Ekusetshenzisweni okungokoqobo kwamapayipi emishini, imikhiqizo eminingi yenziwe ngensimbi engagqwali noma ihilelekeizinto zensimbi engagqwali.Nakuba zonke zingezensimbi engagqwali, kunezinhlobo ezahlukene zensimbi engagqwali, njengamamodeli angu-304 no-316.Amamodeli ahlukene anezakhiwo ezihlukene zomzimba
Umehluko phakathi kuka-316 insimbi engagqwali ne-304 insimbi engagqwali
1. Ukwakheka kwamakhemikhali
304 insimbi engagqwali: iqukethe 18% chromium kanye 8% nickel, kanye nenani elincane carbon, manganese, ne-silicon.
316L insimbi engagqwali: iqukethe 16% chromium, 10% nickel, kanye 2% molybdenum, kanye nenani elincane carbon, manganese, ne-silicon.
2. Ukumelana nokugqwala
I-304 insimbi engagqwali: Inokumelana nokugqwala okuhle, ikakhulukazi kumkhathi ovamile, amanzi, nemidiya yamakhemikhali enozinzo oluhle, kodwa ijwayele ukugqwala nokugqwala kwe-intergranular kumidiya equkethe ama-ion e-chloride.
316L insimbi engagqwali: Inokumelana nokugqwala okungcono kunensimbi engagqwali engama-304, ikakhulukazi yemidiya equkethe ama-ion e-chloride, indawo ene-asidi ne-alkaline, enokuqina okuhle.
3. Amandla nobulukhuni
304 insimbi engagqwali: inamandla amahle nobulukhuni, kodwa iphansi kancane kune-316L yensimbi engagqwali.
316L insimbi engagqwali: Uma iqhathaniswa 304 insimbi engagqwali, inamandla aphakeme nobulukhuni.
4. Ukusebenza kwe-Welding
I-304 insimbi engagqwali: Ine-weldability enhle futhi ingasetshenziselwa izindlela eziningi zokushisela, kodwa ijwayele ukugqwala phakathi kwe-intergranular ngaphansi kwezimo zokushisa eziphezulu.
Insimbi engagqwali engu-316L: Uma iqhathaniswa nensimbi engagqwali engu-304, kunzima ukuyishisela, kodwa inokusebenza okuhle kokushisela ngaphansi kwezimo zokushisa eziphakeme futhi ayijwayele ukugqwala phakathi kwegranular.
5. Ukwehluka kwentengo
Uma kuqhathaniswa ne-carbon steel, insimbi engagqwali ibiza kakhulu, kuyilapho insimbi engagqwali, i-316 insimbi engagqwali ibiza kakhulu, ikakhulukazi ngenxa yezindleko zokukhiqiza eziphakeme kanye nempilo ende yesevisi, ngakho intengo izobiza kakhulu.
6. Ububanzi bokusetshenziswa
Insimbi engagqwali 316 inobubanzi obubanzi bezicelo uma kuqhathaniswa nensimbi engagqwali 304. Isibonelo, insimbi engagqwali engu-316 ingasetshenziswa embonini yokudla, kuhlanganise nemishini yezokwelapha, futhi ingadlala indima ebalulekile.
Ububanzi bokusebenza bensimbi engagqwali engu-304
Insimbi engagqwali 304, njengohlobo oluvamile lwensimbi, lusetshenziswa kabanzi ezicini eziningi ngenxa yokumelana nokushisa okuphezulu nokumelana nokugqwala.Ngakho kwezinye izindawo ezimanzi, ukukhetha insimbi engagqwali engu-304 kungaqinisekisa ukumelana nokugqwala isikhathi eside, njengoba kungasetshenziswa ukwenza amapayipi ensimbi anokumelana nokugqwala okuqinile.Lesi futhi isizathu esenza ukuthi kukhethwe amapayipi amaningi ensimbi engagqwali angu-304 ukuze kuthuthwe amapayipi.
Phakathi kwemikhiqizo yenkampani yethu, ezivame kakhuluama-flange ensimbi engagqwali, izinsimbi zamapayipi ensimbi engagqwali, kanyeamapayipi ensimbi engagqwali.
