What does a flanged sleeve look like? I’d like to ask
Thread Content
As the title suggests, it’s about welding a pipe using flanges. What about the welding length? The relevant parameter is given as HG/T 20592 20-16 RF, with A=M20x1.5. Could you provide me with a diagram?
If it’s a thermometer, then the length of the sleeve should be equal to the insertion depth of your thermometer.
I’ve really never seen such a way of representing it; it must be something you created yourself.
It must be like this; the thermometer itself has a 20-threaded connection
HG/T 20592 20-16 RF: A=M20*1.5. The 20-16 refers to a flange with a nominal diameter of DN20; the nominal pressure is 16 kilograms, which is equivalent to 1.6 MPa. RF indicates that the sealing surface is of the raised type, while A=M20X1.5 specifies the specifications of the bolts used with this flange.
Oh, it’s probably due to the temperature; there are components that are affected by temperature. Thank you all
I’ve never seen it; it seems to be some kind of non-standard item.
