Hom flange hlau tsis zoo thiab teeb meem xav tau xim
Stainless hlau flange txuas nrog hauv cov yeeb nkab lossis lub cev raj, lub taub hau kawg ntawm lub voj voog ntawm disk, lub disk tusyees faib ib tug xov tooj ntawm lub qhov rooj, qhov feem ntau yog siv yeeb nkab lossis thawv txuas nrog cov chaw tseem ceeb.Yog muaj ntau hom stainless hlau flange , raws li kev siv tau muab faib ua cov yeeb nkab flange (uas yog, yeeb nkab flange) thiab lub nkoj flange siab (khoom flange); Raws li cov duab yuav muab faib ua kab, square, oval thiab tshwj xeeb cov duab ntawm cov hlau tsis flange hlau; Raws li lub siab yuav muab faib ua nruab nrab, tsis tshua muaj siab flange thiab high siab flange; Raws li nws txoj kev txuas nrog cov yeeb nkab lossis lub thauv ntim tau muab faib ua voj vuam tsis muaj hlau flange; Cov hau ntsawb vuam fais fab, taub vuam flange, looj flange, threaded flange thiab flange npog (qhov muag dig muag).
Cov Lus Cim: Yuav kom tsis txhob muaj cov hlau flange npog cua sov thiab qhov muag corrosion, vuam tam sim no yuav tsum tsis txhob loj heev, tsawg dua carbon steel welding pas nrig 20% los yog li, arc yuav tsum tsis dhau ntev, ceev txias ntawm cov khaubncaws sab nraud povtseg, tsim nyog. Lub tshuab electrode yuav tsum ceev kom qhuav thaum siv, titanium calcium yam yuav tsum tau qhuav ntawm 150 ℃ rau 1 teev, qis hom hydrogen yuav tsum tau qhuav ntawm 200-250 ℃ rau 1 teev (tsis tuaj yeem qhuav taus, txwv tsis pub lub txheej yuav yooj yim rau keej thiab tev tawm), los tiv thaiv lub vuam qaum txheej los ntawm cov roj thiab lwm cov av, thiaj li tsis ntxiv cov ntsiab lus ntawm cov vuam seam thiab cuam tshuam rau qhov zoo ntawm cov khoom siv qhov txuas. Thaum steel hlau flange cov yeeb nkab phom yog welded, nws yog rhuab dua rau precipitate carbides, uas thiaj li corrosion kuj thiab mechanical zog.
