API 5L faib cov yeeb nkab rau hauv ob theem: PSL1 thiab PSL2
PSL1(Product Specification Level 1) feem ntau tsom rau cov khoom siv kho tshuab thiab cov tshuaj lom neeg muaj pes tsawg leeg, yam tsis muaj kev sim nruj thiab cov xwm txheej ntxiv rauPSL2. PSL1 cov kav dej kav dej feem ntau yog siv hauvlow-siab lossis nruab nrab-siab ib puag ncig, xws li onshore roj thiab roj xa mus kav dej, uas tus nqi -kev ua tau zoo thiab kev ua tau zoo yog qhov tseem ceeb.
Tshuaj muaj pes tsawg leeg
PSL1 cov kav dej muaj cov ntsiab lus yooj yim carbon thiab alloying ntsiab. Lawv feem ntau yog ua los ntawmcarbon hlaunrog me me ntawm manganese thiab silicon los xyuas kom meej lub zog thiab weldability. Nyob rau hauv sib piv,PSL2 cov kav dej lossis siab dua - cov kav dej (xws li cov siv rau siab - siab lossis qis - qhov kub thiab txias) tej zaum yuav muaj cov ntsiab lus alloying ntau dua, xws lichromium, nickel, los yog molybdenum, los txhim kho corrosion kuj thiab toughness. Qhov sib txawv no ua rauPSL1 cov kav dej raug nqi ntau dua -zoovim cov ntaub ntawv yooj yim dua thiab cov txheej txheem tsim khoom. Piv txwv li, PSL1 kav yuav raug nqintau txhiab RMB ib tuj, thaum siab dua - cov kav dej tuaj yeem ncav cuagkaum txhiab RMB ib tuj, nyob ntawm specifications thiab ua lag luam tej yam kev mob.
Mechanical Performance
PSL1 pipeline kav feem ntau ntsibAPI 5L cov kev cai yooj yimrau yield thiab tensile lub zog, nrogyield zog ntawm 240 MPa rau 550 MPa, nyob ntawm qib (piv txwv li, X42, X52, thiab lwm yam). Cov khoom no txaus raufeem ntau cov pa siv, xws li cov kav dej hauv nroog lossis cov roj sib sau ua ke. Txawm li cas los xij, piv rau PSL2 cov kav dej, PSL1 kav yuav muajweaker cuam tshuam toughness thiab tawg toughness.
PSL2 cov kav dej xav tauKev soj ntsuam nruj dua thiab tsis yog -kev tshuaj ntsuam xyuas kev puas tsuaj (NDT) kom muaj kev nyab xeeb nyob rau hauv ib puag ncig hnyav (piv txwv li, qis- kub lossis siab - lub zog siab). PSL1 kav dej zoo dua rauKev nyab xeeb me me thiab qis - siab, thaumPSL2 cov kav dej yog siv nyob rau hauv ib puag ncig huab cua, zooArctic cheeb tsam los yog tob -sea pipelines.

Khoom siv thiab kev tsim khoom
Cov hlau rau ob qho tib si seamless thiab welded yeeb nkab yuav tsum tau ua los ntawm ib los yog ntau tshaj ntawm cov txheej txheem hauv qab no: qhib-heart, hluav taws xob rauv, los yog yooj yim- oxygen. Weld seam ntawm hluav taws xob-tsis kam welded yeeb nkab hauv Qib B yuav tsum tau kho cua sov tom qab vuam.
