Welded Yeeb Nkab Supplier-GNEE
1. Resistance welded steel yeeb nkab
Hluav taws xob tsis kam welded steel yeeb nkab, lub npe lus Askiv yog ERW (Electric resistance welded Pipe), hom vuam yog ncaj seam. Resistance vuam siv lub siab vuam txoj kev uas tsis muaj muab tub lim hlau. Tsis muaj lwm yam khoom uas muaj nyob rau hauv lub vuam. Nws tso siab rau cov nyhuv ntawm daim tawv nqaij thiab qhov sib thooj ntawm cov high-frequency tam sim no rau instantly tshav kub ntawm ntug ntawm lub phaj mus rau vuam kub, thiab yog extruded los ntawm extrusion roller los tsim ib tug forging. Cov ntaub so ntswg welds.
Resistance welded steel kav yuav muab faib ua ob pawg: high zaus kuj welding HFW (High zaus welded yeeb nkab) thiab tsawg zaus kuj welding LFW (Low zaus vuam).
ERW steel kav feem ntau yog siv los thauj cov vapor thiab cov khoom ua kua xws li roj thiab roj. Lawv tuaj yeem ua tau raws li ntau yam kev xav tau ntawm kev kub siab thiab qis. Lawv tam sim no tuav txoj haujlwm txiav txim siab hauv thaj chaw ntawm cov kav dej thauj mus los hauv ntiaj teb.
2. Kauv welded steel yeeb nkab
Kauv welded steel yeeb nkab, cov lus Askiv lub npe yog SSAW (Spiral submerged-arc vuam yeeb nkab), hom vuam yog kauv seam. Siv submerged arc vuam txoj kev, ob txheej txheej vuam sab hauv thiab sab nraud. Submerged arc vuam (xws li submerged arc cladding thiab electroslag cladding, thiab lwm yam) yog ib qho tseem ceeb welding txoj kev. Nws muaj qhov txiaj ntsig zoo ntawm kev ruaj khov vuam zoo, vuam tsim tau zoo, tsis muaj lub teeb arc thiab cov pa luam yeeb me me.
Kev tsim txoj kab uas hla ntawm kauv welded yeeb nkab yog loj, uas tuaj yeem ncav cuag ntau tshaj 3000mm. Nws yog qhov tsim nyog rau kev thauj mus los ntawm cov kav dej loj loj thiab cov qauv hauv tsev.
3. Ncaj seam welded steel yeeb nkab
Ncaj seam welded steel yeeb nkab, lus Askiv lub npe yog LSAW (Longitudinally Submerged Arc Welded Pipe), hom vuam yog ncaj seam. Tib submerged arc vuam txoj kev yog siv, nrog ob txheej welding sab hauv thiab sab nraud. Ncaj seam steel kav yog tsim nrog cov phab ntsa loj dua thiab siv zoo ib yam li cov kav hlau welded steel kav.
Ncaj seam welded steel kav tuaj yeem muab faib ua ob pawg raws li cov txheej txheem sib txawv: UOE (Uing thiab Oing sib sau cov yeeb nkab) thiab JCOE (J-ing, C-ing thiab O-ing yeeb nkab). UOE forming method (U forming, O forming, E txoj kab uas hla expansion), JCOE txoj kev (steel phaj yog nias rau hauv J puab, ces nias rau hauv C duab thiab O zoo nyob rau hauv ib theem zuj zus, thiab ces nthuav).
Nws yuav tsum tau muab sau tseg tias submerged arc vuam txheej txheem (SAW) yog ib hom hluav taws xob fusion vuam (EFW Electric Fusion Welded yeeb nkab), uas heats hlau ntawm ib los yog ob peb consumable electrodes thiab lub workpiece los khi cov hlau. Ib tug txheej txheem nyob rau hauv uas lub arc melts cov hlau thiab filling cov ntaub ntawv uas tsis tas yuav tsum tau rau siab. Tag nrho cov hauj lwm ntawm qhov filling hlau yog los ntawm electrode.
