Changes regarding the design of the semi-circular pipe jacket in 20582-2020
Thread Content
Regarding the design of semi-circular tube jackets per HG/T20582, the 2011 version states that \"this chapter applies to the design of circular, spherical, butterfly, or elliptical end caps equipped with semi-circular tube jackets\"； The half-circular tube jacket is at positive pressure. The 2020 version states that \"this chapter applies to the calculation of the strength of semi-circular tubes with jackets, where the shell or head is subjected to internal pressure and the jacket itself is also a semi-circular tube under internal pressure, etc.\" The difference between the two can be understood as whether the condition of a negative design pressure for the inner cylinder in 20582-2020 is not applicable? I look forward to your replies
The answers given by everyone on this matter are not authoritative either. It is recommended to contact the relevant authorities. This should be handled with the **State Administration for Market Regulation**.
