  Kev piav qhia

Welded steel yeeb nkab yog tsim siv lub tiaj tiaj steel daim hlau lossis steel strips, thiab nws cov txheej txheem tsim khoom tsim cov seams hauv nws lub cev.Tshwj xeeb tshaj yog, thaum welded steel kav yog tsim, ib tug steel phaj los yog sawb yog khoov thiab tom qab ntawd welded rau hauv ib ncig, ib txwm yeeb nkab zoo los yog ib tug square. txoj kev vuam.Piv txwv li, LSAW yeeb nkab yog welded longitudinally, thiab SSAW yeeb nkab yog kauv-welded.ERW yeeb nkab yog hluav taws xob tsis kam welded, uas ua rau lub seam uas khiav mus rau tib lub cev ntawm cov yeeb nkab.

 ERW steel yeeb nkab 

High-frequency welded kav yog feem ntau ncaj-slit, tab sis ncaj-slit welded steel kav tsis tas yuav high-frequency welded.Lub high-frequency ncaj-slit hluav taws xob tsis kam welded steel yeeb nkab yog tsim los ntawm cov tawv nqaij nyhuv thiab qhov sib thooj ntawm cov high-frequency tam sim no tom qab lub kub-dov coil phaj yog tsim los ntawm lub tshuab molding, thiab lub ntug ntawm lub raj dawb paug yog rhuab thiab melted, thiab siab welding yog ua nyob rau hauv qhov kev txiav txim ntawm cov nias rau cov menyuam kom paub qhov ntau lawm.Lub high-frequency kuj welded steel yeeb nkab yog txawv los ntawm cov zoo tib yam welded yeeb nkab vuam txheej txheem.Lub vuam yog ua los ntawm cov khoom siv hauv lub hauv paus ntawm cov hlau sawb lub cev, thiab cov neeg kho tshuab lub zog zoo dua li cov yeeb nkab dav dav.Qhov saum npoo yog du, siab precision, tsis tshua muaj nqi, thiab tsis tshua muaj weld seam qhov siab, uas yog qhov zoo rau cov txheej txheem ntawm 3PE tiv thaiv corrosion.

 LSAW steel yeeb nkab 

Longitudinal submerged arc welded yog tsim los ntawm kev siv ib qho nruab nrab thiab tuab phaj raws li cov khoom siv raw, nias (rolling) steel phaj hauv pwm los yog ua tshuab rau hauv lub raj tsis muaj, siv ob sab submerged arc vuam, thiab nthuav cov kab.Cov hlau phaj pub nyiaj tuaj yeem hloov kho raws li qib steel sib txawv, phab ntsa thicknesses, thiab phaj dav.Nyob rau tib lub sijhawm, qhov kev them nyiaj deformation ua haujlwm tau zoo zam qhov tsis zoo ntawm pwm deformation ntawm kev tsim thiab ua kom lub tiaj tiaj ntawm tag nrho ntev ntawm cov hlau phaj thaum lub sijhawm nias.Cov kauj ruam pub mis yog ib yam thaum lub sij hawm tsim, kom ntseeg tau lub roundness ntawm lub raj dawb paug thiab lub flatness ntawm vuam ntug.Cov khoom tiav lawm muaj ntau yam specifications, thiab cov weld muaj zoo toughness, plasticity, uniformity, thiab compactness.Nws muaj qhov zoo ntawm txoj kab uas hla loj, yeeb nkab phab ntsa thickness, siab-siab tsis kam, tsis kub-resistant, thiab muaj zog corrosion kuj. 

 SSAW steel yeeb nkab

Kauv welded yeeb nkab (SSAW yeeb nkab, kuj hu ua HSAW yeeb nkab).Cov yeeb nkab yog tsim los ntawm kauv submerged arc vuam tshuab.Kauv welded kav yog tsim los siv cov phaj nqaim los yog kub dov coils, uas txo lawv cov nqi ntau lawm.Cov kab vuam zoo li lub helix.Cov txheej txheem spiral welding tso cai rau kev tsim cov kav dej loj uas tsim nyog rau kev thauj cov roj thiab roj ntau ntau.Qee cov kav dej SSAW tau keeb kwm txwv rau cov ntawv thov uas tsis tshua muaj siab.
