the form, such as the process of the convex surface surface groove face ring joint face; two flange form, such as welding welding socket welding etc.!The definitions in EN ASME are similar to those in 1092-01-2007!. The difference is that the ASME defines a pressure rating of CLASS series EN, defined as the PN series, and differs in the size of the flange sealing surface and the flange form.HG/T 20592-2009, the latest 2009 edition of the Ministry of chemical flange standards on the basis of the largest reference to the definition of ASME and EN, but there are still differences. In EN 1092-01-2007, at the same level under different pressure, the thickness of the flange form may not be the same, but in HG/T we can clearly see that all the size of the flange flange form is used in EN integral flange thickness. Personal feeling of the Ministry of chemical engineering flange standard strict and logical, and EN and ASME still have a gap.

Q:What are single plate flanges, short tubes, flanges, short tubes, flanges, three connections, and flanged bends? What is the material? What is it?

Flange GB9119 GB9116 HG20592 elbow GB12459 three pass GB12459

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:Works 2012 boundary flange profile editor cannot drag boundary line. Seek expert advice ah! With 10 of the time, you can directly modify the contour, the result of a change of 12, you can only input data, and then only size, very troublesome. I don't know where to change it. Seek advice. Thank you

My 12 is ok! Is there a geometric constraint? First remove the geometry constraint, then drag it out and finish that one at the last point

Q:To be made?

Yes, Guangzhou Huanya group, is a company with skin care
