Isici sokusebenza:
Impahla eyinhloko ye-valve ye-duplex stainless teel check valve iyingxenye yesigaba se-ferrite kanye nesigaba se-austenite esakhiweni sesisombululo esiqinile esisekelwe ensimbi, kodwa insimbi enokuqukethwe kwesigaba esincane esingaphezu kuka-30% ibizwa ngokuthi i-duplex stainless steel, engcono kakhulu. ukusebenza kwe-duplex steel Ukwakheka okuqukethwe kwe-ferrite kungu-60% -40%, okuqukethwe kwe-austenite kuphakathi kuka-40% -60%, noma yikuphi-ukuncipha okukhulu komzimba kuzobangela ukusebenza kwensimbi yesigaba esikabili ukuba buthaka.I-valve yokuhlola insimbi yesigaba esikabili ine-plasticity enhle nokuqina, ukuhamba kahle kokushisa, i-coefficient encane yokwandisa umugqa, ukucindezeleka okuncane kwe-welding kanye nokuguqulwa, namandla aphezulu kanye nokumelana nokugqwala kokucindezeleka kwe-ammonia ion.Uma kuqhathaniswa namavalvu okuhlola ensimbi engenasici e-austenitic, afana no-304. 304L, 316, 316L, njll. avame ukulinyazwa ukugqwala kwendawo okufana nokugqwala kwe-intergranular, ukugqwala kwe-pitting, ukugqwala kokuqhekeka, ukugqwala kwengcindezi, njll. Uhlobo lokugqwala lubonisa ukugqwala okuqinile ukuphakama, nokumelana kwayo nokukhathala kokugqwala nakho kunamandla kakhulu.
Isicelo:
Ngokumelana okuhle nokukhathala kokugqwala nokuguga nokusebenza kokugqwala.Ngaphansi kwesimo semidiya ethile ebolayo, ilungele ukwenza amaphampu, ama-valve nezinye izinto zamandla.
