API 5L Gr.B tus qauv yog dab tsi?
API 5L Gr.Byog ib tug qauv rau carbon steel pipelines siv nyob rau hauv cov roj thiab roj kev lag luam rau thauj cov roj, natural gas, thiab lwm yam kua. Cov qauv no npog ob qho tib si seamless thiab welded kav thiab yog ib feem ntawm covAPI 5L gas pipelinespecification.
Dab tsi yog qhov txawv ntawm API 5L Gr.B ncaj seam welded steel yeeb nkab thiab cov qauv hlau zoo tib yam (xws li S235JR)?
API 5L Gr.B ncaj seam welded steel yeeb nkabyog tsim tshwj xeeb rau cov roj thiab cov kav dej, muaj cov kev cai nruj ntawm cov tshuaj muaj pes tsawg leeg, thiab muaj zog dua. Hauv qhov sib piv, cov qauv hlau zoo tib yam (xws li S235JR) yog cov khoom siv hauv tsev ntau dua nrog lub zog qis dua.
Dab tsi yog qhov txawv ntawm "ncaj seam welding" thiab "kauv vuam"?
Lub ntsiab sib txawv yog nyob rau hauv cov kev taw qhia weld: nyob rau hauv ncaj seam welding, lub weld seam yog parallel mus rau qhov ntev ntawm cov yeeb nkab, thaum nyob rau hauv kauv welding, ib tug kauv weld seam yog siv. Qhov no ua rau cov yam ntxwv ntau lawm: ncaj seam vuam feem ntau sai dua thiab haum rau cov kav dej me me; thaum kauv vuam qeeb dua tab sis tuaj yeem siv cov hlau nqaim kom txuas cov kav dej loj dua.
Dab tsi yog qhov tseem ceeb ntawm daim ntawv thov API 5L Gr.B ncaj seam welded steel yeeb nkab?
API 5L Gr.B ncaj seam welded steel yeeb nkabyog siv nyob rau hauv cov roj, roj, thiab petrochemical industries rau kev thauj mus los kua. Lwm qhov kev thov tseem ceeb suav nrog kev tsim hluav taws xob, cov hlab ntsha siab, kev ua kom qab zib, thiab kev siv engineering dav dav.
Kev tiv thaiv sab hauv corrosion ua li cas ntawm API 5L Gr.B ncaj seam welded steel yeeb nkab?
Internal corrosion tiv thaiv rauAPI 5L Gr.B ncaj seam welded steel yeeb nkabsuav nrog kev siv cov txheej txheem tiv thaiv, xws li epoxy sab hauv lossis 3LPE txheej, lossis siv cov tshuaj tiv thaiv cathodic.
