squeeze pipe for concrete pump

Squeeze pipe for concrete pump is mainly composed of an inner rubber layer, middle rubber layer, 2, 4, and 6 layers of steel wire winding reinforcement layer, and outer rubber layer. The inner rubber layer has the function of maintaining the pressure of the conveying medium and protecting the steel wire from erosion. The outer layer protects the steel wire from damage, and the steel wire layer (φ0.3–2.0 reinforced wire) layer is the reinforcement of the skeleton material.
