Trvanlivost Kování JIC úzce souvisí s jejich výkonem při dlouhodobém používání. Oxidation and corrosion will not only affect the structural strength of the fittings, but may also cause leakage and performance degradation during system operation. To ensure that JIC fittings will not oxidize or corrode during long-term use, it is usually necessary to optimize and control them from multiple aspects such as material selection, surface treatment, and design structure.
Výběr materiálu je klíčovým faktorem při prevenci oxidace a koroze. Kvlákání JIC jsou obvykle vyrobeny z kovových materiálů s vysokou pevností, jako je nerezová ocel, měď a hliník. Tyto materiály mají silnou odolnost proti korozi, zejména z nerezové oceli, která funguje dobře v odolávání oxidace a koroze. Stainless steel contains a high proportion of chromium, which forms a protective oxide film on its surface, effectively preventing corrosion from external corrosive substances. For applications that require higher corrosion resistance, special alloys that are resistant to acid, alkali, or salt spray corrosion can be selected to adapt to more severe environmental conditions.
Kromě výběru materiálu hrají procesy povrchové úpravy také zásadní roli při prevenci oxidace a koroze. Mezi metody povrchového úpravy zahrnují postřik, protikorozní povlak, elektroplatování a eloxování. Through these processes, a protective film can be formed on the surface of the fittings to isolate air and moisture, preventing the metal from contacting oxygen, moisture or other corrosive substances in the environment. For example, the galvanizing process can effectively delay the oxidation of steel fittings, while electroplating or anodizing can form a hard oxide film on the surface of aluminum or copper fittings to provide additional protection. Anti-corrosion coatings such as epoxy resin coatings or polyurethane coatings can also effectively isolate moisture and corrosive chemicals, further enhancing the corrosion resistance of the fittings.
Pokud jde o návrh, mohou armatury JIC také snížit riziko oxidace a koroze optimalizací struktury. For example, through reasonable connection design, water accumulation and corrosive liquids can be avoided from being retained on the surface of the fittings, thereby reducing the source of corrosion. The design also needs to take into account the friction and collision that the fittings may encounter in actual use, which may damage the surface protective layer and expose the metal substrate. Therefore, the design can adopt the method of reducing the contact surface, or designing protective rings and sealing devices to prevent the metal surface from being directly exposed to the harsh environment.
Pravidelná údržba a péče jsou také důležitými vazbami, které zajistí, že armatury JIC nejsou oxidací a korozí ovlivněny po dlouhou dobu. Dokonce i příslušenství, které bylo přesně zpracováno, mohou být do jisté míry ovlivněny změnami faktorů prostředí v průběhu času. Regularly checking the surface condition of accessories and promptly discovering cracks, peeling or worn parts can effectively extend their service life. For accessories that are exposed to harsh environments for a long time, regular cleaning, lubrication and re-coating of anti-corrosion layers are also effective ways to maintain the corrosion resistance of accessories.
