Cathodic Test Station Design & Manufacturing

Since 1991, designing, manufacturing and installing cathodic protection test stations, junction boxes and bond boxes. Surveys are also offered for oil and gas pipelines and storage tanks to determine the best locations for the test stations. We are located in Midland, Texas, and serve the entire Permian Basin.

We have manufactured and installed thousands of cathodic test stations and our technicians hold NACE, ISN and Master Evaluator Certifications to ensure quality, safety and reliability.


Custom Specifications

Test stations are essential to the cathodic protection program and used to monitor operational parameters and overall effectiveness. Custom specifications include 1 1/4″ or 3″ PVC versus steel U Post, #10 or #12 solid versus stranded wiring, 3/4″ steel head, 3/4″ rigged conduit and back plate.

Safety, regulations, performance, installation effort and cost are all considerations in the test station design process. Cathodic test stations provide electrical contact with a buried pipeline for corrosion protection and remote corrosion monitoring. Test stations are also designed for durably and last for years of service.


All cathodic test stations are manufactured using non-corrosive, non-conductive, light weight and durable materials to protect from corrosion, and back scratching cattle.

The two wire test station is the most frequently used, two wires make it possible to check pipe-to-soil potential voltages as a D/C current is applied to the pipeline. The test stations should be located where they will be convenient and practical for the corrosion personal to access. Space is left above the test station head on the mounting up-post to allow for company pipeline warning signs.

Test stations measure the potential between the pipeline and electrode using voltage readings from remote monitoring, less negative potential indicates higher levels of cathodic protection. Measurements are taken at every road crossing, pipeline crossing, and every mile of pipeline plotted for a highly accurate scientific corrosion assessment.

We also maintain and service all test stations including new box covers, retention screws, cover gaskets, terminal nuts and screws.


Anode Junction Boxes

We design our junction boxes to survive the elements using .001Ω type SS or other various of shunts stainless steel enclosure, galvanize enclosures or no metallic enclosures, insulated panels, copper bus bar, 0.01Ω JB shunts, V50MV SW shunts, resistors or rheostats or adjustable resistors, meters and switches, blocking diodes and copper terminal lugs for assembly. Junction box mounting options include pole mount channel, wall mount tabs, or using custom client junction box mounting specifications.
