Ib Qhov Chaw Tsim Nyog Ua Ntej Ua Ntej
ASTM A53 raws li kev sau ntawv txhais tau peb hom kev tsim khoom - Hom F (lub qhov cub- taub qab-weld), Hom E (hluav taws xob-kuj-weld), thiab Hom S (seamless) - thiab tsis qhia meej lub npe helical / kauv vuam raws li hom plaub. Hauv kev xyaum, txawm li cas los xij, qhov kev sib xyaw ua ke no muaj tseeb thiab lees txais thoob plaws hauv kev lag luam hauv ib txoj kev tshwj xeeb: mills tsim loj -inch helical- seam yeeb nkab nquag siv thiab sim nws kom tau raws liA53 Qib B cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab, muab ntawv pov thawj tawm tsam cov kev xav tau txawm tias cov txheej txheem vuam nws tus kheej nyob sab nraum A53 cov npe hom ntawv.
Qhov no txawv ntawm stamping lub phaj mismatch rau ib yam khoom - nws yog ze rau siv A53 Qib B raws li tau txais chemistry / lub zog siv taw tes rau ib tug loj - cov khoom kab uas A53 tus kheej scope tsis ncav cuag qhov luaj li cas (A53 lub kaus mom ntawm NPS 26" / 660 mm } zoo li qub ). Cov txiaj ntsig tau zoo yog cov khoom lag luam uas coj tus cwj pwm zoo li A53 Qib B raws li cov khoom siv, tsim los ntawm cov txheej txheem A53 tsis loj rau cov neeg muab khoom lag luam muaj npe tau meej meej txog qhov sib txawv ntawm daim ntawv pov thawj zeb tsis tshua muaj kev paub txog qhov sib txawv tiv thaiv koj li.
Qhov twg cov khoom no zaum ntawm peb qhov loj -Txoj kab uas hla Specs
Helical- seam yeeb nkab tau lees paub rau A53 Qib B tsis yog qhov kev xaiv tshwj xeeb ntawm SSAW kab - nws yog ib qho ntawm peb txoj hauv kev, thiab xaiv qhov yog nyob ntawm kev pabcuam:
ASTM A53 Qib B (lub hom phiaj dav)- lub neej ntawd siv thaum daim ntawv thov yog structural, mechanical, lossis cov kua dej dav dav thauj khoom (tsis yog- dej tseem ceeb, huab cua, qis- siab chav) thiab tsis xav tau cov raj xa dej- cov ntaub ntawv qib API 5L lossis pawg -kev ntsuas tshwj xeeb ntawm A252. Qhov no yog qhov "zoo dav- lub hom phiaj steel yeeb nkab, raug lees paub zoo" kev xaiv.
API 5L (pipeline kis tau tus mob)- qhov tseeb spec thaum cov yeeb nkab tau nqa roj lossis roj hauv kev sib kis -kab siab. API 5L's PSL1 / PSL2 kev xeem tswj hwm thiab qib ntaiv (A, B, X42 txog X70) yog tsim tshwj xeeb rau cov kav dej kom ncaj ncees uas A53 tsis kuaj rau.
ASTM A252 (nruab nrab)- qhov tseeb spec rau lub hauv paus thiab cov txheej txheem piling, qhov uas yuav tsum tau tswj hwm yog kem lub zog thiab driveability es tsis txhob siab. A252 cov qib (1, 2, 3) yog txhais los ntawm qhov tsawg kawg nkaus tawm los thiab tensile lub zog es tsis yog cov kav dej pab pawg.
Ib txoj kab SSAW zeb ib leeg tuaj yeem tsim cov yeeb nkab rau ib qho ntawm peb qhov tshwj xeeb ntawm tib txoj kab uas hla thiab phab ntsa tuab - qhov kev hloov pauv li cas yog cov kev sim, cov ntaub ntawv, thiab ntawv pov thawj, tsis tas yuav yog lub cev yeeb nkab. Kev txiav txim los ntawm qhov tseeb spec lub npe tseem ceeb vim nws txiav txim siab seb qhov twg tau kuaj thiab daim ntawv pov thawj zeb tuaj yeem thov raws cai.
Yuav ua li cas Helical Weld txawv ntawm Ncaj -Seam A53 Pipe hauv Kev Xyaum
Tsim geometry.Helical (kauv) vuam ua rau lub raj los ntawm winding ib tug steel sawb ntawm lub kaum sab xis thiab welding lub nruam helical seam, piv rau ncaj- seam txheej txheem uas welding ib leeg longitudinal sib koom. Qhov no cia cov mills tsim loj- txoj kab uas hla cov yeeb nkab los ntawm txoj kab uas hla nqaim dua li cov yeeb nkab tiav qhov ncig - vim li cas SSAW dominates loj - txoj kab uas hla, tus nqi -sensitive ntau lawm.
Weld ntev thiab soj ntsuam Scope.Lub helical seam yog qhov ntev dua rau ib chav tsev ntawm cov yeeb nkab ntev dua li lub seam ncaj, uas txhais tau hais tias muaj ntau qhov vuam los kuaj xyuas. Reputable SSAW mills khiav nruam automated ultrasonic kuaj raws cov kauv seam thaum lub sij hawm ntau lawm es tsis yog qhov chaw - xyuas, precisely vim lub seam ntev ua rau sampling tsawg tus neeg sawv cev tshaj nws yuav nyob rau hauv ib tug luv luv seam.
Roundness thiab tawm - ntawm - roundness kam rau ua.Cov kauv- txheej txheem tsim muaj peev xwm ua kom muaj qhov sib luag zoo sib xws piv rau qee qhov ncaj- seam loj- txoj kab uas hla, uas yog ib feem ntawm vim li cas SSAW feem ntau nyiam rau qhov loj - txoj kab uas hla dej thiab qis - cov roj hluav taws xob tseem ceeb txawm tias sab nraum cov nqi ntshiab.
Ntev yooj.Helical-seam yeeb nkab tuaj yeem tsim tau ntev ntev dua li qhov ncaj-seam loj- txoj kab uas hla, txij li cov coil- cov txheej txheem muab kauv tsis muaj tib lub phaj-ntev qhov txwv uas JCOE- tsim LSAW yeeb nkab ua.
FAQ
Q: Puas yog ASTM A53 officially npog helical / kauv welded yeeb nkab?
A: A53 daim ntawv teev npe suav nrog rau qhov cub- taub qab-weld, hluav taws xob-kuj-weld, thiab seamless - nws tsis meej meej txhais cov helical vuam raws li hom plaub. Nyob rau hauv kev xyaum, loj -diameter helical- seam yeeb nkab yog dav tsim thiab certified rau A53 Qib B's chemistry thiab mechanical khoom yuav tsum tau raws li ib tug lees paub kev lag luam convention, txawm hais tias cov txheej txheem weld nws tus kheej ntog sab nraum tus txheej txheem hom lus txhais.
Q: Dab tsi yog qhov txawv ntawm A53 Qib A thiab Qib B rau helical weld yeeb nkab?
A: Qib B muaj qhov tsawg kawg nkaus tawm los thiab lub zog tensile (240 MPa / 415 MPa) dua li Qib A, thiab yog cov qib uas feem ntau tau teev tseg rau qhov loj - txoj kab uas hla helical yeeb nkab siv hauv cov qauv lossis siab dua - kev siv kev ntxhov siab. Qib A feem ntau yog qhov yuav tsum tau khoov txias lossis coiling.
Q: Kuv puas yuav tsum siv A53 Gr.B lossis API 5L rau cov kav dej xa mus?
A: Rau kev xa tawm tiag tiag- cov kev pabcuam kab hauv qab qhov tseem ceeb, API 5L yog qhov tseeb spec - nws suav nrog cov kav dej- kev ntsuas tshwj xeeb (PSL1/PSL2) uas A53 tsis ua. A53 Qib B yog qhov tsim nyog rau qis dua - siab lossis tsis yog - kev xa dej tseem ceeb uas tsis tas yuav tsum muaj ntawv pov thawj puv kav dej.
Q: A53 Qib B helical weld yeeb nkab puas tuaj yeem siv rau piling?
A: Nws tuaj yeem siv tau raws li kev tsim qauv, tab sis yog tias daim ntawv thov tshwj xeeb yog lub hauv paus lossis cov txheej txheem piling, ASTM A252 yog tus qauv sau ntawv tiag tiag rau kev siv ntawd, nrog rau qib txhais thiab kev ntsuas tsom rau pawg tsav tsheb thiab sab zog. Qhia rau A252 los ntawm lub npe yog tias piling yog qhov npaj siv.
