Q1: Cov qauv hauv ntiaj teb no siv rau Q235B Welded yeeb nkab?
A1: Q235B Welded Yeeb Nkab xws li GB / T 3091 (rau kev siv dav dav) thiab GB / T 13793 (rau cov hom phiaj txheej txheem). Thoob ntiaj teb, cov qhab nia zoo sib xws muaj xws li ASTM A53 (US) thiab EN En 10219 (Tebchaws Europe). Cov qauv no txhais tau qhov ntev, kev ua kom tau zoo, thiab cov yam ntxwv. Thaum Q235b yog kev tsim qauv Suav, cov ntaub ntawv sib npaug tuaj yeem nrhiav tau hauv lwm cov qauv nrog kev sib txawv me ntsis hauv kev sib xyaw. Cov tuam txhab tsim nyog yuav tsum ua kom muaj kev ua raws cov kev qhia tshwj xeeb rau cov lag luam xa tawm.
Q2: Dab tsi yog qhov seem tsis muaj kev pab rau Q235B Welded yeeb nkab?
A2: Cov txheej txheem hla kev thev naus laus zis feem ntau yog li ntau los ntawm ± 0.5% mus rau ± 0.5% rau ± 1.0%, nyob ntawm tus qauv. Phab ntsa Thuab trealness tas yog feem ntau nyob rau hauv ± 10% ntawm nominal tuab. Ntev ua siab ntev sib txawv tab sis feem ntau ± 10 hli rau cov kav dej tsau. Kev ncaj yuav tsum tsis pub tshaj 1.5 hli ib meter. Cov thev taus muaj tseeb kom haum rau kev tsim kho thiab tshuab ua ke.
Q3: Yuav sib piv pes235b piv rau Q195 thiab Q345 Welded Pipes li cas?
A3: Q235B tau muaj ntau dua lub zog (235 mpa) tshaj li Q195 (195 MPa) tab sis qis dua Q345 (345 MPa). Q195 yog ntau dua cookile thiab siv rau cov ntawv thov teeb lub sij hawm, thaum Q345 muaj lub zog zoo dua rau cov qauv hnyav. Q235b tiv thaiv kev sib npaug ntawm tus nqi thiab kev ua tau zoo, ua nws ntau yam kev xaiv. Tshuaj lom neeg cov khoom siv tshuaj kuj txawv, nrog Q345 uas muaj ntau cov ntsiab lus xws li Vanadium thiab Niobium rau kev txhim kho lub zog.
Q4: Yuav ua li cas cov kev kho hauv cov tshuaj q235b welded yeeb nkab?
A4: Cov kev kho cov npoo sib xws xws li kub-dip galvanizing, electro-galvanizing, thiab pleev xim. Kub-DIP Galvanizing muab cov yeeb nkab zoo heev los ntawm txheej yeeb nkab nrog zinc. Electro-galvanizing muaj ib tug thinner, smoother zinc txheej rau lub hom phiaj ua kom zoo nkauj. Painting los yog hmoov txheej ua kom zoo nkauj thiab muab kev tiv thaiv ntxiv. Dub (tsis kho) kav dej tseem muaj rau cov ntawv thov sab hauv tsev lossis cov ntawv thov ib ntus.
Q5: Cov yeeb yaj kiab yuav tsum muaj rau Q235B Welded yeeb nkab?
A5: Q235B Welded Pipes yauv kuaj Tensile, khoov kuaj, thiab kev cuam tshuam kev ntsuas kom txheeb xyuas cov khoom siv neeg kho tshuab. Tsis yog-kev sim ua phem (NDT) zoo li ultrasonic lossis xov tooj cua soj ntsuam Weld Weld Kev Ncaj Ncees. Hydrostatic lossis pneumatic cov kev sim ua kom pom tau tias muaj kev ua haujlwm hauv siab. Tshuaj lom neeg tshuaj lom neeg txheeb xyuas kom paub meej tias ua raws li cov qauv. Cov ntawv pov thawj zoo li ISO 9001 tej zaum yuav xav tau kev ntsuas zoo.
