主要由耐液体的合成橡胶内胶层、中胶层、Ⅰ、Ⅱ、Ⅲ层钢丝编织层、耐天候的合成橡胶外胶层组成，内胶层具有使输送介质承受压力，保护钢丝不受侵蚀的作用，外胶层保护钢丝不受损伤，钢丝层是骨架材料，起增强作用。
It mainly consists of liquid-resistant synthetic rubber inner layer, medium rubber layer, steel wire braiding layer I, II, III and weather-resistant synthetic rubber outer rubber layer. The inner rubber layer can make the conveying medium withstand pressure and protect the steel wire from erosion. The outer rubber layer can protect the steel wire from damage. The steel wire layer is a skeleton material and plays a reinforcing role.
