Does GBT 14383-2008 require the wall thickness of the spool in forged socket-welded and threaded pipe fittings to start at SCH80? Why? ? Besides the GBT 14383-2008 standard, are there any other standards that can be followed for socket weld and threaded pipe fittings? The key point is that the wall thickness requirement doesn’t need to be that high; are there standards for lower-grade socket-welded and threaded fittings? ?
The tube has become thinner, making it easy to weld through it during socket welding; moreover, as threading is performed the wall thickness decreases, so it can no longer bear pressure, right?
Then, since GBT 14383 specifies only the wall thickness requirements in imperial units, and for domestic Series 2 it only provides requirements for the outer diameter, how should the wall thickness of this series be determined? ? Thank you!
There should be uniform standards for welding; relevant manuals can be consulted
For low-pressure applications, cast components can be used directly. Since 14383 refers to forged high-pressure fittings, its pressure rating and wall thickness are relatively high from the start
Excuse me, sir: are there any standards for low-pressure socket or threaded pipe fittings? ?
GB/T14383-2008, SH/T3410-2012, ASME B16.11, etc., are all
