Cov Ntawv Thov
Cov ntawv thov tshwj xeeb rau API 5L cov yeeb nkab steel muaj xws li:
1. Ntughia roj platform tsim
Siv hauv kev tsim kho cov pa roj teeb xws li tim Nkij teb chaws, X70 tus leeg ncaj leeg Submerged Arc Welded Yeeb Nkab (LSAWW) yog siv los txhawb lub platform qauv.
01
2. Ntev cov roj ntev thiab roj pipeline
Nws yog dav siv nyob rau hauv nruab nrab thiab cov roj siab siab los ntawm roj thiab nkev, npog ib puag ncig ntawm thaj av mus rau seabed. Piv txwv li, sib txawv steel qib xws li X42 mus rau X42 mus tau los ntsib kev sib txawv ntawm cov kev siab thiab qhov kub thiab txias
02
3. Kev siab siab siab xa xov
API 5L steel leeg ntawm cov roj hlau siab (EG X80) tau siv roj hauv cov roj thiab roj av ua kom nruj, piv txwv li kev txhim kho cov roj hauv hiav txwv tsis sib haum, piv txwv li siv / rt) kom paub tseeb.
03
4. Tshwj xeeb ib puag ncig engineering
- Acidic ib puag ncig: Sulfur resistant steel (xws li C110) yuav tsum tau siv thiab cim nrog tus lej "Suffix.
- Qhov xwm txheej kub tsawg x 65 / x70 yog qhov haum rau kev sib kis tau rau roj tsis tshua muaj qhov chaw txias heev.
- Cov Kev Pab Cuam Marine: Cov kav hlau steel khij cim nrog cov ntawv qhia "o" ntsib API 17d txhim kho cov qauv rau othore platform piping.

5. Kev Lag Luam Hauv Nroog thiab Kev Lag Luam
Qee cov lus qhia tshwj xeeb (xws li J55 / N80)
