Kauv Submerged Arc Welded Yeeb Nkab Hauv API 5L Kab Yeeb Nkab Daim Ntawv Thov
CovAPI 5L kab yeeb nkabtus qauv yog ib qho kev qhia tshwj xeeb uas tsim los ntawm American Petroleum Institute (API) rau kev thauj mus los ntawm cov roj av, roj thiab dej.Nws qhia txog kev tsim cov khoom siv rau cov kav hlau welded thiab teeb tsa cov txheej txheem nruj rau qhov zoo, lub zog thiab kev ua haujlwm ntawm cov kav dej no.

SSAW tubyog tsim los siv cov txheej txheem submerged arc vuam uas koom nrog kev tsim cov kauj hlau ua ib puag ncig thiab tom qab ntawd siv vuam arc los fuse cov npoo ntawm cov kauj ua ke.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv kauv submerged arc welded yeeb nkab hauv API 5L kab yeeb nkab kev siv yog lawv lub peev xwm los tiv taus siab ntawm sab hauv thiab sab nraud.Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev lag luam roj thiab roj, qhov twg cov kav xa hluav taws xob raug cuam tshuam rau cov xwm txheej hnyav thiab cov khoom hnyav.Kev tsim kho muaj zog ntawm SSAW cov kav dej ua rau nws zoo tagnrho rau cov kav dej ua haujlwm ntawm qhov kub thiab txias, muab cov kev daws teeb meem ruaj khov thiab kav ntev rau kev thauj mus los ntawm cov khoom muaj txiaj ntsig.
Tsis tas li ntawd, qhov yooj yim ntawm kauv submerged arc welded yeeb nkab ua rau nws yooj yim rau nruab thiab tswj, ua rau nws muaj txiaj ntsig zoo rau kev tsim cov kav dej.Lawv lub peev xwm los flex thiab ua raws li lub ntuj contours ntawm struts tshem tawm qhov kev xav tau ntawm cov khoom kim heev thiab siv sij hawm siv rau kev tsim khoom thiab txo qhov kev pheej hmoo ntawm kev xau thiab tsis ua haujlwm.Tsis tas li ntawd, qhov zoo nkauj sab hauv ntawm SSAW cov kav dej txo qis kev sib txhuam thiab turbulence, uas ua rau muaj txiaj ntsig zoo dua thiab siv zog tsawg.

ib.Txoj kev deoxidation yog tsim raws li hauv qab no: FF: Ua tiav cov hlau uas muaj nitrogen khi cov ntsiab lus kom txaus los khi muaj nitrogen (xws li min. 0,020% tag nrho Al lossis 0,015% soluble Al). b.Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj muaj pes tsawg leeg pom qhov tsawg kawg nkaus Al ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al / N piv ntawm 2: 1, lossis yog tias muaj lwm yam N-binding ntsiab.Cov ntsiab lus N-binding yuav tsum tau sau rau hauv Cov Ntaub Ntawv Tshawb Fawb. |
Hauv cov ntsiab lus, kev siv cov kauv submerged arc welded yeeb nkab hauv API 5L kab yeeb nkab daim ntawv thov muaj cov txiaj ntsig zoo uas ua rau nws muaj txiaj ntsig zoo rau kev lag luam roj thiab roj.Lawv lub zog, durability thiab saj zawg zog ua rau lawv zoo tagnrho rau siv nyob rau hauv kev xav tau ib puag ncig, thaum lawv yooj yim ntawm installation thiab tsis tshua muaj txij nkawm yuav tsum tau muab ib tug nqi-zoo tshuaj rau cov kav raj xa dej.Raws li qhov kev thov rau kev txhim khu kev qha, kev thauj mus los zoo ntawm cov roj, roj thiab dej txuas ntxiv, qhov tseem ceeb ntawm cov kauv submerged arc welded yeeb nkab hauv API 5L kab yeeb nkab qauv tsis tuaj yeem overstated.Nrog nws cov pov thawj kev ua tau zoo thiab versatility,kauv submerged arc yeeb nkabtau teeb tsa txuas ntxiv mus ua ib qho tseem ceeb ntawm cov txheej txheem kev lag luam uas tsav lub ntiaj teb kev lag luam.
