Hauv kev tsim kho cov phiaj xwm loj xws li txuas hniav, skyscrapers, offshore platforms, thiab chaw nres nkoj, lub hauv paus yog qhov tseem ceeb tshaj plaws. Cov qauv no feem ntau xav tau qhov sib sib zog nqus, siab - lub hauv paus muaj peev xwm muaj peev xwm tiv taus cov kab nrib pleb loj, lub zog sab nraud, thiab cov av nyuaj. Ntawm cov khoom siv ntau yam siv rau hauv lub hauv paus piling, Longitudinally Submerged Arc Welded (LSAW) steel kav tau tshwm sim tsis tu ncua raws li qhov kev xaiv rau hnyav - lub luag haujlwm structural piling. Tab sis yog vim li cas LSAW steel yeeb nkab yog cov khoom siv rau hnyav -cov haujlwm ua haujlwm piling? Hebei Huayang Steel Pipe Co., Ltd., ib lub chaw tsim khoom tshwj xeeb ntawm LSAW kav, tshuaj xyuas kev tsim vaj tsev thiab kev ua tau zoo uas ua rau cov kav dej LSAW tseem ceeb rau cov hauv paus tseem ceeb no.
Qhov Kev Thov Heavy-Lub Luag Haujlwm Kev Ua Haujlwm Piling
Hnyav-cov haujlwm piling tej yaam num ntsib ntau yam kev nyuaj uas hais txog kev xaiv cov khoom:
•Imense Vertical Loads: Cov pawg hauv paus yuav tsum txhawb nqa tag nrho qhov hnyav ntawm cov qauv loj, yuav tsum muaj kev thauj khoom axial siab - nqa lub peev xwm.
• Lub zog tom qab: Cua, seismic kev ua si, thiab cov dej ntws tawm ua haujlwm tseem ceeb rau sab nraud ntawm lub hauv paus, yuav tsum muaj kev khoov siab thiab lub zog.
• Cov Kev Nyuaj Siab Cov Av: Cov pawg feem ntau tau tsav los ntawm cov av mos lossis tsis ruaj khov kom ncav cuag cov kabmob ruaj khov, xav tau cov khoom siv uas tuaj yeem tiv taus kev tsav tsheb siab.
•Long-Lub Sij Hawm Durability: Cov pawg hauv paus yuav tsum nyob twj ywm zoo rau tag nrho lub neej ntawm cov qauv, feem ntau hauv cov av corrosive lossis marine ib puag ncig.
•Installation Efficiency: Lub peev xwm kom sai thiab ntseeg siab rau nruab ntau pawg yog qhov tseem ceeb rau lub sijhawm ua haujlwm thiab kev siv nyiaj txiag.
LSAW steel kav yog tsim tshwj xeeb tsim kom tau raws li qhov xav tau no.
Qhov Tseem Ceeb RauLSAW TubePreference nyob rau hauv Structure Piling
Kev ua tau zoo tshaj ntawm LSAW steel kav hauv hnyav - lub luag haujlwm piling yog tsav los ntawm ntau yam tseem ceeb:
1. Exceptional Strength thiab Load-Ncaj Muaj Peev Xwm
LSAW kav yog tsim los ntawm siab-zoo, siab- lub zog steel daim hlau (xws li, ASTM A252 Qib 3, API 5L X42 txog X70). Lawv cov txheej txheem tsim khoom tso cai rau:
• Loj Diameters thiab Hnyav Phab Ntsa Thicknesses: LSAW tshuab yog qhov tshwj xeeb tsim rau kev tsim cov kav dej nrog cov kab loj loj (txog 1422mm lossis ntau dua) thiab cov phab ntsa hnyav (txog 80mm lossis ntau dua). Qhov no ua rau pawg nrog loj heev axial thiab lateral load- nqa peev xwm.
•High Section Modulus: Qhov loj txoj kab uas hla thiab tuab phab ntsa muab ib tug siab seem modulus, uas txhais tau tias superior tsis kam rau dabtsi yog khoov thiab buckling nyob rau hauv lateral loads.
2. Superior Structureal Integrity thiab Weld Quality
Lub longitudinal weld seam ntawm LSAW kav yog tsim los ntawm Submerged Arc Welding (SAW) txheej txheem, uas xyuas kom meej:
•Full Penetration Weld: Sab hauv thiab sab nraud SAW tsim kom muaj zog, puv -kev nkag mus vuam uas muaj zog npaum li cov khoom siv niam txiv. Qhov no yog qhov tseem ceeb rau kev tswj cov pawg kev ncaj ncees thaum tsav tsheb thiab nyob rau hauv lub sijhawm ntev - loads.
•Kev Ua Zoo Zoo: Cov txheej txheem SAW automated, ua ke nrog 100% Tsis yog-Kev Ntsuam Xyuas Kev Puas Tsuaj (NDT) xws li ultrasonic thiab X-ray tshuaj xyuas, lav qhov siab - zoo, tsis xws luag- weld seam dawb.
•Resistance to Driving Stresses: Cov khoom siv vuam zoo thiab cov khoom zoo sib xws tso cai rau cov pawg LSAW tuaj yeem tiv taus qhov cuam tshuam hnyav thiab kev co ntawm pawg tsav tsheb yam tsis ua haujlwm.
3. Zoo heev Dimensional raug thiab ncaj
JCOE tsim cov txheej txheem thiab cov cuab yeej txuas ntxiv ua rau LSAW cov kav dej nrog qhov tseeb tshwj xeeb, suav nrog:
•Txoj kab uas hla sab nraud thiab phab ntsa Thickness: Ua kom muaj kev ua tau zoo ib yam thiab ua kom yooj yim txuas ntawm pawg pawg.
•Superior Straightness: Minimizes eccentric loading thiab xyuas kom meej tias pawg yog tsav kom raug rau nws qhov tob thiab kev sib tw.
•Zoo heev Roundness (Low Ovality): faib loads uniformly thiab txhim khu lub pawg tag nrho cov qauv stability.
4. Versatility thiab Customization
LSAW cov kav dej tuaj yeem hloov kho kom tau raws li cov kev xav tau tshwj xeeb ntawm txhua qhov project piling:
• Ntev Ntev: tuaj yeem tsim nyob rau hauv ib ntu ntev lossis yooj yim spliced hauv daim teb kom ncav cuag qhov tob uas xav tau.
• Ntau Qib Steel: tuaj yeem tsim los ntawm ntau qib steel los ua kom zoo zog thiab tus nqi- ua tau zoo.
•Adaptability rau Coatings: Lub du nto ntawm LSAW kav yog zoo tagnrho rau siv los tiv thaiv-corrosion coatings (xws li, epoxy, 3LPE) los yog siv rau cov pob zeb infill rau txhim khu kev qha load.
5. Kev txhim kho zoo thiab txhim khu kev qha
Qhov kev ua tau zoo thiab kev ua tau zoo ntawm LSAW steel kav ua rau kev txhim kho kom zoo:
•Drivability: Lawv lub zog siab thiab kev ua haujlwm ruaj khov ua rau lawv tsim nyog rau kev tsav tsheb nrog ntau txoj hauv kev, suav nrog kev cuam tshuam rau hammers thiab vibratory tsav tsheb.
• Yooj yim ntawm Splicing: Qhov tseeb qhov ntev thiab qhov kawg kev npaj ua kom yooj yim thiab siab - zoo welding ntawm pawg seem.
• Tam sim no Load Bearing: Cov yeeb nkab steel feem ntau tuaj yeem pib thauj khoom tam sim tom qab kev teeb tsa, muaj peev xwm ua kom lub sijhawm ua haujlwm nrawm.
