| 1. Structure: The conveyor belt is composed of an inner rubber layer, multiple layers of fabric reinforcement, and an outer rubber layer. The braided suction hose is composed of an inner rubber layer, multiple braided fabric layers, a spiral steel wire reinforcing layer, and an outer rubber layer. Section II: Features: The rubber hose boasts excellent properties such as small outer diameter tolerance, oil and heat resistance, lightness, softness, and durability; the burst pressure of the rubber hose is four times the working pressure. Section 3: Application: Various types of reinforced rubber hoses (or suction) are manufactured using appropriate materials based on the conveying medium. These products have a reasonable structure design, excellent quality, and are sturdy and durable. They are flexible hoses used for conveying, suction (under vacuum conditions), various liquid粘流体, and powdered solid materials. Section 4: Technical Parameters of General Fabric Reinforced Hoses | |
