Ingxubevange yensimbi ekhethekile:41Cr4,25CrMo4,30CrMo4,34CrMo4,42CrMo4

OD: 20-660mm WT: 2.3-100mm L: 5.8M, 6M, 11.8M, 12M nanoma yibuphi obunye ubude obucacisiwe.

Isicelo: Umshini, Ubunjiniyela obujwayelekile, ingalo ye-crane, Izihlahla, Amasilinda Ahlukahlukene, Ama-Conveyor Rolls, Ama-Hollow Shafts, Izingxenye Ezingenalutho kanye nezingxenye, Amantongomane, Izindandatho, njll.

Ukusetshenziswa kwepayipi elingenamthungo elingu-42CrMo: insimbi ekhethekile esetshenziselwa amabhuloho yi-“42CrMo”, insimbi ekhethekile yamagida ezimoto yi-“42CrMo”, kanti insimbi ekhethekile yemikhumbi yokucindezela ithi “42CrMo”.Lolu hlobo lwensimbi luthuthukisa izakhiwo zensimbi ngokulungisa okuqukethwe kwekhabhoni (c).Ngakho-ke, ngokusho kokuqukethwe kwekhabhoni, lolu hlobo lwensimbi lungahlukaniswa lube: insimbi ephansi ye-carbon - okuqukethwe kwekhabhoni ngokuvamile kungaphansi kuka-0.25%, njengensimbi engu-10 no-20;I-Medium carbon steel - okuqukethwe kwekhabhoni ngokuvamile kuphakathi kuka-0.25 no-0.60%, njengensimbi engama-35 no-45;I-high carbon steel - okuqukethwe kwekhabhoni ngokuvamile kungaphezu kuka-0.60%.Lolu hlobo lwensimbi ngokuvamile alusetshenziselwa ukwenza amapayipi ensimbi.

Uhlelo lokusebenza olujwayelekile
Ifanele ukwenza isikhunta sepulasitiki esikhulu nesiphakathi nendawo esidinga amandla athile nokuqina.
