API 5L X42 PSL2 SAW 3PE Anti-corrosion kauv welded steel yeeb nkab

API 5L X42 steel yeeb nkab & API 5L X42 PSL2 yeeb nkab muaj lub zog tensile siab, hardness thiab toughness los tiv thaiv puas thiab tawg. Qhov ntxiv zoo weldability. Kev tsim cov haujlwm zoo li flanging, vuam lossis dabtsi yog khoov yog zoo haum rau X42 Yeeb Nkab Khoom & API 5L X42 ERW Yeeb Nkab.

Ntau yam los ntawm Manufacturing Types
Seamless: suav nrog kub dov seamless thiab txias kos seamless, diameters mus txog 24 nti ib txwm.
ERW: Hluav taws xob Resistance Welded, OD txog 24 nti.
DSAW / SAW: Ob chav Sub-merged Arck Vuam, hloov txoj kev vuam dua li ERW rau cov kav dej loj dua.
LSAW: Longitudinal Sub-merged Arc Vuam, tseem hu ua JCOE yeeb nkab, OD txog li 56 nti. JCOE muaj npe los ntawm kev tsim cov txheej txheem nrog J Shape, C zoo, O zoo thiab txias nthuav dav txheej txheem los tso cov yeeb nkab lub zog thaum hloov pauv.
SSAW / HSAW: Kauv Sub-merged Arc Vuam, lossis Helical SAW, diameters txog 100 nti
