Thaum nws los txog rau kev tsim kho thiab kev xaiv pej xeem, cov khoom xaiv yog qhov tseem ceeb los ua kom muaj kev ncaj ncees thiab kev ua haujlwm ntev. Ib cov ntaub ntawv uas tau txais lub koob npe nrov hauv kev lag luam yogASTM A252 Qib 2Yeeb nkab pawg. Cov blog no yuav hais rau hauv cov kev qhia tshwj xeeb, cov khoom, thiab khij cov kev xav tau ntawm Astm A252 qib 2 kom tau kev nkag siab zoo ntawm nws qhov tseem ceeb hauv kev tsim kho cov dej num.
Dab tsi yog ASTM A252 qib 2?
ASTM A252 yog tus qauv kev qhia tshwj xeeb rau Welded thiab seamless steel tubular piles rau lub hauv paus thov. Qeb 2 yog ib ntawm peb qib teev nyob rau hauv tus qauv no, nrog qib 1 ua qhov qis tshaj plaws thiab qib 3 yog qhov siab tshaj plaws ntawm kev cog lus lub zog. ASTM A252 Qib 2 Tubular pawg yog tsim los muab kev sib npaug ntawm lub zog thiab ductility, suav nrog ntau lub hauv paus, thiab lwm yam xwm txheej-cov kev sib tw.
Cov yam ntxwv tseem ceeb ntawm Astm A252 Qib 2 suav nrog cov txiaj ntsig tsawg kawg lub zog ntawm 35,000 psi thiab tsawg kawg tensile lub zog ntawm 60,000 psi. Cov khoom siv no ua kom cov pawg tuaj yeem tiv tau cov khoom tseem ceeb thiab kev ntxhov siab, ua rau lawv zoo tshaj rau kev siv hauv cov chaw sib tw.
ASTM A252 Qib 2 Yeeb Nkab Piles Yuav Tsum Muaj
Ib qho tseem ceeb ntawm ASTM A252 Qib 2 piles yog qhov xav tau ntawm kev khij tsim nyog. Txhua pawg yuav tsum yog cim kom pom tseeb los muab cov ntaub ntawv tseem ceeb ntawm cov khoom. Qhov kev cim no yog qhov tseem ceeb rau traceability, muaj kev paub zoo, thiab ua raws li cov qauv kev lag luam. Cov ntsiab lus hauv qab no yuav tsum muaj nyob hauv cov cim:
1.Manufacturer lub npe lossis hom: Qhov no qhia txog cov chaw tsim tshuaj paus ntawm pawg, kom ntseeg tau tias tus neeg siv tuaj yeem ua cov khoom rov qab rau nws qhov chaw.
2. Cov naj npawb kub: Tus lej kub yog tus cim tshwj xeeb uas tau muab rau ib qho kev sib txuas ntawm cov hlau. Nws tso cai rau lub hauv paus chiv keeb thiab cov yam ntxwv ntawm cov khoom yuav tsum tau traced, uas yog qhov tseem ceeb rau kev tswj kom zoo.
3.Manupacturer Txheej Txheem: Qhov no qhia tias tus qauv siv los ua cov pawg, seb welded lossis seamless. Nkag siab txog cov txheej txheem tsim khoom pab rau kev ntsuas cov yam ntxwv ntawm cov pawg.
4.Qhov kev sib koom tes sib koom ua ke: hom ntawm cov kauv sib koom ua ke siv hauvYeeb pawgyuav tsum tau cim, yog tias muaj. Cov ntaub ntawv no tseem ceeb rau kev nkag siab cov qauv kev ncaj ncees ntawm pawg.
5.outer inch: sab nraud ntawm lub cheeb yuav tsum tau cim kom meej raws li nws yog qhov tseem ceeb rau kev teeb tsa thiab kev thauj khoom.
6.Tnominal phab ntaub tuab: lub phab ntsa tuab ntawm pawg yog lwm qhov ntsuas tseem ceeb uas cuam tshuam nws lub zog thiab kev coj tau muaj peev xwm.
7.Kh thiab qhov nyhav ib qho ntev: tag nrho ntev thiab qhov hnyav ib qhov ntev ntawm pawg yuav tsum tau hais. Cov ntaub ntawv no yog qhov tseem ceeb rau kev thauj thiab npaj kev teeb tsa.
8.Sepecification lub npe thiab qib kawm: Thaum lub cim yuav tsum muaj lub npe tshwj xeeb (ASTM A252) thiab qib 2) kom paub meej raws li cov qauv kev lag luam.
Hauv kev xaus
ASTM A252 Qib 2 Yeeb Nkab Piles yog qhov tseem ceeb ntawm kev tsim kho tshiab, muab cov khoom tsim nyog thiab lub zog rau ntau yam kev siv. To taub txog cov kev qhia tshwj xeeb thiab kev kos cim yog qhov tseem ceeb rau cov engeters, cov thawj coj, thiab cov thawj tswj haujlwm kom paub meej tias lawv siv cov ntaub ntawv raug rau lawv cov haujlwm. Los ntawm adhering rau cov qauv no, kev tsim kho kev tsim kho tuaj yeem ua kom muaj kev ua haujlwm zoo thiab ua kom muaj kev nyab xeeb thiab kev ua haujlwm tau ua rau cov tswv yim.
