1. Nqe Lus Nug: Koj ua li cas kom ntseeg tau qhov kev ncaj ncees thiab lub zog ntawm cov vuam seam hauv koj cov kav dej ERW?
Teb:Weld kev ncaj ncees yog peb qhov tseem ceeb tshaj plaws. Peb ntiav ntau- txheej txheem kev ruaj ntseg zoo. Ua ntej, thaum lub sijhawm tsim khoom, peb siv lub xeev- ntawm--art high- vuam zaus nrog kev tswj nruj tshaj qhov kub thiab txias los ua kom zoo dua cov qauv ntawm cov vuam. Thib ob, peb ua 100% Tsis yog-Kev Ntsuas Kev Ua Phem (NDT) siv online Ultrasonic Tester (UT) lossis Eddy Current Tester. Thaum kawg, rau qhov kev txiav txim tseem ceeb, peb ua cov kev ntsuam xyuas kev puas tsuaj xws li Flattening, Flare, thiab Guided Bend tests ntawm cov qauv los ntawm txhua qhov cua sov kom lub cev siv tau lub zog weld tiv thaiv lub hauv paus hlau.
2. Lo lus nug: Dab tsi tsis yog -Kev Ntsuas Kev Ntsuas (NDT) koj siv los txheeb xyuas qhov tsis xws luag?
Teb:Txhawm rau lav qhov tsis muaj qhov tsis zoo, peb siv kev sib txuas ntawm online NDT txoj kev. Feem ntau, peb siv ib qhoUltrasonic Tester (UT)txhawm rau txheeb xyuas tag nrho cov vuam seam thiab Heat Afected Zone (HAZ) rau kev cuam tshuam sab hauv. Nyob rau hauv parallel, peb siv ib tugEddy Tam sim no Tester (ET)txhawm rau txheeb xyuas qhov chaw thiab ze ntawm - defects. Rau siab - cov kav dej siab, peb kuj muab cov kev xaiv ntawmTag Nrho Lub Cev Ultrasonic Testthaum thov.
3. Nqe Lus Nug: Koj puas ua Hydrostatic Testing ntawm txhua lub yeeb nkab? Cov kev ntsuas ntsuas yog dab tsi?
Teb:Yog lawm, kiag li . 100% ntawm peb cov kav dej ERW tau dhau los ua cov txheej txheem Hydrostatic Testing nruj raws li kev kuaj zaum kawg rau kev xau thiab vuam lub zog. Cov yeeb nkab tau ntim nrog dej, thiab lub siab sab hauv yog siv raws li tus qauv teev tseg (xws li API 5L lossis ASTM A53). Lub siab yog tuav rau qhov tsawg kawg nkaus ntawm 5 mus rau 10 vib nas this kom ntseeg tau tias tsis muaj qhov poob siab los yog pom pom. Peb tuaj yeem muab cov ntawv qhia txog kev ntsuas hydrostatic nrog rau cov nqi tshwj xeeb uas tau thov, uas yog xam raws li cov yeeb nkab qhov ntev thiab qib.
4. Lo lus nug: Koj yuav tswj cov "Flash" (weld hlaws) hauv cov yeeb nkab li cas? Nws puas raug tshem tawm?
Teb:Kev tswj ntawm lub hauv paus weld flash (cov hlau tshaj tawm thaum vuam) yog qhov tseem ceeb rau kev khiav hauj lwm zoo. Hauv peb cov txheej txheem ntau lawm, lub flash sab nraud yog ib txwm trimmed flush. Rau sab hauv flash, peb muaj ob txoj kev xaiv:
Txheem:Internal flash yog tswj tab sis tsis tshem tawm (ib tug me me hlaws dai).
Internal Flash Trimmed (IFT):Peb tuaj yeem nruab cov cuab yeej los txiav cov hlaws sab hauv cov hlaws mus rau qhov tsis tshua muaj qhov profile, lossis yaug nrog cov yeeb nkab phab ntsa. Qhov no yog qhov pom zoo rau cov ntawv thov uas yuav siv cov npua tu sab hauv lossis qhov chaw txaus siab tshaj plaws. Thov qhia yog tias koj xav tau IFT.
5. Lo lus nug: Dab tsi yog "Huab Hluav Taws Xob Hluav Taws Xob" (HAZ) thiab vim li cas nws tseem ceeb hauv cov kav dej ERW?
Teb:Lub Heat Afected Zone (HAZ) yog thaj tsam ntawm lub hauv paus hlau nyob ib sab ntawm lub vuam uas muaj nws cov microstructure thiab txhua yam khoom hloov pauv los ntawm cov cua sov ntawm vuam. Hauv ERW cov kav dej, qhov nqaim HAZ yog ib qho cim ntawm qhov zoo, muaj txiaj ntsig zoo. HAZ dav tuaj yeem qhia tau tias muaj cua sov ntau dhau, uas yuav ua rau cov yeeb nkab nkig ntau dua hauv cheeb tsam ntawd. Peb lub siab - cov txheej txheem vuam zaus raug tswj xyuas kom txo qis HAZ, kom ntseeg tau tias cov khoom siv kho tshuab thoob plaws thaj tsam weld nyob ze li sai tau rau cov niam txiv hlau, uas peb txheeb xyuas los ntawm peb cov txheej txheem kuaj hardness.
