I-DIN EN877 I-Cast Iron Pipes and Fittings, Isevisi Yomkhiqizo Wensimbi Yensimbi Empunga, Imboni Yoqobo yase-China

Insimbi eyinsimbi empunga isho insimbi ene-flake graphite, ebizwa nge-grey cast iron ngoba ukuphuka kubampunga okumnyama uma kuphukile. Izingxenye eziyinhloko yi-iron, i-carbon, i-silicon, i-manganese, isulfure, ne-phosphorus. Iyinsimbi esakazwa kakhulu esetshenziswa kakhulu futhi okukhiphayo kubala ngaphezu kuka-80% wesamba sensimbi ekhishwayo. Insimbi empunga inezinto ezinhle zokulingisa nokusika kanye nokumelana nokugqokwa okuhle. Isetshenziselwa ukwenza ama-racks, amakhabethe, njll. I-graphite yensimbi e-grey cast isesimweni sama-flakes, indawo yokuthwala ephumelelayo incane kakhulu, futhi ithiphu ye-graphite ijwayele ukugxila ekucindezelekeni, ngakho amandla, i-plasticity, nokuqina kokumpunga. insimbi eyinsimbi iphansi kunezinye izinsimbi ezisansimbi. Kodwa inokuncibilika okuhle kakhulu kokudlidliza, ukuzwela kwe-notch ephansi, nokumelana nokugqoka okuphezulu.

I-Grey cast iron inokuqukethwe kwekhabhoni ephezulu kakhulu (2.7% kuya ku-4.0%), engathathwa njenge-matrix ye-carbon steel plus flake graphite. Ngokwezinhlaka ezihlukene ze-matrix, insimbi empunga ihlukaniswe izigaba ezintathu: i-ferrite matrix grey cast iron; i-pearlite-ferrite matrix grey cast iron; i-pearlite matrix grey cast iron

Njengamanje, imikhiqizo yethu yensimbi empunga iwukufakwa kwamapayipi okudonsa amanzi ensimbi.
