Qhov tseem ceeb ntawm ASTM A139 hauv Kev Siv Hluav Taws Xob Hluav Taws Xob hauv av
Kauv welded carbon steel yeeb nkab tsim rauASTM A139 Cov khoom lag luamyog tsim tshwj xeeb rau kev siv hauv av xws li kev xa hluav taws xob thiab cov tshuab xa tawm.Cov kav dej no yog tsim los siv cov txheej txheem vuam tshwj xeeb uas tsim cov pob qij txha muaj zog thiab ruaj khov, uas yog ib qho tseem ceeb rau kev tiv thaiv kev kub ntxhov hauv av thiab ib puag ncig cov kav dej no yuav raug rau.

Cov txheej txheem welding siv nyob rau hauv ASTM A139 muab cov yeeb nkab zoo ib yam thiab du sab hauv, uas yog ib qho tseem ceeb los xyuas kom meej cov roj ntws zoo los ntawm cov yeeb nkab.Cov kav dej no kuj muaj nyob rau hauv ntau txoj kab uas hla thiab phab ntsa thicknesses, tso cai rau kev yooj yim hauv kev tsim thiab kev tsim kho kom tau raws li cov kev cai tshwj xeeb ntawm kev xa hluav taws xob lossis kev xa tawm.
Ntxiv nrog rau kev ntseeg tau thiab ua haujlwm ntev, ASTM A139 yeeb nkab muab kev tiv thaiv corrosion, uas yog ib qho tseem ceeb rau kev ua kom muaj kev ncaj ncees mus ntev ntawm cov kav dej hauv av.Cov khoom siv carbon steel siv nyob rau hauv cov kav dej no tshwj xeeb tsim los tiv thaiv corrosion, ua kom cov kav dej nyob twj ywm suab thiab tsis muaj paug rau xyoo tom ntej.
Kev nyab xeeb yog qhov tseem ceeb tshaj plaws hauv kev tsim cov kav dej hauv av.ASTM A139 cov kav dej tau tsim thiab sim ua cov qauv kev lag luam nruj thiab cov lus qhia tshwj xeeb, kom ntseeg tau tias lawv tuaj yeem tiv taus cov teeb meem tshwj xeeb ntawm kev siv hauv av.Qhov no muab cov khoom siv hluav taws xob hluav taws xob, cov tswj hwm thiab cov pej xeem kev thaj yeeb ntawm lub siab paub tias cov kev tsim kho vaj tse uas xa cov roj hluav taws xob muaj kev ntseeg siab thiab nyab xeeb.
Hauv kev xaus, ASTM A139kauv welded carbon steel yeeb nkabplays lub luag haujlwm tseem ceeb hauv kev tsim kho cov kav dej hauv av.Lawv durability, corrosion kuj thiab ua raws li cov qauv kev lag luam ua rau lawv zoo tagnrho rau cov phiaj xwm tseem ceeb xws li qhov no.Thaum nws los txog rau kev ua kom muaj kev nyab xeeb, kev ntseeg siab, thiab kev ua haujlwm ntawm cov pa hluav taws xob xa mus thiab xa tawm, siv ASTM A139 pipeline yog qhov kev txiav txim siab uas tsis tuaj yeem tsis quav ntsej.Los ntawm kev xaiv cov ntaub ntawv tsim nyog rau cov ntawv thov hauv av no, peb tuaj yeem ua kom peb cov khoom siv hluav taws xob ntuj muaj kev nyab xeeb thiab txhim khu kev qha rau ntau tiam neeg tom ntej.
