Izindololwane zensimbi ye-Carbon ziyizinto zokufakwa kwamapayipi ensimbi ezishintsha isiqondiso samapayipi kumapayipi ensimbi ye-carbon.Izinto ezisetshenziswa izindololwane yinsimbi ephonswe, insimbi engagqwali, insimbi yengxubevange, insimbi egayiwe ethambile, insimbi ye-carbon, izinsimbi ezingezona ayoni namapulasitiki, njll.;Indololwane engu-45°, indololwane engu-90° kanye nendololwane engu-180° Izinhlobo ezintathu zezindololwane zivame kakhulu, kanti ezinye izindololwane ze-engeli ezingavamile ezifana no-60° nazo zifakiwe ngokuvumelana nezidingo zephrojekthi.Ngokwenqubo yokukhiqiza, ingahlukaniswa ibe: indololwane yokushisela, indololwane yokunyathela, i-push indololwane, indololwane yokuphonsa, njll. Sonke siyazi ukuthi lapho uklama futhi ukhiqiza izindololwane ze-carbon steel, izakhiwo zemishini ye-carbon steel elbows zidinga ukucatshangelwa.Ngakho, indlela yokuthuthukisa ubulukhuni carbon steel izindololwane?Sesikushilo lokho, kufanele sikhulume ngenqubo yokwelapha ukushisa.Ake sifunde mayelana nokwelashwa kokushisa kwezindololwane ze-carbon steel.
Okokuqala nje, kungani izindololwane ze-carbon steel zidinga ukwelashwa ngokushisa?Uma kuziwa ekuthuthukiseni izakhiwo zemishini, sonke siyazi: njengengxenye yesistimu yamapayipi, ubulukhuni bendololwane akufanele bube buphakeme kakhulu, ubulukhuni obukhulu kakhulu abuhambisani nokugcina amandla okuguqula, futhi kulula ukuphuka;i-plasticity ayinhle kakhulu, ngokusetshenziswa kwesikhathi.Ngokukhula kwe-, ukuguqulwa kwendololwane kuzoqina kancane kancane, kunciphisa ukuzinza kwesistimu yamapayipi.Ukwelashwa kokushisa kuyinqubo ekhona yokuthola amandla anele, ubulukhuni kanye nokuqina kwepulasitiki.

Futhi ukujwayelekile kungaxazulula le nkinga kahle kakhulu.I-normalizing yindlela yokwelapha ukushisa lapho indololwane ecindezelwe ngokushisa ishiselwa ngaphezu kwezinga lokushisa elibucayi bese ipholiswa emoyeni.Phakathi nale nqubo, isakhiwo se-martensite esingalingani sizoshintsha kancane kancane sibe isakhiwo se-austenite esifanayo.Kule nqubo, Icala le-brittleness kanye nokuqina - i-cementite e-reticulated iyanyamalala ngobuningi, okusanhlamvu okuqinile kuyacwengwa, ukuqina kanye ne-plasticity kulinganisa kahle, futhi izakhiwo zemishini ezibanzi ziyathuthukiswa.Ngakho-ke, ukonga kakhulu ukusebenzisa i-normalizing esikhundleni sokucisha izindololwane ezinezidingo eziphansi.
Nokho, lokhu okungenhla kuyisingeniso esifushane solwazi olufanele lokwelashwa kokushisa kwendololwane ye-carbon steel, ngiyabonga ngokufunda.
