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.
