Reference information for product selection and cathodic protection engineering. Request project-specific datasheets and drawings from our technical team.
ISO 15589-1:2026
Current published ISO standard for cathodic protection of on-land pipeline transportation systems.
ISO official page →ASTM A518/A518M
Standard specification for corrosion-resistant high-silicon iron castings. ASTM identifies Grade 3 as recommended for impressed-current anodes.
ASTM official page →ASTM B418
Standard specification for cast and wrought galvanic zinc anodes for suitable cathodic protection environments.
ASTM official page →From project conditions to product selection
Product selection should follow the project requirements rather than a catalogue rating alone.
Define the asset
Structure, coating, geometry, continuity, environment and exposure.
Establish demand
Determine current demand, design life and applicable protection criteria.
Select the system
Compare anode type, layout, backfill, power supply and monitoring arrangement.
Verify documents
Confirm drawings, material data, ratings and project standards before release.
Datasheets & drawings
For the final website, downloadable PDF datasheets should be added only after the corresponding document has been verified by OuChuang. This avoids publishing incorrect dimensions, alloy chemistry, electrical ratings or performance claims.
