Kleerband Flange Protectors, recently introduced by Allison Engineering, provide a quick and easy way to apply protection and prevent corrosion.

They are simple to install with a worm-gear connection, with no mess or special tools.  They feature a positive loading relief valve vent and plug which ensures complete loading of flange cavities, while a transparent and flexible polyband allows for 360º uninterrupted inspection, without the need to remove the protector.

Kleerband protectors are designed to fit all DIN and ANSI flanges from ½in diameter up to 144in and are available for non-standard sizes and Christmas-Tree applications off-shore. In addition to being used on oil and gas installations they are suitable for protecting flange faces, studs, gaskets and ring joints on pipelines in chemical plants, refineries, oil fields, metering stations, water and waste water plants, pump stations and underground pipelines.
