1. ** ** Kev qhia tshwj xeeb ntawm API 5L X65 ** **:
API 5L X65 yog qib kab kab hlau txhais los ntawm API 5L cov lus qhia tshwj xeeb. Nws muaj tsawg kawg yog cov txiaj ntsig lub zog muaj zog ntawm 65,000 psi (448 MPA) thiab feem ntau siv cov roj roj siab thiab roj tsheb. Nws ua raws li cov qauv xws li PSL1 lossis PSL2, nrog PSL2 muab cov khoom siv thiab cov neeg kho tshuab sab nrauv.
2. ** Thickness ntawm API 5L X52 **:
API 5L X52 tsis muaj qhov tuab tuab li nws txawv raws li cov yeeb nkab loj thiab daim ntawv thov. Cov tuab tuab ib txwm muaj los ntawm 0.25 nti (6.35 mm) rau ntau tshaj 1 nti (25.4 hli) lossis ntau dua ntawm cov kab ntsig thiab kev tsim khoom (seamless lossis welded).
3. ** API 5L X52 Sib npaug ":
API 5L X52 yog sib npaug rau lwm cov qauv thoob ntiaj teb xws li ISO 3183 L360 (tib yam zog zog: 52,000 psi lossis 360 mpa). Nws kuj tseem piv rau ASTM A106 qib B (rau seamless) thiab ASTM A53 qib B (rau welded kav dej) nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab.
4. ** ERW hauv cov yeeb nkab **:
ERW (hluav taws xob tiv thaiv whard) Nws yog ib qho siv rau cov ntawv thov qis-rau-nruab nrab hauv nruab nrog hauv cov roj, roj av, thiab dej thauj. ERW kav yog tus nqi-ua tau zoo thiab muaj nyob rau ntau qhov ntau.
5. ** Yog API 5L Seamless? **:
API 5L npog ob leeg seamless thiab welded (erw, lsaw, thiab lwm yam) kav dej. Seamless kav yog ib feem ntawm API 5L specification thiab tsim tawm yam tsis muaj Weld Seam, ua rau lawv haum rau cov ntawv thov siab. Tus qauv tso cai rau kev tsim cov txheej txheem sib txawv raws cov cai thov.
