Key Advantages

Superior Corrosion Shield

Advanced FBE and PE/PP layers provide an impenetrable barrier against aggressive soil and liquid chemicals.

Extended Service Life

High-durability coatings significantly prolong the pipeline's lifespan, reducing the need for premature replacement.

Mechanical Resilience

Strengthened PE/PP coatings offer exceptional resistance to abrasion and mechanical impact during installation.

Optimized Flow Rate

Internal drag-reducing coatings lower friction, increasing throughput and reducing pumping energy costs.

Precise Application

Utilizing centrifugal coating for inner walls ensures a uniform thickness and total coverage for DN100-700mm.

Versatile Customization

Tailored coating thickness and material selection to meet specific engineering standards and environmental conditions.

Frequently Asked Questions

Q: What is the main difference between 2LPE and 3LPE coatings?

3LPE includes an additional FBE primer layer between the steel and the PE topcoat, providing superior adhesion and a more comprehensive corrosion barrier compared to 2LPE.

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

3LPP (Polypropylene) is generally recommended for higher temperature environments as it maintains mechanical properties and stability better than PE coatings.

Q: How does internal coating reduce investment and maintenance costs?

Internal drag-reducing coatings minimize fluid friction, which lowers energy consumption for pumps and prevents internal corrosion, extending the interval between repairs.

Q: What is the typical thickness for a strengthened 3LPE coating?

For strengthened 3LPE/3LPP coatings, the minimum thickness is typically 2.5mm to ensure maximum resistance to mechanical damage during burial.

Q: Can you provide customized inner coatings for specific chemicals?

Yes, while we offer standard red oxide and bicomponent liquid epoxy, we can apply other paints designated by clients via our centrifugal coating process.

Q: What is the application range for your internal corrosion protection?

Our inner corrosion protection services are currently optimized for steel pipes with diameters ranging from DN100 to DN700mm.
