The so-called steel wire refers to the reinforced steel wire at both ends of the rubber hose body. This steel wire serves the function of preventing detachment, avoiding the rubber disk from slipping out of the flange groove, and reinforcing the joint. However, there is no steel wire inside the middle part, as shown in the following image:
As shown in the above diagram, the internal structure mainly consists of three major components: the inner rubber layer, the skeleton layer, and the outer rubber layer. The inner rubber layer provides protection, while the outer rubber layer prevents aging. The middle skeleton layer bears the pressure. All rubber joints produced by Songjiang Group use polyester cord fabric consistent with tire skeleton layers. The thickness and layers are increased to ensure reliability. Songjiang Group’s rubber joints undergo pressure testing at 1.5 times the national standard, effortlessly achieving excellent results.
