Peb cov kav dej kauv yog tsim los ntawm cov hlua steel coils los ntawm kev siv ob-xaim ob-sided submerged arc vuam txheej txheem.Los ntawm qhov kub thiab txias extrusion molding tshuab, peb xyuas kom meej tias txhua lub raj yog tsim nrog siab precision thiab sib xws.Cov txheej txheem tsim khoom zoo no ua kom ntseeg tau tias peb cov khoom ua tau raws li cov qauv zoo tshaj plaws, ua rau lawv zoo tagnrho rau ntau yam kev siv.
Piv nrog rau cov kav dej welded,S235 J0 kauv steel yeeb nkab muaj cov yam ntxwv tseem ceeb hauv qab no:
A. Thaum lub sij hawm tsim cov txheej txheem, cov hlau phaj deforms tusyees thiab muaj kev ntxhov siab tsawg kawg nkaus.Tsis tsuas yog qhov no ua rau lub neej ntev ntawm cov yeeb nkab, nws tseem ua kom cov yeeb nkab nto du thiab tsis muaj khawb los yog qhov tsis xws luag.
b.Peb cov txheej txheem ob-sided submerged arc vuam txheej txheem ua kom cov vuam vuam hauv qhov zoo tshaj plaws.Qhov no txo qhov tshwm sim ntawm qhov tsis xws luag xws li misaligned npoo, vuam deviations, thiab vuam tsis tiav.Yog li ntawd, peb cov kav dej muaj cov vuam zoo heev, yooj yim los tswj thiab xyuas kom muaj kev ua tau zoo.
C. Zoo yog peb qhov tseem ceeb tshaj plaws.Yog li ntawd, peb ua tiav 100% kev soj ntsuam zoo ntawm txhua cov yeeb nkab steel peb tsim.Qhov kev tshuaj ntsuam xyuas no tau lees paub tias peb cov kav dej ua tau raws li cov qauv kev lag luam siab tshaj plaws, muab kev thaj yeeb rau koj hauv kev tsim khoom thiab siv cov txheej txheem.
Ntawm Cangzhou Spiral Steel Pipe Group Co., Ltd., peb zoo siab heev rau kev tsim khoomS235 J0 Kauv Hlau Yeeb.Peb nyob hauv Cangzhou City, Hebei Xeev thiab tau ua haujlwm rau kev lag luam txij li xyoo 1993. npog thaj tsam ntawm 350,000 square metres thiab tag nrho cov cuab tam ntawm 680 lab yuan, nws tau tso lub hauv paus ruaj khov rau kev tsim khoom zoo heev.Peb pab neeg mob siab rau ntawm 680 tus neeg ua haujlwm txawj ua haujlwm tsis tu ncua kom ntseeg tau tias tsis muaj seamless ntau lawm thiab xa khoom raws sijhawm ntawm 400,000 tons ntawm kauv steel kav txhua xyoo.
