Today my boss asked me to take 100 of the flange, I will according to the outer diameter and center distance large size flange, the boss said, after see, let me see see me outside diameter, what not, where do you refer to the flange diameter? Pipe? But I found some flanges were not the same size, but they were as big as pipes
First you answer the questions below hubbed flange and flange plate flang is not the same type, hubbed flange type code is SO, and the plate flang can be PL, or SO, the difference in sudden surface (RF), is a type of convexity the sealing flange, flange type and don't confuse. Then explain what you mean by the nominal size and the outer diameter of the pipe. Nominal size refers to the menstrual flow, because the pipe thickness, so in general the tube size will be a bit bigger than the nominal size. Flange fittings of the object, so the flange of the specific size should be determined by pipe fittings.
Read more standard books, see more and more, and see more of them.The second question, caliber size is the same.
Flange specifications generally refers to the customs. Flanges are standard. No, generally large. Different, one with neck, one without. But the neck is convex. Caliber size is the same, read more standard books, more volume, more look, see more naturally understand.Flange size is determined as follows:1, first determine the flange type, flange type commonly used with flange, flange, butt welding socket welding flange, flange plate, loose flange ring;2, and then determine the flange end of the form, mainly RF, concave, convex, RJ torus. Tongue and groove face;3, after determining the flange type, the main measurement data include bolt hole center distance, flange diameter, flange thickness, flange joint pipe bore and so on;4, and then the measured data and standards relative to, you can see the specific type of flange.5, reference standards HG20592 and HG20615, you can query the size of the flange.Flanges, 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.
