SA210 cov raj muaj qhov siab tshaj plaws ua haujlwm kub txog li 1000 degree F (538 degree), uas yog nyob rau hauv nruab nrab ntawm lub pob nyob rau hauv cov nqe lus ntawm kub tsis kam rau boiler raj cov ntaub ntawv.
1. Carbon Steel Tubes (xws li SA179, SA192)
Cov raj no muaj qhov kub zoo sib xws rau SA210, feem ntau ua haujlwm txog li 900-1000 degree (482-538 degree ). Lawv feem ntau siv rau hauv daim ntawv thov zoo sib xws, tab sis tej zaum yuav muaj cov khoom sib txawv me ntsis lossis cov tshuaj muaj pes tsawg leeg.
2. Alloy Steel Tubes (xws li SA213 T11, T22):
Cov ntaub ntawv no tuaj yeem tiv taus qhov kub thiab txias, feem ntau mus txog 1100-1200 degree (593-649 degree ). Lawv muaj me me ntawm cov ntsiab lus alloying, xws li chromium thiab molybdenum, uas txhim kho lawv qhov kub thiab txias zog thiab creep kuj.
3. Austenitic Stainless Steel Tubes (xws li SA213, TP304, TP316):
Stainless hlau raj muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem ua haujlwm ntawm qhov kub txog li 1500-1600 degree (816-871 degree ). Txawm li cas los xij, lawv kim dua cov pa roj carbon steel lossis cov hlau tsis tshua muaj hlau.
4. High Alloy Tubes (xws li Inconel, Incoloy)
Cov ntaub ntawv no yog tsim los rau kev siv kub heev thiab tuaj yeem tiv taus qhov kub siab tshaj 2000 degree F (1093 degree). Lawv yog siv nyob rau hauv tshwj xeeb kub boilers, tab sis tus nqi yog ho ntau dua
Thaum xaiv cov khoom siv boiler tube, engineers yuav tsum sib npaug ntawm cov khoom xws li kev khiav hauj lwm kub, siab, corrosive ib puag ncig, thiab nqi. SA210 boiler raj muab cov kev daws teeb meem zoo rau ntau daim ntawv thov hauv lawv qhov kub thiab txias, muab kev ua haujlwm zoo yam tsis tas siv cov khoom siv kim dua.
Nws yog ib qho tsim nyog sau cia tias thaum SA210 cov hlab tuaj yeem tiv taus qhov kub txog li 1000 degree, lawv lub zog txo qis thaum kub nce.
