X42 SSAW Yeeb Nkab Kauv Welded Tube
Qhia:
Hauv kev lag luam ntawm cov kav dej steel, ntau yam kev siv vuam siv los ua kom muaj kev sib txuas zoo thiab txhim khu kev qha.Ib txoj kev zoo li no yogkauv submerged arc vuam(SAW), uas ua lub luag haujlwm tseem ceeb hauv kev tsim cov yeeb nkab X42 SSAW.Raws li tus thawj coj hauv kev lag luam, Cangzhou Spiral Steel Pipe Group Co., Ltd., paub txog nws lub npe Wuzhou, ua raws li cov qauv thoob ntiaj teb thiab xyuas kom meej tias nws cov khoom (xws li X42 kauv submerged arc welded yeeb nkab) ua tau raws li API Spec 5L, ASTM A139, ASTM A252. thiab EN 10219. Nyob rau hauv blog no peb delve rau hauv lub ntiaj teb fascinating ntawm X42 SSAW yeeb nkab, qhia txog qhov zoo ntawm kev siv kauv submerged arc vuam nyob rau hauv zus tau tej cov spirally welded yeeb nkab.
Kawm txog Spiral Submerged Arc Welding (SAW):
Kauv submerged arc vuam, tseem hu ua SAW, yog cov txheej txheem vuam tshwj xeeb siv los tsim cov kav dej sib txuas xws liX42 SSAW tub.Cov txheej txheem cuam tshuam nrog melting cov hlau flux thiab lub hauv paus hlau siv cov cua sov tsim los ntawm arc combustion ntawm cov hlau thiab cov flux hauv qab txheej flux.Cov txheej txheej flux ua raws li kev tiv thaiv kev tiv thaiv, tiv thaiv cov kab mob atmospheric los ntawm kev cuam tshuam nrog cov txheej txheem soldering.Txoj kev no muaj ntau yam zoo dua lwm yam kev siv vuam.

Hydrostatic Test
Qhov zoo ntawm kauv submerged arc vuam:
1. Cov welds zoo ib yam thiab zoo: SAW txoj kev siv hauv X42 SSAW yeeb nkab ua rau cov khoom sib xws thiab zoo welds.Thaum lub arc yog submerged nyob rau hauv flux, nws tsim ib tug tswj ib puag ncig uas tiv thaiv lub soldering cheeb tsam los ntawm sab nraud cov ntsiab lus, kom ntseeg tau zoo ib yam thiab txhim khu kev qha pob qij txha.Qhov no tshwm sim nyob rau hauv zus tau tej cov kauv welded kav nrog tshwj xeeb lub zog thiab durability.
2. Kev ua tau zoo ntxiv: Kauv submerged arc vuam muaj kev ua haujlwm zoo vim nws qhov xwm txheej.Cov txheej txheem cuam tshuam tas mus li, tsis siv neeg pub mis ntawm vuam hlau, uas ua rau muaj kev tsim khoom sai dua thaum tswj xyuas qhov tseeb.Cov nyiaj tso nyiaj siab thiab kev cia siab tsawg kawg ntawm kev ua haujlwm ua haujlwm ua rau muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo.
3. Haum rau ntau yam kev siv: X42 SSAW yeeb nkab tsim los ntawm kauv submerged arc vuam yog dav siv hauv ntau qhov kev lag luam.Cov kav dej no yog siv rau hauv kev thauj mus los ntawm cov roj thiab roj, cov kav dej, kev tsim kho vaj tse, cov hauv paus hauv paus, thiab lwm yam.Qhov ntau yam thiab kev ntseeg tau ntawm X42 SSAW raj ua rau nws zoo tagnrho rau cov ntawv thov tseem ceeb.
4.
