1. Cov kav dej seamless carbon steel puas tuaj yeem siv rau hauv qhov chaw siab - kub?
Yog lawm, seamless carbon steel kav yuav siv tau nyob rau hauv siab -kub ib puag ncig, tab sis qhov siv tau kub ntau yam txawv raws li cov khoom. Piv txwv li, zoo tib yam qis- carbon steel seamless kav (xws li 20#) tuaj yeem siv rau hauv ib puag ncig qis dua 450℃; nruab nrab carbon steel seamless kav yuav siv tau nyob rau hauv ib puag ncig hauv qab 500 degree; thiab siab- zoo carbon steel seamless kav (xws li 20G) tshwj xeeb uas siv rau boilers yuav siv tau nyob rau hauv siab - kub thiab siab - siab boiler ib puag ncig mus txog 540℃. Nws yuav tsum raug sau tseg tias thaum ua haujlwm kub siab tshaj qhov txwv, cov khoom yuav raug thermal deformation, uas yuav txo tau lub siab - bearing muaj peev xwm thiab kev pab cuam lub neej.
2. Puas yog seamless carbon steel kav corrosion-resistant?
Seamless carbon steel kav muaj qee yam corrosion kuj nyob rau hauv cov huab cua thiab nruab nrab dej ib puag ncig, tab sis lawv cov corrosion kuj tsis muaj zog nyob rau hauv acidic, alkaline, ntsev thiab lwm yam corrosive ib puag ncig. Txhawm rau txhim kho corrosion kuj, peb tuaj yeem ua cov kev kho saum npoo ntawm cov kav dej, xws li galvanizing (kub-dip galvanizing, electro-galvanizing), pleev xim, epoxy txheej, thiab lwm yam. Rau qhov hnyav corrosive, peb tuaj yeem pom zoo seamless alloy steel kav nrog zoo corrosion kuj raws li cov neeg siv khoom xav tau.
3. Dab tsi yog daim ntawv thov tseem ceeb ntawm seamless carbon steel kav hauv kev lag luam txawv teb chaws?
Seamless carbon steel kav muaj ntau yam kev siv hauv kev lag luam tawm txawv teb chaws, feem ntau suav nrog cov haujlwm hauv qab no: 1. Petroleum thiab natural gas kev lag luam: siv rau kev tshawb nrhiav roj thiab roj, kev thauj mus los thiab kev tsim cov kav dej; 2. Kev lag luam tshuaj: siv los thauj cov tshuaj lom neeg, xws li acids, alkalis, kuab tshuaj, thiab lwm yam; 3. Fais fab kev lag luam: siv rau boiler kav, chav kav hauv thermal fais fab nroj tsuag; 4. Kev tsim kho thiab kev tsim vaj tsev: siv rau kev tsim vaj tsev, cov kav dej thiab cov kav dej, cov kav dej cua sov; 5. Mechanical manufacturing: siv rau kev tsim khoom siv tshuab, hydraulic kheej kheej, bearings, thiab lwm yam .; 6. Automotive kev lag luam: siv rau kev tsim tsheb cov kav dej, tsav shafts, thiab lwm yam.
4. Koj cov kav dej seamless carbon steel ua tau li cas?
Peb seamless carbon steel kav nruj me ntsis ua raws li thoob ntiaj teb cov qauv tseem ceeb kom tau raws li cov kev xav tau ntawm ntau lub teb chaws thiab cheeb tsam. Cov qauv muaj xws li ASTM (American Society for Testing and Materials), API (American Petroleum Institute), DIN (German Industrial Standard), EN (European Standard), GB (Chinese National Standard), thiab lwm yam. Piv txwv li, ASTM A106 yog haum rau siab -kub thiab siab -5 roj kav dej, API D, roj thiab cov kav dej. 2448 yog tsim rau kev lag luam seamless kav, thiab EN 10210 yog tsim rau cov qauv seamless kav. Peb kuj tuaj yeem tsim cov kav dej raws li cov neeg siv khoom- cov qauv tshwj xeeb.
5. Koj ua li cas kuaj qhov zoo ntawm seamless carbon steel kav?
Peb muaj qhov ua tiav kev tshuaj xyuas zoo kom ntseeg tau tias txhua pawg ntawm seamless carbon steel kav ua tau raws li tus qauv yuav tsum tau ua. Cov khoom tseem ceeb ntawm kev soj ntsuam muaj xws li: 1. Tshuaj lom neeg muaj pes tsawg leeg tsom xam: kuaj xyuas cov ntsiab lus ntawm carbon, silicon, manganese, phosphorus, sulfur thiab lwm yam khoom kom ntseeg tau tias cov khoom tsim nyog; 2. Kev ntsuas kev ua tau zoo ntawm cov tshuab: suav nrog kev ntsuas tensile, ntsuas qhov ntsuas, ntsuas qhov cuam tshuam, ntsuas qhov nyuaj, txhawm rau txheeb xyuas lub zog thiab toughness ntawm cov yeeb nkab; 3. Tsis yog- kuaj kev puas tsuaj: suav nrog kev kuaj ultrasonic (UT), kuaj hluav taws xob (RT), kuaj cov hlau nplaum sib nqus (MT), txhawm rau txheeb xyuas qhov teeb meem sab hauv thiab qhov chaw ntawm cov yeeb nkab; 4. Dimensional soj ntsuam: xyuas cov kab sab nraud, puab txoj kab uas hla, phab ntsa thickness, ntev thiab ovality los xyuas kom meej qhov ntev; 5. Hydraulic siab test: kuaj lub siab- bearing peev thiab airtightness ntawm cov yeeb nkab.
