When a bite type tube fittings needs to be used in a high temperature or corrosive environment, it should be noted that a bite type tube fittings made of a high temperature resistant and corrosion resistant material should be selected. For example, stainless steel (such as 316L stainless steel) is an ideal choice for such environments due to its good corrosion resistance and high temperature resistance. For a bite type tube fittings with a 24° cone and an O-ring seal, the material of the O-ring is equally important. It is necessary to select high temperature resistant and chemical resistant materials such as fluororubber (Viton) or silicone to ensure good sealing performance in high temperature or corrosive media.
When designing the system, the effects of high temperature and corrosive environments on bite type tube fittingss should be taken into account to ensure that the fittings can withstand the expected temperature and pressure and leave enough safety margin. Installation should be carried out strictly in accordance with the manufacturer's instructions to ensure that the end faces of the pipes are flush, burr-free, and clean. During pre-installation, the coaxiality of the pipe and the fitting body should be maintained to avoid seal failure due to deflection. When tightening the nut, it should be done according to the specified tightening torque to avoid over-tightening or over-loosening. Too tight may cause the ferrule to deform and affect the sealing performance; too loose may cause leakage.
In high temperature or corrosive environment, the sealing performance and appearance of the ferrule pipe joint should be checked regularly. If leakage, deformation or damage is found, it should be handled in time. According to the use environment and conditions, a reasonable replacement cycle should be formulated to regularly replace the aged O-rings and possibly damaged joint parts. An emergency plan should be formulated to deal with emergencies caused by high temperature or corrosive environment, such as leakage, explosion, etc.
When operating in a high temperature environment, appropriate protective equipment should be worn to avoid direct contact with high temperature parts to prevent burns. In a corrosive environment, in addition to selecting corrosion-resistant materials, you can also consider applying an anti-corrosion coating on the surface of the joint or adopting other anti-corrosion measures. During installation and use, relevant international standards and specifications, such as DIN2353/ISO8434, should be strictly observed to ensure the performance and safety of the product.
When it is necessary to use a ferrule pipe joint in a high temperature or corrosive environment, it is necessary to comprehensively consider multiple aspects such as material selection, design and installation, maintenance and inspection to ensure the performance and safety of the joint.
