Cov Lus Qhia Txog Qib Hlau H Beam: ASTM, EN, thiab GB Cov Qauv Piav Qhia

Hauv kev lag luam thoob ntiaj teb ntawm kev tsim kho vaj tse thiab kev tsim kho vaj tse, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov ntaub ntawv tsim kho kom zoo rau kev nyab xeeb, lub neej ntev thiab kev siv nyiaj tsim nyog. Ua lub koob npe nrovTus Muag Khoom H Beam,Paub cov qauv hlau los ntawm thoob plaws ntiaj teb - Cov Qauv Thoob Ntiaj Teb rau Hlau - ASTM (Asmeskas), EN (European), GB (Suav) - Cov kws ua vaj tse thiab cov neeg yuav khoom yuav tsum muaj kev nkag siab meej.

Phau ntawv qhia no muab kev piav qhia txog cov qib hlau feem ntau siv los ntawmCov Hlau Carbon H BeamCov chaw tsim khoom thoob ntiaj teb.

ASTM Cov Qauv (North America)

Lub Koom Haum Asmeskas rau Kev Ntsuas thiab Cov Khoom Siv (ASTM) teeb tsa tus qauv rau feem ntau ntawm cov haujlwm hauv Western Hemisphere.

ASTM A36 H BeamQib "steel mos" uas siv ntau tshaj plaws. Yam tsawg kawg nkaus ntawm 36 ksi (250 MPa), lub zog tso zis yog qhov siab thiab nws muaj kev sib txuas zoo thiab ductility uas ua rau nws yog ib qho ntawm cov hlau zoo tshaj plaws rau kev tsim kho dav dav thiab kev sib dhos bolted.

A572 H Beam (Qib 50)Cov hlau uas muaj zog siab (HSLA). Lub zog siab dua (50 ksi / 345 MPa) ntawm A572 H beam piv rau A36 ua rau siv tau cov seem sib dua rau tib lub nra, yog li txuag qhov hnyav ntawm tag nrho cov haujlwm.

A992 H Beam: Qhov kev xaiv siv ntau tshaj plaws rau cov kab hluav taws xob dav dav hauv Tebchaws Meskas uas koj yuav pom niaj hnub no. Nws yog ib qho tshuaj lom neeg tshwj xeeb, tsim los rau kev txhim kho weldability thiab qhov sib piv yield-to-tensile nqaim dua rau cov ntawv thov av qeeg.

Cov Qauv EN (Tebchaws Europe)

Tus Txheej Txheem European (EN 10025 H Beam) siv cov kev cai npe raws li lub zog tsawg kawg nkaus hauv Megapascals (MPa).

S235JR H BeamQib European ntawm A36. Nws muaj lub zog tso zis ntawm 235 MPa. Lub npe "JR" yog qhov tshwm sim ntawm qhov tseeb tias cov hlau tau raug kuaj xyuas qhov cuam tshuam ntawm chav tsev kub (20 ° C).

S275JR H BeamCov hlau ua vaj tse nruab nrab (lub zog tawm los = 275 MPa). Nws feem ntau siv rau hauv kev tsim choj thiab cov thav duab khoom siv hnyav.

S355JR H BeamCov Hlau Muaj Zog S355JR yog qib siv dav tshaj plaws ntawm cov hlau muaj zog siab hauv phau ntawv teev npe EN. Nrog lub zog tso zis ntawm 355 MPa nws kuj yog cov khoom siv xaiv rau cov tsev siab thiab cov qauv hauv hiav txwv qhov twg qhov hnyav rau lub zog sib piv yog qhov tseem ceeb.

GB Cov Qauv (Tuam Tshoj)

Raws li Tuam Tshoj tseem yog lub ntiaj teb cov neeg tsim khoom loj tshaj plaws, ntauCov Hlau CarbonCov Neeg Muag Khoom H Beamua raws li GB/T 11263 tus qauv.

Q235 H BeamZoo ib yam li S235JR thiab A36. Lub cim "Q" hauv Q235 sawv cev rau qhov taw tes thaum 235 qhia txog lub zog hauv MPa. Nws kuj tseem siv rau hauv cov tsev theem ob thiab cov pej thuam sib txuas lus.

Q355 H BeamCov hlau no yog cov khoom siv tseem ceeb hauv Suav teb uas muaj zog heev. Nws yog ib yam khoom siv uas hu ua S355JR sib npaug, uas siv dav hauv cov tsev ua ntej tsim ua hlau (PEB) thiab cov chaw tsim khoom loj.

Vim Li Cas Xaiv Tus Neeg Muab Khoom H Beam Zoo Thiaj Tseem Ceeb

Yuav kom ua tau raws li cov qauv no, koj xav tau tus khub uas muaj kev paub txog daim ntawv pov thawj hla ciam teb. Cov Hlau Carbon Zoo Tshaj PlawsCov Chaw Tsim Khoom H Beamtam sim no muab Daim Ntawv Pov Thawj Xeem Zeb (MTC) qhia txog "Dual Certification;" ib lub nqaj tuaj yeem tau ntawv pov thawj rau ob qho tib si S355JR thiab Q355 tib lub sijhawm.

Txawm koj lub tsev rau khoom nyob hauv Mexico, koj tus choj nyob hauv Philippines, Kev xaiv qib zoo rau txoj haujlwm muab kev thaj yeeb nyab xeeb hauv kev paub tias txoj haujlwm yuav tsis tsuas yog muaj kev ruaj ntseg zoo xwb tab sis kuj yog tias koj tau siv koj cov peev nyiaj khoom siv ntau tshaj plaws.
