Kab lus no muab cov lus qhia dav dav ntawm cov txiaj ntsig tseem ceeb thiab qhov tsis zoo ntawm ERW steel yeeb nkab, txhim kho nrog cov qauv meej thiab cov lus tshaj lij tsim nyog rau cov neeg tuaj saib.
Nkag siab txog ERW Pipe
ERW Pipe yog dab tsi
Hluav taws xob Resistance Welded yeeb nkab yog tsim los ntawm siab - zaus vuam ntawm cov npoo ntawm ib daim hlau dov. Raws li cov sawb yog zoo li tus cylindrical daim ntawv, cov npoo yog rhuab hluav taws xob thiab nias ua ke los tsim ib tug nruam longitudinal seam. Cov yeeb nkab uas ua tau yog feem ntau du sab hauv thiab sab nraud, nrog cov phab ntsa tuab thiab txhim khu kev qha txhua yam khoom.
Yuav Ua Li Cas ERW Pipe
Cov txheej txheem tsim khoom ERW pib nrog siab -cov hlau zoo uas tsis tau dov, theem, thiab maj mam tsim rau hauv cov duab tubular los ntawm ib ntu ntawm kev ua cov yob. Siab - zaus tam sim no yog siv rau ntawm seam kom ua tiav vuam. Ntau cov kab ERW niaj hnub no kuj tseem suav nrog qhov nruab nrab zaus annealing thiab tsis yog-kev sim ua kom puas tsuaj los txhim kho qhov zoo ntawm qhov vuam thiab kev ua haujlwm zoo.
Qhov zoo ntawm ERW Pipe
