Iyo yakakuvadzwa fomu yeLSAW simbi pombi pamusoro

LSAW simbi pombiinoumbwa nepamusoro peiyo yakatetepa uye yakasimba kugadzikana kwefirimu yakanaka yekromium-rich oxide (inodzivirira firimu), kudzivirira kuenderera mberi kwekupinda maatomu eokisijeni, kune oxidation, uye kuwana anti-corrosion kugona.Kana pane chimwe chikonzero, firimu iri raiva kuparadzwa nguva dzose, mhepo kana mvura okisijeni kana simbi maatomu acharamba kupinda simbi atomu kunze kubva nguva dzose kuongorora paumbwe yakasununguka iron oxide, simbi pamusoro ngura achava nguva dzose .Iyi firimu repamusoro muchimiro chekukuvadza kwakawanda, kwakajairika muhupenyu hwezuva nezuva kunopfupikiswa sezvizvi:

1 LSAW simbi pombi pamusoro pedhipoziti chigadzirwa chine mamwe simbi ane guruva zvidimbu kana heterogeneous simbi zvigadziriso mumhepo ine hunyoro, uye simbi isina tsvina pakati pe condensate, izvo zviviri pamwe chete kuita diki-bhatiri, zvichikonzera kemikari yemagetsi kuita, firimu rekudzivirira rakuvadzwa, idaidze kuti electrochemical corrosion.

2 Yakatwasuka pombi pamusoro pekunamira organic muto (semuriwo, soup, sputum, nezvimwewo), okisijeni mubhokisi remvura, inoumba organic acids, organic acids kureba ndiko kuora kwenzvimbo dzesimbi.

3 LSAW simbi pombi pamusoro adhesion ane asidhi, alkali, munyu (senge pamadziro kushongedzwa lye, lime splash), kukonzera localized ngura.

4 mumhepo yakasvibiswa (ine nhamba huru ye sulfide, carbon dioxide, nitrogen oxide atmosphere), nyaya yemvura yakanyungudutswa kuita sulfuric acid, nitric acid, acetic acid solution point, inokonzera kemikari corrosion.

Iyo Yekushandisa Range yeLSAW

.LSAW simbi pombi dhayamita ari pakati 406 ~ 1600mm, mune akasiyana zviitiko kunyange zvakawanda, reshiyo rusvingo ukobvu uye dhayamita pamusoro 0.06 kusvika 0.08.Tekinoroji yemazuva ano yekune dzimwe nyika inogona kuburitsa pombi kusvika 100mm madziro ukobvu wepombi.

Industrial kugadzirwa kwesimbi ndiro kana LSAW simbi nyere chete nzira shoma, musimboti musiyano ndiyo nzira kugadzira simbi pombi, simbi pombi pashure kuumba kutevera-up muitiro zvakangofanana.Misimboti yekugadzira weld inoenderana nekugoverwa kwesimbi, maererano nekugoverwa kwepombi kuti weld maviri akakosha mafomu: yakatwasuka musono uye spiral musono simbi pombi.Zvinoenderana neizvi, yakatwasuka musono yakasungirirwa pombi kugadzirwa mukugadzira uye kugadzirwa kwespiral seam pombi.Yakatwasuka musono uye spiral musono simbi pombi iyo inonyanya kushandiswa nzira inonyudza arc welding (SAW), kunaka kwayo, kugadzirwa kwepamusoro, tekinoroji yakakura uye yakagadzikana.Parizvino, yakatwasuka musono simbi pombi inowanzoshandiswa kunze kwenyika kunotevera siyana: mhepo nyika uye gungwa kutakura, mvura uye mafuta hunde mapaipi;kutakura makemikari uye zvigadzirwa zvemakemikari zvechubhu yesimbi isina tsvina;Marine industrial structure ine chubhu;kugadzirwa kweboiler uye yakakosha chinangwa pombi yemaitiro chubhu.
