Nominal inside diameter: DN12-DN200 wall thickness (mm): 4-12mm Material: SBR Manufacturers (Origin): Hengshui Ward uses: sweeper rubber suction hose used for road sweeper, efficient vacuum trucks (pure suction sweeper) and purification equipment suction dust, gas, ash and other debris. Length (m): 1-20m We use thin-walled spiral steel skeleton reinforced cloth rubber hose, this hose has good flexibility and scalability of capacity, our products than similar soft plastic vacuum soft market tube has better resistance to aging and weathering properties. Product Name: sweeper rubber suction hose product structure: sweeper rubber suction hose wear and aging from the inside layer, fabric reinforced layer, an intermediate layer spiral steel skeleton and the outer layer consisting of anti-aging products use: sweeper rubber suction hose used in road sweeper, efficient vacuum trucks (pure suction sweeper) and purification equipment suction dust, gas, ash and other debris. Advantages: sweeper rubber suction pipe has excellent resistance to aging, wear and excellent stretchability. Product Working pressure: sweeper rubber suction hose generally no higher than 4bar conditions allow low pressure environment, special circumstances will need to withstand a certain negative, namely vacuum.
