SA387Gr11CL2 siab lub nkoj steel phaj nthuav dav qhia
SA387Gr11CL2 yog cov phaj steel feem ntau siv rau cov hlab ntsha siab, feem ntau yog siv hauv kev tsim cov khoom kub thiab siab siab hauv cov roj av, tshuaj lom neeg kev lag luam, chaw nres tsheb fais fab thiab lwm yam lag luam. Cov phaj hlau no muaj cov cua kub zoo heev, tiv thaiv corrosion thiab txhua yam khoom, yog li nws tau siv dav hauv kev lag luam.
Tshuaj muaj pes tsawg leeg ntawm SA387Gr11CL2 steel phaj
Cov tshuaj muaj pes tsawg leeg ntawm SA387Gr11CL2 steel phaj mas suav nrog carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum thiab lwm yam alloying ntsiab. Ntawm lawv, qhov sib ntxiv ntawm chromium thiab molybdenum txhim kho cov cua sov thiab corrosion kuj ntawm steel phaj, yog li nws muaj peev xwm tswj tau qhov kev ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig corrosion. Tsis tas li ntawd, los ntawm kev tswj cov ntsiab lus ntawm cov pa roj carbon, silicon, manganese thiab lwm yam khoom, cov khoom siv kho tshuab thiab kev ua haujlwm ntawm cov phaj hlau tuaj yeem ua tau zoo ntxiv.
SA387Gr11CL2 siab nkoj steel phaj ceev faj
1. Kev xaiv cov khoom tsim nyog:
Raws li kev siv ib puag ncig thiab cov khoom siv, xaiv qhov tsim nyog SA387Gr11CL2 steel phaj qib, specification thiab qib zoo. Nyob rau tib lub sijhawm, ua tib zoo saib xyuas seb qhov zoo li zoo li cas, qhov tseeb qhov tseeb thiab cov tshuaj muaj pes tsawg leeg ntawm cov phaj steel ua tau raws li qhov yuav tsum tau ua.
2. Txuj kev ua:
Hauv kev tsim cov txheej txheem, cov txheej txheem sib xws thiab cov txheej txheem kev nyab xeeb yuav tsum tau ua raws li kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov phaj steel. Tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem tseem ceeb xws li kev txiav, vuam thiab kev kho cua sov, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj cov txheej txheem thiab cov txheej txheem kev khiav hauj lwm kom tsis txhob muaj qhov tsis xws luag thiab kev puas tsuaj.
3. Kev tshuaj xyuas tsis tu ncua:
Nyob rau hauv tus txheej txheem ntawm kev siv, nws yog ib qhov tsim nyog los xyuas thiab tswj cov cuab yeej tsis tu ncua kom pom thiab daws cov teeb meem tshwm sim raws sijhawm. Tshwj xeeb tshaj yog rau cov khoom siv tseem ceeb xws li cov hlab ntsha kub thiab kub siab, kev kuaj tsis muaj kev puas tsuaj, kev ntsuas siab thiab kev ntsuas kev nyab xeeb yuav tsum tau ua tsis tu ncua los xyuas kom meej tias lawv muaj kev nyab xeeb thiab txhim khu kev qha.
4. Tsim nyog siv:
Thaum siv cov khoom siv, nws yog ib qho tsim nyog yuav tsum tau ua raws li cov txheej txheem kev khiav hauj lwm thiab kev ruaj ntseg kom tsis txhob siv cov kev coj cwj pwm tsis zoo xws li overload, overpressure, thiab overtemperature. Nyob rau tib lub sijhawm, ua tib zoo saib xyuas thiab saib xyuas cov khoom siv kom ntev nws lub neej kev pabcuam thiab kev ua haujlwm ruaj khov.
