High-Frequency Welded (HFW) steel kav sawv cev rau kev hloov pauv hloov pauv hauv hluav taws xob tiv thaiv vuam (ERW) thev naus laus zis, muab cov khoom zoo tshaj, txhim kho kev ntseeg tau, thiab tus nqi- ua tau zoo rau ntau yam kev siv. Tsis zoo li cov kav dej ERW ib txwm muaj, HFW siv siab - zaus tam sim no los ua kom muaj cua sov, ua rau muaj qhov tseeb dua thiab huv dua weld seam nrog cov cua sov me me- thaj chaw cuam tshuam (HAZ). Cov txheej txheem tsim khoom siab tshaj no ua kom muaj cov khoom siv tshwj xeeb thiab kev ua haujlwm zoo ib yam, ua rau HFW kav dej yog qhov kev xaiv zoo tshaj plaws rau cov phiaj xwm tseem ceeb, suav nrog cov roj thiab cov kav dej, kev siv cov qauv, thiab kev xa dej. Hebei Huayang Steel Yeeb Nkab Co., Ltd., ib tug ua lag luam ntawm HFW steel kav, delves rau hauv intricate ntau lawm txheej txheem thiab inherent zoo zoo uas teem HFW kav sib nrug.
Nkag siab txog HFW Production Process
Kev tsim khoom ntawm HFW steel kav yog kev ua haujlwm tas mus li, tsis siv neeg uas hloov cov hlau coils rau hauv cov kav dej tiav nrog kev ua tau zoo thiab qhov tseeb. Cov kauj ruam tseem ceeb suav nrog:
1. Kev npaj coil
Cov txheej txheem pib nrog uncoiling loj steel strips (coils). Cov kab txaij no dhau los ua ntug trimming kom ntseeg tau tias qhov dav dav thiab cov npoo huv si, uas yog qhov tseem ceeb rau kev ua haujlwm siab - vuam zoo. Qhov kawg ntawm cov coils successive ces welded ua ke los tsim ib tug nruam sawb, cia rau uninterrupted ntau lawm.
2. kev tsim
Lub nruam steel sawb yog pub los ntawm kev sib sau ua cov menyuam. Cov chais no tau ua kom zoo li lub tiaj tiaj mus rau hauv qhov qhib -seam cylindrical raj. Qhov tseeb ntawm qhov txheej txheem no yog qhov tseem ceeb, vim nws txiav txim siab qhov tseeb ntawm cov yeeb nkab txoj kab uas hla thiab roundness, thiab xyuas kom meej cov npoo yog zoo kawg nkaus haum rau vuam.
3. Siab -Frequency Induction Vuam
Qhov no yog qhov tseem ceeb ntawm HFW txheej txheem. Raws li lub raj tsim los ze rau qhov vuam taw tes, siab - zaus hloov tam sim no (feem ntau yog 100 kHz txog 700 kHz) yog induced rau hauv cov npoo ntawm qhib seam. Lub siab - zaus tam sim no ntws raws cov npoo, tsom mus rau qhov kub thiab txias ntawm qhov chaw yuav tsum tau koom nrog. Qhov cua kub ceev thiab hauv cheeb tsam no coj cov npoo mus rau hauv lub xeev yas (hauv qab lub ntsiab lus melting). Ib txhij, nyem cov menyuam siv lub siab loj, forging cov npoo rhuab ua ke los ua ib qho khoom siv - xeev weld. Cov khoom tsis huv thiab oxidized raug tshem tawm ntawm thaj chaw weld, tsim ib lub teeb uas tam sim ntawd txiav tawm ob qho tib si sab hauv thiab sab nraud.
4. Sizing thiab straightening
Tom qab vuam, cov yeeb nkab dhau los ntawm qhov sib txawv ntawm cov chais uas tau kho nws txoj kab uas hla thiab xyuas kom meej. Nws tom qab ntawd ua kom ncaj kom tshem tawm txhua qhov curvature thiab ua tiav cov kev xav tau ncaj nraim.
5. Tsis yog -Kev Ntsuam Xyuas Kev Puas Tsuaj (NDT)
Thoob plaws hauv thiab tom qab cov txheej txheem vuam, cov txheej txheem NDT nruj yog ua haujlwm los xyuas kom muaj kev ncaj ncees. Qhov no feem ntau suav nrog kev kuaj ultrasonic (UT) txhawm rau txheeb xyuas qhov tsis zoo sab hauv thiab sab nraud, thiab qee zaum eddy kev sim tam sim no. Cov kev sim no tau ua tiav hauv online, muab cov lus qhia tiag tiag - lub sijhawm thiab ua kom ntseeg tau tias tsuas yog muaj qhov tsis zoo - cov kav dej dawb xwb.
6. Kev txiav, xaus, thiab txheej
Cov yeeb nkab txuas ntxiv yog txiav rau hauv qhov ntev. Cov yeeb nkab kawg yog ces beveled los yog threaded raws li tus neeg yuav tsum tau muaj. Thaum kawg, nyob ntawm daim ntawv thov, cov kav dej yuav dhau los ua txheej txheem txheej txheem sab hauv thiab sab nraud (xws li 3LPE, FBE, kua roj vanish) txhawm rau txhim kho corrosion kuj.
Superior Quality Advantages of HFW Steel Pipes
Cov txheej txheem tsim HFW muab ntau qhov zoo sib xws uas ua rau cov kav dej no txhim khu kev qha thiab tsim nyog rau kev thov.
Thaum tshav kub kub tsawg -Teb chaws cuam tshuam (HAZ)
Ib qho txiaj ntsig tseem ceeb tshaj plaws ntawm HFW yog qhov tsis tshua muaj neeg nyob thiab cua sov ceev. Qhov no ua rau HAZ nqaim heev, uas txo qis kev hloov pauv mus rau microstructure thiab txhua yam khoom ntawm cov hlau uas nyob ib sab ntawm lub vuam. HAZ me me txhais tau hais tias cov yeeb nkab khaws cia ntau dua ntawm nws cov khoom qub muaj zog thiab toughness, txo qhov kev pheej hmoo ntawm nkig tawg.
Muaj zog thiab Ductile Weld Seam
Lub forging kev txiav txim ntawm qhov nyem chais, ua ke nrog cov cua kub zoo, tsim ib qho kev sib txuas uas feem ntau muaj zog thiab muaj zog dua li cov khoom siv niam txiv. Cov khoom siv- lub xeev vuam txheej txheem zam melting, uas tshem tawm cov teeb meem xws li solidification cracking thiab porosity feem ntau txuam nrog fusion vuam txoj kev. Qhov no ua rau muaj kev sib koom ua ke thiab muaj zog.
Zoo heev Surface Finish thiab Dimensional raug
Qhov nruam thiab automated xwm ntawm HFW ntau lawm, ua ke nrog kev sib sau ua ke thiab qhov loj me, ua rau cov kav dej nrog zoo heev sab nrauv thiab sab hauv nto tiav. Dimensional raug, suav nrog zoo ib yam li sab nraud txoj kab uas hla, phab ntsa thickness, thiab ncaj, kuj yog ib tug cim ntawm HFW kav dej, yooj yim installation thiab kev twb kev txuas.
Tus nqi -Kev ua tau zoo thiab kev ua tau zoo
Kev ua haujlwm siab ceev thiab kev ua haujlwm tsis tu ncua ntawm HFW kab ua rau nws muaj txiaj ntsig zoo thiab tus nqi -txoj kev zoo rau kev tsim cov kav hlau. Cov khoom siv tsawg tsawg thiab txo qhov xav tau rau kev xa tawm -weld kho cua sov (vim HAZ me me) ntxiv rau nws cov txiaj ntsig kev lag luam.
Versatility nyob rau hauv cov khoom qib
HFW thev naus laus zis tuaj yeem siv rau ntau hom hlau, los ntawm cov qauv hlau dav dav mus rau siab -lub zog qis- alloy (HSLA) steels, tso cai rau kev tsim cov kav dej raws li cov kev xav tau tshwj xeeb, xws li cov siab - roj thiab roj xa mus.
