ASME Flange Fastener Standards
Thread Content
In ASME B16.5-2009, it is possible to find out which specification of fastening bolts should be used for a given flange based on its type, diameter, and pressure class. But in which standard should one look up the specifications for the nuts that go with these bolts? There is a interstage cooler at the site, manufactured by Jiangnan Boilers for Drayson reciprocating compressors. The inlet and outlet flanges on the tube side are designed and fabricated in accordance with the ASME B16.5-2009 standard. I currently only know the specifications of the flanges; I would like to determine the specifications of the bolts and nuts used to fasten them by referring to relevant standards. I would appreciate guidance from those with experience in heat exchanger design. Thank you!
Look for it slowly inside 16.5. . . There is a recommended table for bolts, Table 1C
I’m not sure what to ask. From the flange data sheet in the standards, one can find the bolt specifications, such as 1/2\", so wouldn’t the nut also be 1/2\"?
Search for PIPEDATE on the forum; none of what you’re saying is a problem
In which standard should one look up the specifications for the nuts that come with bolts? If your bolt is, for example, 1 inch in size, then the nut that corresponds to it is also 1 inch in size.
Yes, the bolt is one inch in length, and the thread diameter of the nut is also one inch. But what about the distance between the opposite sides of the hex nut? How is this determined?
The standards for checking nuts: for 1-inch American standard heavy-duty nuts, the maximum distance between opposite sides is 41.27, the maximum diagonal distance is 47.65, and the thickness is 25.7
The specifications of a nut aren’t just the diameter of its threads; a 1/2\" bolt is matched with a 1/2\" nut. What I want to know is that the thickness of a 1/2\" nut, as well as dimensions such as the distance between its opposite sides, can be found in what standards
Hmm, what is this standard number you mentioned? {:3_65:}
For flange standards, isn’t it required that the nuts comply with ASME B18.2.2? They are usually heavy-duty nuts.
I took another close look at B16.5 and I can see it now, thank you!
