Product Description

Blind flange is a special type of flange in pipeline systems, mainly used for isolating, sealing or terminating pipeline flow paths.
Basic Structure and Characteristics
1. No central hole: Unlike ordinary flanges, blind flange is a solid disk without a through-hole in the middle, used to completely block the flow of medium.
2. Flange surface design: There are bolt holes at the edges, which can be fastened with matching flanges by bolts to form a seal.
3. Diverse materials: Depending on the working conditions, materials such as carbon steel and stainless steel can be selected.
4. Pressure rating: JIS B2238 5K 10K 16K 20K 30K 40K 63K
Main purpose
1. System isolation: Temporarily block pipelines during maintenance to ensure safety.
2. Pipeline end sealing: Reserve interfaces for future expansion.
3. Pressure testing: used as a sealing component during pressure testing.
4. Prevent backflow or leakage: Long term closure of unused branch pipes.
