Line Blinds: Spectacle Blinds, Paddle Blinds and Paddle Spacers
Sometimes events defy logic, and you just have to go with the flow.
We noticed recently that our video of a spectacle blind was hugely popular on our YouTube Video Channel.
It's a cool video, but apparently more interesting than even we realised. Sure Flow Equipment sells lots of these, so it never hurts to 'go with the flow' (which is appropriate in the strainer business) and do a review of this product line which includes spectacle blinds, paddle blinds and paddle spacers.
Spectacle Blinds
A spectacle blind is a simple safety device that installs between two pipe flanges. During normal operation the open end is installed as a spacer to allow uninterrupted flow. To stop the flow in the pipeline, the blind end is rotated into place between the flanges. This positively isolates the downstream piping and equipment.
Spectacle Blinds are generally installed as a permanent device. Having one end open and one end closed gives a quick visual indication to its orientation and whether or not it is safe to begin downstream work. If you can see the closed half, it means the half that is active in the pipeline is allowing fluids through. If the open side is visible it means fluids are not flowing through.
Paddle Blinds
A Paddle Blind is basically the solid half of a Spectacle Blind. A Paddle Blind is often made from one solid metal disc and will usually have a thin length of metal attached to one end to be used as a handle. A finished assembly will resemble the shape of a paddle, hence the name. Generally, these types of blinds are applied in piping systems that do not require constant maintenance. The Paddle Blind is used more as a temporary blocking device to stop flow in a process piping system.

Socket Weld Flange: A type of flange used for pipelineconnections, characterized by a socket at the end of theflange that can be welded to the end of another pipe. Thisflange is suitable for low-pressure and small-diameterpiping systems, with convenient connection and goodsealing performance.
High Neck Flange (or Long Neck Flange): A specially!designed flange with a longer neck and higher rise com-pared to standard flanges. This design increases thestrength and rigidity of the flange, making it suitable forhigh-pressure and high-temperature piping systems. Thehigh neck flange is typically used in applications that re-quire resistance to high stress and thermal expansion.
Threaded Flange: A type of flange for pipeline connec-tions using threaded connections. lt features internal andexternal threads on the hub that allow connection to pipeswith corresponding threads.Threaded flanges are suitablefor low-pressure and small-diameter piping systems, offer.ing easy installation and disassembly.
Large Diameter Flange: The Large Diameter Flange istypically used in connecting large-scale piping systemsCharacterized by its large diameter, it can accommodatehigh fluid flow rates and elevated pressures. This flange isgenerally connected by butt welding or bolted flanges, en-suring robust and leak-tight connections.
Slip-on Flange: The Slip-on Flange is a type of flange thatoffers convenient installation. lts hub does not requirewelding but is securely bolted to the pipe, allowing foreasy installation and disassembly. The Slip-on Flange issuitable for piping systems that require frequent disassem-bly or maintenance.
Orifice Flange: The Orifice Flange is a special type offlange that incorporates an orifice plate for measuring fluidflow rates and pressures. The hub of the orifice flange typically features internal threads or flange connections for at.tachment to corresponding piping. lt finds widespread application in flow metering and control systems.
