Nkag siab txog ASTM A252 Yeeb Nkab: Ib qho tseem ceeb hauv kev siv Piling
Nyob rau hauv lub ntiaj teb no ntawm kev tsim kho thiab civil engineering, qhov tseem ceeb ntawm cov ntaub ntawv txhim khu kev qha tsis tuaj yeem overstated. Nyob rau hauv xyoo tas los no,ASTM A252 Tubetau txais kev mloog ntau. Qhov kev qhia tshwj xeeb no yog qhov tseem ceeb tshwj xeeb rau cov haujlwm uas cuam tshuam nrog kev ua haujlwm piling, vim tias kev ncaj ncees thiab ua haujlwm ntev ntawm cov ntaub ntawv siv ncaj qha cuam tshuam rau kev ua tiav lossis tsis ua haujlwm ntawm lub tsev.
Cangzhou Spiral Steel Pipe Group Co., Ltd. yog nyob rau hauv plawv nroog Cangzhou, Hebei xeev. Nws tau ua tus thawj coj welded yeeb nkab chaw tsim tshuaj paus txij li thaum nws tsim nyob rau hauv 1993. Lub tuam txhab npog thaj tsam ntawm 350,000 square metres, muaj tag nrho cov cuab tam ntawm RMB 680 lab, thiab muaj kwv yees li 680 tus neeg txawj thiab cov neeg ua haujlwm. Kev nplua nuj thiab kev tsim vaj tsev muaj zog ua rau lub tuam txhab tsim cov kav dej zoo ASTM A252 uas ua tau raws li cov kev cai nruj ntawm kev tsim kho kev lag luam.
ASTM A252 specification npog nominal phab ntsa steel tubular pawg uas yog cylindrical nyob rau hauv cov duab. Cov pawg no yog tsim los siv los ua cov tswvcuab cov kabmob ruaj khov lossis ua vaj tse rau cov pob zeb cast-in-place. Qhov kev ua haujlwm dual no yog qhov tseem ceeb los xyuas kom meej tias cov qauv kev ncaj ncees ntawm lub hauv paus yog khaws cia rau lub sijhawm ntev. Hauv cov ntawv thov uas cov av tej zaum yuav xav tau, kev siv ASTM A252 tubular piles yog qhov zoo tshwj xeeb vim tias lawv muab lub zog thiab ruaj khov uas yuav tsum tau los txhawb nqa hnyav.
Kev ua tau zoo thiab kev ua haujlwm ntev ntev
Astm A252 Pipe Dimensionspiles muaj cov txiaj ntsig tseem ceeb hauv qab no:
Ua los ntawm high-strength steel, nws muaj zoo heev load-bearing kev ua tau zoo
Kev kho kev tiv thaiv corrosion, haum rau qhov hnyav ib puag ncig xws li dampness thiab saline-alkali tej yam kev mob
Nws tuaj yeem siv los ua cov khoom siv thauj khoom mus tas li lossis lub plhaub ntawm cov pob zeb pob zeb
Txo tus naj npawb ntawm cov pob qij txha ntawm qhov chaw thiab txhim kho tag nrho cov txheej txheem lub zog
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv ASTM A252 cov kav dej hauv kev siv piling yog lawv lub peev xwm los tiv thaiv ib puag ncig hnyav. Cov hlau siv hauv cov kav dej no tau kho kom tiv thaiv corrosion, ua kom lawv lub neej ntev thiab txo cov nqi tu mus sij hawm ntev. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas cov kav dej yuav raug rau cov av ntub lossis hnyav av ib puag ncig.
Tsis tas li ntawd, Cangzhou Spiral Steel Pipe Group Co., Ltd. cov txheej txheem tsim ua raws li kev tswj xyuas nruj kom ntseeg tau tias txhua cov yeeb nkab uas tsim tau raws li cov qauv kev lag luam siab tshaj plaws. Qhov kev cog lus rau kev ua tau zoo tsis yog tsuas yog txhim kho kev ua tau zoo ntawm cov yeeb nkab, tab sis kuj txhim kho kev ntseeg siab ntawm cov neeg cog lus thiab cov kws tsim khoom uas vam khom cov ntaub ntawv no rau lawv cov haujlwm.
Txhua yam, ASTM A252 yeeb nkab yog ib qho tseem ceeb ntawm kev tsim kho kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev siv piling. Nrog kev txawj ntse thiab cov peev txheej ntawm Cangzhou Spiral Steel Pipe Group Co., Ltd., cov neeg siv khoom tuaj yeem paub tseeb tias tau txais cov kav dej zoo zoo uas ua tau raws li lawv cov kev xav tau tshwj xeeb. Raws li qhov kev thov rau cov khoom siv ruaj khov thiab txhim khu kev qha txuas ntxiv zuj zus, ASTM A252 yeeb nkab yuav tsis muaj qhov xav tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev txhim kho yav tom ntej. Txawm hais tias koj koom nrog kev tsim kho loj lossis ib qho me me, xav txog qhov zoo ntawm kev sib koom ua ke ASTM A252 yeeb nkab rau hauv koj lub hauv paus kev daws teeb meem.
