Anti-corrosion Technology & Manufacturing Process
Core Anti-corrosion Technologies (Optional)
3PE Anti-corrosion: Polyethylene (PE) outer layer + Adhesive layer + Epoxy powder inner layer, corrosion resistance, wear resistance, suitable for underground, wet and harsh environments.
2PE Anti-corrosion: PE outer layer + Adhesive layer, cost-effective, suitable for general corrosion environments such as municipal water supply and drainage.
FBE (Fusion Bonded Epoxy): High adhesion, excellent chemical corrosion resistance, suitable for chemical industry and high-corrosion fluid transportation.
Epoxy Resin Coating: Food-grade optional, non-toxic, suitable for drinking water, pharmaceutical and food processing industries.
Anti-rust Oil Coating: Simple and practical, suitable for short-term storage and general dry environment.
Manufacturing Process
Steel Strip Uncoiling → Slitting → Edge Trimming → Straight Seam Forming → High Frequency Induction Welding → Weld Grinding (Inside & Outside) → Sizing → Straightening → Cutting → Base Pipe Inspection → Anti-corrosion Treatment (Derusting → Coating → Curing) → Final Inspection → Packaging
Strict Quality Inspection
Base Pipe Inspection: Chemical composition, mechanical properties, hydraulic test, dimensional and surface inspection (EN 10217 standard).
Anti-corrosion Layer Inspection: Coating thickness, adhesion test, impact test, corrosion resistance test (salt spray test, acid-base test).
Overall Inspection: No cracks, peeling, bubbles or slag; Dimensional accuracy meets requirements; Pressure-bearing capacity is up to standard.
Product Advantages
Superior Anti-corrosion Performance: Advanced anti-corrosion technology effectively resists corrosion from water, soil, chemicals, salt spray and other media, greatly extending service life (service life up to 30-50 years under normal use).
Compliance with High Standards: Base pipe meets EN 10217 standard, anti-corrosion layer meets international anti-corrosion standards, fully suitable for EU and global markets.
High Reliability: Straight seam HFW welding ensures strong weld, uniform structure and good pressure-bearing capacity; anti-corrosion layer has high adhesion and wear resistance, not easy to fall off.
Versatility: Various anti-corrosion options and steel grades available, adapting to different working conditions (underground, marine, chemical, low/high temperature).
Cost-saving: Long service life reduces maintenance and replacement costs, suitable for large-scale engineering projects and long-term use.
Easy Installation: Precise dimensional tolerance, smooth surface and anti-corrosion layer, convenient for connection and construction.
Application Fields
Municipal & Public Utilities: Underground water supply and drainage pipelines, urban gas transmission pipelines, sewage treatment pipelines, which are resistant to soil corrosion and long-term buried use.
Petroleum & Natural Gas Industry: Oil and gas gathering and transportation pipelines, offshore oil and gas pipelines, gas station supporting pipelines, resistant to oil and salt water corrosion.
Chemical & Petrochemical Engineering: Chemical fluid transmission pipelines, acid-base and solvent transportation pipelines, resistant to chemical medium corrosion.
Marine & Coastal Engineering: Ship pipelines, offshore platform fluid pipelines, coastal water supply pipelines, resistant to salt spray and marine environment corrosion.
Power & Energy Industry: Power plant circulating water pipelines, boiler feedwater pipelines, resistant to high-temperature and water corrosion.
Water Treatment & Environmental Protection: Sewage treatment, desalination pipelines, drinking water transmission pipelines (food-grade anti-corrosion optional).
