Txhua kab kis tau tus mob pib nrog ib phau ntawv code. IEC 60826 npog cov txheej txheem thauj khoom rau cov kab saum toj 45 kV. Teb chaws Europe ntxiv EN 50341 nrog nws daim ntawv qhia cua thiab dej khov. Cov engineers hauv North America ncav cuag ASCE / SEI 10-15, thiab cov khoom siv hauv Suav teb ua haujlwm los ntawm GB 50017 thiab DL / T 5092. Cov qauv no qhia koj tias lub zog steel xav tau dab tsi. Tsis muaj leej twg qhia koj tias yuav ua li cas thaum cov hlau ntawd tsoo lub galvanizing da dej ntawm 450 degrees Celsius.
Peb tau muab kub- dov coil rau ntauwd fabrication ntev txaus kom paub tias daim ntawv pov thawj yog qhov yooj yim. Q235B, kwv yees sib npaug rau ASTM A36, nkag mus rau hauv ob sab bracing thiab hla - caj npab. Cov ceg tseem ceeb feem ntau khiav Q345B, uas kab nrog ASTM A572 Qib 50. Cov haujlwm European qhia S355J2. Yog tias txoj kab hla roob hla los yog thaj chaw sab qaum teb uas lub caij ntuj no kub poob qis dua 20, peb thawb cov neeg siv mus rau Q345D lossis S355J2 vim tias cov qib no muaj Charpy pov thawj ntawm rho tawm 20 degrees. Q345B tsis yog, thiab qhia meej rau qhov chaw txias yog qhov yuam kev uas peb pom ntau dua li qhov koj xav tau.
Qhov kev sim tiag tiag ntawm ntauwd steel yoggalvanizing teb.
Silicon yog lub hauv paus uas ua rau muaj kev sib cav
Kub-dip galvanizing rau ISO 1461 lossis ASTM A123 yog tus qauv thoob plaws hauv kev lag luam. Ntawm cov seem tshaj 6 millimeters, qhov tsawg kawg nkaus txheej yog 85 micrometers. Hauv cov cheeb tsam nyob deb nroog lossis lub teeb pom kev hauv nroog tau faib ua C2 lossis C3 raws li ISO 12944, qhov tuab feem ntau tuav txog 40 txog 50 xyoo. Ntawm qhov chaw ntug dej hiav txwv hauv C5 qeb, koj tuaj yeem tau txais ib nrab ntawm qhov ntawd, uas yog vim li cas cov kws ua haujlwm hauv cov cheeb tsam no feem ntau qhia cov txheej txheem duplex nrog cov xim pleev xim rau zinc.
Ib feem uas tau saib tsis taus yog chemistry. Muaj ntau yam silicon, kwv yees li 0.04 txog 0.14 feem pua, qhov twg hlau ua li cas galvanizers hu ua reactive. Cov hlau-zinc alloy txheej loj hlob sai heev. Cov txheej txheem los ntawm tuab, dull grey, thiab nkig. Punch ib lub qhov los yog khoov lub kaum sab xis thiab nws flakes. Peb tau pom tag nrho cov khoom tsis lees paub vim tias lub zeb tsis tuav silicon hauv qab lub qhov rais. Peb tswj nws ntawm theem melting, nrog rau phosphorus, yog li cov zinc mus sib npaug thiab nyob twj ywm matte grey hla txhua tus tswv cuab hauv cov lattice.
Fabricators mob siab rau flatness ntau dua qib
Cov duab kos qhia qib thiab tuab. Cov neeg khiav lub punch kab mob siab txog qhov dav variation, ntug nthwv dej, thiab crown. Peb tuav thickness rau ntxiv lossis rho tawm 2 feem pua ntawm tag nrho cov kauj dav thiab xyuas txhua qhov kev khiav nrog laser ntsuas. Cov ntaub ntawv khaws cia rau ib lub kauj, tsis yog ib qho khoom xa tuaj.
Nws suab zoo li me me kom txog thaum koj tau khiav ib puas tons ntawm kaum. Qhov uas tsis sib haum yuav tsum tau reaming. Cov khoom uas yuav tsis zes huv si txhais tau tias cov khoom seem ntxiv, thiab ntawm qhov project ntauwd uas seem tuaj yeem khiav mus rau hauv cov nyiaj tiag. Peb cov khoom pov tseg feem ntau nyob qis dua 0.5 feem pua. Peb kuj khaws cov pa roj carbon sib npaug ntawm 0.40 feem pua lossis qis dua, uas txhais tau hais tias cov welders ntawm qhov chaw tsis xav tau hnyav preheat txawm nyob rau ntawm cov ceg tuab. Nyob rau lub roob saum toj kawg nkaus lub Ib Hlis, qhov ntawd tsis yog qhov nthuav dav. Nws yog seb cov neeg coob tau txais qhov sib txuas kaw ua ntej lub teeb mus.
Bolts yog qhov chaw zoo coatings mus phem
Peb tsis ua fasteners. ASTM A394 npog galvanized bolts thiab txiv ntseej rau kev sib kis ua haujlwm, thiab qhov ntawd yog cov saw hlau sib cais. Tab sis peb ib txwm hais rau cov neeg siv khoom kom kuaj xyuas lub bolt txheej thickness tiv thaiv cov tapping qhov hauv peb cov hlau. Yog tias zinc ntawm lub ntsia liaj qhov rooj hnyav dua li qhov kev tso cai, cov xov strips thaum koj torque lawv. Cua vibration ua tus so. Nws yog hom teeb meem uas tshwm sim rau lub hlis tom qab erection, thiab los ntawm ces tsis muaj leej twg xav lees tias nws yog kev txiav txim siab yuav khoom.
Ib daim ntawv ntawm dawb xeb
Kev ntub dej stain, los yog xeb dawb, tshwm sim thaum cov hlau tshiab galvanized yog ntim nruj thiab condensation tau daig ntawm qhov chaw. Nws yog chalky, dawb, thiab feem ntau tsis yog cov qauv, tab sis nws yuav tuav ib qho kev kuaj xyuas txhua lub sijhawm. Peb siv cov cua tshuab pa hauv peb cov ntim thiab qhia cov neeg tsim khoom kom khaws cov tswv cuab hauv qab npog nrog huab cua txav ntawm lawv. Nws tsis raug nqi dab tsi thiab tiv thaiv kev sib cav uas tuaj yeem kav ntev dua li theem erection.
Yuav nug koj tus neeg muag khoom dab tsi
Daim ntawv ntsuam xyuas zeb yog lub hauv paus. Txhua tus neeg muag khoom muaj npe nrov tuaj yeem tsim ib qho. Cov lus nug uas cais cov neeg muag khoom yog hais txog cov txheej txheem. Koj tswj silicon li cas? Koj puas muaj cov ntaub ntawv thickness variation hla lub kauj dav? Koj puas tuaj yeem qhia Charpy cov ntaub ntawv rau qib qis - kub? Koj puas yuav muab EN 10204 3.1 daim ntawv pov thawj batch los ntawm batch?
Peb ua haujlwm rauISO 9001 thiab ISO 14001, thiab peb cov coil tau mus rau hauv kev sib kis hauv ntau tshaj 50 lub teb chaws. Q235B, Q345B, Q345D, thiab S355J2 yog tag nrho nyob rau hauv kev tsim khoom, yog li lub sij hawm txhuas tsis txhob dhia ncig thaum qhov kev txiav txim loj.,
Yog tias koj tab tom ua tus nqi ib kab thiab xav pom cov ntawv ceeb toom tiag tiag los yog cov ntaub ntawv sib tw galvanizing, koj tuaj yeem nrhiav tau peb cov coil specifications ntawm [nplooj ntawv khoom] lossis hu rau peb ncaj qha los ntawm [daim ntawv nug]. Peb xav xa koj cov ntaub ntawv ntau dua li qhia koj tias peb zoo npaum li cas.
