Test everyone 16: Quality calculation problem of integral flange IF in HG/T20592
Thread Content
bg4.png Test everyone 16: Questions about the mass calculation of the integral flange in HG/T20592 1. Can the joint be laid out according to WN+. 2. If it can be laid out, what is the value of the wall thickness of the nozzle? 3. There should be a limit to the total height, otherwise it would be uneconomical, so what is the appropriate height? 4. What do you think about it? Overall flange quality https://bbs.hcbbs.com/thread-1280766-1-1.html
This post was last edited by wanlirn on 2019-7-14 13:03 The original poster raised such a question, which is problematic in itself. Some people use flanges to mix the integral flange and the necked flange (the appearance is somewhat similar). First of all, the necked flange in GB150 is an integral flange and it is not the integral flange in HG20592. The integral flange and the stiffened flange in HG20592 both belong to the integral flange in GB150. ； It’s a bit convoluted! @@The integral flange in HG20592 is used on the interface of the valve and pump to match the pipe flange. Your so-called integral flange and the pump are cast as a whole. In this case, does the weight of a single integral flange make sense? Some people also say that my pump shell and flange are welded, so you can use other flat-welded flanges with necks. That is to say, unless you are designing cast and forged valves and pumps, you will not use integral flanges.
Is this picture missing the length dimension?
This problem has always troubled me. What is the difference in use between WN neck butt welding flange and IF integral flange? They all look the same.
If the integral flange has a length, it is not called an integral flange. The total height of the integral flange is set out according to the protrusion of the pipe mouth, and then customized. Because the height is generally higher, the cost will be three or four times.
It is generally used when the medium is special, high pressure, and low temperature. To put it bluntly, it means that no trace leakage is allowed.
That means when calculating the weight, just take the actual length, right?
As for the wall thickness, press So above?
I hope someone can give a reasonable answer
