Hauv kev lag luam roj loj,Roj cov kav dej steel ua lub luag haujlwm tseem ceeb, ua lub luag haujlwm tseem ceeb hauv kev xa cov roj thiab cov roj av los ntawm kev rho tawm hauv av mus rau cov neeg siv kawg. Los ntawm kev ua haujlwm drilling hauv cov roj thiab roj mus rau kev thauj mus los ntawm cov kav dej ntev, ntau homRoj cov kav hlau, nrog lawv cov ntaub ntawv tshwj xeeb thiab cov khoom siv, xyuas kom muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm tag nrho kev lag luam saw. Kab lus no yuav tsom mus rau cov yeeb nkab carbon steel, seamless steel yeeb nkab, thiab API 5L steel yeeb nkab (steel yeeb nkab uas ua tau raws li API 5L cov qauv), suav nrog cov piv txwv xws li API 5L X70 yeeb nkab, API 5L X60 yeeb nkab, thiab API 5L X52 yeeb nkab, muab cov ncauj lus kom ntxaws txog cov ntaub ntawv, cov khoom, thiab ntau qhov ntau thiab tsawg.Roj cov kav hlau.
Kev txheeb xyuas cov khoom
Carbon steel yeeb nkab yog ib qho ntawm cov khoom siv feem ntau siv rauRoj cov kav hlau. Nws yog feem ntau tsim los ntawm hlau thiab carbon, nrog me me ntawm manganese, silicon, sulfur, thiab phosphorus. Cov ntsiab lus carbon txiav txim siab lub zog thiab toughness ntawm hlau. Feem ntau hais lus, cov ntsiab lus carbon ntau dua ua rau lub zog steel, tab sis toughness thiab weldability txo. Hauv kev lag luam roj, carbon steel yeeb nkab muaj kev ua tau zoo tag nrho. Nws tsis tsuas yog muaj lub zog siab los tiv thaiv kev kub ntxhov ntawm kev thauj mus los ntawm cov roj thiab roj, tab sis kuj muaj qee qhov nyuaj ntawm kev hloov mus rau qhov nyuaj geological ib puag ncig. Tsis tas li ntawd, cov pa roj carbon steel yeeb nkab yog tus nqi qis thiab muaj tus nqi siab, ua rau nws siv dav hauv cov roj thiab cov kav dej.
2. API 5L Hlau Yeeb Nkab Cov Khoom Siv
API 5L Steel Pipe yog tsim raws li API 5L tus qauv tsim los ntawm American Petroleum Institute (API) thiab feem ntau yog siv rau cov kav dej thiab roj. Cov yeeb nkab steel no tau muab faib ua ntau qib raws li cov hlau lub zog, xws li X52, X60, thiab X70. Piv txwv li, API 5L X52 Yeeb Nkab yog ua los ntawm high-strength low-alloy steel. Ntxiv nrog rau cov ntsiab lus tseem ceeb xws li carbon thiab hlau, nws tseem muaj cov ntsiab lus alloying xws li niobium, vanadium, thiab titanium. Qhov sib ntxiv ntawm cov alloying ntsiab no ho txhim khu cov hlau lub zog thiab toughness, thaum tseem txhim kho nws weldability thiab corrosion kuj. Cov khoom siv ntawm Api 5l X60 Pipe thiab Api 5l X70 Pipe yog qhov ua tau zoo ntxiv raws li lub hauv paus no. Los ntawm kev kho cov alloying piv piv thiab cov txheej txheem kev kho cua sov, cov hlau lub zog thiab tag nrho cov kev ua tau zoo yog ntxiv, ua kom nws ua tau raws li qhov xav tau ntawm kev thauj mus los ntawm cov roj thiab roj nyob rau hauv siab dua thiab kev ua haujlwm nyuaj.
Seamless steel yeeb nkab yog tsim los ntawm cov txheej txheem xws li perforation thiab yeeb nkab dov. Nws cov khoom tseem ceeb yog tib yam li cov lus hais txog cov pa roj carbon steel yeeb nkab thiab Api 5l series steel yeeb nkab, tab sis qhov tshwj xeeb ntawm nws cov txheej txheem ntau lawm muab nws qhov tshwj xeeb zoo. Seamless steel yeeb nkab tsis muaj welds ntawm nws phab ntsa, uas ua rau ib tug zoo tag nrho cov qauv thiab siab zog. Nws tuaj yeem tiv taus siab dua thiab hnyav dua ib puag ncig. Yog li ntawd, nws yog feem ntau siv hauv kev lag luam roj rau cov ntawv thov uas xav tau kev ua haujlwm siab, xws li cov roj hluav taws xob siab thiab cov kav dej thiab cov kav dej.
Khoom thiab yam ntxwv
1. Lub zog
Lub zog yog cov cuab yeej tseem ceeb ntawm cov kav dej, cuam tshuam ncaj qha rau lawv txoj kev nyab xeeb thaum thauj roj thiab roj. Lub zog qib ntawm API 5l series steel kav yog qhia los ntawm tus lej tom qab "X." Piv txwv li, X52 qhia qhov tsawg kawg nkaus lub zog ntawm 52 ksi (kilopounds ib square inch), sib npaug li ntawm 360 MPa hauv megapascals; X60 muaj qhov tsawg kawg nkaus tawm lub zog ntawm 60 ksi (kwv yees li 414 MPa); thiab X70 muaj qhov tsawg kawg nkaus lub zog ntawm 70 ksi (kwv yees li 483 MPa). Raws li qib zog nce, qhov siab ntawm cov yeeb nkab tuaj yeem tiv taus nce ntxiv, ua rau nws tsim nyog rau cov roj thiab cov kav dej nrog ntau qhov kev xav tau. Seamless steel yeeb nkab, vim nws cov qauv zoo ib yam thiab ruaj khov zog tis, ua tau zoo dua thaum muaj kev kub ntxhov.
2. Corrosion Resistance
Kev thauj roj thiab roj av tuaj yeem muaj cov xov xwm corrosive xws li hydrogen sulfide thiab carbon dioxide, yog li cov kav dej yuav tsum muaj qee qhov kev tiv thaiv corrosion. Carbon steel yeeb nkab inherently muaj qhov tsis muaj zog corrosion kuj, tab sis nws cov corrosion kuj tuaj yeem txhim kho tau zoo los ntawm kev ntxiv cov ntsiab lus alloying (xws li chromium thiab molybdenum hauv Api 5l series) thiab siv cov tshuaj tiv thaiv corrosion (xws li coatings thiab plating). Los ntawm cov khoom tsim nyog tsim thiab ua tiav, Api 5l X70 Pipe, X60 Pipe, thiab X52 Pipe, thiab lwm yam, tuav lub neej ntev kev pab cuam nyob rau hauv ib puag ncig corrosive.
3. Weldability
Thaum lub sij hawm siv roj pipeline, steel kav yuav tsum tau txuas nrog vuam, ua weldability yog ib qho tseem ceeb ntawm cov roj pipeline steel yeeb nkab. Api 5l series steel yeeb nkab yog tsim tshwj xeeb rau kev weldability zoo, ua kom lub zog thiab nruj ntawm cov pob qij txha. Cov welds zoo kuj tuaj yeem ua tiav nrog carbon steel yeeb nkab thiab seamless steel yeeb nkab siv cov txheej txheem vuam tsim nyog.
Qhov Loj
1. Sab nraud
Roj pipeline steel kav tuaj nyob rau hauv ib tug ntau yam ntawm sab nraud diameters kom tau raws li kev xav tau kev thauj mus los sib txawv. Cov kab dav dav dav dav rau Api 5L series steel kav muaj xws li 114.3mm (4 nti), 168.3mm (6.625 nti), 219.1mm (8.625 nti), 273.1mm (10.75 nti), 323.9mm (12.75 nti), 3565.6mm (12.75 nti), 3565.6mm 457.2mm (18 nti), 508mm (20 nti), 559mm (22 nti), thiab 610mm (24 nti). Qhov loj me ntawm txoj kab uas hla ntawm seamless steel kav yog zoo ib yam li cov Api 5L series, tab sis tsis yog-tus qauv qhov ntau thiab tsawg kuj tuaj yeem ua tau raws li cov neeg siv khoom xav tau.
2. Phab ntsa Thickness
Phab ntsa thickness yog qhov tseem ceeb cuam tshuam rau lub zog thiab lub peev xwm thauj khoom ntawm cov kav hlau. Phab ntsa thickness ntawm roj av steel kav nws txawv nyob ntawm seb lub siab ntsuas thiab daim ntawv thov yuav tsum tau. Siv API 5L X52 yeeb nkab ua piv txwv, rau ib txoj kab uas hla ntawm 114.3mm, cov phab ntsa tuab xws li 4.0mm, 4.5mm, thiab 5.0mm. Rau sab nraud txoj kab uas hla ntawm 219.1mm, phab ntsa thickness yuav yog 6.0mm, 7.0mm, los yog 8.0mm. API 5L X60 thiab X70 cov kav dej, vim lawv cov kev xav tau siab dua, feem ntau muaj cov phab ntsa tuab dua li X52 cov kav dej ntawm tib txoj kab uas hla los xyuas kom muaj zog txaus thiab kev nyab xeeb. Phab ntsa tuab ntawm seamless steel yeeb nkab tuaj yeem tswj tau raws li cov txheej txheem tsim khoom thiab cov neeg siv khoom, xws li 2 hli mus rau ntau kaum millimeters.
3. Ntev
Tus qauv ntev ntawm cov roj av steel yeeb nkab feem ntau yog 6 meters, 12 meters, thiab lwm yam, rau kev yooj yim ntawm kev thauj mus los thiab kev tsim kho. Hauv kev siv tiag tiag, kev cai ntev kuj tuaj yeem tsim raws li cov kev xav tau tshwj xeeb ntawm txoj haujlwm kav dej, txo qis ntawm qhov chaw txiav thiab vuam ua haujlwm thiab txhim kho kev tsim kho.
Hauv cov ntsiab lus, cov khoom siv, cov khoom siv, thiab cov pa loj loj ntawmRoj steel kav yog qhov tseem ceeb hauv lawv qhov kev tsim thiab kev siv. Carbon Steel Yeeb Nkab, Seamless Steel Yeeb Nkab, thiab cov kav hlau steel hauvApi 5l steel yeeb nkabseries, xws li X70, X60, thiab X52, txhua tus ua lub luag haujlwm tseem ceeb hauv ntau qhov chawRoj kev lag luam vim lawv qhov tshwj xeeb zoo. Nrog txoj kev loj hlob tsis tu ncua ntawm covRoj kev lag luam, kev ua tau zoo thiab kev xav tau zoo rauRoj cov yeeb nkab steel tau dhau los ua nruj heev. Nyob rau hauv lub neej yav tom ntej, kev ua haujlwm siab duaRoj steel kav yuav raug tsim thiab siv los ua kom tau raws li cov kev xav tau ntawm kev ua haujlwm nyuaj thiab kev thauj mus los ntev, kev kub ntxhov.
