2.液压性能
排泥橡胶软管在1.5倍于规定的工作压力下进行定压试验时，应无渗漏、局部鼓泡等其它异常现象。
排泥橡胶软管工作压力有特殊要求的，由需方确定，供方设计，爆破压力不低于工作压力的3倍。
排泥橡胶软管在管体变形试验时，其长度和外径变化率应符合表2的规定。
2.Hydraulic Properties：
The draining rubber hose shall be no abnormal change such as leakage or partial bulging when tested under stable pressure of 1.5 times higher than rated working pressure.If the buyer has specific requirements on working pressure of draining rubber hose, we can design as per the buyer's designation, the explosive pressure shall not be 3 times lower than rated working pressure.
When executing the deforming test to draining rubber hose, the variance on length and outer diameter shall not go beyond the data as listed in Form2.
