Made holes Hose: Diameter range :25-40 Uses: bridges, roads and other projects with construction hole on the bear rally has a good tearing performance 1.5-30Kg / root outer layer of glue. Class hose as a fabric hose. Selection of high quality elastic material, using advanced technology, a dedicated engineering system design and production holes hose has a smooth appearance, high tensile strength, the use of small deformation, very good, good abrasion resistance, flexibility. The whole root tearing Rally 2 times the working pressure, Pulling stretch up to 400%. Widely used in highways, railways and other prefabricated engineering system hole selection should be used in strict accordance with the working pressure, should be the best time of solidification Pulling. Storage should avoid contact with corrosive substances.
