High hub blind flange is a type of flange used in pipeline systems to completely seal the ends of pipelines. It does not have a central hole and is mainly used for isolating, sealing, or temporarily sealing pipeline systems. A blind flange is a circular or square metal piece with a flange surface on one side that matches the outer and inner diameters of the corresponding pipeline size, and has several bolt holes, and a smooth sealing surface on the other side. When installed on the pipeline, it is fixed to adjacent flanges with bolts and nuts, forming a completely closed fracture.
Characteristics of high hub blind flange:
1.Good sealing to prevent medium leakage
2.Rust and corrosion prevention, sturdy and wear-resistant
3.Good disassembly capability
4.Widely applicable, suitable for various occasions
5.Flexible selection
