X42 ssaw yeeb nkab weldal welded raj
Qhia:
Hauv tshav pob ntawm cov kav hlau hlau, ntau hom vuam siv tau siv los ua tiav cov kev sib txuas zoo thiab txhim khu kev qha. Ib txoj kev ntawd yogMuab kauv submerged arc vuam(Pom), uas ua si lub luag haujlwm tseem ceeb hauv kev tsim cov x42 ssaw cov yeeb nkab. Raws li tus thawj coj ntawm kev ua lag luam, cangzhou kauv steel yeeb nkab polit) Qhov zoo ntawm kev siv kauv submerged arc vuam hauv kev tsim cov yeeb nkab welded.
Kawm txog kauv submerged arc vuam (pom):
Muab kauv submerged arc vuam, tseem hu ua pom, yog ib txheej txheem vuam tshwj xeeb siv los ua cov kav hlau welded xws liX42 ssaw cov yeeb nkabCov. Cov txheej txheem cuam tshuam txog melting cov hlau flux thiab lub hauv paus hlau siv cov cua sov tsim los ntawm cov xaim hluav taws xob thiab flux hauv qab txheej flux. Cov txheej txheem flux ua raws li kev tiv thaiv kev tiv thaiv, tiv thaiv cov paug ntawm cov khoom tsis sib xws los ntawm kev cuam tshuam nrog cov txheej txheem solding. Tus qauv no muaj ob peb qhov zoo dua lwm cov txheej txheem vuam.

Hydrostatic Kev Ntsuam Xyuas
Qhov zoo ntawm kauv submined arc vuam:
1. Cov qauv zoo nkauj thiab muaj txiaj ntsig zoo wels: Cov qauv pom siv hauv x42 ssaw cov yeeb nkab tsim cov khoom siv zoo thiab cov khoom ua haujlwm zoo. Thaum lub arc yog subsmerged nyob rau hauv flux, nws tsim ib qho kev tswj hwm ib puag ncig uas tiv thaiv cov cam los ntawm sab nraud cov ntsiab lus, kom ua tau raws li cov pob qij txha sab nraud. Qhov txiaj ntsig no tau tsim los ntawm cov kauv welded kav hlau nrog kev muaj zog thiab kav ntev.
2. Nce efficiency: kauv submerged arc vuam muaj cov peev xwm tseem ceeb vim nws lub zog hluav taws xob. Cov txheej txheem cuam tshuam, tsis siv neeg pub mis ntawm lub vuam hlau, ua rau cov khoom lag luam sai dua thaum tswj qhov tseeb. HEEV Depepition Cov Nqi thiab Minimal Txawj Ntse ntawm Kev Tuav Kev Ua Haujlwm pab txhawb rau kev ua tau zoo thiab raug nqi zoo.
3. Haum rau ntau qhov kev siv: x42 ssaw yeeb nkab tsim los ntawm kauv submerged arc vuam yog dav siv nyob rau hauv ntau qhov kev lag luam. Cov kav dej no tau siv hauv cov roj thiab roj pipelines, lub tsev dej kev txhawb nqa, cov hauv paus piling, thiab ntau dua. Cov versatility thiab kev ntseeg tau ntawm X42 ssaw raj ua rau nws zoo tagnrho rau cov ntawv thov tseem ceeb.
4. Txhim kho cov khoom siv neeg kho tshuab: Cov qauv pom kom tswj tau zoo dua ntawm kev tswj cov vuam thaum lub sij hawm X42 muab kauv arded arc welded kav. Qhov kev tswj hwm no tuaj yeem txhim kho cov khoom siv tshuab, suav nrog kev cuam tshuam nyuaj, tawm los lub zog thiab tensile lub zog. Raws li qhov tshwm sim, cov kav dej no tau ua rau sab nraud sab nraud thiab yog qhov tsim nyog txawm tias muaj ib puag ncig hnyav.
Hauv kev xaus:
Thaum peb tshawb nrhiav lub ntiaj teb ntawm kev kauv submerged arc vuam hauv x42 ssaw yeeb nkab ntau lawm, vim li cas cov txheej txheem no tau siv nyob rau hauv kev lag luam steel. Muab kauv submerged arc vuam muab ntau yam zoo xws li Weld cov khoom siv roj av, kom tau txais cov khoom siv roj ntsha uas tau ua tiav los ntawm Campzhou KAUV STEED GROUP Co., Ltd., ua tau cov qauv zoo tshaj plaws. Yog li ntawd, nyob rau kev ntseeg tau, ruaj khov thiab ua haujlwm, X42 ssaw raj ua pov thawj kom muaj kev xaiv zoo heev rau ntau yam kev lag luam.
