isingeniso esifushane:
Ipayipi lensimbi engenamthungo liwumugqa omude wensimbi onengxenye engenalutho futhi awekho amalunga azungezile.Kuyipayipi lensimbi elikwazi ukumelana nemithombo yemali ebolayo ebuthakathaka njengomoya, isitimu, namanzi, kanye nemithombo yezindaba egqwala ngamakhemikhali njenge-asidi, i-alkali, nosawoti.Eyaziwa nangokuthi ipayipi lensimbi elimelana ne-asidi.
Insimbi engagqwali izici zamashubhu angenamthungo:
Okokuqala, ukushuba kodonga lwepayipi elingenamthungo lensimbi engagqwali, liyonga kakhulu futhi liyasebenziseka, futhi ukuqina kodonga kuba mncane, kuba nkulu izindleko zokucubungula;okwesibili, ubuchwepheshe bomkhiqizo bunquma ukulinganiselwa kwawo Ngokuvamile, ukunemba kwamapayipi ensimbi angenamthungo kuphansi: ukushuba okungalingani kodonga, ukukhanya okuphansi ngaphakathi nangaphandle kwepayipi, izindleko eziphezulu zokulinganisa, futhi kunemigodi namachashaza amnyama ngaphakathi nangaphandle okungelula ukukususa;ekugcineni, ukuhlolwa nokubunjwa kwayo kufanele kucutshungulwe ungaxhunyiwe ku-inthanethi.Ngakho-ke, ikhombisa ukuphakama kwayo ngokuya ngengcindezi ephezulu, amandla aphezulu, nezinto zokwakha zemishini.
Insimbi engagqwali izicelo zepayipi nekhono:
amapayipi ensimbi engenamthungo alula ngesisindo uma ukugoba namandla okugoqa kuyafana, ngakho asetshenziswa kabanzi ekwenzeni izingxenye zemishini nezakhiwo zobunjiniyela.Ibuye isetshenziselwe ukukhiqiza izikhali ezihlukahlukene ezivamile, imiphongolo, amagobolondo, njll. Amapayipi ensimbi engagqwali aphephile, anokwethenjelwa, ahlanzekile, anobungani bemvelo, ayonga futhi ayasebenza.Amapayipi anezindonga ezincane kanye nokuthuthukiswa okuphumelelayo kwezindlela ezintsha zokuxhuma ezinokwethenjelwa, ezilula futhi ezilula zibenza babe nezinzuzo ezingenakuqhathaniswa kwamanye amapayipi, futhi izicelo zabo kwezobunjiniyela zizoba ngaphezulu nangaphezulu., ukusetshenziswa kuzokwanda futhi kudume, futhi amathemba ayathembisa.
Ukumelana nokugqwala kwamapayipi ensimbi engenamthungo kuncike ezintweni ze-alloying eziqukethwe ensimbi.I-Chromium iyingxenye eyisisekelo yensimbi engagqwali ukuze ithole ukumelana nokugqwala.Uma okuqukethwe kwe-chromium kunsimbi kufinyelela cishe ku-12%, i-chromium nomoya-mpilo ku-corrosion medium act kwakheka ifilimu elincanyana le-oxide (ifilimu elizihambelayo) phezu kwensimbi., okungavimbela ukugqwala okuqhubekayo kwe-matrix yensimbi.Ngaphezu kwe-chromium, izakhi ze-alloying ezivame ukusetshenziswa zamapayipi ensimbi engenamthungo yi-nickel, i-molybdenum, i-titanium, i-niobium, ithusi, i-nitrogen, njll., ukuhlangabezana nezidingo zokusetshenziswa okuhlukahlukene kwesakhiwo nezakhiwo zensimbi engagqwali.
