API5L X52 PSL1 SSAW COV YEEB

Lub ntsiab lus:Qhov no yog tus qauv kev cai lij choj qauv los ntawm Asmeskas Petroleum lub koom haum, thiab nws lub npe tag nrho yog "raj xa khoom txheem steel xaim kev tshwj xeeb".

Cov Hom Phiaj Tseem Ceeb: Tus qauv no qhia meej txog kev tsim khoom, cov ntaub ntawv xav tau, kev sim siab, thiab lwm yam kev lag luam thiab kev sib tw ntawm cov roj ntsha thiab roj av.

Tseem ceeb:API 5L yog qhov tseem ceeb, kev cai lij choj hauv cov roj thiab roj kev ruaj ntseg, kom muaj kev cia siab, kom muaj kev ntseeg siab nyob rau hauv high- deb tsheb thauj mus los. Nws tau siv dav dav thiab thov thoob ntiaj teb.

Lub ntsiab: Qhov no yog cov khoom siv qib cim ntawm cov yeeb nkab steel. Cov ntawv no sib raug rau qhov tsawg kawg nkaus tau lees lub zog (smys) ntawm cov raj xa dej hlau.

Tus nqi tshwj xeeb:X52 qhia tau tias yam tsawg kawg nkaus muaj zog ntawm cov qauv hlau ntawm chav tsev nyob rau ib square inch (psi), sib npaug rau 360 megapascals (mpa).

Tseem Ceeb:

Yield zog (YS): ntau dua lossis sib npaug zos rau 52,000 psi (360 MPa)- lub peev xwm tiv taus kev tawm tsam tas mus li

Lub zog tensile (TS): ntau dua lossis sib npaug zos rau 66,000 psi (455 mpa) {} lub peev xwm tiv thaiv tensile tsis ua hauj lwm

Kev Txom Nyem: Ua raws li cov qauv yuav tsum tau ua, nws ua kom qee qhov muaj peev xwm txawv.

Tshuaj lom neeg cov tshuaj:Muaj cov cai txwv ntawm cov ntsiab lus ntawm cov ntsiab lus ntawm cov ntsiab lus xws li cov pa roj carbon, mangelor, thiab silicon kom paub meej tias cov weldability, thiab corrosion tsis kam ntawm cov khoom. X52 feem ntau yog ib tus hlau microalloy thiab tej zaum yuav xav tau kev sib ntxiv ntawm cov khoom me me (xws li NB, V, los txhim kho nws lub zog.

Carbon sib npaug (CE / Cet):API 5L muaj cov txheej txheem kev suav thiab txwv yuav tsum rau cov pa roj carbon sib npaug uas muaj qhov cuam tshuam rau Weldability (cov cai rau PSL1 ntau dua li cov neeg rau PSL2).

• Lub ntsiab: Theem Khoom Tshwj Xeeb Qib 1.
• Muab:Qhov no yog qhov yooj yim - qib yuav tsum tau sau tseg hauv API 5L txheem.

• Nta ntawm PSL1: Cov kev xav tau rau tshuaj lom neeg muaj kev sib xyaw ua ke yog nyob rau hauv: qhov txwv sab saud uas muaj kev txwv tsis pub cov neeg yos tau zoo; Qhov yuav tsum muaj rau cov pa roj carbon monoxony yog tsawg.

• Cov cuab yeej yuav tsum tau ua ke yog qhov yooj yim:Feem ntau yog kom ua kom ntseeg tau lub zog muaj zog, lub zog tensile thiab elongation.

• Kev Cuam Tshuam Tougness (Charpy V - tsis tau) yuav tsum:Feem ntau, tsis muaj ib qho yuav tsum tau ua, tshwj tsis yog muaj tshwj xeeb los ntawm tus neeg yuav khoom hauv kev txiav txim. Nov yog ib qho ntawm cov tseem ceeb sib txawv ntawm PSL1 thiab PSL2.

• Kev kuaj Hardness Yuav Tsum:Feem ntau, tsis muaj qhov yuav tsum tau ua.

• Tsis - Kev sim tshuaj (ndt):Rau SSAW welded kav dej, txawm tias ultrasonic kuaj (it) lossis txuas ntxiv mus kuaj (li) yuav tsum muaj qhov zoo ntawm Weld Seam. Lub cev tag nrho cov yeeb nkab ut tsis yog qhov yuav tsum tau ua.

• HYDRAULIC TEST:Txhua cov yeeb nkab steel yuav tsum yauv mus kuaj hydraulic.

• Daim Ntawv Thov Qhia:Nws yog qhov tsim nyog rau tsis - qhov kev ntxhov siab ntawm lub xov tooj cua, thiab tsis muaj kev ntxhov siab rau qhov twg tsis muaj siab. Tus nqi feem ntau yog qis dua li ntawm PSL2.

• Lub ntsiab lus: Muab kauv submerged arc vuam.

• Txheej txheem tsim khoom:

Kub - rolled steel coils (daim hlau) uas ua tau raws li cov khoom siv raw thiab cov leeg sib txuas ua ke ntawm lub tshuab tsim.

Cov kauv pob qij txha ntawm lub raj yog welded ob qho tib si sab hauv thiab sab nraud nyob rau hauv lub submerged arc vuam lub xeev. Txheej txheem vuam yuav siv rau hauv qab txheej flux, nrog arc invisible. Lub flux muab kev tiv thaiv thiab sib tw metallurgical.

• Cov yam ntxwv (piv nrog lwm cov kev vuam kev xws li LSAWW):

Qhov Zoo:

Nws tuaj yeem tsim cov kav dej tsim cov kab uas ua diameters ntau (feem ntau txog 100 "lossis ntau dua).

Cov khoom siv raw muaj dav thiab muaj tus nqi qis (tshwj xeeb tshaj yog rau cov kav dej loj (}} txoj hauj lwm uas hla kev).

Nws tuaj yeem tsim tau txuas ntxiv thiab muaj kev ua haujlwm siab.

Cov phiaj hlau hlau ntawm tib qhov dav tuaj yeem siv los tsim cov kav hlau sib txawv ntawm cov kab sib txawv (los ntawm kev kho lub helix kaum).

Qhov tsis zoo / txwv:

Weld Seam Seam Ntev yog ntev (1 / kev txhaum (Helix Angle) lub sij hawm the ncig ntawm txoj kab ntawm cov yeeb nkab ntawm cov hlau).

Cov duab geometric qhov tseeb (xws li melamicity thiab ncaj) tej zaum yuav ua tsis tau zoo me ntsis rau lsaw kav.

Muaj peev xwm nyob tau teeb meem kev ntxhov siab (tshwm sim los ntawm cov txheej txheem moulding).

Cov morphology ntawm tshav kub -} be} cuam tshuam thaj chaw (Hz) ntawm Weld Seam yog qhov nyuaj. Kev ntev Weld ntev ntawm nws yog 1.3 txog 2 zaug uas ntawm txoj kab ncaj ncaj.

Weld leeg tau muab cov khoom faib tshaj tawm. Thaum raug rau sab hauv siab, cov kev ntxhov siab hauv lub xeev nyob rau hauv cov kev npau suav thiab cov lus qhia axial yog qhov txawv ntawm cov ntawm cov leeg sab hauv. The theoretical phab ntsa tuab xam hauv cov xa hluav taws xob hauv kev tsim qauv pipeline feem ntau yuav tsum tau nce ntxiv.

YEEB:

Nws hais txog tubular khoom. Nws txawv ntawm cov yeeb nkab fittings, flanges lossis lwm hom khoom lag luam hlau. Ntawm no nws tshwj xeeb hais txog qhov kev cai yeeb nkab ncaj ncaj siv rau kev thauj cov kua dej.

• Qhov no yog dab tsi? Qhov no yog hom welded steel yeeb tuaj yeem tsim raws li lub ntiaj teb cov qauv API 5L tus qauv thiab siv rau kev thauj khoom ntawm cov kua xws li roj thiab nkev.

• Lub zog qib: iT Belongs rau nruab nrab lub zog qib siab (X52), muaj tsawg kawg nkaus zog zog ntawm 52,000 psi (360 MPA).

• Qib Zoo:PSL1 belongs rau qib theem pib. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tseeb tias feem ntau nws tsis tuaj yeem lav cov qes qes- kub cuam tshuam todness. Qhov no txhais tau tias cov yeeb nkab no tsis haum rau cov cheeb tsam txias lossis qis {{{{} Kev pheej hmoo ntawm kev pab cuam yuav siab dua ntawm cov kub tsawg. Qhov ntsuas kub yuav tsum tau ntsuas ua ntej thov.

• Yuav Ua Li Cas Siv Ua:Nws yog tsim los ntawm kauv submerged arc vuam txheej txheem. Qhov no txhais tau tias lub npoo weld yog ib txoj kab ntev. Cov Welds tau undergone ua tsis tu ncua ut lossis et kev kuaj thiab hydrostatic kev ntsuam xyuas.

• Daim ntawv thov tseem ceeb tshaj plaws:

Roj thiab roj sib sau ua ke thiab kev thauj mus los hauv hluav taws xob (nrog nruab nrab siab)

Dej Qhov Dej lossis Dej Kis Tau Kev Tiv Thaiv Dej Dej ntawm Dej Kho Nroj Tsuag

Tsawg - qhov siab loj-} riam rau hauv dej (kev lag luam tshuaj, hwj chim, thiab lwm yam)

Yeeb Nkab Piles, Pawg Tsav Tsheb, Thiab Cov Kav Kav (Ntawm Qhov No, Ntau Saib Xyuas Yog Them Rau Cov Khoom Siv Zog, Thiab Qhov Yuav Tsum Tau Ua Kom Tau)

• Tsis muaj feem cuam tshuam cov xwm txheej:Tsawg - huab cua qhov dej txias, siab {} qhov siab tseem ceeb heev pob tw kab, thiab qee zaus yuav tsum muaj qhov yuav tsum muaj rau kev nruj.

• Cov ntsiab lus tseem ceeb:Nws yog tus nqi -}} Pib rau loj- txoj hauj lwm uas hla hla. Ua tau raws li cov kev cai yuav tsum tau ntawm API 5L txheem.Nws yuav tsum raug sau tseg tias qhov tsis txaus ntseeg ntawm kev rov sia ntawm PSL1 qib yog nws cov qauv tsim losion txwv. Thaum xaiv cov phiaj xwm tseem ceeb, cov kev pabcuam yuav tsum tau ua tib zoo ntsuas. Cov txheej txheem vuam yog qhov tseem ceeb tshaj plaws, thiab kev ua haujlwm ntawm welded sib koom tes (tshwj xeeb yog cov cua sov- kev kub ntxhov) yuav tsum tau muab rau kev saib xyuas.

• Cov Khoom Siv Ntaus:Cov yeeb nkab xaus feem ntau yuav tsum tau kho (xws li bevels), thiab qee zaus anti {{0}
