Loj txoj kab uas hla dej tej yaam num feem ntau xav tau cov yeeb nkab seem uas muaj peev xwm txaus thiab cov nqi ntau lawm. Kauv welded yeeb nkab yog siv nyob rau hauv ntau yam khoom siv dej, kua dej, dej phwj tuaj kho, irrigation, thiab kev tsim kho hauv nroog. Cov ntaub ntawv siv piav qhia tias txoj kab uas hla loj kauv yog feem ntau siab dua 1 meter inch, thiab DN2500 yeeb nkab yuav muaj qhov tseeb sab nraud ntawm 2500 thiab 2520 mm. Phab ntsa thickness tuaj yeem nyob ntawm 8 hli mus rau 25 hli lossis tuab dua.
Txoj kev tsim khoom pib nrog steel kauj. Lub sawb yog leveled, trimmed, thiab tsim los ntawm rollers, thiab qhov sib txawv weld yog tswj ua ntej vuam. Muab ob npaug -hlau, ob npaug -sided submerged arc vuam pab kom ruaj ntseg seam. Rau cov yeeb nkab loj, kev tshuaj xyuas vuam tseem ceeb vim tias txoj hlua ntev khiav los ntawm txhua ntu ntawm cov yeeb nkab. Kev kuaj ultrasonic online thiab kev ntsuas siab tuaj yeem suav nrog raws li qhov project.
Rau ib txoj kab dej, tus neeg yuav khoom yuav tsum paub meej hauv txoj kab uas hla, phab ntsa thickness, ntev, steel khoom, txheej xav tau, thiab daim ntawv kawg. Qee cov kab xav tau tsuas yog thauj lub zog, thaum lwm tus xav tau kev tiv thaiv- txheej txheej lossis kev tiv thaiv sab hauv. Yog tias cov yeeb nkab yuav raug siv rau hauv txoj kev faus, av thiab kev kho mob sib koom yuav tsum tau txiav txim siab ua ntej kev tsim khoom kawg.
