Ipayipi yensimbi
Incazelo emfushane:
Ipayipi lensimbi elicijile lisho ipayipi elibunjwe ngensimbi ekhonjiwe.Ipayipi le-cast iron lisetshenziselwa ukuphakelwa kwamanzi, amapayipi okukhipha amanzi kanye namapayipi okudlulisa igesi, okuhlanganisa amapayipi ensimbi aqondile nokufakwa kwamapayipi.Amandla okusebenza aphansi.Ngokwezindlela ezahlukene zokuphonsa, ihlukaniswe yaba ipayipi lensimbi eqhubekayo kanye nepayipi yensimbi eyi-centrifugal, phakathi kwayo ipayipi yensimbi eyi-centrifugal ihlukaniswe isikhunta sesihlabathi kanye nesikhunta sensimbi.Ngokwezinto ezahlukahlukene, ihlukaniswe yaba ipayipi lensimbi elimpunga kanye nepayipi lensimbi le-ductile.Ngokusho kwamafomu okuxhumana ahlukene, ihlukaniswe yaba isikhombimsebenzisi esivumelana nezimo, isikhombimsebenzisi se-flange, isikhombimsebenzisi sokuzibamba, isikhombimsebenzisi esiqinile, njll.

Ingqikithi yepayipi lensimbi eyi-ductile iron pipe, ebizwa ngokuthi lokhu ngoba inemvelo yensimbi nokusebenza kwensimbi.I-graphite ekwipayipi yensimbi eyi-ductile ikhona ngendlela eyindilinga, futhi ubukhulu begraphite ngokuvamile bungu-6-7.Ikhwalithi idinga ukuthi izinga le-spheroidization lepayipi lensimbi elibunjiwe lilawulwe liye ezingeni 1-3, futhi izinga le-spheroidization libe ngu-≥80%, ngakho izakhiwo zemishini yento ngokwayo zithuthukiswa kahle, ngesimo sensimbi nokusebenza kwensimbi. .Ngemuva kokufakwa kwe-annealing, ukwakheka kwe-metallographic yepayipi le-iron ductile i-ferrite kanye nenani elincane le-pearlite, kanye nezakhiwo zemishini zinhle, ngakho-ke ibizwa nangokuthi ipayipi lensimbi ekhonjiwe.
