Cov khoom muaj pes tsawg leeg thiab cov qauv tsim khoom:
- API 5LX70 Kab Pipes rau roj & roj: cov yeeb nkab no ua raws li API 5L specification rau kev lag luam roj thiab roj. Nws muaj feem ntau tsawg dua 0.26% carbon, tsis pub ntau tshaj 0.65% manganese, thiab tsis ntau tshaj 0.030% ntawm phosphorus thiab sulfur. Tsis tas li ntawd, nws muaj qhov tsawg kawg nkaus lub zog ntawm 485 MPa thiab lub zog tensile yam tsawg kawg nkaus ntawm 570 MPa.
- A53 Steel Pipe: qhov no yog cov pa roj carbon steel yeeb nkab, uas tau muab faib ua peb qib, A, B thiab F. A53-A feem ntau sib raug rau Suav Q235 steel, thiab A53-B sib raug rau Q235, 20 # hlau. Lub ntsiab muaj pes tsawg leeg thiab kev tsim khoom ntawm A53 steel yog txawv ntawm API 5LX70.
Mechanical zog thiab daim ntawv thov thaj chaw:
- API 5LX70 Yeeb Nkab rau kev thauj mus los siab roj: cov pa roj carbon seamless steel kab yeeb nkab no muaj lub zog siab thiab tawv, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ua haujlwm huab cua, xws li kub, kub siab lossis corrosive ib puag ncig. Nws cov txheej txheem tsim muaj xws li steelmaking, dov, tho thiab kho cua sov, uas yuav tsum tau siv cov khoom siv ntau lawm thiab kev tswj xyuas nruj.
- A53 steel yeeb nkab: Txawm hais tias A53 steel yeeb nkab kuj tseem siv rau kev tsim qauv, xws li kev txhawb nqa hauv tsev, nws yog siv rau cov kav dej thiab cov qauv hauv qab qis qis lossis qhov chaw tsis muaj corrosive. Nws cov khoom siv kho tshuab, thaum muaj peev xwm ua tau raws li qee qhov kev xav tau ntawm engineering, feem ntau tsis hloov mus rau qhov xwm txheej hnyav li API 5LX70 steel yeeb nkab.
Txhawm rau kom ua tiav, API 5LX70 Cov roj thiab cov kav dej yog qhov tsim nyog rau kev siv roj thiab roj kev lag luam hauv qhov kub thiab txias, kev kub siab thiab corrosive ib puag ncig, thaum A53 steel yeeb nkab feem ntau siv rau hauv tsev thiab kev txhawb nqa kev tsim kho.
