Khoom cim npe

L360 Pipeline Steel, Lub Hom Phiaj: API SPEC 5L-2011 (Pipeline Specification), tsim thiab luam tawm los ntawm American Petroleum Institute, yog siv thoob ntiaj teb.Pipepipe: Txhawm rau thauj cov roj, roj lossis dej tawm hauv av los ntawm cov kav dej mus rau kev lag luam roj thiab roj.Pipeline yeeb nkab suav nrog seamless thiab welded yeeb nkab ob yam, cov yeeb nkab kawg muaj qhov kawg, threaded kawg thiab lub qhov (socket) kawg;Kev sib txuas hom yog kawg vuam, hoop kev twb kev txuas, qhov (socket) txuas thiab lwm yam.Cov khoom tseem ceeb ntawm lub raj yog B, X42, X46, X56, X65, X70 thiab lwm yam steel qib.Peb lub tuam txhab dhau qhov API certification (API 5CT thiab API 5L) thaum Lub Yim Hli 2009.

L360 Pipeline Steel, API SPEC 5L GB / T9711.1 GB / T9711.2 Tuam Tshoj National Standard Daim ntawv thov: Oxygen, dej thiab roj xa cov kav dej hauv kev lag luam roj thiab roj av B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485

Nrog rau txoj kev loj hlob ntawm cov yeeb nkab steel phaj technology thiab cov kev kawm ntawm welded yeeb nkab txoj kev, vuam tshuab, daim ntawv thov ntau yam ntawm cov yeeb nkab nrog welded yeeb nkab nyob rau hauv maj expanding, tshwj xeeb tshaj yog nyob rau hauv lub loj txoj kab uas hla welded yeeb nkab chav kawm ntawv muaj qhov zoo dua qhov pom tseeb, thiab cov nqi tseem ceeb, welded yeeb nkab tau tseem ceeb nyob rau hauv lub teb ntawm kab yeeb nkab, uas txwv txoj kev loj hlob ntawm stainless hlau seamless steel kab yeeb nkab.Nyob rau hauv 2004, cov zis ntawm seamless pipeline yog hais txog 400,000 t, steel qib muaj xws li X42-70, thiab ntau yam yog onshore pipeline thiab submarine pipeline.

Kev tsim cov yeeb nkab steel qib siab siv cov txheej txheem kev kho cua sov microalloying, cov nqi tsim khoom ntawm stainless hlau seamless yeeb nkab yog pom tseeb siab dua welded yeeb nkab, thiab nrog kev txhim kho ntawm qib steel, xws li X80 thiab siab dua steel qib pipeline yeeb nkab txwv rau carbon sib npaug. , cov txheej txheem ntawm seamless yeeb nkab yog qhov nyuaj rau kev ua tau raws li cov neeg siv khoom xav tau;Txhua 12Cr1moV alloy yeeb nkab chaw tsim tshuaj paus yog ua cov kev tshawb fawb kev ua hauj lwm nyob rau hauv thiaj li yuav txhim kho cov corrosion kuj ntawm nws cov yeeb nkab yeeb nkab thiab ruaj khov kev ua tau zoo nyob rau hauv qis thiab kub ib puag ncig.
