API 5L L360 Pipeline Steel Phaj Thiab API 5L X52
API 5L L360 yeeb nkab yog cov pa roj carbon tsawg, uas ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw xws li roj thiab roj. API 5L L360 siab zog yeeb nkab muaj qhov tsawg kawg nkaus lub zog ntawm 52ksi. Nws ua raws li API SPEC 5L tus qauv ntawm American Petroleum Institute, npog ob pawg loj ntawm cov kav dej seamless thiab welded kav, thiab muab cov lus qhia meej rau kev siv API 5L L360 pipelines nyob rau hauv ntau yam kev thov scenarios.
API 5L L360 muaj ob yam khoom tshwj xeeb, xws li PSL1 thiab PSL2. Cov tshuaj muaj pes tsawg leeg ntawm PSL2 kuj nplua nuj, suav nrog carbon, manganese, phosphorus, sulfur, silicon, vanadium, niobium thiab titanium. Cov muaj pes tsawg leeg ntawm API 5L X52 PSL1 yog qhov yooj yim, feem ntau yog manganese, phosphorus, sulfur thiab kab kawm ntawm vanadium, niobium thiab titanium.
API 5L L360NS Nace Pipe yog tsim los rau kev ua haujlwm siab thaum xa cov xov xwm corrosive thiab cov pa phem. Rau cov teeb meem txo qis, cov txheej tiv thaiv xws li FPE, galvanizing lossis 3LPE txheej tuaj yeem siv los txhim kho nws cov kev tiv thaiv corrosion, ncua kev pab cuam lub neej ntawm cov kav dej, thiab xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm qhov nruab nrab thaum thauj mus los ntev.
GNEE muab API 5l X52 LSAW kav nrog ib txoj kab uas hla sab nraud xws li 2 ntiv mus rau 24 ntiv tes thiab phab ntsa siab tshaj plaws ntawm 250 hli. Xws li ntau qhov ntau thiab tsawg, ua ke nrog cov phab ntsa sib txawv thiab cov kab sib txuas sab nraud, tau nthuav tawm cov khoom lag luam nplua nuj thiab ntau yam, xws li sch10 txog XXS, uas tuaj yeem phim cov yeeb nkab uas haum tshaj plaws raws li qhov tshwj xeeb siab, ntws thiab lwm yam yuav tsum tau ua.
