L485 steel yeeb nkab belongs rau PSL2 qib pipeline steel hauv API 5L tus qauv. Nws cov yam ntxwv tseem ceeb yog tshwm sim hauv peb yam:
Ua ntej, nws qhov tsawg kawg nkaus lub zog ntawm 485MPa muab nws zoo heev tiv thaiv deformation, zoo tiv thaiv kev ntxhov siab los ntawm geological txav thaum thauj siab - roj thiab roj nyob rau hauv qhov ntev.
Thib ob, los ntawm cov txheej txheem quenching thiab tempering (QO) cov txheej txheem, cov khoom muaj kev cuam tshuam lub zog ntawm ntau tshaj 20J txawm nyob rau ntawm -10 degree, zoo dua li cov pa L485 steel yeeb nkab.
Qhov thib peb, qhov sib npaug ntawm cov pa roj carbon monoxide yog tswj tau qis dua 0.43%, thiab nrog rau qhov sib ntxiv ntawm microalloying ntsiab xws li Nb thiab V, qhov sib npaug ntawm lub zog thiab weldability yog tiav. Nws yog ib qho tsim nyog sau cia tias cov khoom siv no yuav tsum dhau HIC (hydrogen- ua kom tawg) thiab SSC (sulfide stress corrosion) kev ntsuam xyuas kom muaj kev nyab xeeb hauv cov cheeb tsam hnyav uas muaj hydrogen sulfide.

FAQ
Puas yog API 5L zoo ib yam li A106?
API 5L muaj ntau qhov ntau thiab tsawg los npog ntau qhov kev xav tau los ntawm cov kav dej me me mus rau cov kav dej loj, thaum ASTM A106 tsom feem ntau ntawm cov kav dej seamless rau siab - kev pabcuam kub thiab tsim nyog rau cov haujlwm nrog me me mus rau nruab nrab diameters thiab siab - kev ua tau zoo.
API txhais li cas hauv steel?
API, luv luv rau American Petroleum Institute, raug suav hais tias yog cov cai tshaj lij thiab cov ntsiab lus dav dav rau kev lag luam roj thiab roj.
Qhov txawv ntawm API 5L thiab A53 yog dab tsi?
API 5L: Feem ntau yog siv rau ntev -kab raj xa dej hauv kev lag luam roj thiab roj. - ASTM A53: Dav siv rau kev siv dav dav hauv cov kav dej thiab kev tsim kho. - ASTM A106: Tsim nyog rau kev lag luam uas muaj qhov kub thiab txias siab.
