Ukuchaza Izixazululo Zokugeleza Ezithembekile Zezindawo Ezinobuthi Ezibhubhisayo – nguWomic Steel
Ukuxazulula Izinkinga Zangempela Zepayipi Ezimweni Ezilimazayo Nezicindezelayo
Ezindaweni laphoukugqwala okubangelwa yi-chloride, ukuqhekeka kokugqwala okucindezelekile, kanye nemithwalo ephezulu yemishiniukuhlala ndawonye, ukukhetha izinto ezingalungile zamapayipi kuholela ekuhlulekeni kwangaphambi kwesikhathi, ukuvalwa okungahleliwe, kanye nokwenyuka kwezindleko zomjikelezo wokuphila. Yilapho kanye laphoAmapayipi ensimbi engagqwali e-ASTM A789 / ASTM A790 S31803 aphindwe kabilibabonise inani labo langempela.
At Insimbi YaseWomic, siyakhiqiza futhi sihlinzekaAmapayipi ensimbi engagqwali e-S31803 angenamthungo futhi ahlanganisiwe ensimbi engagqwali ephindwe kabilihhayi njengomkhiqizo wezimpahla, kodwa njengomkhiqizoisixazululo sepayipi esiklanywe ngokugcwele, eklanyelwe ukusebenza ngokwethembeka ezindaweni ezisogwini lolwandle, amakhemikhali, ukukhishwa kukasawoti emanzini, kanye nezicelo zamandla.
Isisekelo Sobuchwepheshe: I-ASTM A789 / A790 kanye Nokulungiswa Kwezinto Zomhlaba Wonke
I-ASTM A789 kanye ne-ASTM A790 yizindinganiso zomhlaba wonke eziyinhloko ezilawulayoamapayipi ensimbi engagqwali amabilingensizakalo yokucindezela kanye nokumelana nokugqwala.
I-ASTM A789imboza amashubhu ensimbi engagqwali angenamthungo futhi ahlanganisiwe ukuze kube nenkonzo yokugqwala evamile.
I-ASTM A790zandisa lezi zimfuneko kumapayipi ahloselweukusetshenziswa kwamapayipi okucindezela, okushisa okuphezulu, kanye nokwakheka kwawo, okwenza kube yindawo eyinhloko yokubhekisela ezinhlelweni zokufaka amapayipi enqubo.
Izinga lensimbiI-UNS S31803imelela into yakudalaInsimbi engagqwali ye-duplex engu-22Cr, yakhelwe ukufeza cisheIsakhiwo esincane se-austenite esingu-50% kanye nesakhiwo esincane se-ferrite esingu-50%, okunikeza ibhalansi ephezulu yamandla kanye nokumelana nokugqwala.
Emhlabeni jikelele, i-S31803 ilingana nalokhu:
I-EN 1.4462 / X2CrNiMoN22-5-3
Ikilasi le-Duplex le-ISO 3183

Inzuzo Yobunjiniyela:
Uma kuqhathaniswa namazinga e-austenitic afana ne-316L, i-S31803 inikeza cisheamandla okukhiqiza aphindwe kabili, okuvumela ukwakheka kodonga oluncane, isisindo sesistimu esinciphile, kanye nokusebenza kahle kwengcindezi ephezulu.
Inqubo Yokukhiqiza: Ubuhle Obungenamthungo Nobuhlanganisiwe
Ukukhiqizwa Kwepayipi Elingenamthungo
Amapayipi e-S31803 angenamthungo akhiqizwa ngezinqubo zokubhoboza ezishisayo, ukunwebeka, kanye nokuqeda ngokubanda ngokunemba. Lo mzila uqinisekisa ukujiya kodonga okufanayo, ikhwalithi ephezulu kakhulu, kanye nokumelana nokucindezela okuphezulu, ikakhulukazi kumapayipi aqinile.
Ukukhiqizwa Kwepayipi Elihlanganisiwe
Kumapayipi ahlanganisiwe, iWomic Steel isebenzisaubuchwepheshe bokushisela be-TIG kanye ne-Plasma obunembile kakhulu, kusetshenziswa ukulawulwa kokugcwalisa kwe-duplex-grade ukuqinisekisa ukuthi ukumelana nokugqwala kwensimbi yokushisela kufana nezinto eziyisisekelo.ukuhlanza isixazululokuyimpoqo, ukubuyisela ibhalansi yesigaba se-duplex nokususa ukucindezeleka okusele.
Womabili amapayipi angenamthungo nashibiliwe adlula amazinga okuhlolwa kokugcina kanye nesitifiketi afanayo.
Ukwelashwa Kokushisa kanye Nobuchwepheshe Bokulawula I-Ferrite
Ukwelashwa okufanele ngokushisa kubalulekile ekusebenzeni kahle kwensimbi engagqwali kabili.ukufakelwa kwesisombululo ngokuvamile kungaphakathi kuka-1070–1120°C, kulandelwe ukucima amanzi ngokushesha. Le nqubo:
Incibilikisa izigaba eziyingozi ze-intermetallic
Ibuyisela ibhalansi ye-austenite-ferrite efanele
Kukhulisa ukumelana nokugqwala nokuqina
Okuqukethwe kwe-Ferrite kuqinisekiswa kusetshenziswa ukuhlaziywa kwe-metallographic kanye namathuluzi okulinganisa i-ferrite, okuqinisekisa ukuhambisana nezidingo ze-ASTM kanye nezincazelo ezithile zephrojekthi.
Ukuhlolwa, Ukuhlolwa, kanye Nokulandelela Okugcwele
Wonke amapayipi e-ASTM A789 / A790 S31803 ahlinzekwa yi-Womic Steel afakwa ngaphansi kwe-uchungechunge oluphelele lokuhlola, kufaka phakathi:
