  • Product Description
  • Product Overview:

    Made from multiple high-quality spring steel plates and subjected to a special quenching and tempering heat treatment process, these components exhibit exceptionally high elasticity, toughness, fatigue resistance, and outstanding wear resistance. They also feature extremely high rigidity and compressive strength, superior durability and wear resistance, stable sealing performance, as well as guiding and stabilizing functions.

    Application scenarios and operating conditions:

    Tunnels with high water pressure, great burial depths, long tunneling distances, and large-diameter shield tunnels—environments in which the tail seal of the shield is subjected to extremely high external pressures. In such geologic formations as water-rich sand layers, gravel layers, and rock strata, the sealing brushes face intense abrasive wear. The exceptional wear resistance of steel plate brushes ensures the long-term durability and reliability of the sealing system even under these harsh geological conditions.
