Cov teeb meem thiab cov kev daws teeb meem rau cov khoom me me ntawm cov xaj zoo
Tus neeg siv khoom South American tau ntsib ob qhov teeb meem loj hauv cov txheej txheem yuav khoom: ib qho yog tias cov kav hlau tsis muaj qhov sib txuas yuav tsum ua tau raws li qhov nrujASTM A53/A53 GR.Bcov qauv; qhov thib ob yog tias qhov ntim khoom ntawm 17 tons tsis tau raws li qhov yuav tsum tau ua ntawm cov hlau cog. Txhawm rau teb rau qhov xwm txheej no, peb lub tuam txhab tau tsim lub network xa khoom sai sai, phim cov peev txheej qhov chaw kom raug, thiab muab cov neeg siv khoom nrog kev daws teeb meem ib zaug xwb los ntawm kev lees paub cov lus qhia mus rau kev xa khoom thaum ua kom ntseeg tau tias cov khoom zoo thiab kev ntseeg siab ntawm hom.

"Rau cov xaj uas muaj lub npe meej thiab cov kev cai zoo, tab sis qhov ntau tsis ua tau raws li qhov txwv ntawm kev xa khoom ncaj qha los ntawm cov chaw tsim hlau, peb qhov txiaj ntsig yog nyob rau hauv kev sib koom ua ke sai ntawm cov peev txheej," peb tus thawj tswj lag luam hais. "A53 GR.B tus qauv seamless steel kav dej siv dav hauv cov teb ntawm roj, roj thiab kev tsim kho, tab sis kev yuav khoom me me feem ntau ntsib cov teeb meem ntawm lub sijhawm xa khoom ntev thiab ob peb txoj kev."

Vim li cas ho xaivASTM A53 GR.Bcov kav hlau tsis muaj seamless?

Kev ntseeg siab ntawm cov khoom siv: GR.B qib carbon steel muaj lub zog tensile siab dua (≥415MPa) thiab tsim nyog rau cov kav dej nruab nrab thiab siab siab

Cov txheej txheem txheej txheem: SCH 40 phab ntsa tuab ua tau raws li feem ntau qhov xwm txheej siab, thiab 12-meter qhov ntev ruaj khov txo cov qhov vuam ntawm qhov chaw

Kev xa khoom sai: 189mm-273mm sab nraud txoj kab uas hla ntau yam npog cov kev xav tau ntawm cov yeeb nkab txoj kab uas hla, thiab cov khoom muag pom tseeb lav qhov kev nce qib ntawm cov haujlwm xwm txheej ceev

Qhov kev koom tes no dua ib zaug ntxiv ua pov thawj peb lub tuam txhab lub peev xwm kev tshaj lij hauv kev muab cov hlau tshwj xeeb me me. Yav tom ntej, peb yuav txuas ntxiv mus txhim kho cov kav hlau tsis muaj seamless thiab muab cov neeg siv khoom thoob ntiaj teb nrog ntau cov yeeb nkab txheem suav nrogAPI 5LthiabASTM A106.
