Cov qhab nia xaiv tau
- Yog tias cov peev nyiaj tsawg thiab cov dej hauv lub cev tau ua tiav kev kho mob nruj (xws li ntxiv cov tshuaj tiv thaiv corrosion hauv cov dej txias kaw), 1.4003 (ferritic stainless hlau 409L / 3Cr12) yuav raug txiav txim siab; Txawm li cas los xij, nws qhov kev tiv thaiv corrosion yog qis dua, ua rau nws tsis haum rau ib puag ncig nrog cov ntsiab lus chloride siab.
- Rau cov ntawv thov uas muaj cov xov xwm uas tsis tshua muaj corrosivity -xws li cua thiab plua plav tshem tawm ducts lossis cable conduits-1.4016 (430) ferritic stainless hlau yog ib qho kev xaiv, txawm hais tias nws muaj qhov tsis zoo weldability thiab qis zog piv rau austenitic stainless hlau.
- For high-temperature hot water systems (>80℃) lossis cov kab tracing chav, 1.4571 (316Ti) yuav raug txiav txim siab, raws li nws tsim nyog rau lub sijhawm ntev - ua haujlwm ntawm qhov kub txog li 400℃.

FAQ
Q: Puas yog lub zog weld ntawm welded steel kav txhim khu kev qha?
A: Nws yog kiag li txhim khu kev qha. EN 10217-7 tus qauv yuav tsum muaj thaj chaw vuam kom tau txais kev kho mob kom tshem tawm cov kev ntxhov siab ntawm cov vuam seem thiab cov kev hloov microstructural hauv cov cua sov- thaj tsam cuam tshuam. Peb cov khoom ua tiav qhov zoo tshaj plaws ntawm 1.0 (lub ntsiab lus lub zog vuam sib npaug ntawm cov hlau hauv paus), thiab txhua qhov vuam raug txheeb xyuas los ntawm 100% hauv-kab eddy tam sim no kuaj lossis kuaj hydrostatic kom ntseeg tau tias tsis muaj kev pheej hmoo ntawm to.
Q: Dab tsi yog qhov kev khiav hauj lwm kub ntawm cov kav dej?
A: Kev ua haujlwm kub ntau rau 304L / 316L austenitic stainless hlau coiled tubing yog -196℃rau +400℃. Hauv cov ntawv thov HVAC, cov dej txias txias (kuj rau kwv yees li . -10℃nrog glycol daws), cov txheej txheem dej kub thiab dej txias (5-95 degree), thiab cov tshuab dej kub kub (95-150 degree) tag nrho poob rau hauv kev nyab xeeb kev khiav hauj lwm.
Q: Puas yog 316L zoo dua rau 304L rau cov tshuab dej txias?
A: Tsis tas li. Vim nws cov ntsiab lus molybdenum, 316L muaj kev tiv thaiv zoo dua rau hauv zos corrosion los ntawm chloride ions. Txawm li cas los xij, yog tias cov dej tsis zoo thiab ib puag ncig tsis zoo, 304L tuaj yeem ua tau raws li kev ua haujlwm ntawm tus nqi qis.
