Spectacle Blind flange is a special type of pipeline connector, with a shape similar to the number "8", composed of a solid blind flange and a hollow circle (throttling ring end), connected by a flat connector in the middle; It can be applied to pipeline systems with different diameters, and its nominal pressure range is usually 0.25Mpa-42.0Mpa, including multiple pressure levels.
Common seals include FF and RF
Material: Carbon steel has good strength and corrosion resistance, suitable for general industrial pipeline systems, such as normal temperature, medium and low pressure pipelines in the fields of chemical, petroleum, natural gas, etc.
Stainless steel has excellent corrosion resistance and high temperature resistance, making it suitable for pipelines that transport corrosive media or work in high-temperature environments.
Application scenarios:
Petrochemical industry: used to connect joints between different pipelines
Sewage treatment industry: widely used to connect various components in sewage treatment systems, such as pump rooms, filters, and sedimentation tanks, to ensure that sewage does not leak during the treatment process and to ensure the normal operation of the sewage treatment system.
Construction industry: used to connect water pipes and heating pipes, which can effectively prevent freezing, cracking, and leakage of water pipes and heating pipes in winter, reducing unnecessary losses.
