BL RF Blind Flange for Standard Pipeline Systems

BL RF Blind Flange for Standard Pipeline Systems Product Overview The BL RF Blind Flange is a solid, disc-shaped Standard pipeline flanges designed to seal the end of a pipeline or close off an unused flange connection, serving as a critical industrial pipeline connection flanges for isolating sections of piping systems during maintenance, testing, or permanent closure. As a key member of multi-standard pipe flanges family, this blind flange features a raised face (RF) sealing surface that mates with other flanged components, ensuring a leak-proof seal in low-to-ultra-high pressure systems (Class 150-2500). Unlike other Standard pipeline flanges (WN/SO) that connect pipes, the BL RF Blind Flange has no bore and is bolted directly to a mating flange (WN/SO/PL) to seal the pipeline end. As a standardized component in multi-standard pipe flanges range, it complies with ASME B16.5, EN 1092-1, and GB/T 9119 standards, ensuring compatibility with global piping systems and making it a versat…
