* Astm A213 ** yog tus qauv kev qhia los ntawm Astm International uas npog Seamless Ferritic thiab AVEX BOILER, super {2} {2} {2}- Cov tub rog. Cov hlab yog tsim los rau kev pabcuam hauv high- kub thiab siab}}}}} Cov khoom tseem ceeb hauv kev siv cov kev siv tau.
Cov thawj coj ntawm cov yam ntxwv ntawm cov leeg ua raws li cov qauv no yog lawv ** Seamless entrial tsim **. Lawv tsim los ntawm cov txheej txheem xws li extrusion lossis tho ib lub thawv ntim khoom, uas tsim kev txuas ntxiv mus, homogeneous raj. Qhov kev txwv tsis pub muaj weld kab yog qhov tseem ceeb thaum nws tshem tawm ib qho yuav ua tsis tiav, muab lub zog zoo dua, thiab kev tiv thaiv zoo nyob rau hauv huab cua sov thermal.
Cov kev qhia tshwj xeeb npog tau ntau yam ntawm alloy steels, categorized rau ob pawg neeg tseem ceeb:
* ** Ferritic Alloy Hlau: ** Xws li T5, T9, T11, T22. Cov kawm qib no tau paub txog lawv lub zog siab ntawm lub zog thiab oxidation tsis kam.
* ** Austenitic stainless hlau: ** Xws li SPP304 / 304H, TP316 / 311H, thiab Tp347H. Cov qib no muaj cov qib kev ua tau zoo tshaj plaws thiab zoo dua li - lub zog thiab cov plaw ua haujlwm.
** Cov yam ntxwv tseem ceeb thiab cov kev xav tau ** tseg los ntawm ATM A213 tus qauv suav nrog:
* ** Kev tswj cov tshuaj: ** Kev tswj nruj nruj dhau ntawm cov feem pua ntawm cov ntsiab lus zoo li chromium, molybdenum, thiab npib tsib xee kom ntseeg tau cov khoom uas xav tau.
* ** Cov cuab yeej kho tshuab: ** Guaranteed yam tsawg kawg nkaus rau lub zog tensile thiab kom lub zog.
* ** Hardness Yuav Tsum Tau: ** Cov tawv me me kom ntseeg tau tias cov khoom tsim nyog ua kom muaj zog thiab ductility.
* ** Kev tswj hwm qhov ntev: ** tswj hwm ntawm sab nraud ntawm lub taub, phab ntsa tuab, thiab ntev.
* ** Hydrostatic Kuaj: ** Txhua lub raj yog yuav tsum tau yauv tsis tau ib qho tsis-}} {}}} muaj kev ncaj ncees.
* ** Tsis {- Cov ntawv ntsuas hluav taws xob cuam tshuam nrog EDDY Destray tam sim no lossis kev sim ultrasonic feem ntau ua rau kuaj xyuas qhov chaw thiab cov teeb meem subsurface.
Vim tias cov khoom siv nruj me nyuam no, ** SETM A213 Seamless Tubes ** Yog cov khoom siv ntawm kev xaiv hauv cov ntawv thov tseem ceeb xws li:
* ** Fossil roj thiab lub zog hluav taws xob: ** Rau cov raj boiles, cov ntu tsheb superas, thiab ntu ntu.
* ** PETROCHEMICAL APPLECERMER: ** Hauv kev hloov cua sov, cov hws, thiab cov raj rhaub.
* ** Kev ua lag luam: ** Rau siab -} rauv Cheebtsam thiab siab kub tshuab.
Hauv cov ntsiab lus, Astm A213 txhais cov cim ua haujlwm rau high-}} {{{{{tus neeg sib ceg. Nws cov kev cai ua kom ntseeg tau tias cov khoom muaj peev xwm tsim nyog, kho tshuab, thiab muaj zog nyob hauv lub ntiaj teb no feem ntau tseem ceeb tshaj plaws thermal zog.
