Underground Corrosion Control

C.P. Test manufactures non corrosive curb, valve, and drip boxes, has serviced the public utilities for 32 years. Our line of corrosion protection test stations has pioneered this field, manufacturing both standard test and custom test stations to meet specific requirements.

Many millions of dollars are spent annually by gas, electric, telephone and water utilities to protect underground metallic structures against corrosion. The C.P. Test Box is the hub of the entire cathodic protected system.

Cathodic protection, in effect, is only as good as the Test Box. You will find that C.P.’s test stations will meet the most stringent standards. They are time tested by some of the largest utilities in the United States.

Since cathodic protection is so essential today to maintain old installations, protect new ones against future corrosion, and, in particular, protect additions of new pipe lines to old, it follows that protection and accessibility are key features of the program. C.P. installations will provide these essentials as well as extra dependable features to insure long life. This is the pivotal part of the corrosion protection system.
