Corrosion & Harsh Environment Protection
Pulp and paper processing involves corrosive agents
that cause fast and irreversible deterioration, such as
hydrogen peroxide, chlorine or other chemicals used
for bleaching pulp, as well as harsh cleaning chemicals,
abrasive raw materials, moisture, heat and humidity.
According to a study commissioned by the U.S. Federal
Highway Administration, corrosion costs the U.S. pulp
and paper industry an estimated $6 billion annually.*
Production problems caused by corrosion include:
• Equipment failure and shortened life
• Poor electrical system reliability caused by high-
resistance connections
• Long maintenance repair time due to corroded parts
• Safety hazards
The use of corrosion-resistant materials is critical
to extending the life and reliability of your electrical
system. Thomas & Betts offers electrical system
components in aluminum, stainless steel, specialty
alloys, non-metallic and PVC-coated materials as a
solution to your corrosion issues. Please refer to page
20 for more information on the resistance of these
and other materials to various chemicals.
PVC-Coated Conduit Bodies
• Cast-iron bodies and covers coated inside and out with
2 mils blue urethane, then exterior coated with 40 mils
PVC for double-coated corrosion protection
• Ship with covers and encapsulated stainless steel screws

Heavy-Duty Coated Stainless Steel Cable Ties
• Marine-grade Type 316 stainless steel, fully coated
with low-smoke, halogen-free polyester for use in
temperatures from -40° to 150° C
• Quick, easy installation and secure locking
Conduit Bodies
• Triple-layer corrosion protection — including two layers
of epoxy coating — stops corrosion in its tracks
• BlueKote
internal surface coating reduces force
required to pull wires and offers extra corrosion protection
Aluminum Conduit Boxes
• Made from special copper-free aluminum alloy to resist
corrosion far better than standard copper-free aluminum
• Designed and tested to withstand prolonged exposure
to corrosive agents and extreme temperatures
Stainless Steel Liquidtight Conduit Fittings
• Type 304 stainless steel construction provides strength,
durability and corrosion resistance
• Straight, 45° and 90° angled — UL
Listed Type 3, 3R, 4,
4X for connecting flexible metal conduit to an enclosure
