Core Product Advantages
High Structural Quality for Construction Engineering
The ERW steel base pipe adopts advanced high-frequency welding and online shaping technology, with uniform pipe body size, smooth weld surface and no welding defects. After strict stress relief treatment and 100% non-destructive welding inspection, the pipe features high structural rigidity, strong pressure resistance and stable mechanical performance. It can adapt to complex construction site laying, foundation backfilling and structural matching requirements, avoiding deformation and damage during construction.
Dual Anti-corrosion Solution for Construction Scenarios
Matching two mature anti-corrosion systems to meet differentiated construction needs: 3PE coating has excellent impact resistance and anti-soil extrusion performance, suitable for conventional building buried pipelines and outdoor long-term laying; FBE coating features super chemical resistance and anti-aging performance, ideal for construction sites with humid, high-salt and polluted environments. Both coatings effectively prevent pipeline rust, perforation and leakage during long-term building operation.
Excellent Construction Adaptability
The product has precise dimensional tolerance, good pipe body straightness and flexibility, supporting on-site arbitrary cutting, welding and assembly. It adapts to complex construction layout, cross laying and foundation embedding operations. The anti-corrosion coating has strong scratch resistance, which can resist minor mechanical friction and impact during construction transportation and installation, reducing on-site damage rate.
Long Service Life & Low Project Cost
High-quality coating and strict manufacturing standards ensure the pipeline service life up to 30–50 years in construction engineering environments. It avoids frequent maintenance, replacement and secondary construction problems, greatly reducing the overall investment and later operation cost of construction projects, with extremely high engineering cost performance.
