I’ve really never heard of a minimum thickness requirement; you can check standards such as HG20553 and SH3405

You can take a look at HG/T20615; it specifies the wall thickness of the fittings. I’m not sure about the minimum wall thickness though

SH/T 3059-2012 Standard for Selection of Materials for Pipeline Design in Petrochemical Industries, 7.1.4. For reference

The latest regulations require that the minimum wall thickness be greater than or equal to the design wall thickness.
