Cov dej khib nyiab yog corrosive heev; however, the surface of austenitic stainless steel is capable of forming a dense Cr₂O₃ oxide film, which endows it with excellent corrosion resistance, as well as good plasticity and toughness. Yog li ntawd, nws tuaj yeem tiv taus cov dej khib nyiab chlorinated, kua qaub thiab alkaline pov tseg, thiab lwm yam kev tawm tsam hnyav uas tau ntsib thaum cov txheej txheem kho dej khib nyiab.
Welded stainless hlau yeeb nkab qhia tau zoo heev compatibility thaum lub sij hawm cov khoom siv tu thiab vuam ua hauj lwm, qhov twg phau ntawv shielded hlau arc vuam (SMAW) yog tus qauv siv txoj kev. Cov tub ntxhais welding tsis muaj qib siab ntawm kev tswj hwm; tshwj xeeb, qhov vuam tam sim no qis dua qhov yuav tsum tau ua rau cov pa roj carbon steel (feem ntau 90-110 A rau 3.2 hli electrode), thiab qhov kub ntawm qhov sib cuam tshuam tuaj yeem ruaj khov hauv qab 150 degree. Vuam yog ua los ntawm kev siv ceev, luv- arc txheej txheem; ncej-weld, tsuas yog txias straightening yog yuav tsum tau kho tej deformation, ua cov txheej txheem vuam ob qho tib si yooj yim thiab muaj peev xwm ua tau zoo ib yam, siab - zoo weld profiles.

Cov qhab nia xaiv tau
- Rau cov ntawv thov kev kho cov dej khib nyiab uas muaj cov corrosivity tsawg-xws li cov dej phwj hauv nroog-TP304 tuaj yeem raug xaiv los ua lwm txoj hauv kev rau TP316L. Qhov kev xaiv no muaj cov nqi qis dua, cov yam ntxwv ua haujlwm zoo dua, thiab txo qhov nyuaj ntawm vuam, ua rau nws tsim nyog rau kev yuav khoom ntau thiab siv rau hauv qhov chaw ua haujlwm ib puag ncig.
- Rau cov ntawv thov uas muaj dej hiav txwv lossis dej khib nyiab heev hauv kev lag luam tshuaj, cov ntaub ntawv xws li S32205 lossis 2507 raug pom zoo; cov qib no muaj zog tiv thaiv intergranular corrosion thiab ua tau zoo heev - kub ua haujlwm.
- Rau cov dej khib nyiab uas muaj acidity siab lossis tshuaj lom neeg corrosivity, 904L yog qhov pom zoo xaiv.

FAQ
Q: Cov welded raj puas tuaj yeem tiv taus corrosive wastewater ib puag ncig?
A: Yog. TIG welded seams, ntxiv rau pickling thiab passivation, muab muaj zog corrosion kuj. Kev ua tau zoo yog xyuas los ntawm eddy tam sim no, hydrostatic, thiab IGC xeem.
Q: Yuav ua li cas tswj scaling nyob rau hauv pipelines?
A: Siv lub siab - dej ntws tawm siab (1.0–1.5 MPa) nrog lub tshuab nqus tsev nruab nrab. Rau kev ntsuas hnyav, thov citric acid ntxuav, ces yaug kom huv si kom tiv thaiv corrosion.
Q: Cov kev ua haujlwm zoo li cas yog ASTM A249 raj tsim nyog rau?
A: Haum rau cov khoom siv hluav taws xob thiab cov boilers nyob rau hauv nruab nrab mus rau qhov kub thiab txias, corrosive wastewater/chemical media, thiab ntub-dry cycling ib puag ncig.
