Blind Flange (BL)

BL (Blind) flanges according to ANSI/ASME standards (in particular ASME B16.5) are blind flanges, meaning they are used to close the end of a pipe, a fitting, or a valve.
They have no central bore and are used to block the flow of fluid.

Characteristics of the BL flange (Blind Flange):

• “BL” is the abbreviation for Blind, meaning blind flange;
• Used to close the end of a pipe, a valve, or an opening in a vessel;
• It has no central bore, therefore it does not allow fluid to pass;
• Easy installation and removal for maintenance;
• Ensures sealing even at high pressures;
• Can be modified to accommodate vent valves or instruments;
• Without a central bore, it can be drilled later for inspections or venting.
