Buried pipelines, storage tanks, ship hulls, offshore platforms and reinforced concrete corrode continuously in soil, seawater, groundwater and chloride-laden air. CP is the electrochemical method that stops this: an external current forces the steel surface into a protected potential so corrosion no longer proceeds.
Two systems exist: sacrificial anodes (zinc, aluminium, magnesium) that protect small or local zones, and impressed-current (ICCP) systems where a rectifier drives current through long-life MMO titanium anodes — the right choice for large, remote or decades-long assets.
Every CP asset faces a different environment. Match the threat below with the anode system Ehisen supplies for it.
Soil corrosion, coating defects, stray current and long-distance attenuation attack pipelines and terminals, especially where coatings are damaged.
Seawater, chloride exposure, splash-zone attack and difficult access accelerate corrosion on hulls, jetties, pilings and platforms.
Tank bottoms and vessel interiors corrode from soil contact, stored water and condensate — often inaccessible once in service.
Chloride ingress drives rebar corrosion in bridges, decks and tunnels, causing spalling that is expensive and dangerous to repair.
Different assets require different protection strategies. Use the guide below to match your application with the most suitable Ehisen solution.

ICCP is a system, not a single product. Every component below works together to hold your structure at a protected potential — and Ehisen supplies the anode and cable core of it.
Converts AC mains to DC and drives current through the anode circuit. Constant-potential or constant-current control maintains the target protection level automatically.
The current-discharging element — tubular, disc, strip, wire or mesh format with Ir-Ta / Ru-Ir / Ti-Al coatings rated to your environment and design life.
Cu/CuSO₄ or Ag/AgCl cells measure the structure-to-electrolyte potential so the rectifier knows how much current to deliver.
Dedicated YJV or PVDF/HMWPE-insulated cables and junction boxes distribute current to each anode and return to the rectifier with low voltage drop.
Pre-packaged canisters with conductive coke backfill lower anode-to-soil resistance and extend groundbed life for deep and shallow installations.
Test posts and remote-monitoring units let operators read structure potential and current output on demand — proving protection year after year.
A CP project follows a proven four-stage sequence. Ehisen supports you in every stage with engineering input and documented hardware.
Soil resistivity, water chemistry, coating condition and current demand are assessed, then anode geometry, quantity and rating are calculated for the design life.
Anodes, cables and canisters are manufactured with batch traceability, coating inspection and accelerated life testing per NACE TM0108-2008.
Groundbeds are drilled or excavated, anodes positioned with correct spacing, backfilled with coke breeze and connected with rated cables.
Potential readings are taken, rectifier output tuned, and test stations / monitoring installed so protection is verified and maintained over the asset life.
Buyers choose Ehisen because coating consistency, traceability and engineering response decide how long a CP anode really lasts — not just the catalogue price.
Coating applied on our own production line with a fixed formulation and controlled loading tolerance — samples and bulk runs are made to the same standard.
Every batch carries a LOT number linking substrate material, coating process records, inspection results and shipping documents.
Accelerated life testing per NACE TM0108-2008 at 10,000–20,000 A/m² converts laboratory hours into your operating rating.
Our engineers review soil resistivity, electrolyte and current demand, then recommend coating, geometry and quantity — within 24 hours.
Export experience across 40+ countries with complete documentation: MTC, coating reports, inspection records, certificate of conformity.
Production planned against your project schedule, with order status updates from coating to packing list.
A clear, three-step process keeps every CP order on specification and on schedule.
Share your application, environment, current demand and target life via WhatsApp or email — or send a drawing and we will extract the parameters.
Within 24 hours you receive a recommendation: anode format, coating system, dimensions, quantity and the supporting calculation basis.
After approval, production runs with batch QC, then ships with the full document pack: MTC, coating report, ALT data and packing list.
