Cov nroog niaj hnub no tau nce zuj zus los siv lub tswv yim ntawm kev siv hluav taws xob hauv nroog (tseem hu ua cov khoom siv hluav taws xob lossis cov yeeb nkab racks) los ua tsev ntau yam kav dej hauv nroog (dej, roj, hluav taws xob, kev sib txuas lus, cua sov) hauv qhov chaw nruab nrab hauv av. Txoj hauv kev no txhim kho kev zoo nkauj hauv nroog, txhim kho kev ua haujlwm ntawm kev saib xyuas, thiab tiv thaiv kev taug kev nquag. Nyob rau hauv cov kev sib txuas hauv av no, kev xaiv cov khoom siv muaj zog thiab txhim khu kev qha yog qhov tseem ceeb. Longitudinally Submerged Arc Welded (LSAW) steel kav tau tshwm sim raws li qhov kev xaiv zoo tshaj plaws rau cov txheej txheem tseem ceeb hauv cov tunnels. Tab sis yog vim li cas LSAW steel kav yog qhov nyiam cov qauv siv rau kev siv hluav taws xob hauv nroog niaj hnub no, thiab lawv muaj qhov tshwj xeeb zoo li cas hauv daim ntawv thov no? Hebei Huayang Steel Pipe Co., Ltd., tus kws tshaj lij hauv loj - txoj kab uas hla steel yeeb nkab raug tsim, delves rau hauv cov laj thawj tom qab qhov kev nyiam no loj hlob.
Qhov Kev Xav Tau Ntawm Cov Khoom Siv Hauv Nroog Niaj Hnub No
Kev siv hluav taws xob hauv nroog yog tsim los rau lub neej ntev thiab kev ua haujlwm, ntsib ntau yam teeb meem tseem ceeb:
•High Structural Loads: Tunnels yuav tsum tiv taus lub ntiaj teb siab, tsheb thauj khoom los ntawm saum toj no, thiab qhov hnyav ntawm ntau yam khoom siv hluav taws xob uas lawv muaj.
•Space Constraints: Kev siv tau zoo ntawm qhov chaw hauv av yog qhov tseem ceeb, yuav tsum muaj cov khoom siv uas muaj lub zog siab - rau - ntim piv.
• Lub neej ua haujlwm ntev: Cov tunnels no tau tsim los siv tau ntau xyoo lawm, xav tau cov khoom siv nrog kev ua haujlwm zoo thiab ua haujlwm tsis zoo.
•Seismic Resistance: Hauv ntau thaj chaw hauv nroog, kev tsim kho vaj tse yuav tsum raug tsim los tiv thaiv seismic yam tsis muaj kev puas tsuaj loj.
• Kev Tswj Corrosion: Ib puag ncig hauv av, muaj peev xwm muaj cov av noo thiab cov av sib txawv, yuav tsum muaj kev tiv thaiv corrosion zoo.
• Yooj yim ntawm kev txhim kho: Txawm hais tias lawv qhov nyuaj, kev tsim kho kev ua haujlwm yog qhov tseem ceeb kom txo qis kev cuam tshuam rau lub neej hauv nroog.
LSAW Steel Pipes: Engineered for Urban Resilience
LSAW steel kav muaj ib qho kev sib xyaw ua ke ntawm cov khoom uas ua rau lawv zoo tagnrho rau cov qauv kev xav tau ntawm kev siv hluav taws xob hauv nroog:
1. Superior Structural Strength thiab Load-Bearing Capacity
• Loj Diameter thiab Hnyav Phab Ntsa Thickness: LSAW kav yuav raug tsim nyob rau hauv loj heev diameters (txog 1422mm los yog ntau tshaj) thiab muaj ntau yam phab ntsa thicknesses. Qhov no tso cai rau lawv los ua cov kev txhawb nqa tseem ceeb hauv cov txheej txheem, pawg hauv paus, lossis txawm tias yog cov kav dej loj rau cov kab dej loj lossis cov pa roj uas tseem ua rau lub qhov dej ntawm cov qauv kev ncaj ncees.
•High Steel Qib: Ua los ntawm siab- lub zog steel daim hlau (xws li API 5L X60, X70, X80), LSAW kav muab cov txiaj ntsig zoo thiab lub zog tensile, ua rau lawv tuaj yeem tiv taus qhov hnyav thiab zoo li qub.
• Cov khoom tsis sib xws: Cov txheej txheem tsim khoom ua kom cov khoom siv sib xyaw ua ke thoob plaws hauv cov yeeb nkab lub cev, suav nrog cov vuam seam, uas yog qhov tseem ceeb rau kev ua tau zoo ntawm cov qauv.
2. Zoo heev Seismic Performance
•Ductility: High-LSAW kav dej muaj qhov zoo ductility, txhais tau tias lawv tuaj yeem deform loj hauv kev ntxhov siab ua ntej tawg. Qhov no yog ib qho khoom tseem ceeb rau kev tsim seismic, tso cai rau cov qauv kom nqus av qeeg zog yam tsis muaj kev sib tsoo tam sim ntawd.
• Cov kev sib txuas muaj zog: LSAW cov kav dej tuaj yeem yooj yim welded lossis bolted rau lwm yam qauv, tsim kom muaj kev sib txuas zoo, uas yog qhov tseem ceeb rau kev tiv thaiv seismic.
3. Durability thiab ntev kev pab cuam lub neej
•Corrosion Resistance: Thaum cov hlau raug corrosion, cov kav dej LSAW tuaj yeem tiv thaiv tau zoo nrog cov txheej txheem sab nraud (xws li, 3LPE, FBE) thiab cov hlua sab hauv. Cov txheej txheem no yog qhov tseem ceeb rau kev ua kom lub sijhawm ntev - kev ncaj ncees ntawm cov kav dej hauv qhov chaw ntub dej thiab muaj feem cuam tshuam rau qhov chaw hauv av.
•Resistance to External Damage: Lub cev muaj zog ntawm LSAW kav dej muab kev tiv thaiv rau sab nraud kev puas tsuaj los ntawm kev txav hauv av los yog kev puas tsuaj nyob rau hauv lub qhov.
4. Kev tsim khoom Precision thiab kev ruaj ntseg zoo
•Tight Dimensional Tolerances: LSAW cov kav dej yog tsim los kom nruj me ntsis kam rau ua, ua kom haum haum- thaum lub sij hawm tsim kho thiab txo qis kev ntxhov siab hauv cov qauv sib dhos.
•Extensive NDT: Cov txheej txheem tsim khoom suav nrog kev tsis zoo -Kev Ntsuas Kev Puas Tsuaj (NDT) ntawm cov vuam seam thiab cov yeeb nkab lub cev, lav qhov tsis muaj qhov tsis xws luag thiab ua kom cov qauv zoo tshaj plaws.
5. Versatility nyob rau hauv daim ntawv thov
LSAW cov kav dej tuaj yeem siv tau rau ntau lub luag haujlwm hauv nroog qhov chaw siv hluav taws xob:
•Primary Structural Columns/Piles: Txhawb nqa lub qhov taub nws tus kheej.
• Cov Khoom Siv Hluav Taws Xob Loj Loj: thauj cov dej ntau, roj, lossis dej phwj tuaj, thaum tseem ua haujlwm ua cov tswv cuab.
• Yeeb Nkab Racks thiab Kev Txhawb Nqa: Fabricated rau hauv cov thav duab muaj zog los txhawb cov kab hluav taws xob me me.
•Ventilation Shafts: Muab - txoj kab uas hla loj rau cua ncig.
