JIS 5K & JIS 10K Blind Flanges
JIS 5K and JIS 10K Blind Flanges are pipe flanges manufactured according to JIS B2220 standards and used to close the end of pipelines, valves, or pressure vessels. A blind flange is a solid flange without a center bore, designed to completely stop the flow of fluids or gases in a piping system.
JIS blind flanges are widely used in oil and gas pipelines, petrochemical plants, water treatment systems, shipbuilding, and industrial piping networks where pipeline isolation and secure sealing are required.
Because blind flanges are bolted rather than welded, they can be easily removed for inspection, maintenance, or pipeline modification.
JIS B2220 Blind Flange Standard
JIS B2220 is the Japanese Industrial Standard that specifies the dimensions and pressure ratings for steel pipe flanges.
Common pressure classes include:
-
JIS 5K Blind Flange
-
JIS 10K Blind Flange
-
JIS 16K Blind Flange
-
JIS 20K Blind Flange
Among them, JIS 5K and JIS 10K blind flanges are the most commonly used for low and medium pressure piping systems.
Applications of JIS Blind Flanges
JIS 5K and 10K blind flanges are widely used in various industries including:
Water Treatment Systems
Used for sealing pipe ends and isolating sections of pipelines.
Oil and Gas Industry
