Flange Band Protectors are designed to protect flange internal areas including the flange faces, stud bolts, and gaskets, from environmental elements that can cause corrosion.

Flange protectors by Drake Specialties are used in the oil and gas industry, refining, gas distribution systems, and any place where it is necessary and desirable to protect flanges and joints from salt spray, chemicals, sand, debris, and other rust causing external factors.

Flange ProtectionFor a complete flange protection system, we recommend including Drake Specialties Nut/Bolt Protector Caps and Corrosion Inhibitor Grease. The Nut/Bolt Protector Caps are plastic caps that snap tightly over nuts to protect stud ends and nuts from corrosion. The caps allow for easy unbolting of flanges and valves.

NOTE: Flange Protectors do NOT prevent lateral spray-outs, and therefore should not be used as safety devices. Flange Spray Shields are designed for spray protection and containment. 

While nut caps may be used to eliminate excessive paint buildup on bolt threads, the leading benefit is defending the stud bolt threads and hex nuts from rust and corrosion, thus allowing easy unbolting. Nut Caps are economical, reusable, easily installed, and available in all sizes for heavy hex nuts ranging from 1/2″ to 3″.

For additional corrosion protection, we recommend our flange and nut protection grease – Corrosion Inhibitor Grease – added inside the caps to displace air and moisture and extend service life. Grease is available in 14oz cartridges/tubes and 5 gallon pails.
