Cov Mechanics ntawm Choj Piling
- Features ib qho ncaj weld nrog txoj kev luv luv weld, muab kev ua haujlwm qaug zog zoo dua piv rau SSAW (kauv-welded) kav- ua rau nws zoo tagnrho rau kev ua haujlwm ntev - lub sij hawm dynamic loads ntsib los ntawm txuas hniav.
- Qhov siab qhov tseeb thiab qhov tsawg kawg nkaus tawm - ntawm - roundness kom zoo dua pawg tsav tsheb thiab kev ua haujlwm borehole casing.
- Muaj peev xwm ua tau tuab -walled, loj- txoj kab uas hla specifications kom tau raws li cov load- bearing yuav tsum tau ntawm cov sib sib zog nqus pawg foundations ntev -span txuas hniav.
- Weld seams tso cai rau 100% ultrasonic (UT) lossis radiographic (RT)tsis yog-kev sim ua kom puas tsuaj, ua rau cov khoom tsim nyog rau cov chaw tseem ceeb hauv nroog thiab hla-sea choj tej yaam num.

FAQ
Q: Vim li cas LSAW steel kav thiaj li nyiam tshaj SSAW (Spiral-Welded) kav rau cov choj tseem ceeb?
A: Thaum muab kauv-welded (SSAW) cov kav dej yog tus nqi siab heev-zoo rau cov ntawv thov qis-,LSAWcov kav dej yog universally teev rau hnyav structural choj foundations. 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 puas tuaj yeem muab cov khoom siv sib xyaw ua ke xws li cov khau tsav tsheb lossis cov hlua khi?
A: Yog, kiag li. Txhawm rau txuag koj qhov tseem ceeb sub- lub sijhawm cog lus ntawm -site, peb muab tag nrho lub Hoobkas- kev sib xyaw ua ke. Peb tuaj yeem ua ntej-weld hnyav-lub luag haujlwmconical tsav khaulos yog cov txheej txheem txiav cov hniav mus rau hauv qab cov lus qhia ntawm cov kav dej kom pab nkag mus rau cov pob zeb tuab. Tsis tas li ntawd, peb tuaj yeem nruab sab hauvshear ringslos yog mechanical lock-joints raws nraim ntawm koj engineering drawings ua ntej xa nkoj.
Q: Yuav ua li cas koj txheeb xyuas cov qauv kev sib xws ntawm thaj chaw weld rau pawg uas raug hnyav lateral dabtsi yog khoov?
A: Cov pawg choj tau raug rau lub zog loj heev los ntawm cov cua thiab dej tam sim no, uas ua rau muaj kev ntxhov siab hnyav rau ntawm lub vuam seam. Txhawm rau lav 100% qhov tsis xws luag-dawb cov qauv profiles, peb lub Hoobkas siv ntau-theem tsis-kev ntsuas kev puas tsuaj (NDT) matrix. Tam sim ntawd tom qab welding, tag nrho ntev ntawm lub longitudinal seam undergoes automatedKev kuaj ultrasonic (UT). Tsis tas li ntawd, cov yeeb nkab kawg tau txheeb xyuas los ntawmSiab -Kev Ntsuas Radiographic (RT/X-ray)thiab Magnetic Particle Inspection (MPI) raws lub ntsej muag bevel.
Q: Cov ntaub ntawv twg yog muab los ua kom tau raws li kev soj ntsuam thoob ntiaj teb nruj?
A: Txhua qhov kev xa khoom ntawm peb cov txheej txheem piling yeeb nkab yog xa nrog ib tus neeg ua haujlwm, tag nrho traceableMill Test Certificate (MTC) ua raws EN 10204 3.1. Cov ntaub ntawv no sau cov naj npawb ntawm cov cua sov, cov tshuaj lom neeg muaj pes tsawg leeg (xws li Carbon Equivalent xam), thiab cov ntaub ntawv ntsuas kev ua haujlwm ntawm lub cev (Tensile Strength, Yield Strength, thiab Elongation feem pua), muab cov ntaub ntawv ua tiav rau koj qhov project inspectors thiab structural auditors.
