Threaded rubber joint is composed of a rubber sphere and two metal parallel movable joints. This kind of threaded soft joint is mainly used for steel pipe, copper pipe and high pressure connection, the thread of welded steel pipe is currently mostly operated by set of thread machine, and about the thread processing accuracy and appearance roughness we require in very high pressure pipeline with lathe clamping down. The damage of threaded rubber joints is smaller than that of other rubber joints, but the reason for reducing damage comes from the size of the type. The small size of threaded rubber joints and the fact that they can only be manufactured to DN80 makes them able to withstand the pressure in the pipeline, which makes them much less likely to burst and suck flat. In the installation, please pay attention to the need to connect the two ends of the pipe fittings on the horizontal surface, the installation needs to first screw the threaded structure in lifting a section of the pipe fittings, and then screw the other section of the pipe fittings, always keep in the horizontal surface, to avoid uneven force during the installation process and lead to tearing the rubber joint, the next hand or wrench to tighten the screws to the two ends of the threaded rubber joint box pipe fittings Fixed on objects that are not easily stretched or perhaps distorted. Selection should be based on the ambient temperature selection of materials -20°C~80°C choose natural rubber, which is the most common flexible rubber joint material, basically no special requirements will be used in the case of this rubber material, good pressure change performance, wear resistance and tensile properties. -20°C~120°C EPDM rubber is used. This rubber material is vulcanized by organic peroxide up to 120°C, with high temperature steam resistance and low gas permeability. In addition to this rubber also has a certain degree of resistance to weak acid and alkali performance, for some slight degree of acid and alkali installation environment has good adaptability. -25℃～180℃ choose fluorine rubber, excellent high temperature resistance, good aging resistance, excellent mechanical properties, good electrical properties, good permeability.
