description
3LPE steel pipe is a special anticorrosion structure for buried pipelines with three layers of materials sequentially coated on the outer wall of the pipe: the bottom layer is fusion bonded epoxy powder (FBE), which provides excellent adhesion and cathodic stripping protection; the middle layer is a copolymer adhesive, which ensures inter-layer adhesion; and the outermost layer is extruded-coated high-density polyethylene (HDPE), which provides excellent mechanical protection, impact resistance, and anti-soil stress performance. This composite structure greatly enhances the long-term corrosion resistance of the pipe in harsh environments.
Fusion-Bonded Epoxy (FBE) Primer (≥80μm): Provides cathodic disbondment resistance and adhesion.
Polymer Adhesive Layer (170–250μm): Bonds FBE to the outer polyethylene.
High-Density Polyethylene (HDPE) Topcoat (1.5–3.0mm): Offers mechanical protection and moisture barrier.
Designed for extreme environments (e.g., subsea, acidic soil, high salinity), it extends pipeline service life to ≥50 years with near-zero maintenance. Widely used in oil/gas transmission, water utilities, and chemical industries.

processus de production
application
Energy transmission: Long-distance onshore and subsea oil and natural gas transmission trunk lines, branch lines, and gathering pipelines. Urban gas networks. Oil pipelines.
Water Conservancy and Municipal Engineering: Large-scale water diversion and transmission projects (especially crossing sections and corrosive areas). Seawater desalination plant inlet and outlet pipelines. Municipal water supply and drainage main pipelines (with high corrosion resistance requirements). Hydropower station pressure pipelines.
Chemical and Industrial Applications: Process pipelines for transporting corrosive media (chemical raw materials, wastewater, slurry, tailings). Chemical water treatment pipelines. Power plant circulating water pipelines and demineralized water pipelines.
Harsh Environments and Special Projects: High-salinity alkaline soil, marshland, permafrost zones, and rocky areas. Horizontal directional drilling (HDD) and pipe jacking projects. Subsea pipelines (requiring enhanced-grade or higher specifications).
Structural Applications: Offshore platform pile legs, dock pile pipes, and underwater support structures for bridges.
avantages
Extreme corrosion protection: The three layers work together to build a strong barrier to effectively resist soil, water, chemicals and microbial corrosion, significantly extending the service life of the pipeline and greatly reducing the maintenance need.
Physical Protection: The tough HDPE outer layer provides superior resistance to impact, scratch, abrasion and soil stress, effectively protecting pipes from damage during transportation, installation (e.g. through rocks) and use.
Harsh Environment: Designed for extreme environments such as high salinity, frozen soil, swamps, rock areas, and seabed, with stable and reliable performance.
Excellent performance: the three-layer structure is tightly bonded, strong adhesion, and not easy to peel off; The coating surface is smooth, reducing the conveying resistance; Good electrical insulation, reducing the need for cathodic protection.
Cost-effective: Despite the high initial investment, its long service life and low maintenance costs provide better economics throughout the project lifecycle, especially for critical infrastructure.
emballage
Transportation of 3LPE steel pipe needs to focus on preventing and controlling deformation and coating damage. Customized curved saddle brackets are used to prevent displacement, collision and radial deformation. Sea transportation is optional:
Container transportation: suitable for short distance, small batch, good protection;
Bulk Carrier Deck Loading: Economical, requires specialized lashing to prevent movement;
Pipe Carrier: special ship for special transportation, highest efficiency and safety, high cost.
Select the optimal solution according to the transportation distance, batch size, cost and quality assurance requirements (especially coating integrity).
