Izigaba ezintathu nemiphumela kwinqubo yokunxusa

Enqubweni yokwakha insimbi engagqwali, 'anneling ' inqubo ebalulekile. Ukunikezwa kwemali kudinga ukusetshenziswa kwama-annealing foracing, izimlilo ezikhanyayo ezisetshenziselwa ukwelashwa okuqediwe kwensimbi engenasici endaweni yokuvikela. Ukusebenza kuhlukile, izidingo zezinto ezivelelayo ezivelelayo zihlukile, futhi imboni yokwelashwa kokushisa ayifani. Inqubo ejwayelekile yokwelashwa kokushisa kuka-300 Series Auntenitic stainless stainless stinanless Pipe Ipayipi liqinile lokwelashwa kwesisombululo. Isihluthulelo sale nqubo yokushisa yokushisa ukupholisa ngokushesha, kusuka ngo-1050 kuye ku-1150 ° C, ukulondolozwa kokushisa okulungile kwesikhathi esifushane, bese kuthi ikhebule lichungechunge olufushane lwe-auston, bese ngokushesha lube sehlelwe ngaphansi kwesikhashana esingu-35 ° C.00.

Futhi, izigaba ezintathu ze- '' zizokwenza indawo yakho yepayipi yensimbi ibe nzima futhi isebenze kanzima. Okokuqala, isiteji sokushisa, ipayipi lensimbi elingenasici lisesithandweni esivaliwe, futhi kuyadingeka ukuqinisekisa ukuthi isikhundla sepayipi nepayipi lokuphuma sigcinwa sivaliwe futhi akukho ukuvuza komoya okuvunyelwe. Ngoba kufuthelwa emkhathini onciphisayo we-inert gesi kanye ne-hydrogen ejwayelekile, izinga lokushisa elithile lifinyelelwa, futhi okusanhlamvu kwensimbi kubuyiselwe emfanisweni nasesimweni esihle. Okwesibili, isigaba sokufakelwa, izinga lokushisa lepayipi lensimbi elingenasici lifakwa futhi lizinzile isikhathi esithile ngesigaba sokufakwa, ukuze siqede ngempumelelo ukugcwala kwe-Christium ye-chromium futhi uvikele ukukhiqizwa kokugqwala kwe-intercrystalline. Ipayipi lensimbi ngemuva kokulashwa kokuzinza inezakhiwo ezingcono zokwelapha kanye nokuphikiswa kokugqwala. Okwesithathu, isiteji esipholile, ipayipi lensimbi engenasici lisebenzisa i-hydrogen esithandweni esivaliwe ukufeza umphumela wokupholisa okusheshayo, isistimu yamanzi ejikelezayo isuse ukushisa kanye ne-decarbonatenization, futhi uthole indawo ngaphandle kwe-oxidation kanye nokuphikiswa okuhle kokugqwala.

Enqubweni yokuncibilikisa, kukhona nezidingo ezithile zesithando somlilo, futhi kufanele kubhekwe ekuvikeleni isithando somlilo. Isithando somlilo sisebenzisa i-hydrogen njengegesi evikelayo. Lapho i-hydrogen ivuza, kungaba yingozi ukukhuphuka futhi iqole ekwakhiweni kombhoshongo. Ngakho-ke kufanele sithathe izinyathelo ezifanele zokuqinisekisa ukuphepha.
