Corrosion protection solutions by asset type
Five application areas, each with the corrosion mechanism explained, the recommended system configuration, and the application sequence drawn in section stage by stage. Every figure is taken from the corresponding Zhuohuang solution document.
Five application areas
These systems are chosen where a coating cannot be applied or cannot survive: complex geometry, surfaces that cannot be dried, assets that cannot be shut down, and details where film thickness cannot be controlled.
Storage Tank Base and Annular Plate
The shell-to-foundation joint is the shortest-lived detail on an above-ground tank — and hot work is normally not permitted.
Valves, Flanges and Buried Fittings
Film thickness cannot be controlled around a bolt head, and crevices between mating faces stay wet.
Buried Pipeline and Field Joints
Pipelines fail at the joints and the repairs, not in the mill-applied coating. Soil stress then works on whatever was applied.
Marine Steel, Piles and Splash Zone
Below the waterline the surface cannot be dried, so conventional coating systems cannot be applied at all.
Above-Ground Pipework and Structural Steel
Plant steel corrodes locally, not uniformly — at supports, fittings and bolted connections, where recoating means a shutdown.

Petrolatum, viscoelastic, microcrystalline wax, PE / PP pipeline tape and protective outer wraps — with specifications and data sheets for all fourteen products.
Where these systems are in service
Zhuohuang supplies end users, EPC contractors, applicators and distributors across Southeast Asia, the Middle East, Africa and North America, as well as the domestic Chinese market.

The regions column reflects where enquiries for each asset type most often originate. It is not a claim of installed reference projects in every territory listed — the projects we can evidence are listed, with client and date, on the project references page.
Send us the asset, we will propose the system
Asset type, dimensions, operating temperature, exposure and estimated quantity are enough for us to return a system configuration, a material estimate and the supporting documents.
