ASTM A213 T11 Serrated Finned Tube
ASTM A213 T11 serrated finned tubes yog cov khoom siv hluav taws xob kub uas siv rau ntau yam kev lag luam, tshwj xeeb hauv kev tsim hluav taws xob thiab kev lag luam petrochemical. Cov raj no yog tsim los ntawm ASTM A213 T11 alloy steel, low-alloy steel nrog 1 feem pua -1.5 feem pua chromium thiab 0.5 feem pua -1 feem pua molybdenum. Cov khoom no yog resistant rau high kub thiab high-pressure xwm txheej, raws li zoo raws li corrosion.
Cov txheej txheem vuam ntau zaus yog siv los txuas cov fins rau cov hlab, kom ntseeg tau qhov sib txuas ntawm cov fins thiab cov hlab. Serrated fins nyob rau sab nraud ntawm cov hlab ua kom lub tshav kub hloov mus rau qhov chaw, tso cai rau kev sib pauv cua sov ntawm cov kua dej ntau dua. ASTM A213 T11 serrated finned hlab yog feem ntau siv nyob rau hauv high-temperature thiab siab daim ntaub ntawv xws li boilers, tshav kub exchangers, thiab superheaters. Lawv tau tsim los tiv taus qhov kub thiab txias, ua rau lawv zoo tagnrho rau kev siv hauv qhov hnyav hnyav.

TS tuaj yeem muab ASTM A213 T11 serrated finned hlab nyob rau hauv ntau qhov ntev, nrog rau sab nraud (OD), phab ntsa thickness (WT), thiab lub hauv paus raj ntev (L). OD feem ntau yog nyob nruab nrab ntawm 16mm thiab 273mm, thaum phab ntsa thickness yog nruab nrab ntawm 2.0mm thiab 15.0mm. Qhov ntev ntawm cov raj tuaj yeem hloov kho kom haum rau daim ntawv thov. Cov raj no kuj muaj nyob rau hauv ntau yam fin qhov ntev. Cov serrated fins ntawm cov hlab no feem ntau yog 0.5mm txog 3.0mm tuab thiab 8.0mm txog 35.0mm siab. Fin pitch, lossis qhov kev ncua deb ntawm fins, kuj tuaj yeem hloov kho los txhim kho cov cua sov kom zoo.
ASTM A213 T11 serrated-finned tubes yuav tsum tau kuaj thiab tshuaj xyuas kom paub tseeb tias lawv ua tiav cov qauv kev lag luam. Kev kuaj hydrostatic, kuaj ultrasonic, eddy tam sim no kuaj, thiab kev soj ntsuam pom yog ntawm lawv.
