Suction rubber hose is widely used in industry, agriculture, mining, construction and other fields, mainly used for pumping or draining water, oil, sand, cement and other liquid or solid materials. It has the dual effect of bearing positive and negative pressure. The tube body has good bending performance, can be used normally under the condition of vacuum 60 ~ 80Kpa, no sucking flat, no delamination, and the tube body is strong. The inner rubber layer can resist the erosion of different media, the outer rubber layer is good for aging, wear resistance, the surface of the hose is corrugated and flat, it can also be made into external armor form, and various forms of metal joints and assemblies can be configured according to user needs.
