In the standards for steel butt-welded seamless pipe fittings GB/T 12459-2005 and GB/T 13401-2005, what does the intermediate pressure grade LG mean?

Could the poster explain the location of LG? I took a quick look but couldn’t see its source.

Where is LG? This LG is not included in the general standards; I’ve never seen it before either

The pressure ratings commonly used abroad refer to pound ratings!

Could the person upstairs please explain in detail where it can be found?

It might be the pipe grade; L indicates a pressure rating of 1.0 MPa, while G indicates that the pipe material is non-metallic
