- X52 PSL1, yog tsim los tiv thaiv ntau dua kev ntxhov siab thiab yog qhov tsim nyog rau cov ntawv thov uas xav tauNtau dua cov kev ntsuas siab.
- X42 PSL1, nrog nwsTxo lub zogtiamsissiab dua ductility, tej zaum yuav siv rau hauv cov ntawv thov uas hloov pauv thiab muaj peev xwm ntau dua yog qhov tseem ceeb tshaj qhov muaj zog.
Cov Ntawv Thov
Ob chav kawm tau siv nyob rau hauv kev thauj mus los ntawm roj av thiab nkev.
- API 5L X52 PSL1, nrog nwsLub zog siab dua thiab cov kev ntsuas siab, yog siv ntau daim ntawv thov xav tau ntau dua, suav nrog cov roj siab thiab roj roj thiab lwm cov txheej txheem uas xav tau nyob qhov twg.
- API 5L X42 PSL1, nrog nwsTxo lub zog tab sis qib siab dua, tej zaum yuav siv rau hauv cov ntawv thov uas hloov pauv thiab muaj peev xwm ntau dua yog qhov tseem ceeb tshaj qhov muaj zog.
Nto Kho
Cov kev kho kom muaj nuj nqis rau API 5L X42 PSL1 thiab X52 PSL1 tuaj yeem sib txawv raws li kev siv thiab ib puag ncig cov xwm txheej.
Ob txoj kev kawm tuaj yeem dhau los cov kev kho mob xws li:
- Zeb nplai (raws li-rolled): qhov no yog lub ntuj nto txwv tom qab kub dov, uas yog ib qho rau PSL1 kav.
- Varnish txheej: txheej tiv thaiv kev tiv thaiv los tiv thaiv corrosion thaum lub sijhawm khaws cia thiab tsheb thauj mus los.
- Painting: Cov xim dub feem ntau siv rau kev tiv thaiv corrosion ntxiv.
- Fusion Bonded Epoxy (FBE): Ib qho kev tiv thaiv ib txwm muaj rau Corrosion tiv thaiv hauv Pipelines, muab cov nyom ruaj khov tiv thaiv noo noo thiab tshuaj lom neeg.
- 3- txheej polyethylene (3LPE) lossis {}}}} txheej txheem rau kev tiv thaiv xeb sab nraud, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig.
Kev sib txawv hauv kev kho deg:
Thaum ob tus menyuam kawm tuaj yeem tau txais cov kev kho zoo sib xws saum toj no, kev xaiv kev kho mob yuav txawv raws li cov kev cai ntawm daim ntawv thov. Piv txwv li cov qib siab dua qib siab zoo li X52 tej zaum yuav tau txais kev kho kom muaj zog ntxiv lossis ib puag ncig kev nyuaj siab, xws li hauv lub nkoj tob lossis siab.
