Cathodic Protection Test Stations

We custom design, manufacture and install cathodic protection cp test stations, junction boxes, and anode bond boxes. We also survey oil and gas pipelines, and storage tanks to determine the best placement for test stations with remote monitoring. We are located in Midland, Texas, and service oil and gas pipeline companies globally.

Since 1991, we have manufactured and installed thousands of cathodic test stations, our corrosion technicians hold NACE, ISN Contractor and Master Evaluator Certifications to ensure quality, safety and reliability.

Custom Client Specifications

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

Safety, regulations, performance, installation, and cost are considerations that go into the test station design process. Cathodic test stations provide electrical contact with a buried pipeline for both cathodic protection and pipeline corrosion monitoring. Test stations are also designed for durably to last for years of service.

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 for Cathodic Protection

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.
