Txias Tsim A252 Qib 1 Welded Steel Yeeb Nkab Rau Cov Kav Dej Roj
ASTM A252 yog ib qho qauv yeeb nkab hlau uas tau tsim tsa zoo siv rau hauv cov ncej hauv paus, cov ncej choj, cov ncej pier thiab lwm yam kev ua haujlwm engineering. Cov yeeb nkab hlau no tau tsim los kom tiv taus qhov siab siab thiab tsim nyog rau kev siv hauv ntau qhov chaw nyuaj. Pebtxias tsim welded qauvCov kav dej roj yog tsim los ntawm A252 Qib 1 hlau, uas paub txog nws qhov kev ua tau zoo thiab lub zog.
Khoom Siv Kho Tshuab
| Qib 1 | Qib 2 | Qib 3 | |
| Yield Point los yog yield zog, min, Mpa (PSI) | 205 (30 000) | 240 (35 000) | 310 (45 000) |
| Lub zog tensile, min, Mpa (PSI) | 345 (50 000) | 415 (60 000) | 455 (66 0000) |
Peb txoj kev tsim cov kav hlau siv ob txoj kev vuam submerged arc, kom ntseeg tau tias muaj qib siab ntawm kev vuam cov kav hlau los ntawm sab hauv thiab sab nraud, tsim kom muaj kev sib txuas zoo. Qhov kawg yog cov khoom uas tiv taus xeb heev thiab haum rau ntau yam kev siv hauv kev lag luam thiab kev tsim kho.
Peb cov yeeb nkab roj uas tau vuam txias kuj tsim los ua kom tau raws li cov kev cai tshwj xeeb ntawm cov khoom siv kho tshuab uas tau teev tseg hauv tus qauv ASTM A252. Raws li tus qauv no, peb cov yeeb nkab hlau tau muab faib ua peb qib: Qib 1, Qib 2 thiab Qib 3, nrog rau txhua qib muab cov qib sib txawv ntawm lub zog thiab kev ruaj khov. Qhov no ua rau peb cov neeg siv khoom xaiv qib uas zoo tshaj plaws rau lawv cov kev siv thiab kev ua tau zoo.
Txawm siv ua cov ncej hauv paus rau ib qho project tsim kho lossis ua ib feem ntawm cov choj lossis pier pilings, peb cov kav hlau raug tsim los kom tiv taus cov teeb meem nyuaj tshaj plaws. Lawv xa cov kev ua tau zoo txhim khu kev qha thiab ruaj khov ntev, ua rau lawv zoo tagnrho rau ntau yam kev siv engineering thiab kev tsim kho.
Hauv kev xaus, peb cov qauv tsim welded txiascov kav roj, tsim los ntawm A252 Qib 1 hlau thiab tsim los ntawm kev siv ob chav submerged arc welding txoj kev, yog ib qho kev daws teeb meem txhim khu kev qha thiab zoo rau ntau yam kev siv. Cov kav hlau no ua raws li ASTM A252 cov qauv thiab tau tsim los ua kom tau raws li cov kev cai tshwj xeeb, xyuas kom meej tias lawv muab kev ua tau zoo tshaj plaws thiab kev ua haujlwm ntev. Xaiv peb cov kav hlau rau koj qhov project tom ntej thiab paub txog qhov sib txawv ntawm qhov zoo thiab kev ntseeg siab.
