NEW Kleerband Flange Protectors are the quick, easy and effective way to apply protection and prevent corrosion. Why try and protect flanges the old way when APS has the new, clear advantage to prevent corrosion? Kleerband Flange Protectors are manufactured of 100% virgin vinyl compound, which allows visual inspection of the flange surface without removing the flange protector.

Flanges, the most common trouble area, need to be sealed properly to prevent leakage and must also be cathodically insulated to prevent stray currents which cause undue corrosion and eventual breakdown of the metal. Advance Products & Systems manufactures and maintains a supply of quality products and materials which help solve most flange sealing problems, therefore preventing subsequent corrosion and saving the integrity of the pipeline.

Advance Flange Protectors are designed to protect studs and gaskets on raised face and ring type joint flanges from atmospheric corrosion encountered in chemical plants, refineries, gas plants, offshore platforms, onshore oil fields, ships, paper mills and underground pipelines. Stainless steel or plastic models are available, in all sizes, for preventing corrosion between flanges on piping systems.

Advance Flange Protectors and corrosion inhibitor grease are recommended on all insulated flanges. By encapsulating the flange cavity with the flange protector and injecting our corrosion inhibitor grease, you can rely on your cathodic protection system to provide you with years of trouble free service.

This system totally eliminates any possibility of foreign matter lodging between the faces of your flange or corrosion bridging across and creating a short. Advance Flange Protectors are manufactured of 22 gauge 304 or 316 stainless steel band, stainless steel worm-gear strap, and grease fitting. An exclusive positive loading relief vent and plug that assures complete loading of flange cavities, plus allows you to visually inspect the flange without removal of the protector, is standard. The gasket is made of 18mm closed cell neoprene for positive seal. (Other gasket material available upon request.)

Advance Flange Protectors are manufactured according to ANSI B16.5 specifications up to 600mm. Above 600mm, please provide the specifications of your flange including the circumference. Technical assistance is available upon request.

Flange Protection Corrosion Test
Flange assembly #1 was plain and unprotected. Flange #2 was protected with a Kleerband® Flange Protector and Radolid® Nut Caps. Testing consisted of 500 hours ASTM B 117 salt fog exposure.
(Actual test result documents available upon request)
At the start of the test
500 Hours later
End result: Flange, nuts and bolts badly corroded making flange seal failure possible. Maintenance difficult at best.
End result: Flange, nuts and bolts in good repair with seal integrity safe for years. Maintenance can be achieved with efficiency.
Kleerband® Flange Protectors prevent this type of damage from occurring.
