Ubuchwepheshe bokucubungula nokwenza amapayipi anemba ensimbi engenasici asebenza kahle ahlukile kumapayipi endabuko angenamthungo. Izikhala zamapayipi endabuko angenamthungo ngokuvamile zikhiqizwa ukubhobozwa okushisayo okuyi-roll-rolling cross-rolling, futhi inqubo yokwenza amapayipi ngokuvamile ithatha inqubo yokwenza umdwebo. Amashubhu ensimbi engagqwali anemba ngokujwayelekile asetshenziswa kumathuluzi anembayo noma kumishini yezokwelapha. Akukhona nje kuphela ukuthi amanani aphakeme kakhulu, kodwa futhi ngokuvamile asetshenziswa kumishini eyinhloko namathuluzi. Ngakho-ke, izidingo zezinto ezibonakalayo, ukunemba kanye nokuqedwa kwangaphezulu kwamashubhu ensimbi engagqwali ngokunemba ziphezulu kakhulu.
Izikhala zeshubhu zezinto ezisebenza kanzima ukwenza izinto ezisebenza kanzima zivame ukukhiqizwa ngokukhipha okushisayo, futhi ukwakheka kwamashubhu ngokuvamile kucutshungulwa ngokugoqeka okubandayo. Lezi zinqubo zibonakala ngokunemba okuphezulu, ukuguquguquka okukhulu kwepulasitiki, kanye nezakhiwo ezinhle zesakhiwo samapayipi, ngakho-ke zisetshenziswa.
Imvamisa amapayipi ensimbi engagqwali anembile angu-301, insimbi engagqwali engu-304, insimbi engagqwali engu-316, insimbi engu-316L, insimbi engagqwali engu-310S. Ngokuvamile, kukhiqizwa izinto ezingaphezu kwe-NI8, okungukuthi, izinto ezingaphezulu kuka-304, futhi amashubhu anembile ensimbi engenasici anezinto eziphansi awakhiqizwa.
Kuwumkhuba ukubiza i-201 kanye ne-202 insimbi engagqwali, ngoba inozibuthe futhi iheha omazibuthe. I-301 nayo ayiyona i-magnetic, kodwa inguzibuthe ngemva kokusebenza okubandayo futhi iheha omazibuthe. Ama-304, 316 awawona amazibuthe, awakhangi kazibuthe, futhi awanamatheli kumazibuthe. Isizathu esiyinhloko sokuthi kukazibuthe noma cha ukuthi impahla yensimbi engagqwali iqukethe i-chromium, i-nickel nezinye izakhi ngezilinganiso ezahlukene kanye nezakhiwo ze-metallographic. Ukuhlanganisa lezi zici ezingenhla, futhi kuyindlela engenzeka yokusebenzisa odonsa ukuze bahlulele ikhwalithi yensimbi engagqwali, kodwa le ndlela ayiyona yesayensi, ngoba ekukhiqizeni insimbi engagqwali, kunomdwebo obandayo, umdwebo oshisayo, futhi kangcono ngemva- ukwelashwa, ngakho-ke i-magnetism incane noma ayikho. Uma kungalungile, i-magnetism izoba mkhulu, engakwazi ukukhombisa ubumsulwa bensimbi engagqwali. Abasebenzisi bangaphinda bahlulele ngokupakishwa nokubukeka kwamashubhu ensimbi engagqwali anembayo: ubuhwaqane, ukujiya okufanayo, nokuthi akhona yini amabala ngaphezulu.
Izinqubo ezilandelayo zokugingqa nokudweba zokucubungula amapayipi nazo zibaluleke kakhulu. Isibonelo, ukukhishwa kwamafutha kanye nama-oxide angaphezulu ku-extrusion akulungile, okuzophazamisa kakhulu ukunemba nekhwalithi yangaphezulu yamapayipi anemba ensimbi engagqwali.
