1. Dab tsi yog qhov kam rau ntawm seamless carbon steel kav?
Kev ua siab ntev ntawm seamless carbon steel kav yog nruj me ntsis raws li cov qauv thoob ntiaj teb. Rau txoj kab uas hla sab nraud kam rau ua: rau cov kav dej nrog txoj kab uas hla sab nraud Tsawg dua lossis sib npaug ntawm 100mm, qhov kam rau ua yog ± 0.5mm; rau cov kav dej nrog txoj kab uas hla sab nraud> 100mm, qhov kam rau ua yog ± 0.8% ntawm cov kab sab nraud. Rau phab ntsa thickness kam rau ua: rau cov kav dej nrog phab ntsa thickness Tsawg dua los yog sib npaug rau 10 hli, qhov kam rau ua yog ± 10% ntawm phab ntsa thickness; rau cov kav dej nrog phab ntsa thickness> 10mm, qhov kam rau ua yog ± 8% ntawm phab ntsa thickness. Qhov ntev kam rau ua yog ± 5mm ib 'meter'. Peb kuj tuaj yeem kho qhov kam rau ua raws li cov neeg siv khoom tshwj xeeb kom tau raws li qhov xav tau ntawm cov ntawv thov sib txawv.
2. Puas seamless carbon steel kav xav tau kev kho cua sov?
Txawm hais tias seamless carbon steel kav xav tau kev kho cua sov yog nyob ntawm cov khoom siv thiab cov ntawv thov. Cov kev kho cua sov feem ntau muaj xws li annealing, normalizing, quenching thiab tempering. Piv txwv li: 1. Tsawg carbon steel seamless kav (xws li 20 #) feem ntau tsis xav tau kev kho cua sov, thiab tuaj yeem siv ncaj qha tom qab dov; 2. Nruab nrab thiab siab carbon steel seamless kav yuav tsum tau kho annealing kom txo hardness, txhim kho plasticity thiab toughness, thiab pab txhawb kev ua tom qab; 3. Seamless kav siv nyob rau hauv siab - kub thiab siab - ib puag ncig siab (xws li boiler kav) yuav tsum tau quenching thiab tempering kev kho mob los txhim kho lub zog thiab siab - kub kuj. Peb yuav ua raws li kev kho cua sov raws li cov khoom siv thiab cov neeg siv khoom xav tau.
3. Dab tsi yog qhov ceev ntawm seamless carbon steel kav?
Qhov ceev ntawm seamless carbon steel kav feem ntau yog 7.85g / cm³, uas yog tib yam li cov pa roj carbon zoo tib yam. The density is a fixed physical property of carbon steel, which is not affected by the specification (outer diameter, wall thickness) and processing method (hot rolling, cold drawing) of the pipe. Tus nqi ntom ntom no tuaj yeem siv los xam qhov hnyav ntawm cov yeeb nkab: qhov hnyav (kg)=(sab nraud txoj kab uas hla - phab ntsa thickness) × phab ntsa thickness × 0.02466 × ntev (meter). Peb tuaj yeem muab cov cuab yeej ntsuas qhov hnyav tshaj plaws rau cov neeg siv khoom kom ntsuas qhov hnyav ntawm cov kav dej uas xav tau.
4. Cov kav dej seamless carbon steel puas tuaj yeem siv rau kev thauj dej haus?
Yog lawm, seamless carbon steel kav siv tau rau kev thauj mus los ntawm dej haus, tab sis cov khoom noj sib xws - qib yuav tsum tau kho. Vim tias cov kav dej seamless carbon steel zoo tib yam tuaj yeem xeb hauv dej, thiab xeb yuav cuam tshuam rau cov dej haus zoo. Peb tuaj yeem nqa cov khoom noj-qib tiv thaiv-kev kho xeb (xws li zaub mov- qib epoxy txheej, npib tsib xee plating) rau ntawm cov yeeb nkab sab hauv kom ntseeg tau tias cov yeeb nkab tsis tso cov khoom tsis zoo thiab ua tau raws li cov qauv kev nyab xeeb ntawm ntau lub teb chaws. Ua ntej siv, nws tseem yuav tsum tau ntxuav cov yeeb nkab kom tshem tawm cov impurities thiab xeb sab hauv.
5. Daim ntawv pov thawj dab tsi koj tuaj yeem muab rau seamless carbon steel kav?
Peb tuaj yeem muab cov ntawv pov thawj tiav los xyuas kom meej tias seamless carbon steel kav ua tau raws li cov kev cai ntshuam ntawm cov neeg siv khoom lub teb chaws lossis cheeb tsam. Cov ntawv pov thawj muaj xws li: 1. Daim Ntawv Pov Thawj Zoo (QC Certificate): ua pov thawj qhov zoo ntawm cov yeeb nkab ua tau raws li tus qauv yuav tsum tau ua; 2. Chemical Composition Report thiab Mechanical Performance Report: Cov ntaub ntawv ntxaws ntxaws ntawm cov yeeb nkab; 3. Tsis yog-Daim Ntawv Tshaj Tawm Kev Ntsuas Kev Ua Phem: Kev sim cov txiaj ntsig ntawm ultrasonic, radiographic thiab lwm yam kev sim; 4. ISO 9001 Quality Management System Certificate: ua pov thawj peb cov kev tsim khoom thiab kev tswj xyuas zoo raws li cov qauv thoob ntiaj teb; 5. Daim ntawv tshaj tawm kev lis kev cai, Kev Lag Luam Kev Lag Luam, Daim Ntawv Teev Npe: cov ntaub ntawv tsim nyog rau kev xa tawm; 6. Cov ntawv pov thawj tshwj xeeb: xws li daim ntawv pov thawj CE (rau European lag luam), API daim ntawv pov thawj (rau kev lag luam roj thiab roj), thiab lwm yam. Peb tuaj yeem muab cov ntawv pov thawj sib xws raws li tus neeg siv khoom xav tau.
