Steel Pipe Mill yog qhov chaw tseem ceeb hauv kev tsim khoom ntawm txhua lub teb chaws. Nws yog siv los tsim cov kav hlau zoo nkauj uas yog qhov tseem ceeb hauv ntau yam xws li kev tsim kho, mining, roj thiab roj, dej, thiab lwm yam. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov txheej txheem ntawm cov kav hlau steel thiab qhov tseem ceeb ntawm cov yeeb nkab steel mills hauv kev lag luam thoob ntiaj teb.
Kev tsim cov yeeb nkab steel pib nrog kev yuav khoom ntawm cov khoom siv raw, feem ntau yog hlau ore thiab cov khoom seem hlau. Tom qab ntawd cov ntaub ntawv raw yog melted nyob rau hauv ib lub qhov cub kub thiab muab pov rau hauv ingots los yog slabs. Tom qab ntawd cov hlau molten yog dov rau hauv cov ntawv los yog daim hlau uas siv lub tshuab dov.
Cov kauj ruam tom ntej hauv cov txheej txheem tsim khoom yog lub pob zeb tho. Ntawm no, cov nplooj ntawv los yog daim hlau yog pierced siv yob los yog xuas nrig ntaus los tsim ib lub tog raj kheej hollow. Cov npoo ntawm lub tog raj kheej yog ces welded thiab cov seam yog flattened los ua ib lub raj. Lub raj yog ces straightened thiab txiav mus rau qhov xav tau ntev.
Cov kauj ruam kawg hauv cov txheej txheem ntau lawm yog kev ua tiav zeb. Ntawm no, sab nrauv ntawm lub raj yog ua tiav kom tiav qhov yuav tsum tau muaj qhov ntev, cov duab, thiab qhov chaw tiav. Sab hauv txoj kab uas hla kuj tseem tuaj yeem ua tiav kom ntseeg tau tias cov dej ntws zoo.
Steel Pipe Mills ua lub luag haujlwm tseem ceeb hauv kev lag luam thoob ntiaj teb. Lawv muab cov kav hlau steel rau ntau yam kev lag luam uas siv rau ntau lub hom phiaj. Piv txwv li, hauv kev tsim kho kev lag luam, cov kav dej steel yog siv rau kev siv dej thiab cov kav dej, nrog rau kev txhawb nqa hauv paus. Hauv kev lag luam roj thiab roj, cov kav dej steel yog siv rau kev thauj mus los ntawm cov roj thiab roj. Cov yeeb nkab mills kuj tseem ua rau cov khoom siv rov ua dua tshiab, uas pab txo cov khib nyiab thiab tiv thaiv ib puag ncig.
