Thread Content

I would like to ask everyone: what is the standard regarding the exposure of the threaded bolts on the pipe valves and flanges at high-pressure natural gas stations? Which specific standard requirements should be followed during installation and acceptance? Thank you!

The flange standards specify the requirements for bolt and stud sizes! It’s best to follow the standards!

After tightening, the exposed length of the bolt should be 2 pitch lengths
