The Right 3Skeng Library

Looking for an Engineer (or any individual) that is familiar with 3Skeng. I’m currently working on a drawing and the material request asks for Sch 10, 511B Class Piping. I’m not finding that material in any of the 3Skeng Libraries I currently have. Noir am I seeing that particular pipe option in the 3Skeng Extension Library. I’m wanting to make sure I’m using the correct material with the detail option in 3Skeng so that when I make the material list/labels all is well. Anyone that can help?
