Seamless steel yeeb nkabASTM A53, SCH40, Gr.B yog cov yeeb nkab steel zoo siv dav hauv kev ua lag luam, nrog kev ua tau zoo thiab ntau hom kev thov. Cov hauv qab no yog kev qhia txog qhov zoo ntawm cov yeeb nkab steel:

Khoom siv thiab Standard
ASTM A53tus qauv yog ib tug nruj specification rau seamless steel kav nyob rau hauv lub US steel kev lag luam, feem ntau yog siv rau roj, natural gas, chav thiab lwm yam kav dej. Cov yeeb nkab steel no yog ua los ntawm cov hlau tsis muaj hlau lossis cov hlau tsis tshua muaj hlau. Qib B (Gr.B) qhia tau hais tias cov yeeb nkab muaj lub zog siab thiab kev ua haujlwm siab thiab tsim nyog rau qhov nruab nrab thiab siab kub. SCH40 yog hais txog tus qauv ntawm cov yeeb nkab phab ntsa tuab, uas ua kom cov yeeb nkab muaj kev tiv thaiv corrosion txaus thiab lub peev xwm siab.

Cov txheej txheem ntau lawm thiab zoo
Cov yeeb nkab steel no siv cov tshuab seamless steel yeeb nkab ntau lawm los xyuas kom meej cov khoom ruaj khov zoo, cov yeeb nkab du, tsis muaj vuam tsis xws luag, thiab zoo heev siab tsis kam thiab corrosion kuj. Los ntawm kev soj ntsuam nruj nruj, nws ua tau raws li qhov yuav tsum tau ua ntawmASTM A53tus qauv los xyuas kom meej tias lub zog, hardness, ductility thiab corrosion kuj ntawm txhua cov yeeb nkab steel raws li cov qauv kev lag luam.

Specifications thiab Scope ntawm daim ntawv thov
Seamless steel yeeb nkab muaj ntau yam kev qhia tshwj xeeb, suav nrog cov kab dav dav dav xws li 1/8 "rau 30", thiab phab ntsa tuab tuaj yeem kho raws li kev xav tau. Nws yog dav siv hauv kev lag luam roj av, tshuaj lom neeg, hluav taws xob, nkoj tsim, tshuab, thiab lwm yam, tshwj xeeb tshaj yog tsim rau cov kav dej uas thauj cov dej tawm xws li dej, roj, thiab roj.

Siv dav
ASTM A53seamless steel yeeb nkab yuav siv tau rau high-pressure kis tau tus mob pipelines, lub tsev, boiler pipelines, roj thiab natural gas kis pipelines, thiab lwm yam.
