Qhov project Overview
Qhov kev hloov kho tshiab tau tsom mus rau kev hloov cov kav dej laus carbon steel uas tau raug kev txom nyem los ntawm:
Sab hauv corrosion
Thermal stress cracking
Cov dej xau vim khov -thaw nthuav dav
Qhov kev daws teeb meem suav nrog muab:
👉 ASTM A409 304L stainless hlau welded kav (20 "SCH10S)
rau lub hauv paus tsev kawm ntawv cov cua sov kis tau tus mob.
Cov Kev Sib Tw Tseem Ceeb Engineering
1. Txias-Thaw Cycle Stress ❄️⚠️
Hauv Canadian huab cua:
Qhov kub thiab txias hloov pauv sai heev
Cov kav dej nthuav dav thiab cog lus dua
Thermal qaug zog ua rau tawg
👉 Cov khoom siv tsis zoo nyob rau hauv lub voj voog kev ntxhov siab
2. Corrosion nyob rau hauv cov cua kub cua tshuab
Cov dej kub hauv Cheeb Tsam muaj:
Dissolved oxygen
Tshuaj kho mob additives
Moisture -induced corrosion yam
👉 Carbon steel pipelines qhia:
Rust tsim
Kev ntsuas sab hauv
Txo cov hluav taws xob hloov hluav taws xob
3. Ntev-Nyob deb ntawm tshav kub kis
Kev sib txuas hauv nroog loj yuav tsum muaj kev ruaj khov
Kev poob siab yuav tsum raug txo kom tsawg
Thermal efficiency yog qhov tseem ceeb
4. Tus nqi tu thiab nqi qis 💰
Kev kho cov kav dej hauv av yog kim heev
Lub caij ntuj no tsis ua haujlwm txaus ntshai yog qhov tseem ceeb
Ntev lifecycle yuav tsum tau (15-25 xyoo)
