Blind Pipe Flange is used whenever a line must be capped of at a flange. It is good practice to install blind pipe flange at the end od header or at location where future tie-ins are anticipated.
Blind pipe flanges are also used extensively for manways, in which case a davit is recommended for ease in handling the unbolted manway cover.
Blind pipe flange is specified by ANSI B16.47.
