Cathodic Protection Warning Tape
OPALUS PACK is a manufacturer of cathodic protection warning tape for underground corrosion protection projects where buried CP cables, CP lines, sacrificial anode cables, and ICCP circuits need clear identification before future excavation. Made from durable polyethylene film, the tape is installed above protected cable routes to warn contractors before digging reaches the cathodic protection system. Detectable and non-detectable options are available for pipeline, tank, and buried metallic structure protection projects.
- Material: LLDPE or polyethylene film for direct burial identification
- Common Widths: 75 mm, 100 mm, 150 mm, or project-specified sizes
- Thickness Options: 50 um – 150 um
- Roll Length: 100 m – 365 m per roll
- Color: Yellow, red, or specified utility marking color
- Printing: Custom legends such as CAUTION CATHODIC PROTECTION CABLE BELOW
Product Overview
Cathodic protection warning tape is designed for corrosion protection systems, not ordinary power cable marking. In pipeline protection work, CP cable routes may connect sacrificial anodes, test stations, rectifiers, groundbeds, or monitoring points. If these lines are cut during later excavation, the corrosion protection circuit may be interrupted.
OPALUS PACK produces cathodic protection cable warning tape with clear printed legends and flexible project specifications. The tape is usually placed above the buried CP cable or CP line during backfilling, giving maintenance teams an early visual warning before they reach the cable level. This helps separate corrosion protection wiring from general underground utilities.
For projects based on accurate drawings and simple visual warning, non-detectable polyethylene tape is often enough. For long pipeline corridors, congested underground areas, or sites that may need future route tracing, detectable cathodic protection tape with a metallic tracer layer can provide an additional locating reference.
Benefits
- Helps identify buried cathodic protection cable routes before excavation reaches the cable.
- Supports pipeline corrosion protection warning tape requirements in oil, gas, water, and industrial infrastructure projects.
- Reduces accidental damage risk to sacrificial anode cables, ICCP circuits, and test station connections.
- Permanent printed legends keep CP cable routes easier to recognize during future maintenance.
- Width and thickness options help match trench conditions, burial depth, and project marking standards.
- Detectable versions support underground route confirmation where locating equipment will be used.
What Is Cathodic Protection Warning Tape Used For?
Cathodic protection warning tape is used to mark buried corrosion protection circuits. It does not provide corrosion protection by itself. Its value is in identifying CP cable routes, cathodic protection line paths, and related underground connections before the actual cable is exposed. This is useful around buried steel pipelines, storage tanks, terminal facilities, and metallic structures where repair or expansion work may occur years after installation.

Applications
- Buried pipeline cathodic protection systems where CP cable routes require clear identification.
- Sacrificial anode cable routes and connection points around buried metallic structures.
- Pipeline test station cable identification for inspection and maintenance access areas.
- Underground storage tank corrosion protection projects where cable marking must remain visible during future excavation.
- Oil, gas, water, and industrial pipeline corridors where CP system wiring runs near other buried services.
- Maintenance zones where underground CP cable marking tape is preferred for route tracing.
When Should Detectable Cathodic Protection Warning Tape Be Selected?
Detectable cathodic protection tape is commonly selected when the project may require future excavation, route verification, or maintenance along the protected line. The metallic tracer layer gives an extra locating reference when used with suitable detection equipment. This is useful for long-distance pipelines, busy utility corridors, or older sites where drawings may not be enough. Non-detectable tape remains practical when visual warning above the buried cable route is sufficient.
FAQ
Is cathodic protection warning tape the same as electrical cable warning tape?
No. Electrical cable warning tape is used for power cable identification, while cathodic protection warning tape is made for CP cables, CP lines, sacrificial anode connections, and corrosion protection circuits.
Can the warning legend be changed for a project?
Yes. OPALUS PACK can produce custom warning legends, including cathodic protection cable, cathodic protection line, CP cable buried below, or project-specific text required by drawings.
Should I choose detectable or non-detectable tape?
Choose detectable tape when future underground locating is required. Choose non-detectable tape when visual warning is enough and accurate site records are available.
What specifications are commonly used for CP warning tape?
Common options include 75 mm, 100 mm, and 150 mm widths, 50 um – 150 um thickness, and 100 m – 365 m roll lengths. Final specifications should follow project requirements, burial conditions, and marking standards.
