Ubuchwepheshe bokucubungula nokwakha amapayipi okunemba kwensimbi engagqwali asebenza kahle kakhulu buhlukile kumapayipi angenamthungo endabuko. Izimbobo zepayipi ezingenamthungo zendabuko ngokuvamile zikhiqizwa ukubhoboza okushisayo okugoqeka okunemiphetho emibili, futhi inqubo yokwakha amapayipi ngokuvamile isebenzisa inqubo yokwakha ukudweba. Amapayipi okunemba kwensimbi engagqwali ngokuvamile asetshenziswa ezinsimbini zokunemba noma kumadivayisi ezokwelapha. Amanani awaphezulu nje kuphela, kodwa futhi avame ukusetshenziswa emishinini nasezintweni ezibalulekile. Ngakho-ke, izidingo zezinto zokwakha, ukunemba kanye nokuphela kwendawo yamapayipi ensimbi engagqwali okunemba ziphakeme kakhulu.
Izimbobo zamapayipi zezinto zokwakha ezisebenza kahle kakhulu ezilukhuni ukwakheka ngokuvamile zikhiqizwa yi-hot extrusion, kanti ukwakheka kwamapayipi ngokuvamile kucutshungulwa ngokugoqa okubandayo. Lezi zinqubo zibonakala ngokunemba okuphezulu, ukuguqulwa kwepulasitiki enkulu, kanye nezakhiwo ezinhle zesakhiwo samapayipi, ngakho-ke ziyasetshenziswa.
Ngokuvamile amapayipi ensimbi engagqwali aqondile ayinsimbi engagqwali engu-301, insimbi engagqwali engu-304, insimbi engagqwali engu-316, insimbi engagqwali engu-316L, insimbi engagqwali engu-310S. Ngokuvamile, kukhiqizwa izinto ezingaphezu kwe-NI8, okungukuthi, izinto ezingaphezu kuka-304, kanti amapayipi okunemba ensimbi engagqwali anezinto eziphansi awakhiqizwa.
Kujwayelekile ukubiza insimbi engagqwali engu-201 kanye ne-202, ngoba inamandla kazibuthe futhi inamandla okudonsa omazibuthe. I-301 nayo ayinamandla kazibuthe, kodwa inamandla kazibuthe ngemva kokusebenza okubandayo futhi inamandla okudonsa omazibuthe. I-304, i-316 ayinamandla kazibuthe, ayinawo amandla okudonsa omazibuthe, futhi ayinamatheli omazibuthe. Isizathu esiyinhloko sokuthi inamandla kazibuthe noma cha ukuthi izinto zensimbi engagqwali ziqukethe i-chromium, i-nickel nezinye izinto ngezilinganiso ezahlukene kanye nezakhiwo ze-metallographic. Uma kuhlanganiswa izici ezingenhla, kuyindlela engenzeka yokusebenzisa omazibuthe ukwahlulela ikhwalithi yensimbi engagqwali, kodwa le ndlela ayiyona isayensi, ngoba enqubweni yokukhiqiza insimbi engagqwali, kukhona ukudweba okubandayo, ukudweba okushisayo, kanye nokwelashwa okungcono ngemva kokwelashwa, ngakho amandla kazibuthe aphansi noma cha. Uma engalungile, amandla kazibuthe azoba makhulu, angeke abonise ubumsulwa bensimbi engagqwali. Abasebenzisi bangahlulela futhi ngokupakishwa kanye nokubukeka kwamashubhu ensimbi engagqwali anembile: ubulukhuni, ukujiya okufanayo, nokuthi ngabe kukhona amabala ebusweni.
Izinqubo ezilandelayo zokugoqa nokudweba zokucubungula amapayipi nazo zibaluleke kakhulu. Isibonelo, ukususwa kwezinto zokugcoba kanye nama-surface oxides ekukhishweni akulungile, okuzothinta kakhulu ukunemba kanye nekhwalithi yobuso bamapayipi okunemba ensimbi engagqwali.
