Does anyone who knows the sea know? I don’t know how to quote this.

SO means forceful butt welding; FF refers to full-plane welding; no hub seems to indicate the absence of a hub adapter. I’m not entirely sure about the details, so let’s wait for an explanation

SO stands for Slip on, with a flat welded flange. It refers to a method of connecting pipes to flanges. FF stands for Flat face or Full face, meaning completely flat. It belongs to the flange seal surface type.
