Isigqubuthelo somngxuma wentsimbi sahlulahlulwe saba sisigqubuthelo somngxuma wentsimbi kunye nezigqubuthelo zomngxuma wentsimbi ezingwevu, xa sithetha ngokubanzi, ubunzima obufanayo bezigqubuthelo zomngxuma wentsimbi kunezigqubuthelo zentsimbi engwevu.Izinto ezisetyenziselwa ukugquma umngxuma wentsimbi engwevu ngokuqhelekileyo yi-HT200, kwaye imathiriyeli esetyenziselwa ukugquma umngxuma we-inki ye-inki etyhutyhayo ngokubanzi yi-QT500-7.

Iimpawu zesigqubuthelo somngxuma we-inki espheroidal:

Ukuqina okuhle.Ixabiso lempembelelo lifana nelo lentsimbi ye-carbon ephakathi kunye namaxesha angaphezu kwe-10 yentsimbi engwevu.

Ukuxhathisa okuqinileyo kwe-corrosion.Uvavanyo lokutya kokutshiza kwamanzi, iintsuku ezingama-90 zomhlwa ngumbhobho wentsimbi we-1/40 kuphela, yi-1/10 yombhobho wentsimbi engwevu.Ubomi benkonzo ngama-2 amaxesha e-grey iron pipe kunye namaxesha ama-5 kumbhobho wensimbi oqhelekileyo.

Iplastiki enhle.Elongation≥I-7%, efana ne-carbon steel material ephezulu, ngelixa i-grey iron elongation yi-zero.

Amandla aphezulu.Amandla okuqina ob≥420MPa, isivuno amandla os≥I-300MPa, kunye nentsimbi ye-carbon ephantsi iyafana, ngamaxesha amathathu ezinto zentsimbi ezingwevu.

Isicelo: indlela kamasipala, uhola wendlela, unxibelelwano, amandla, itephu yamanzi, uluntu, isikolo kunye nezinye iipaki.
