It has the dual effect of withstanding positive and negative pressure. The tube body has good bending performance, and can be used normally under the condition of vacuum degree 60~80Kpa, without flattening, without delamination, and the tube body is solid. The inner rubber layer can resist the erosion of different media, and the outer rubber layer is resistant to weather aging and wear. The surface of the hose is corrugated surface and plane, and can also be made into outer armor form, and various forms of metal joints and assemblies can be configured according to user needs.
