Supplier's note

  1. Technical Breakthroughs:

    • Pressure Efficiency: The Pro Model’s 0.026MPa rating exceeds industry benchmarks by 30%, enabling high-stress curing without deformation.
    • Material Innovation: The Advanced Model’s reinforced rubber blend extends lifespan by 20% in abrasive environments.
    • Scalability: Customizable diameters reduce project downtime by adapting to site-specific pipe requirements.

  2. Optimal Version Selection:

    • Base Model: Best for standard pipe diameters (Φ800mm) and low-pressure applications like residential drainage.
    • Advanced Model: Ideal for contractors needing flexibility (e.g., Φ720–900mm pipes) or working with abrasive concrete mixes.
    • Pro Model: Choose for industrial-scale projects requiring extreme durability and pressure resistance, such as tunnel linings.

With the Pro Model’s 0.026MPa pressure rating, you can ensure structural integrity in high-stress curing environments. Pair its composite material with adjustable sizing to create custom pipe solutions tailored to your project’s demands.
