⚙️Technical Breakthroughs: Bidirectional Stretching Process Reshapes Pipeline Performance Benchmarks
Technical Barrier Breakthrough: Exclusive two-step process achieves integrated R-port forming, with higher orientation degree and leading hydrostatic performance. PVC-O pipes (biaxially oriented polyvinyl chloride pipes) use molecular-level bidirectional stretching technology to make polyvinyl chloride molecules orderly arrange in both axial and radial directions, forming a high-strength network structure. This process brings three leaps in pipe performance:
Process Originality: Complementary one-step and two-step technologies, with orientation degree improved to international top levels
Impact resistance increased by over 10 times, far exceeding traditional UPVC pipes, capable of withstanding rock extrusion in mines and mechanical stress in trenchless construction
Pressure-bearing capacity breaks through 2.5MPa, ring stiffness reaches industry-leading level (≥16kN/m²), suitable for high-pressure water supply main networks
Wall thickness reduced by 35%-40%, significantly lowering raw material costs under the premise of ensuring performance, with comprehensive production costs reduced by ≥35%
Blesson’s PVC-O pipe extrusion production line is equipped with a cutting-edge online double-heating oven socket equipment specially designed for PVC-O pipes, integrating the latest technological innovations to ensure excellent quality and reduce the rejection rate by 40%.
Market Applications: Full-scene Coverage Drives Hundreds of Billions of Incremental Demand Relying on the strategic cooperation with state-owned Tianyuan Group, Blesson has achieved mass production of Φ110mm to DN800mm full specifications, helping customers seize emerging market dividends:
