ASTM A333 GR. 6 Cov Qauv Kub- dov Weld Steel Yeeb Nkab

Taw qhia rau ASTM A333 GR . 6

ASTM A333 GR. 6 carbon steel welded yeeb nkab yog hais txog ib hom carbon steel yeeb nkab ua raws li ASTM A333 GR 6 tus qauv. Cov txheej txheem no qhia txog cov kev cai rau seamless thiab welded steel kav siv nyob rau hauv cryogenic ib puag ncig. Qhov kev xaiv "GR 6" qhia tau hais tias cov yeeb nkab yog tsim los ntawm siab - carbon steel kev ua tau zoo haum rau kev siv cryogenic. Cov pa roj carbon steel welded yeeb nkab tsim raws li ASTM A333 GR 6 specifications qhia tau zoo heev cuam tshuam toughness, lub zog, thiab weldability. Cov kav dej no tau siv dav hauv kev lag luam xws li roj thiab roj, petrochemicals, hluav taws xob tsim hluav taws xob, thiab ua kom zoo rau kev thauj cov dej thiab cov pa roj ntawm qhov kub thiab txias li -50 ° F (-45 ° C). Los ntawm ua tau raws li qhov yuav tsum tau nruj ntawm ASTM A333 GR 6, cov pa roj carbon steel welded kav kom ntseeg tau thiab ruaj khov ua haujlwm txawm tias nyob rau hauv qhov hnyav hnyav.

ASTM A333 Qib 6 Welded Yeeb Nkab Cov Txheej Txheem

1. Resistance Welding (ERW) Txheej Txheem: Cov kav dej yog tsim los ntawm kev siv vuam tsis kam (ERW). Ua ntej, cov nplooj ntawv tiaj tus yog txias - ua rau cov duab cylindrical. Tom qab ntawd, cov hlau yog rhuab mus rau qhov kub thiab txias, ua rau cov npoo ntawm cov yeeb nkab los nias ua ke los tsim ib lub vuam seam. Tsis tas yuav tsum tau vuam hlau.

2. Submerged Arc Vuam (SAW) Txheej Txheem: Hauv submerged arc vuam (SAW), tsis tu ncua pub liab qab vuam hlau electrode ua ib qho arc nrog lub workpiece. Flux yog siv los tsim cov roj tiv thaiv, slag, thiab ntxiv cov khoom sib xyaw rau hauv lub pas dej molten. Tsis tas yuav tsum muaj cov roj thaiv kev tiv thaiv. Tshaj dhau flux rov qab los ntawm lub hopper raws li lub arc nce mus raws li cov weld seam. Tom qab vuam, txhua txheej slag seem tau yooj yim tshem tawm. Vim tias cov txheej txheem flux npog tag nrho cov arc, qhov arc feem ntau pom tsis pom thaum lub vuam, thiab qhov kub poob yog tsawg. Piv rau 25% thermal efficiency ntawm phau ntawv arc vuam, txoj kev vuam no tuaj yeem ua tiav cov thermal efficiency txog li 60%.
