Umkhiqizi Ohamba phambili we-ASTM 4140 42CrMo4 42CrMo Umkhiqizo Wepayipi Lepayipi Le-Hot Rolled Seamless Steel Tube
Incazelo emfushane:
Mayelana namazinga aqinile, sikholwa ukuthi uzosesha kude nakude nanoma yini engasehlula.Singasho kalula nje ngokuqiniseka okuphelele ukuthi ngekhwalithi enhle ngalezi zindleko singabaphansi kakhulu kumkhiqizi Oholayo we-ASTM 4140 42CrMo4 42CrMo Hot Rolled Alloy Seamless Steel Tube Pipe Product, Enkampanini yethu enekhwalithi ephezulu ukuqala ngayo njengesiqubulo sethu, senza imikhiqizo eyenziwe ngokuphelele e-Japan, kusukela ekuthengeni izinto zokwakha kuya ekucutshungulweni.Lokhu kubenza bakwazi ukuzisebenzisa ngokuthula kwengqondo.
Mayelana namazinga aqinile, sikholwa ukuthi uzosesha kude nakude nanoma yini engasehlula.Singasho kalula ngokuqiniseka okuphelele ukuthi ngekhwalithi enhle kangaka ngamanani anjalo singabantu abaphansi kakhuluChina 42CrMo4 Ingxubevange Ipayipi Seamless Steel, Phakathi neminyaka engu-11, Sibambe iqhaza emibukisweni engaphezu kuka-20, sithola ukunconywa okuphezulu kakhulu kukhasimende ngalinye.Inkampani yethu ibisebenzisa lelo “khasimende kuqala” futhi izibophezele ekusizeni amakhasimende ukuthi andise amabhizinisi awo, ukuze abe yi-Big Boss!
Ayinakho ukuthukuthela okusobala, ukuwohloka okuncane ngesikhathi sokucisha, umkhawulo wokukhathala okuphezulu kanye nokumelana nomthelela omningi ngemva kokwelashwa kokucisha nokushisa.Ipayipi elingenamthungo le-42CrMo linomthelela omuhle emazingeni okushisa aphansi namandla aphezulu okukhasa kanye namandla okubekezela ezingeni lokushisa eliphezulu.Ukucisha ubuso ngemva kokucisha nokubandisa kuvame ukusetshenziswa njengesikimu sokwelapha ukushisa kwamapayipi angenamthungo angu-42CrMo.
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.
