Cov Mechanics ntawm Piling Hauv ASTM A252 Qib 2
Sourcing foundation steel yuav tsum muaj kev nkag siab meej ntawm cov khoom siv hlau thiab cov ntsuas ntsuas tau teev tseg los ntawm American Society for Testing and Materials (ASTM):
- Symmetrical Stresses ntawm Piling:Cov pawg hauv paus tau txais kev ntxhov siab heev, axial, thiab khoov kev ntxhov siab thaum lub sij hawm ob qho kev teeb tsa (kev cuam tshuam rauj) thiab lawv lub neej ua haujlwm. Circular hollow seem muab tib yamkhoov tsis kam thiab lub vojvoog ntawm gyrationthoob plaws tag nrho 360 degrees, ua tau zoo tshaj cov tsoos H- pawg hauv kev hloov cov av hauv hiav txwv.
- ASTM A252 Qib 2 Mechanical Benchmarks:Qhov no specification yog optimized meej meej rau structural steel piling. Qib 2 lav qhov tsawg kawg nkaus yield zog ntawm35,000 psi (240 MPa)thiab qhov tsawg kawg nkaus tensile lub zog ntawm60,000 psi (415 MPa). Qhov kev sib npaug meej no ua kom cov yeeb nkab nruj txaus los daws qhov hnyav ntawm kev tsav tsheb yam tsis muaj kab buckling, tsis tau ductile txaus los nqus lateral load hloov.
- LSAW Manufacturing Integrity:Peb cov kav dej piling siv txoj hlua ncaj nraim. Vim hais tias cov kab vuam yog kiag li ncaj thiab zoo ib yam, nws undergoes tsawg residual manufacturing kev nyuaj siab thiab muaj peev xwm txheeb xyuas nyob rau hauv 100% ntawm nws ntev siv automated non-kev ntsuam xyuas kev puas tsuaj (NDT), lav qhov kev ua tau zoo nyob rau hauv nruj nruj structural strain.

Key Performance Advantages & Product Benefits
Exceptional Resistance rau siab -Ib feem tsav tsheb Stresses
Thaum lub sij hawm installation, diesel los yog hydraulic piling hammers xa ntau lab tus taw -pounds ntawm lub zog ncaj qha mus rau sab saum toj ntawm cov yeeb nkab. Peb cov kav dej ASTM A252 Gr.2 LSAW muaj qhov tshwj xeeb ntawm phab ntsa thickness uniformity thiab ncaj, ua kom lub zog rauj txhais ncaj qha rau hauv kem mus rau hauv txaj tsis muaj cov phab ntsa crimping.
Tag Nrho -Length Cold Expansion for Extreme Precision
Ua raws li cov txheej txheem vuam tsis siv neeg, 100% ntawm peb cov LSAW piling pipes undergo automated mechanical cold expansion. Cov txheej txheem tseem ceeb no tshem tawm cov kev tsim khoom sab hauv los ntawm cov phaj dov thiab ua kom nruj txheej kab (OD) thiab geometric roundness kam rau ua, ua kom yooj yim rau ntawm - qhov chaw splicing thiab teb welding.
Kho Corrosion Defense rau Aggressive Marine Zones
Txau dej hiav txwv thiab dej hiav txwv sai sai degrade hlau tsis muaj kev tiv thaiv. Peb muab ntau yam ntawm siab - lub Hoobkas ua kom tiav, suav nrog hnyav - lub luag haujlwmFusion Bonded Epoxy (FBE), Coal Tar Epoxy, thiab kev cai marine-qib polyurethane txheej txheej tsim los cais cov hlau thiab lav ntau xyoo ntawm kev saib xyuas- kev pabcuam dawb subsea.

FAQ
Q: Dab tsi yog qhov tseem ceeb ntawm cov kav dej LSAW tshaj SSAW (Spiral-Welded) kav rau choj piling?
A: Thaum muab kauv-welded (SSAW) cov kav dej yog tus nqi siab heev- siv tau rau cov ntawv thov dej,LSAWcov kav dej yog qhov zoo dua rau qhov hnyav ntawm cov qauv choj hauv paus. LSAW siv ib txoj hlua ncaj nraim es tsis yog ib qho spiraling seam. Thaum muaj kev cuam tshuam loj hauv pawg tsav tsheb, lub zog tsav tsheb mus rau hauv txoj kab ncaj nraim hauv cov yeeb nkab. LSAW txoj kab ncaj nraim sib phim txoj hauv kev lub zog no zoo kawg nkaus thiab dhau los ua qhov txias txias- txheej txheem nthuav dav uas ua kom muaj kev sib tw ntau dua thiab cov qauv kev kwv yees nyob rau hauv crushing loads.
Q: Koj lub zeb ua li cas rau qhov huab "Length Customization" xav tau rau cov sib sib zog nqus marine sib sib zog nqus pawg?
A: Sib sib zog nqus- dej hiav txwv hauv paus feem ntau xav tau cov kab txuas txuas ntxiv ntev tshaj 30 meters, uas tsis tuaj yeem haum rau cov qauv thauj khoom. Peb muab ob txoj kev daws teeb meem: peb tuaj yeem muab cov qauv 12m lossis 15m ntu nrog lub Hoobkas -machined precision bevels rau ceev ceev ntawm -site teb splicing, lossis peb tuaj yeem ua tiavFactory Splicing thiab Testing. Peb cov welders tau ntawv pov thawj koom ua ke luv luv ua ke nyob rau hauv cov txheej txheem rhiav automated, ua raws li 100% Ultrasonic weld soj ntsuam, xa ultra-ntev ib zaug- tej pawg ncaj qha rau koj lub nkoj.
Q: Vim li cas "Weld Reinforcement (Bead Height) Control" tseem ceeb rau cov kav dej uas tau tsav nrog cov khau sab hauv los yog mandrel?
A: Thaum tsav cov kav dej mus rau hauv cov av nplaum los yog cov av pob zeb, cov neeg cog lus feem ntau siv cov tsav tsheb sab hauv lossis cov khau hnyav hnyav rau hauv qab. Yog hais tias lub sab hauv los yog sab nraud weld hlaws qhov siab (reinforcement) siab dhau lawm, nws tuaj yeem cuam tshuam nrog kev ua siab ntev ntawm kev tsav tsheb. Peb cov kab LSAW automated siv cov cuab yeej tshwj xeeb milling los txiav cov weld reinforcement mus rau qhov siab yam tsawg kawg nkaus (feem ntau hauv qab 1.5mm), kom ntseeg tau tias cov khoom siv tau zoo.
Q: Puas yog ASTM A252 Qib 2 puas yuav tsum tau kuaj hydrostatic zoo li cov kav dej txheem?
A: Tsis yog. Vim tias ASTM A252 yog kev mob siab raustructural piling txheemthiab tsis yog cov dej sib kis tshwj xeeb, kev sim hydrostatic tsis raug cai los ntawm cov cai tseem ceeb. Hloov chaw, kev nyab xeeb ntawm cov qauv raug txheeb xyuas los ntawm kev ntsuas kev puas tsuaj rau cov tshuab, suav nrogTensile TeststhiabWeld Khoov Tests, nrog rau cov khoom tsis zoo -kev kuaj kev puas tsuaj (Ultrasonic thiab X-ray) raws cov kab txuas txuas ntev kom ntseeg tau tias cov yeeb nkab yuav tsis tawg thaum muaj kev cuam tshuam loj heev.
