Ob yam khoom sib txawv tau muag hauv lub npe no - Paub qhov koj tab tom yuav
Qhov no tsim nyog hais ua ntej lwm yam, vim tias nws yog ib qho tseem ceeb tshaj plaws ntawm kev tsis meej pem (thiab qee zaus qhia tsis tseeb) hauv cov khoom lag luam no. "Galvanized ERW yeeb nkab" tuaj yeem txhais tau ob yam sib txawv nyob ntawm kev tsim khoom:
- Weld-ces-galvanize:liab qab steel kauj yog hlais, yob- tsim, thiab hluav taws xob-kuj welded rau hauv cov yeeb nkab ua ntej; cov yeeb nkab tiav lawm ces kub -dip galvanized ua ib daim tiav, sab hauv thiab tawm. Qhov no yog txheej txheem them los ntawmASTM A53Hom E thiab cov qauv zoo sib xws.
- Galvanize-ces-weld:steel kauj yog galvanized ua ntej (ntawm ib tug nruam sawb-galvanizing kab), thiab pre-coated strip yog ces tsim thiab welded rau hauv yeeb nkab tom qab. Lub vuam nws tus kheej kub nyhiab ntawm zinc nyob rau ntawm lub seam, thiab tshwj tsis yog tias cov seam yog nyias nyias, cov yeeb nkab muaj nyias, tsis muaj kev tiv thaiv - lossis tsuas yog maj mam tiv thaiv - kab khiav nws tag nrho ntev raws nraim qhov corrosion feem ntau yuav pib.
Ob leeg raug muag raws li "galvanized ERW yeeb nkab," thiab ob qho tib si siv tau, tab sis lawv tsis hloov pauv rau txhua yam uas cov seam yog qhov kev txhawj xeeb tiag tiag (faus, ntub dej, lossis lwm yam xav tau kev pabcuam). Ib tus neeg muag khoom uas tsis tuaj yeem qhia meej meej tias qhov twg lawv cov khoom raws li hauv qab no yog tus neeg muag khoom tsim nyog nias rau cov lus teb ncaj qha ua ntej xaj.
Yuav Ua Li Cas Weld-Tom qab ntawd- Galvanize ERW Yeeb Nkab Ua tau tiag tiag
- Kub- los yog txias- dov steel kauj yog hlais mus rau qhov dav thiab yob- ua rau cov duab cylindrical.
- Lub seam yog kaw los ntawm hluav taws xob kuj welding (siab- zaus induction los yog hu rau vuam), ua ib tug nruam longitudinal weld.
- Cov yeeb nkab welded raug txiav kom ntev, thiab - rau cov yeeb nkab uas yuav tsum tau muag dub - tej zaum yuav nres ntawm no.
- Rau cov khoom siv galvanized, cov yeeb nkab tiav (nrog rau cov vuam seam) mus los ntawm kev npaj nto: degreasing, acid pickling kom tshem tawm nplai, thiab fluxing.
- Cov yeeb nkab yog immersed nyob rau hauv ib lub hwj ntawm molten zinc (kwv yees li 450 degree), qhov twg cov hlau nyob rau hauv cov hlau reacts nrog zinc los ua ib tug metallurgically bonded txheej - nrog rau cov weld seam, vim nws yog coated raws li ib feem ntawm cov yeeb nkab tiav es tsis ua ntej vuam.
- Tshaj zinc yog drained, lub txheej txias, thiab cov yeeb nkab raug tshuaj xyuas rau txheej hnyav / thickness thiab uniformity, feem ntau siv Preece (tooj liab sulfate) kuaj rau kev txuas ntxiv mus ntxiv rau thickness gauging.
Vim tias tag nrho cov yeeb nkab - seam suav nrog - mus los ntawm zinc da dej tom qab vuam, txoj kev no muab kev tiv thaiv tiag tiag thoob plaws tag nrho saum npoo, uas yog lub ntsiab lus tseem ceeb los qhia nws dhau ua ntej -galvanized- cov yeeb nkab rau kev thov.
Dab tsi Cold Galvanizing Compound Tsis yog
Txij li qhov no tshwm sim ntau zaus hauv cov lus nug ntawm cov neeg yuav khoom: txias galvanizing compound (zinc - cov xim nplua nuj) yog qee zaum siv los kov cov welds, txiav xaus, lossis cov txheej txheem me me tom qab fabrication - tab sis nws yog xim zaj duab xis, tsis yog metallurgical zinc- hlau daim ntawv cog lus, thiab nws tsis ua qhov sib npaug rau qhov tseeb kub - thaj tsam loj. Nws yog txoj kev kho kom raug cai rau thaj chaw me me; nws tsis yog ib txoj kev tsim khoom, thiab cov yeeb nkab uas yog txias tag-galvanized es tsis kub-dip galvanized yuav tsum tsis txhob sawv cev li kub-dip galvanized khoom.
FAQ
Q: Yog galvanized ERW yeeb nkab tib yam li galvanizedLSAWkav, me me xwb?
A: Lub galvanizing chemistry yog tib yam kub-dip txheej txheem nyob rau hauv ob qho tib si, tab sis ob qhov sib txawv nyob rau hauv lub hauv paus yeeb nkab raug tsim (ERW siv hluav taws xob kuj welding ntawm feem ntau me me - txoj kab uas hla, thinner - phab ntsa coil - noj yeeb nkab; LSAW siv submerged arc welding ntawm qhov loj dua 5} txoj kev loj dua {{4}) LSAW yeeb nkab yog qhov tseem ceeb ib txwm batch-dipped tom qab fabrication muab nws qhov loj me, thaum ERW yeeb nkab yog qee zaum ua los ntawm sawb uas twb galvanized ua ntej vuam, uas tsis yog ib qho kev xaiv tiag tiag ntawm LSAW diameters.
Q: Vim li cas cov vuam seam qee zaum zoo li txawv ntawm qhov seem ntawm cov yeeb nkab ERW galvanized?
A: Yog tias cov yeeb nkab tau galvanized tom qab vuam, qhov sib txawv me me ntawm cov seam feem ntau cuam tshuam qhov sib txawv me ntsis hauv qhov chaw reactivity (steel chemistry variation from the welding heat-affect zone) es the coating defect - thickness testing, not looks, confirms seb nws puas coated. Yog hais tias lub seam zoo nkaus li nyias nyias los yog pom cov hlau raug, qhov ntawd yog ib qho kos npe rau cov yeeb nkab yuav tau welded los ntawm pre-galvanized sawb yam tsis muaj seam kov-up.
Q: Cov galvanized ERW yeeb nkab puas tuaj yeem khoov lossis coiled yam tsis muaj kev puas tsuaj rau txheej?
A: Kub-dip galvanized txheej muaj qee qhov ductility thiab tuaj yeem ua rau nruab nrab, tab sis nruj- vojvoog dabtsi yog khoov tuaj yeem tawg lossis flake zinc- hlau alloy txheej, tshwj xeeb tshaj yog cov txheej txheej nyuaj. ASTM A53 sau tseg tias tsis tu ncua-weld (Type F) yeeb nkab tsis yog tsim rau flanging, thiab cov lus ceeb toom zoo sib xws siv rau nruj bending ntawm cov khoom siv galvanized feem ntau - xyuas cov txheej txheem txheej txheem kev taw qhia es tsis yog xav tias qhov khoov vojvoog muaj kev nyab xeeb rau cov txheej.
Q: Puas yog "pre-galvanized" yeeb nkab pheej yig dua, thiab yog tus chij liab?
A: Nws feem ntau tsis tshua kim, feem ntau vim tias nws siv cov hlua txuas txuas ntxiv -galvanizing (ntau dua, qis dua - cov txheej txheem nqi) ntau dua li tom qab -fabrication batch dipping - uas tsis yog lub cim liab rau cov ntawv thov uas seam corrosion tsis yog ib qho kev txhawj xeeb loj (piv txwv li, qee qhov sab hauv tsev) los yog kev pab cuam luv luv (xws li, qee qhov sab hauv tsev 7}} kev pab cuam lub neej. Nws dhau los ua qhov teeb meem tiag tiag tsuas yog thaum nws muag yam tsis tau tshaj tawm rau daim ntawv thov - faus, ntub dej, qauv, ntev -kev pabcuam-lub neej - qhov kev tiv thaiv tag nrho yog qhov tseem ceeb.
