Kev siv cov hlau sib txawv raws li kev siv tiag tiag thiab kev ua haujlwm sib txawv rau cov lus teb sib txawv rau me me steel yeeb nkab loj kam rau ua, nto zoo, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, cov txheej txheem kev ua haujlwm, thiab lwm yam khoom tshwj xeeb xws li, cov txheej txheem sib txawv.

General seamless steel raj rau conveying dej, roj, roj pipelines thiab tsim cov kua dej structural Cheebtsam, cov lus teb rau nws mechanical zog xws li tensile zog, yield zog thiab elongation rau cov qauv kuaj.Cov kav dej feem ntau ua haujlwm nyob rau hauv cov xwm txheej ntawm lub siab, tseem hu ua kev sim siab ua tiav thiab flaring, squash, curling thiab lwm yam kev ntsuas kev ua haujlwm.Rau cov roj av loj-ntev ntev-ntev, cov roj ua kom zoo, cov raj xa hluav taws xob nrog cov yeeb nkab yog ua kom cov pa roj carbon sib npaug, vuam kev ua tau zoo, tsis tshua muaj kub toughness, kev nyuaj siab corrosion nyob rau hauv hnyav tej yam kev mob, corrosion, corrosion qaug zog zog thiab corrosion ib puag ncig thiab lwm yam. kev xav tau.Ordinary boiler raj siv nyob rau hauv kev tsim cov qauv steel yeeb nkab thiab superheated chav boilers boiling dej kav.High-pressure boiler raj rau kev kub siab los yog kub siab superheated chav boilers, cua kub exchangers thiab kav rau cov khoom siv siab.

Cov khoom siv thermal steel nyob rau hauv cov xwm txheej sib txawv ntawm qhov kub thiab txias ntawm kev ua haujlwm, yuav tsum xyuas kom meej qhov zoo ntawm qhov chaw, txhua yam thiab cov khoom siv thev naus laus zis.Feem ntau los kuaj nws cov khoom siv kho tshuab, flattening, thiab kev sim hydrostatic los ua, cov raj kub siab boiler kuj tau hais kom ua qhov kev sim thiab cov nplej loj ntawm cov kev sim tsis muaj kev puas tsuaj ntau dua.Mechanical seamless steel yeeb nkab raws li daim ntawv thov yuav tsum muaj qhov siab dua qhov tseeb, cov khoom siv kho tshuab zoo thiab qhov chaw.Cov kev cai tswj hwm xws li kev coj tus kheej hnav tsis kam, homogeneous, thiab nruj me ntsis hauv txoj kab uas hla kam rau ua.Ntxiv nrog rau kev ua cov khoom ntsuas kev ua haujlwm dav dav, peb yuav tsum ua kom pom qhov qis, tawg, annealing (pob ntawm lub koom haum, mesh teeb, strip), non-metallic inclusions (oxides, sulfides, dot, thiab lwm yam), de- ntsuas cov pa roj carbon txheej thiab nws cov hardness kuaj.Kev lag luam chiv feem ntau siv siab seamless steel siab ntawm 2200 ~ 3200Mpa, ua haujlwm kub -40℃~ 400℃thiab corrosive ib puag ncig, thauj tshuaj nruab nrab (xws li ammonia, methanol, urea, thiab lwm yam).Fertilizer kev lag luam nrog high-pressure seamless steel yeeb nkab yuav tsum muaj zog corrosion kuj, zoo mechanical zog thiab deg mob.Ntxiv nrog rau kev ua cov khoom siv kho tshuab, flattening, thiab kev sim hydrostatic, nws yuav tsum tau ua raws li ntau hom steel corrosion test streamlined raws li, cov thawj coj thiab ntau qhov kev ntsuam xyuas tsis muaj kev puas tsuaj.Petroleum, geological drilling yeeb nkab ntawm kev kub siab, alternating kev ntxhov siab, corrosive, hnyav ib puag ncig, nws yuav tsum yog qib siab siv, thiab hnav, torsion thiab corrosion-resistant zog.Raws li cov qib sib txawv ntawm cov hlau yuav tsum tau ua lub zog tensile, tawm lub zog, elongation, cuam tshuam toughness thiab hardness xeem.Siv rau cov roj zoo casing, tubing thiab laum yeeb nkab, yog cov ncauj lus kom ntxaws ntawm cov qib, qeb, thiab rau qhov sib txawv ntawm ib puag ncig, geological tej yam kev mob xaiv los ntawm tus neeg siv cov kev xav tau ntxiv rau cov kev xav tau siab, kom tau raws li cov kev xav tau tshwj xeeb.Tshuaj lom neeg, roj av cracking, aviation thiab lwm yam machinery kev lag luam nrog ntau yam acid-resistant stainless hlau yeeb nkab thiab txhua yam khoom dua li ua qhov kev sim siab, tab sis kuj tshwj xeeb rau kev ntsuam xyuas intergranular corrosion, flattening, flaring thiab non-destructive testing thiab lwm yam kev ntsuam xyuas.
