Peb feem ntau hnov txog cov raj xa dej, cov raj xa dej nominal, cov raj xa dej kua, cov raj ntsuas, cov raj metric, cov raj twin ferrules, cov raj seamless, cov raj BA, cov raj precision dov, thiab lwm yam. Muaj ntau lub npe, lub npe txheem yog leej twg? Cia peb piav qhia txog cov raj stainless hlau hauv qab no.
Yuav kom nkag siab tias cov yeeb nkab hlau tsis xeb hu ua li cas thiab cais ua pawg li cas, thawj qhov thiab lub tswv yim tsis meej pem tshaj plaws yog kom meej meej:cov raj xa dejthiab yeeb nkab. Ob leeg raj thiab yeeb nkab txhais tau tias yeeb nkab hauv lus Askiv, thiab tsis muaj kev txhais lus Suav sib xws. Yog li qhov txawv ntawm lawv yog dab tsi?
1. Ua ntej, cov txheej txheem sawv cev sib txawv: cov raj xa dej yog sawv cev los ntawm sab nraud txoj kab uas hla thiab phab ntsa tuab, thaum cov yeeb nkab raj yog sawv cev los ntawm NPS (nominal yeeb nkab loj) nominal txoj kab uas hla thiab daim ntawv teev sijhawm No. phab ntsa tuab tus lej.
2. Cov qauv sib txawv: Tus qauv rau cov kav dej yog ASTM A269 thiab ASTM A213, thaum tus qauv rau cov kav dej yog ASTM A312.
3. Kev kam rau siab sib txawv: Qhov ntau ntawm kev kam rau siab ntawm cov raj yog me dua li ntawm cov yeeb nkab. Hauv kev xam qhov siab, cov raj feem ntau tuaj yeem sawv cev rau qhov siab (psi), thaum cov yeeb nkab feem ntau yog sawv cev los ntawm PN nominal siab.
4. Cov xeev sib txawv: lub raj yog nyob rau hauv ib qho annealed xeev, thiab tsis muaj qhov yuav tsum tau rau lub yeeb nkab, uas yog vim li cas lub raj tuaj yeem khoov ncaj qha, thaum lub yeeb nkab yuav tsum tau txuas nrog lub luj tshib.
5. Cov ntawv thov sib txawv: Cov raj muaj ntau yam lus qhia, yog li nws feem ntau siv rau hauv cov txheej txheem ntsuas, thaum cov yeeb nkab muaj tsawg dua cov lus qhia thiab feem ntau siv rau hauv cov txheej txheem fais fab thiab cov txheej txheem.
Lub npe Suav uas tsim nyog rau "tubing" thiab "yeeb nkab" yog dab tsi? Peb ntseeg tias nws yog qhov tsim nyog dua los sib raug rau "txheej txheem yeeb nkab" thiab "cov yeeb nkab ntsuas". Qhov sib txawv no yog raws li kev siv thiab tseem yog qhov sib txawv tseem ceeb ntawm "tubing" thiab "yeeb nkab".
Lwm cov npe yooj yim dua los paub qhov txawv:
1. Los ntawm qhov kev xav ntawm kev tsim, cov kav dej vuam hu ua cov kav dej vuam, thaum cov kav dej tsim los ntawm kev dov thiab kos duab txias hu ua cov yeeb nkab tsis muaj qhov txuas. Cov yeeb nkab tsis muaj qhov txuas yuav tsum tau muab faib ua cov yeeb nkab tsis muaj qhov txuas thiab cov yeeb nkab tsis muaj qhov txuas raws li lawv qhov kev dov thiab kos duab txias.
2. BA raj, EP raj, kua qaub pickling raj, thiab polishing raj yog sib txawv raws li lawv qhov xwm txheej ntawm qhov chaw. BA raj yog hais txog qhov ci ntsa iab ntawm lub raj, EP raj yog hais txog electrochemical polishing ntawm lub raj, acid pickling raj yog hais txog kev tshem tawm ntawm cov txheej oxide los ntawm acid pickling passivation tom qab lub raj ua tiav, uas yog lub xeev yooj yim ntawm lub raj, thiab polishing raj yog hais txog kev kho mob polishing ntawm sab nraud ntawm lub raj.
3. Raws li cov kav dej kua thiab cov raj xa dej, lawv feem ntau hu ua sawv ntawm lub kaum sab xis ntawm kev siv.
4. Cov raj metric yog piv rau cov raj fractional, thiab lawv yog ib qho kev faib tawm hauv qab cov raj ntsuas. Cov raj fractional yog cov raj nrog cov kab uas hla thiab phab ntsa tuab ntsuas hauv cov chav fractional.
5. Cov yeeb nkab nominal yeej yog ib lub yeeb nkab, thiab lub tswv yim ntawm cov yeeb nkab nominal tuaj yeem pom hauv cov lus piav qhia ntxaws ntawm Hikelok lub tswv yim nominal.
Hikelok, ib lub chaw tsim khoom siv cov twj paj nruag thiab cov khoom siv.
