Ulwazi oluyisisekelo lwezinto zensimbi (1)

Insimbi yengulube nensimbi sekuhlangene kubizwa ngokuthi izinsimbi ezisansimbi.I-ayoni iyingxenye yayo eyinhloko futhi iqukethe inani elithile lekhabhoni nezinye izakhi zokulandelela.Ama-alloys anokuqukethwe kwekhabhoni ngaphansi kuka-2.11% (ubuningi) abizwa ngensimbi, futhi ama-alloys anokuqukethwe kwekhabhoni okukhulu noma okulingana no-2.11% (ubuningi) abizwa nge-iron yengulube.

I-iron yengulube ingahlukaniswa ibe yinsimbi yengulube yokwenza insimbi (eyaziwa nangokuthi insimbi emhlophe) kanye nensimbi yengulube yokuphonsa.

I-cast iron ibizwa nge-cast iron.Ngokwezici zokuma kwe-graphite, insimbi ekhonjiwe ingahlukaniswa ngezigaba ezilandelayo: insimbi empunga, i-codenamed HT;i-ductile cast iron, i-codenamed QT;insimbi engagqwali engagqwali;ezinye izinsimbi ezisansimbi, ezifana nensimbi engangeni ekushiseni nensimbi ethambile ethambile, insimbi esansimbi eMalleable ibizwa ngekhodi-KT, eyaziwa nangokuthi insimbi ethambileyo.

Amapayipi nokufakwa komfutho wensimbi akusakhiqizwa ngobuningi e-United States nakwamanye amazwe, kodwa kungase kukhiqizwe ngobuningi kwamanye amazwe.Amapayipi omfutho wensimbi athathe indawo yamapayipi omfutho wensimbi.Ukucaciswa okujwayelekile okuhambisanayo kuhlanganisa: ASME B16.3, ASME B16.4, ASME B16.12, ASME B16.42, ASMEB16.42, ASTM A74, ASTM A126, AWWA C110, AWWA C111, AWWA C150, AWWA C153, njll.

Insimbi empeleni iyingxubevange.Ingxenye eyinhloko insimbi kanye nenani elincane lekhabhoni.Futhi iqukethe izakhi zokulandelela ezifana ne-silicon, i-manganese, i-phosphorus, isulfure, i-chromium, i-nickel, i-molybdenum, i-tungsten ne-vanadium.Ukuhlukaniswa kwensimbi kuboniswa esithombeni
