Khoom Description
ASTM A106 yog tus qauv tshwj xeeb rau seamless carbon steel yeeb nkab rau siab -kev pabcuam kub, tsim los ntawm ASTM International. Nws yog arguably cov ntaub ntawv dav dav tshaj plaws hauv cov khoom siv hauv refinery, petrochemical, thiab cov kav dej tsim hluav taws xob. Cov kev qhia tshwj xeeb npog peb qib - B, thiab C - nrogQib Byog siv ntau tshaj plaws, muab qhov zoo tshaj qhov sib npaug ntawm lub zog thiab weldability rau kev thov siab - kub, siab - kev siv siab.
Qhov Zoo Tshaj Plaws
100% Seamless Tsim
ASTM A106 yog aseamless -tsuas yogspecification. Cov kav dej yog tsim los ntawm cov khoom siv puag ncig steel billets los ntawm cua sov, perforation, thiab kub- dov lossis txias- txheej txheem kos duab, ua rau cov phab ntsa tuab tuab thiab tsis muaj qhov tsis muaj qhov sib txuas. Cov qauv seamless no tshem tawm qhov kev pheej hmoo ntawm kev xau lossis tsis ua haujlwm ntawm cov pob qij txha welded, ua rau nws tseem ceeb rau boiler, superheater, thiab siab - cov kua dej siab.
Superior High -Tsub Ua Haujlwm
Qib B cov kav dej ntseeg tau ua haujlwm ntawm qhov kev pabcuam txuas ntxiv mus txog kwv yees li427℃(800℃F). Lawv yog cov zoo tagnrho rau siab - siab boiler daim ntaub ntawv (ua hauj lwm siab feem ntau tshaj 9.8 MPa, kev khiav hauj lwm kub ntawm 450℃thiab 650 degree), suav nrog superheater hlab, reheater raj, lub ntsiab chav kav, thiab economizer Cheebtsam.
Reliable Mechanical Properties
| Qib | Tensile zog (MPa) | Yield zog (MPa) | Elongation (%) |
|---|---|---|---|
| Qib B | Ntau dua lossis sib npaug li 415 | Ntau dua lossis sib npaug li 240 | 30 (Longitudinal) |
| Qib C | Ntau dua lossis sib npaug rau 485 | Ntau dua lossis sib npaug li 275 | 30 (Longitudinal) |
Strict Chemical Composition Control
| Lub ntsiab | Qib B | Qib C |
|---|---|---|
| Carbon (C) Tsawg dua lossis sib npaug | 0.30% | 0.35% |
| Manganese (Mn) | 0.29–1.06% | 0.29–1.06% |
| Silicon (Si) Ntau dua lossis sib npaug | 0.10% | 0.10% |
| Phosphorus/Sulfur (P/S) Tsawg dua los yog sib npaug | 0.035% | 0.035% |
Lus Cim: Tag nrho cov khoom seem (Cr, Cu, Mo, Ni, V) yuav tsum tsis pub tshaj 1%.
Tej kev siv
● Fais Fab Tsim Boilers: Superheater tubes, reheater tubes, economizer raj, dej phab ntsa raj, thiab headers.
● Refinery & Petrochemical: High-Cov txheej txheem kub ntawm cov kav dej, cov kav dej, thiab cov khoom siv hluav taws xob sib txuas.
● Cov kav dej siabCov txheej txheem piping rau ASME B31.1 thiab B31.3 specifications.
Kev Xa Khoom
Kev tsim khoom: Kub-ua tiav (kub- dov / nthuav dav) lossis txias- kos (txias- dov).
Kev kho cua sov: Txias-cov kav dej yuav tsum zoo li qub los yog kev ntxhov siab-relieved.
Kev kho saum npoo: Dub pleev xim los yog lwm yam los tiv thaiv -corrosion txheej raws li cov neeg siv khoom xav tau.
