Payipu eziweweeza ku kyuma ekitali kizimbulukuse ziyinza okuba n’ebizibu bingi mu nkola y’okuweta, gamba ng’okusala wansi, obutuli, obutafukirira, enjatika, n’ebirala. Olwo, enjatika za ngeri ki z’omanyi ng’okola welding stainless steel welded payipu?
1. Enjatika eyokya .
Kitegeeza enjatika z’okuweta ezikolebwa ekyuma mu weld ne zone ekosebwa ebbugumu mu kiseera ky’enkola ya welding okutuuka ku bbugumu erya waggulu okumpi ne layini ya solidus. Enkola ez’okuziyiza: zifuga nnyo ebirimu eby’obulabe eby’obulabe nga ekibiriiti ne phosphorus mu payipu eziweweevu ez’ekyuma ekitali kizimbulukuse n’ebikozesebwa mu kuweta, zikendeeza ku buwulize bw’enjatika ez’ebbugumu; Teekateeka eddagala mu kyuma kya weld, okulongoosa weld microstructure, okulongoosa empeke, n’okulongoosa obuveera. okukendeeza oba okusaasaanya eddaala ly’okwawula; Kozesa ebikozesebwa mu kuweta alkaline okukendeeza ku bucaafu obuli mu weld n’okulongoosa eddaala ly’okwawula.
2. Enjatika ennyogovu .
Kitegeeza enjatika ekolebwa ng’ekiyungo ekiweereddwayo kinyogozeddwa okutuuka ku bbugumu erya wansi, ekiyitibwa enjatika ennyogovu. Enkola eziziyiza: Kozesa ebikozesebwa mu kuweta ekika kya low hydrogen, goberera nnyo ebiragiro ebiri mu biragiro nga tonnaba kubikozesa; Ggyako amafuta n’obunnyogovu ku weldments nga tonnaba kuziweta, kendeeza ku hydrogen ali mu weld; Londa enkola ensaamusaamu ey’enkola ya welding n’okuyingiza ebbugumu okukendeeza ku nkola y’okukaluba kwa weld kukolebwako amangu ddala okulongoosa kwa haidrojeni oluvannyuma lw’okuweta okusobozesa haidrojeni okutoloka mu kiyungo ekiweereddwa;
3. Ddamu okubugumya enjatika .
Kitegeeza enjatika ekolebwa oluvannyuma lwa payipu ekoleddwa mu kyuma ekitali kizimbulukuse okuddamu okubuguma mu bbanga erimu ery’ebbugumu (okurongoosa ebbugumu erikendeeza ku situleesi oba enkola endala ey’okufumbisa), eyitibwa Reheat Crack.
Enkola ez’okwetangira: Wansi w’ensonga y’okutuukiriza ebisaanyizo by’okukola dizayini, londa ebikozesebwa mu kuweta eby’amaanyi amatono, olwo amaanyi ga weld ne gabeera wansi okusinga ekyuma ekisookerwako, situleesi eba esumuluddwa mu weld, weewale enjatika mu kitundu ekikoseddwa ebbugumu; okukendeeza ku welding residual stress ne stress concentration; Fuga ebbugumu eriyingira mu payipu eya welding, londa mu ngeri entuufu ebbugumu ly’okusooka okubuguma n’okulongoosa ebbugumu, era weewale ekitundu ekiwuliziganya nga bwe kisoboka.
Payipu eya welded ekoleddwa mu kyuma ekitali kizimbulukuse erina okussaayo omwoyo ku butonde obukyetoolodde mu kiseera ky’okukola, n’okukola ennongoosereza mu budde n’okukola ebiwandiiko. Mu kugatta n’embeera ez’enjawulo eziragibwa abakola payipu eziweeseddwa mu kyuma ekitali kizimbulukuse, . Hangao Tech (Ebyuma bya Seko)s Ekyuma ekikuba payipu ekikoleddwa mu kyuma ekitali kizimbulukuse (high-speed stainless steel steel steel welded line production line tube making) kikozesa enkola ya Seko ey’enjawulo ey’okufuga amasannyalaze okufuga arc ekyusiddwa, erongoosa ennyo obulungi n’omutindo gw’okuweta. Mu kiseera kye kimu, ekizuula ekikyamu eky’amasannyalaze ga eddy kikozesebwa nga kigatta okulondoola bbugwe ow’omunda owa payipu eya welded ekiseera kyonna. Enkola ya PLC ey’amagezi erondoola era n’ewandiika ebikwata ku kukola payipu eya welded mu kiseera ekituufu, olwo amakungula ne galongoosebwa nnyo, bwe kityo ne kikendeeza ku nsaasaanya.
