Cov lus nug nquag
Q: Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm cov kav dej txias txias dua cov kub dov?
A: Kev kos duab txias muab nruj dua qhov ntev ntev, cov phab ntsa tuab tuab, qhov zoo ntawm qhov zoo thiab ua kom lub zog muaj zog, uas yog qhov tseem ceeb rau kev sib txuas tsis muaj kev sib txuas rau hydraulic fittings.
Q: Puas yog kos duab txias txiav txim siab qhov siab tshaj plaws kev khiav hauj lwm ntawm cov yeeb nkab?
A: Tsis yog. Kev kos duab txias ua kom cov duab geometric raug thiab qhov zoo ntawm qhov chaw. Kev tso cai ua haujlwm siab yog xam raws li qib steel, txheej txheej, phab ntsa thickness, kev ua haujlwm kub, ib puag ncig thiab kev nyab xeeb.
Q: Dab tsi yog qhov kev xa khoom pom zoo rau cov kab hydraulic uas yuav tsum tau khoov?
A: +N (Normalized / NBK) mob yog pom zoo raws li nws muab kev pom zoo ductility, nplua grain qauv thiab siab toughness yuav tsum tau rau txias dabtsi yog khoov thiab flaring.
Q: Puas yog kev tshuaj xyuas thib peb (TPI) ua ntej ua zaub mov xa tuaj?
A: Yog. Kev tshuaj xyuas thib peb (SGS, BV, TUV, thiab lwm yam) tuaj yeem npaj los xyuas cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev thiab NDT raws li EN 10204 3.2.
Q: Dab tsi yog cov ntaub ntawv tsawg kawg nkaus uas xav tau kom tau txais RFQ?
A: Thov muab sab nraud txoj kab uas hla (OD), phab ntsa thickness (WT), qib steel, tus qauv, kev xa khoom (+ N / + SR), ntev, qhov ntau thiab tshwj xeeb kuaj lossis cov ntaub ntawv xav tau.
