Flange Band Protectors


Flanges, the most common trouble area, need to be sealed properly to prevent leakage and must also be cathodically isolated to prevent stray currents which cause undo 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.

Corrosion costs more than just money

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.

This system totally eliminates any possibility of foreign matter lodging between the faces of your flange or corrosion bridging across and creating a short.

Stainless steel or plastic models are available in all sizes for preventing corrosion between flanges on piping systems. Advance Flange Protectors are manufactured according to ANSI B16.5 specifications up to 24″. Above 24″, please provide the specifications of your flange including the circumference. Technical assistance is available upon request.

ISO 9001 Quality Certificate


NEW Kleerband® Flange Protectors are the quick, easy and effective way to apply protection and prevent corrosion. Why protect flanges the old way when Comdiflex Advance 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.

Stainless Steel

For high temperature applications

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 assures the 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 3/16″ closed cell neoprene for positive seal.

Kleerband® Flange Protectors and Kleergel® corrosion inhibitor grease are recommended on all isolated 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.
