Nrog rau kev nce qib ntawm kev loj hlob hauv nroog hauv Suav teb thiab kev ua kom zoo dua qub ntawm cov qauv siv hluav taws xob huv si, kev siv cov roj ntsha hauv nroog cov pa roj, kev siv hluav taws xob, thiab thaj chaw cua sov hauv tsev tau nthuav dav. Raws li cov txheej txheem tseem ceeb hauv cov tshuab xa hluav taws xob, cov kav xa hluav taws xob muaj cov kev xav tau siab heev rau kev nyab xeeb, kev sib khi, kev ruaj ntseg, thiab kev lag luam ntawm lawv cov ntaub ntawv.
Nyob rau hauv nruab nrab thiab qis- siab lub tshuab xa hluav taws xob, siab- zaus welded (HFW/ERW) steel kav, nrog rau lawv cov txheej txheem tsim khoom lag luam, zoo heev weld seam zoo, thiab tus nqi zoo-kev ua tau zoo, tau dhau los ua ib qho ntawm cov khoom siv yeeb nkab tseem ceeb hauv cov kav dej hauv nroog, cov kav dej kav dej, thiab cov kav dej.
1. Cov Ntsiab Lus Tseem Ceeb thiab Kev Tsim Nyog ntawm Siab -Frequency WeldedHlauCov kav dej
HFW/ERW steel kav feem ntau xa mus rau longitudinal welded steel kav uas tsim los siv lub siab - zaus kuj welding txheej txheem. Cov txheej txheem tsim khoom yuav txuas ntxiv khoov kub- dov steel strips rau hauv cov yeeb nkab zoo los ntawm lub tshuab tsim. High- zaus tam sim no yog siv rau cov npoo ntawm cov yeeb nkab, tsim cov nyhuv ntawm daim tawv nqaij thiab cov nyhuv sib thooj, uas ua rau kub ceev cov npoo welded mus rau lub xeev molten. Nyob rau hauv qhov kev txiav txim ntawm nyem chais, khoom- xeev vuam tshwm sim, uas ua rau ib tug nruam weld seam.
This process features fast welding speed, a narrow heat-affected zone, a dense weld structure, and high dimensional accuracy, making it ideal for mass production and continuous manufacturing. High- cov kav dej ntau zaus tau siv dav hauv cov roj av, kev thauj dej, kev tsim vaj tsev, thiab kev tsim khoom siv tshuab.
2. Cov ntsiab lus tseem ceeb rau cov yeeb nkab steel kev ua tau zoo hauv cov kav xa hluav taws xob hluav taws xob
Raws li cov pa roj carbon monoxide yog cov khoom tawg yooj yim thiab tawg, nws txoj kev sib kis tau muaj kev ruaj ntseg ntau dua li cov kav dej zoo tib yam. Cov kev cai tseem ceeb rau cov kav xa hluav taws xob yog qhov tseem ceeb hauv cov hauv qab no:
- Zoo weld seam ceevlos tiv thaiv cov pa paug.
- Stable mechanical zoglos xyuas kom meej ntev -lub sij hawm siab- kev ua haujlwm bearing.
- Kev qaug zog zoolos tswj cov kev hloov pauv siab.
- Zoo heev corrosion kujhloov mus rau complex underground ib puag ncig.
- Txhim khu qhov tseeb qhov tseeblos xyuas kom meej qhov zoo thaum lub sij hawm ntawm - qhov chaw vuam.
Thaum lub sij hawm tsim cov txheej txheem, siab - zaus welded kav yuav raug rau ntau yam kev tswj kom zoo, xws li hauv internet weld seam soj ntsuam, tsis siv neeg vuam seam tshem tawm, kho cua sov, thiab qhov ntev calibration, uas muab ib tug ruaj khov thiab txhim khu kev qha daim ntawv thov lub hauv paus rau nruab nrab thiab qis - siab gasket systems.
3. Daim ntawv thov Scope ntawm High-Frequency WeldedHlauCov kav dej hauv Natural Gas Transmission Systems
Hauv cov tshuab hluav taws xob xa hluav taws xob, cov kav dej feem ntau muab faib ua siab - siab, nruab nrab- siab, thiab qis- cov kav dej siab, thiab kev xaiv cov kav hlau sib txawv nyob ntawm qhov ntsuas siab.
1. Lub Nroog Gas nruab nrab thiab qis -Kev Sib Txuas Sib Txuas Sib Txuas
Hauv nroog gas networks yog ib qhov chaw siv dav tshaj plaws rau HFW / ERW steel kav, feem ntau yog siv hauv cov kav dej hauv tsev, cov pa roj hauv txoj kev, thiab kev lag luam thiab kev lag luam roj. Cov kav dej no feem ntau muaj qhov siab qis dua 0.4 MPa, yuav tsum muaj qhov siab nruab nrab -cov kabmob muaj peev xwm tab sis xav tau siab rau cov vuam seam cua nruj thiab tiv thaiv- kev ua haujlwm corrosion. HFW/ERW steel kav, nrog rau lawv cov weld seams du, du sab hauv phab ntsa, thiab cov pa roj zoo heev - nruj, ua kom muaj kev nyab xeeb ntawm kev xa roj.
2. Industrial Park Gas Transmission Pipelines
Cov kav dej muaj roj siv tau los muab cov roj roj rau cov lag luam hauv kev lag luam xws li tshuaj lom neeg, metallurgy, cov khoom siv hauv tsev, thiab hluav taws xob, nrog rau cov kev xav tau siab dua rau kev ruaj ntseg thiab ntev - kev ntseeg tau. HFW / ERW steel kav, nrog rau sab hauv thiab sab nraud corrosion tiv thaiv txheej txheej, yog tsim rau underground los yog pipeline gallery installation thiab ua tau raws li qhov yuav tsum tau rau kev ua hauj lwm tas mus li nyob rau hauv industrial gas kis ib puag ncig.
3. Natural Gas Branch thiab Regional Transmission Pipelines
Hauv cov txheej txheem txuas ntxiv cov kav xa hluav taws xob tseem ceeb rau cov nroog, cov chaw ua si, thiab cov nroog, cov kav xa dej feem ntau siv cov kav dej nruab nrab - txoj kab uas hla. HFW / ERW steel kav muab kev lag luam zoo hauv daim teb no. Los ntawm kev xaiv cov qib steel, phab ntsa tuab, thiab tiv thaiv - qauv corrosion, HFW / ERW steel kav tau zoo- haum rau cov dej xa hluav taws xob hauv cheeb tsam.
4. Technical Advantages of High-Frequency WeldedHlauCov kav dej hauv Gas Engineering
Piv rau seamless steel kav thiab lwm yam welded yeeb nkab hom, HFW / ERW steel kav muaj ntau yam zoo nyob rau hauv gas kis engineering.
- ruaj khov weld seam zoo: High- vuam zaus yog ib qho khoom siv- lub xeev vuam txheej txheem, qhov twg cov hlau vuam cov qauv zoo ib yam thiab tuab, qhov kub ntawm qhov chaw raug cuam tshuam yog nqaim, thiab lub vuam seam lub zog yog ze rau ntawm cov khoom siv hauv paus.
