317, 317L umtshintshi wobushushu wensimbi engenasici
Inkcazo yezinto eziphathekayo
- Inkcazo yezinto eziphathekayo
Yintsimbi engatyiwa yi austenitic enexabiso eliphezulu lechromium, nickel kunye nemolybdenum element enika isakhono esigqwesileyo sokumelana nomhlwa.Inokumelana okuphezulu kwiziphumo zeekhemikhali ezivela kwi-acids ezahlukeneyo.I-alloy 317L ngumxholo ophantsi wekhabhoni ovumela ukuchasana nokubola kwe-intergranular.Inamandla aphezulu okuzibamba kumaqondo obushushu aphezulu.Iyakwazi ukuwelda kunye nayo yonke inkqubo ye-welding esemgangathweni kwaye iphathwa ngokulula ngoomatshini abaqhelekileyo. - Idatha yokwenziwa
Ezi zishushu zisetyenzwa kusetyenziswa yonke inkqubo esemgangathweni yokusebenza eshushu.Ifudumeza kumaqondo obushushu phakathi kwe-1149 ukuya kwi-1260 idigri C. Iqondo lokushisa kufuneka ligcinwe ngaphantsi kwe-927 degrees C. Inkqubo yokucoca emva komsebenzi ifakwe kuyo ukuze igcine iimpawu eziphezulu zokuxhathisa ukubola.Ngaphezu koko, le nkqubo yenziwa ukunciphisa uxinzelelo lwangaphakathi.Iityhubhu ze-SS zizotywa ngokulula kunye nokusebenza okubandayo.Ukunyangwa kobushushu akuyi kuchaphazela isakhiwo, nangona kunjalo, ukusebenza okubandayo kulandelwa ukufumana izakhiwo ezinzima.
Ukuvalwa kwesisombululo kwenziwa kumaqondo obushushu aphakathi kwe-1010- 1121 degree C kwaye kulandelwe kukupholisa.Iphantsi kwenkqubo yokugqiba kwimizi-mveliso ukufumana imilinganiselo echanekileyo kunye nokugqitywa komphezulu. - Ulawulo lomgangatho
Iqela lethu lonke lihlawulwe ngokutsha ukuze lixhase ukuzibophelela komgangatho.Amandla ethu angundoqo liqela elizinikeleyo nelikhuthazayo.Sizinikezele ekunikezeni iimveliso kunye neenkonzo ezikumgangatho ophezulu kubathengi.Njengoko singababoneleli behlabathi, silinganisa iimveliso zethu ngemigangatho evunyiweyo kumazwe ngamazwe ukuqinisekisa umgangatho weemveliso.Uvavanyo lokuqina, uvavanyo lwe-thermal conductivity, uvavanyo lokuvuza, uvavanyo lwezinto ezibonakalayo, uvavanyo lwe-intergranular corrosion, kunye novavanyo lomatshini, uvavanyo olunikiweyo, lwenziwa sithi kwinqanaba lokuqala.
Uhlolo lokugqibela lwenziwa ngabasemagunyeni beqela lesithathu.Ngapha koko, uvavanyo lwesibini luvavanyo olutshabalalisayo, uvavanyo loxinzelelo, uvavanyo lwe-tensile kunye nokunye okuninzi.
I-Stainless Steel 317 / 317L I-Heat Exchanger Tubes ifumaneka kwiindidi ezahlukeneyo zokugqitywa, umntu unokuzifumana kuthi.
