Key Advantages

Superior Corrosion Resistance

Utilizing high-grade FBE and 3LPE/PP to prevent oxidation and chemical erosion in aggressive soils.

Extended Service Life

Multi-layer protection ensures stability over decades, reducing the frequency of pipeline replacements.

Mechanical Robustness

Strengthened type coatings provide exceptional resistance to impact and abrasion during installation.

High Insulatibity

Advanced dielectric properties effectively isolate the steel pipe from stray currents and soil electrolytes.

Flow Optimization

Internal drag-reducing coatings minimize friction, lowering energy consumption for pumping systems.

Precision Application

Centrifugal coating technology ensures uniform thickness and total coverage for inner wall protection.

Frequently Asked Questions

Q: What is the difference between 2-layer and 3-layer PE coating?

3-layer coating includes an additional adhesive layer between the FBE primer and the PE outer shell, providing superior bonding and enhanced corrosion protection compared to 2-layer systems.

Q: Which coating is best for high-temperature liquid transport?

PP (Polypropylene) coatings are generally preferred over PE (Polyethylene) for higher temperature applications due to their superior thermal stability.

Q: How does inner drag-reducing coating save costs?

By reducing the friction between the liquid and the pipe wall, it lowers the energy required for pumping and minimizes internal erosion, reducing long-term maintenance costs.

Q: What are the available sizes for inner corrosion protection?

We offer inner wall corrosion protection for steel pipes ranging from DN100mm up to DN700mm.

Q: Is FBE coating suitable for all soil types?

Yes, FBE is highly versatile, but for soils with high mechanical stress or extreme abrasion, we recommend strengthened type FBE or 3LPE coatings.

Q: Can you provide custom inner paint designations?

Absolutely. In addition to red oxide and bicomponent liquid epoxy, we can apply any specific paint designated by the client via centrifugal coating.
