Dab tsi yog API 5L Sib npaug Qib

Kev kos duab txias tuaj yeem siv los tsim seamlessAPI 5L carbon steel kavnrog me me diameters los yog sib dua phab ntsa. Ib qho txiaj ntsig ntawm kev siv api 5l carbon steel ERW kav dej yog tias tsis tsuas yog lawv muaj qhov tseeb qhov tseeb thiab zoo nkauj, tab sis lawv kuj tsis tshua kim dua piv rau cov kav dej seamless. Ntxiv rau ERW vuam, API 5L carbon steel welded kav kuj tuaj yeem tsim siv DSAW lossis LSAW thev naus laus zis. API 5L kab yeeb nkab PSL1 welded nrog DSAW siv ob qhov hla ntawm submerged arc vuam, thaum LSAW tshuab siv zonal welds ntawm cov ntawv kub dov.
American txuj
Lub koom haum American Petroleum (API) 5L tus qauv txhais tau ntau qib ntawm cov kab yeeb nkab raws li lawv cov khoom siv thiab cov tshuaj muaj pes tsawg leeg. Thaum cov ntaub ntawv xav tau kom tau raws li cov kev cai thoob ntiaj teb lossis hauv cheeb tsam, cov qib sib npaug rau lwm cov qauv feem ntau nrhiav.
Cov qauv thoob ntiaj teb
ISO 3183: ISO 3183 yog tus qauv thoob ntiaj teb uas qhia txog kev tsim khoom rau cov yeeb nkab steel. Nws muaj qib sib npaug rau API 5L thiab tau txais los ntawm ntau lub tebchaws. ISO 3183 cov qhab nia sib npaug feem ntau yog tsim los ntawm tsab ntawv "L" ua raws li tus lej sib raug rau qhov tsawg kawg nkaus yield zog hauv megapascals (MPa). Piv txwv li, ISO 3183 L290 yog sib npaug rau API 5L Qib X42.
European txheem
EN 10208-2: Cov txheej txheem European no npog cov kav hlau siv hauv cov kav dej uas muaj cov nplaim taws. EN 10208-2 muaj qhov sib npaug rau API 5L thiab feem ntau siv hauv cov haujlwm European. Piv txwv li, EN 10208-2 L360MB yog sib npaug rau API 5L Qib X52.
German txuj
DIN 17172: Tus qauv German no qhia txog cov txheej txheem kev xa khoom rau cov kav hlau siv los thauj cov nplaim hluav taws. DIN 17172 muaj qib sib npaug rau API 5L thiab feem ntau siv hauv Tebchaws Yelemees thiab lwm lub tebchaws nyob sab Europe.
British qauv
BS 3601: BS 3601 yog British Standard npog cov pa roj carbon steel kav thiab cov raj siv hauv kev siv siab. Txawm hais tias tsis yog raws nraim li API 5L, nws tuaj yeem siv rau hauv qee qhov kev siv. BS 3601 Qib 430 qee zaum suav tias yog sib npaug rau API 5L Qib B.
Japanese txuj
JIS G 3457: JIS G 3457 yog ib qho Japanese tus qauv qhia cov pa roj carbon steel kav rau kev siv kav dej. Txawm hais tias tsis yog ib qho kev sib tw rau API 5L, JIS G 3457 piping tuaj yeem siv rau cov ntawv thov tshwj xeeb. JIS G 3457 STPY yog qee zaum siv los ua tus qauv sib npaug rau API 5L Qib B.
Tuam Tshoj txheem
GB / T 9711: Tus qauv no qhia txog cov txheej txheem kev xa khoom rau cov kav hlau rau cov roj thiab kev thauj mus los. GB / T 9711 thiab API 5L muaj qib sib npaug thiab feem ntau siv hauv Suav teb. Piv txwv li, GB / T 9711 L415 yog sib npaug rau API 5L Qib X60.
