About Oil Resistant Rubber Joint
Common rubber joint is easy to expand in the oil medium, so the material choosing for the rubber joint of oil medium is always a difficult problem. Special oil resistant rubber joint for oil pipeline system mainly choose nitrile rubber, synthesis of butyl rubber and natural rubber, ect. After the experiment from experts deployment appropriate proportion, developed super oil resistant rubber material, which makes the traditional polybutadience rubber of oil resistant performance has been greatly improved and enhanced. At the same time, the service life and other performance of the soft joint used in hydraulic oil are improved.
Rubber joint normal applicable medium is the ordinary water of temperature 0-80 DEG C, if used in particular medium, for example: oil, acid and alkali, high temperature and other corrosion and texture hard situation should choose relative deserve special refractory material for rubber joints, not blindly on or general.
When the pipeline displacement amount is greater or equal to the maximum compensating amount of the rubber joint then more rubber joints are needed to fit the displacement. It is strictly prohibited to adjust the pipeline cause the oil resistant rubber joints in the limit of the flexural displacement and deviation of the state, cannot excessive it either(stretching, displacement, deflection, etc.).
