Seamless casing thiab ERW (hluav taws xob tiv thaiv welded) casing yog ob hom roj av casing. Seamless casing yog tus dab ua los ntawm seamless steel yeeb nkab. Seamless steel yeeb nkab yog hais txog cov kav dej hlau ua los ntawm plaub txoj kev: kub dov, txias dov, kev kos tshuaj txias, thiab kos duab kub. Cov yeeb nkab lub cev nws tus kheej tsis muaj welds. ERW casing yog ib tug casing ua los ntawm hluav taws xob welded yeeb nkab raws li cov khoom siv raw. ERW (steel yeeb nkab) yog hais txog txoj hlua khi ncaj Welded Welded yeeb nkab tsim los ntawm kev ua haujlwm siab tiv thaiv vuam txheej txheem vuam. Cov khoom siv raw steel phaj (kauj) ntawm ERW WELDED cov yeeb nkab yog tsawg cov hlau micro-alloy steel dov los ntawm tmcp (thermomechanical tswj cov txheej txheem). Niaj hnub no peb yuav piav feem ntau piav qhia hauv qab qhov sib txawv ntawm cov nplais uas muaj kev xav thiab erw casing.
1. Sab nraud txoj taub khiav dim
Seamless steel yeeb nkab: siv kub yob txoj kev tsim cov txheej txheem, sizing ua tiav nyob ib ncig ntawm 8000c. Tus raw cov khoom muaj pes tsawg leeg, cov cua txias thiab lub xeev txias ntawm lub taub muaj qhov loj me me kom yog thiab qhov kev hloov pauv yog qhov loj.
ERW steel yeeb nkab: cov khaub ncaws txias, nrog cov sizing txo qis ntawm {1}}. 6%. Cov txheej txheem ntsuas kub yog qhov tseem ceeb ntawm qhov kub thiab txias, yog li cov taub uas muaj tseeb yog qhov muaj txiaj ntsig me me, uas tau txais txiaj ntsig zoo rau kev tshem tawm cov tawv tawv dub;
2. Phab ntsa tuab tuab tiv thaiv
Seamless steel yeeb nkab: tsim los ntawm perforated round hlau, nrog loj phab ntsa thickness txawv. Tom ntej kub dov tawm tuaj yeem tshem tawm cov ntoo tsis sib xws, tab sis feem ntau cov kev ua tiav ntau dua tuaj yeem tswj nws hauv ± 5% t.
ERW steel yeeb nkab: kub-rolled coil yog siv los ua cov khoom siv raw, thiab cov niaj hnub no kub-kub thickness kam tau tswj tsis pub dhau {2}}. 05mm.
3. Tsos
Cov txheej txheem sab nraud tsis xws luag siv rau seamless steel kav tsis tuaj yeem raug tshem tawm los ntawm kev tsis xws luag muaj av tom qab cov khoom tiav tiav lawm; Cov kauv txoj kab laug tom qab pom kev zoo tag nrho tsuas yog qee qhov kev tshem tawm ib nrab thaum lub rooj txo phab ntsa.
Erw Steel kav siv kub-rolled coils raws li cov ntaub ntawv raw. Qhov saum npoo zoo ntawm lub kauj yog qhov zoo ntawm erw steel yeeb nkab. Qhov chaw nto kub ntawm cov coil kub yog yooj yim los tswj thiab ntawm kev ua tau zoo. Yog li no, qhov zoo ntawm erw steel kav yog zoo dua li seamless steel kav.
4. Ncaus
Seamless steel yeeb nkab: siv kub dov txoj kev txheej txheem. Tus raw cov khoom muaj pes tsawg leeg, cov xwm txheej txias thiab lub xeev txias ntawm cov yob ntawm cov yeeb nkab steel muaj lub zog loj ntawm nws cov taub. Yog li ntawd, kho tswj ntawm lub taub sab hauv yog qhov nyuaj thiab hloov kho ntau yog qhov loj.
ERW Steel Yeeb: Nws yog tsim los ntawm kev txias txias, yog li txoj kab uas hla rov qab yog tswj thiab qhov kev hloov pauv yog me me.
5. Tensile kuaj
Lub tensile kev ua tau ntsuas ntawm Seamless Steel Kav thiab cov qauv siv hlau, tab sis lub zog ntawm Seamless Steel kav yog feem ntau ntawm cov kev txwv sab sauv thiab cov yas yog nyob ntawm qhov kev txwv qis. Hauv kev sib piv, lub zog ntsuas ntawm ERW steel yeeb nkab yog nyob rau hauv lub xeev zoo tshaj plaws, thiab cov yas nplaum Index yog 33.3% siab dua tus qauv. Qhov laj thawj yog qhov ua tau zoo ntawm cov coils kub, cov khoom siv raw ntawm Erw Steel kav, tawm ntawm cov cua sov rauv, tawm ntawm cov cua txias thiab tswj tau cov dov; Seamless steel kav feem tsuas yog cia siab rau cov ntsiab lus carbon, uas ua rau nws nyuaj los xyuas kom muaj zog thiab muaj kuab yas. Tsim nyog sib xyaw.
6. Hardness
Cov khoom siv raw ntawm ERW steel yeeb nkab, kub-rolled coil, tau muaj kev ua kom paub tseeb tias lub sijhawm ua haujlwm ntawm txhua feem ntawm cov kauj.
7. Cov nplej loj
ERW Steel Yeeb Nkab-Kub-Rolled coil cov khoom siv ays, tsis muaj kab ke ntawm cov khoom sib xyaw ua ke dav thiab cov hws me, cov qauv me me sib cav thiab cov qauv sib cav; Nyob rau hauv cov txheej txheem dov tom ntej, tswj cov ntawv thov ntawm cov khaub thuas tov cov thev naus laus zis txuas ntxiv ua kom cov noob qoob loo loj.
8. Kev sim sib tsoo
ERW steel yeeb yog vim muaj cov yam ntxwv ntawm nws cov ntaub ntawv nyoos thiab cov yeeb nkab ua. Nws cov phab ntsa thickness uniformity thiab ovality tau zoo dua li cov neeg siv khoom lag luam tawm, uas yog vim li cas thiaj li vau yog siab dua li ntawm cov kav hlau Seamens.
9. Kev cuam tshuam kev ntsuas
Txij li qhov cuam tshuam nyuaj ntawm cov khoom siv hauv paus ntawm ERW steel kav yog ntau zaus uas cov neeg ncaj ntawm Weld yog tus yuam sij rau ERW steel kav hlau. Los ntawm kev tswj cov ncauj lus hauv cov ntaub ntawv raw, qhov ntsuas ntawm cov roj ntsha ua kom muaj qhov kub thiab txias, cov kev cuam tshuam rau cov roj weld Yog tias qhov tsim kho ntxiv, kev ua haujlwm vuam cuam tshuam tuaj yeem ze rau qhov chaw ntawm cov khoom siv, ua tiav kev ua tiav.
10. Kev kuaj
Kev kuaj kab mob tawg ntawm erw steel kav yog ntau dua li cov qauv ntawm phab ntsa tuab thiab niaj hnub sib txawv sab nraud ntawm erw steel kav hlau.
11. Ncaj nraim
Seamless steel kav yog tsim nyob rau hauv lub xeev yas, thiab nws nyuaj rau tswj hwm ntawm cov yeeb nkab ntawm cov yeeb nkab kawg nrog ib tus thawj coj (rolling txuas ntxiv yuav tsum tau 3 txog 4 tus kav);
Erdw steel kav dej yog cov neeg ua haujlwm txias-ua haujlwm steel kav uas yog ncaj hauv online hauv lub nroog hla kev. Tsis tas li ntawd, nws yog lub sijhawm tsis kawg, yog li ntawd txoj kev ncaj yog qhov zoo dua.
12. Kev noj hlau rau 10, 000 meters ntawm casing
ERW steel kav muaj cov ris tsho sib txawv ntawm phab ntsa tuab thiab negrigible phab ntsa thickness dogrees. Kev tswj hwm qhov tseeb txwv ntawm Seamless steel yeeb nkab phab ntsa thickness txawv yog ± 5% t, uas feem ntau tswj tau ntawm {% t. Txhawm rau kom ntseeg tau tias cov phab ntsa tuab tsawg kawg tuaj yeem ua kom tau raws cov qauv txheej txheem thiab kev ua tau zoo, tsuas yog daws tau phab ntsa tuab kom zoo. Yog li no ntawm cov xwm txheej zoo ib yam thiab qhov hnyav, erw steel kav dej yog}}} meter txheej txheem los ntawm {5}}%. Txawm nyob ntawm tus nqi ib yam, Erdw Casing zoo li cov neeg siv 5-10% ntawm kev yuav nqi.
Raws li cov chaw tsim khoom lag luam thiab cov khoom siv ntawm seamelless casing casing thiab ERW ua haujlwm tau tsim kho kom zoo dua qub, thiab tau txais qhov teeb meem zoo yog peb tus qauv. Tib lub sijhawm, raws li cov neeg siv khoom sib txawv, peb cov tswv yim tswj hwm cov txheej txheem kom ntseeg tau tias cov neeg yuav khoom tuaj yeem tswj cov txheej txheem thiab kev tsheb thauj khoom ntawm cov khoom. Nws tseem yog vim muaj cov txheej txheem tswj hwm phiaj xwm project uas vigor tsis tau muaj teeb meem nrog kev xa khoom ntawm nws cov khoom. Cov neeg ua haujlwm tswj hwm kev tiv thaiv prigons kuj tau txais daim ntawv pom zoo pom zoo los ntawm tus neeg siv khoom, thiab peb pab neeg tau zoo siab muaj cov npoj yaig zoo. Yog tias koj xav tau txais kev txhawb nqa los ntawm pab pawg muaj zog, thov mus ntsib nrog peb thiab peb yuav muab koj cov kev pabcuam zoo tshaj plaws.
