Carbon steel flanges are designed to have standard dimensions. Common world standards include ASA/ANSI/ASME (USA), PN/DIN (European), BS10 (British/Australian), 

and JIS/KS (Japanese/Korean).

Carbon steel flange faces are also made to standardized dimensions and are typically [flat face", [raised face", [tongue and groove", or [ring joint" styles, although other obscure styles are possible.

Carbon steel flange designs: Weld neck flange (WN flange), slip-on flange(SO flange), lap joint flange(LJ flange), socket weld flange(SW flange), threaded flange(TH flange), blind flange(BL flange).
