Kev Poj Thoob Plaub Taub Qhwv Teeb Tseg:
Tsis yog. 45 tuab ntsa cov yeeb nkab hlua yeeb nkab yog me ntsis muaj zog tshaj li hlau No. 15, tsis tshua muaj quenched thiab tsis muaj kev ntxhov siab. Khaub thuas yas thiab ua rau khoov dov, dov, khoov thiab rau cov zauv zawg, cov hlua caj dab thiab kev sib txuas rau kev siv vuam welding zoo, thaum lub thickness yog me me, nws yuav tsum nruj kom nrawm nrawm los yog txoj kev zoo nkauj. Kev mob khaub thuas los yog lub cev tsis zoo ntawm kev txiav yog qhov zoo tshaj qhov kev sib ntxub. Nws yog feem ntau yog siv los ua cov khoom siv nrog me ntsis quab yuam thiab siab toughness.
45 # Cov Ncauj Loj Cov Ncauj Hnoos Ntau Cov Ntaub Ntawv Seamless:

Kev kho cua sov: tsis pub tsawg tshaj 156HB, qauv loj: qauv loj 25 hli. Kev tsim cov txheej txheem rau kev tsim ntawm txoj kev tsis muaj 45 lub qhov sib xyaw ua kom tsis muaj steel seamless yeeb nkab tau muab faib ua plaub hom kev yooj yim ntawm cov khoom siv txias, txias-dov, kub-rolled steel yeeb, thermal expansion, cov khoom yog 10 #, 20 #, 35 # , 45 # hu ua 16Mn ntawm qhov dog dig zoo tib yam steel, steel lossis hlau hlau yeeb nkab uas hu ua tsis tshua muaj hlau yeeb nkab yeeb nkab, steel yeeb nkab ua los ntawm 27SiMn, 12Cr1MoV 15CrMo, 35CrMo, 10CrMo910, thiab stainless hlau tube hu ua alloy steel yeeb nkab. Raws li daim ntawv thov muab faib ua qauv nrog seamless steel tub rau conveying; seamless hlau raj; seamless steel yeeb yeeb nkab seamless steel yeeb nkab nrog kev kub siab boiler; boiler; kev kub siab seamless steel yeeb nkab seamless steel yeeb nkab siv rau tshuaj chiv cov tshuaj; kev tshawb nrhav geologics; seamless steel yeeb nkab rau roj av kev tshawb nrhiav cib; seamless steel yeeb nkab seamless steel yeeb nkab siv rau roj av tawg; nkoj; txias dov precision seamless hlau hlab; ntau yam hlau alloy.
Tsis yog. 45 tuab ntsa duav seamless steel yeeb xa tuaj tsis muaj cua sov los yog kev kho cua sov (kub nyhiab, kub cev los yog kub kub npau npau). Cov khoom xa hluav taws xob yuav tsum tau muab sau rau hauv daim ntawv cog lus thiab xa thaum tsis muaj cua sov.
45 # Tuab phab ntsa seamless yeeb nkab Hnyav mis:
Cov ntsuas phaus npog ntawm No. 45 tuab ntsa ntawm lub qhov rooj [[txheej thawv] [wall thickness] * phab ntsa thickness] * 0.02466 = kg / metres (ib qhov hnyav nyhav)
