FAQ
API 5L X56 txhais li cas?
Nyob rau hauv API 5L, "X56" txhais tau hais tias cov yeeb nkab muaj qhov ntsuas qhov tsawg kawg nkaus ntawm 56,000 psi, sib npaug rau 386 MPa. X qhia txog ib kab- cov yeeb nkab qib npe los ntawm nws cov ksi yield, thiab cov khoom tag nrho yog API 5L X56 ERW yeeb nkab (tseem hu ua API 5L X56 HFW yeeb nkab). Qhov sib npaug ISO 3183 / GB / T 9711 yog L390.
Puas yog ERW tib yam li HFW rau API 5L X56 yeeb nkab?
Yog lawm. ERW (Electric/Resistance Welded) thiab HFW (High Frequency Welded) piav txog tib lub siab -frequency resistance-welded yeeb nkab. API 5L's 47th edition siv HFW raws li lub sij hawm nyiam, tab sis API 5L X56 kuj welded yeeb nkab, ERW thiab HFW yog interchangeable nyob rau hauv kev yuav khoom thiab tshuaj xyuas.
Qhov txawv ntawm API 5L X56 PSL1 thiab PSL2 yog dab tsi?
PSL2 yog nruj dua. Rau cov yeeb nkab welded, PSL2 carbon max yog 0.22% piv rau 0.26% rau PSL1, phosphorus 0.025% vs 0.030%, sulfur 0.015% vs 0.030%, nrog rau qhov yuav tsum tau carbon sib npaug CE IIW Tsawg dua lossis sib npaug ntawm kev ua haujlwm siab tshaj li 0.43% thiab sib npaug ntawm qhov kev cuam tshuam ntawm 0.43% 27 J, ib leeg siab dua lossis sib npaug rau 20 J). PSL2 kuj tseem muaj cov txiaj ntsig ntawm 386-544 MPa. PSL1 tsis muaj cov txiaj ntsig siab, tsis muaj CEV qhov yuav tsum tau ua thiab tsis muaj kev sim cuam tshuam, yog li nws tsis haum rau qaub lossis qis -kev pabcuam kub.
Dab tsi yog qhov ntev thiab qhov loj ntawm X56 ERW yeeb nkab?
API 5L X56 ERW yeeb nkab feem ntau yog muab los ntawm OD 21.3–660 mm (NPS ½–26) nrog phab ntsa thickness 2.0–25 mm hla Teem caij 10 txog XXS, nyob rau hauv ntev ntawm 6–12 m (los yog ob chav random). ERW/HFW haum me me - mus rau - nruab nrab diameters; Qhov ntau thiab tsawg tshaj NPS 26 feem ntau hloov mus rau LSAW lossis HSAW.
Dab tsi yog cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm API 5L X56?
Rau welded yeeb nkab: PSL1 carbon max 0.26%, manganese 1.40%, P 0.030%, S 0.030%; PSL2 carbon max 0.22%, Mn 1.40%, P 0.025%, S 0.015%, CE IIW Tsawg dua lossis sib npaug 0.43%. Mechanically, qhov tsawg kawg nkaus tawm los yog 386 MPa (56 ksi); PSL1 tensile min yog 490 MPa uas tsis muaj sab sauv, thaum PSL2 tawm los yog 386-544 MPa thiab tensile 490-758 MPa, nrog 0℃cuam tshuam ntau dua lossis sib npaug rau 27 J.
Cov qib dab tsi sib npaug rau API 5L X56?
Rau qhov sib npaug API 5L X56, cov qhab nia ncaj qha yog ISO 3183 L390, GB/T 9711 L390, EN 10208-2 L390MB (legacy, tam sim no EN ISO 3183), CSA Z245.1 Qib 390, thiab DN Grade 390{100}{101} OSF} 390 - tsis yog Qib 450, uas yog X65/L450. Tsis muaj qhov ncaj qha ASTM kab-pipe qib; qhov ze tshaj plaws qauv analog yog ASTM A572 Gr.55 (phaj, tsis yog yeeb nkab).
API 5L X56 ERW puas tuaj yeem siv rau kev pabcuam qaub (H2S)?
Tsuas yog API 5L X56 PSL2 tuaj yeem teev rau qaub (ntub H2S) kev pabcuam, muab rau NACE MR0175 / ISO 15156 nrog tswj cov sulfur tsawg dua lossis sib npaug li 0.015% thiab txheeb xyuas los ntawm HIC (NACE TM0284) thiab SSC (NACE TM0177) kuaj, ntxiv rau kev kho cua sov. PSL1 yuav tsum tsis txhob siv rau hauv qhov chaw ntub dej H2S vim tias nws cov MnS suav nrog yog HIC qhov pib.
Kuv yuav thov li cas rau qhov API 5L X56 ERW yeeb nkab?
Xa cov qauv thiab qib (API 5L X56 PSL1 los yog PSL2), sab nraud txoj kab uas hla × phab ntsa thickness, kom muaj nuj nqis, ntev, tiav tiav, txheej, thiab tej yam tshwj xeeb uas yuav tsum tau (qhov kub thiab txias, qaub kev pab cuam, hardness txwv) ua ke nrog lo lus uas peb chaw nres nkoj. Peb pab neeg ua haujlwm tau lees paub qhov tshwj xeeb thiab xa rov qab cov lus hais nrog lub sijhawm ua haujlwm hauv 24 teev.
