wear resistant rubber hose(sandblast hose)

wear resistant rubber hose(sandblast hose) Industrial Wear Resistant Rubber Hose this type of rubber hose has a highly wear resistant inner layer.It is applied to wind pressure sand blasting and scotching on the metal surface in industrial production,and to conveyance of cement mortar,sand or other tiny particulate matters,or to other special places requiring high wearing resistance.It is also called wear resistant hose and usually fitted on the sand blasting machine to remove the rust on the ship,vehicle body and industrial,agricultural and construction machinery and equipment. 1.I.D.scope:1/2"-4" 2.Max.length:40m 3.W.P.:10-12bar 4.B.P.:30bar 5.Brand:MAXIANGDA 6.Applicable standard:DIN EN ISO 3861-1997 7.Technical parameters: 8.Anti-ozone aging:in the standard test chamber,concentration:50-/-5pphm,temperature:40+/-2°c;testing period:72t;without crack. 9.Heat-proof aging:in the standard aging chamber,temperature:70+/-1°c,Testing period:72t;tensile change:not more than -20°c,tensile stretch:not more than -40%. 10.Physical properties:tensile stretch of inner and outer rubber layer:≥300%,flexibility of hose is sound under-30+/-2°c for 5t,without craze crack or fracture after 180°c bending over or doubling;it is highly wear resistant. 11.Structure: A.Inner layer of hose:igh wear resistant polybutadiene blended rubber,applied to conveyance of low and medium speed fluid,high wear resistant natural rubber,applied to conveyance of high speed fluid.
