ASTM SA210 Qib Ayog cov yeeb nkab carbon steel seamless rau cov boilers nruab nrab thiab qis siab thiab cov khoom siv hloov pauv cua sov. Nws ua raws li cov qauv ntawm American Society for Testing and Materials (ASTM). Nws muaj kev tiv taus kub zoo heev, lub zog compressive thiab kev ua haujlwm vuam. Nws yog siv dav hauv kev tsim boiler thiab cov tshuab pauv cua sov hauv lub zog, tshuaj lom neeg, roj av thiab lwm yam lag luam.
ASTM SA210 Qib Ayog cov hlau uas tsis muaj carbon ntau (C≤0.27%), muaj cov ntsiab lus xws li manganese (Mn 0.93% max) thiab silicon (Si 0.10-0.20%) kom ntseeg tau tias muaj cov khoom siv kho tshuab zoo thiab ua tau zoo.
Cov ntsiab lus sulfur thiab phosphorus tsawg (P≤0.035%, S≤0.035%) txhim kho kev tiv thaiv oxidation kub siab.
Kev ua tau zoo heev
Kev kub siab ua haujlwm: kub ua haujlwm ntev ≤450 ℃, luv luv txog li 480 ℃.
Kev coj siab siab: tsim rau cov kav dej boiler nruab nrab thiab qis siab ≤5.88MPa.
Kev sib raug zoo ntawm cov txheej txheem: yooj yim rau vuam, khoov thiab txias, tsim nyog rau cov ntawv raj boiler, cov taub hau thiab lwm yam khoom.
Cov qauv nruj
Ua raws liASTM SA210 Qib Acov qauv, thiab dhauGB/T 3087, ASME thiab lwm yam ntawv pov thawj kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab.
ASTM SA210 GrA seamless steel yeeb nkab yog qhov kev xaiv zoo tshaj plaws rau cov teb hauv qab no:
Kev lag luam boiler: phab ntsa dej boiler, superheater, economizer thiab lwm yam khoom tseem ceeb.
Cov khoom siv cua sov: cov kav dej condenser thiab cov evaporator hauv kev lag luam petrochemical.
Lub zog fais fab: cov kav dej xa hluav taws xob thiab cov tshuab pabcuam ntawm cov chaw tsim hluav taws xob thermal.
Kev siv nyiaj tsim nyog: Piv nrog cov kav hlau sib xyaw, ASTM SA210 GrA cov kav hlau carbon txo cov nqi yuav khoom thaum ua tau raws li qhov yuav tsum tau ua.
Kev muab khoom ruaj khov: Raws li cov khoom siv dav dav ntawm lub boiler, cov khoom lag luam hauv khw txaus thiab lub voj voog xa khoom luv luv.
Peb muab kev txiav tshwj xeeb, kev sim tsis ua puas tsuaj (UT/RT), daim ntawv qhia txog cov khoom siv thiab lwm yam kev pabcuam rau ASTM SA210 GrA cov kav hlau tsis muaj seamless, thiab txhawb kev xa khoom thoob ntiaj teb.
ASTM SA210 Qib ACov yeeb nkab carbon steel seamless tau dhau los ua cov khoom lag luam tseem ceeb hauv kev lag luam boilers thiab cov khoom siv hloov pauv cua sov vim nws qhov kev ua tau zoo ruaj khov thiab kev lag luam. Yog tias koj xav tau cov kev ntsuas kev siv tshuab lossis cov lus hais, thov hu rau peb pab neeg tshaj lij!
