Butt-welding flange imwe yemaflange, iyo inoreva flange ine mutsipa uye yakatenderera pombi shanduko uye yakabatana nepombi nebutt welding. Nokuti urefu hwemutsipa hunogona kugoverwa mukatimutsipa butt welding flangeuyemutsipa flat welding flange.
Butt-welding flanges anoshandiswa zvakanyanya nekuti haasi nyore kukanganisa, akavharwa zvakanaka, anoshandiswa zvakanyanya, ane zvinoenderana nekusimba uye elasticity zvinodiwa uye zvine musoro butt welding kutetepa shanduko.
Nekuvandudzwa kwekuvakwa kwepombi refu, butt-welded flange yave chikamu chakakosha chepipeline pressure test. Pamberi uye mushure mekuedzwa kwekumanikidza, chikamu chimwe nechimwe chepombi chinoda kutsvairwa nebhora, nekuwanda kwe4-5 nguva. Kunyanya mushure mekuedzwa kwekumanikidza, zvakaoma kuchenesa mvura mupombi, uye nguva dzekuchenesa dzichawedzera.
Flat welding flange imwe mhando yeflange. Inoshandiswa zvakanyanya uye inosimudzirwa muindasitiri yemuchina, uye yakagamuchira kurumbidzwa uye kufarirwa kubva kune vazhinji vashandisi.
Iyo huru yekushandiswa nharaunda yeflat welding flange yakakodzera, uye iyo chaiyo yekushandisa kukosha uye kuita kweflat welding flange inoda kutariswa zvinoenderana nemamiriro chaiwo. Flange kugadzira iri nyore uye yakaderera mutengo, asi welding basa rakakura, iyo electrode kushandiswa kwakakura, uye haigone kumira tembiricha yakanyanya, kudzvanywa, kudzokororwa kukotama uye kushanduka kwekushisa. Inowanzo shandiswa mapaipi ane PN ≤ 2.5MPa, tembiricha yakajairika, uye tembiricha yekushanda t ≤ 0 ℃.
Imwe yacho ndeyekupinza weld yekunze pakati peflange nepombi, uyezve weld pombi inopinzwa muflange. Iyo pombi uye chiso cheflange chinosungirirwa maererano nezvinodiwa negungano rekudhirowa. Cherechedza kuti chiso cheflange hachigoni kukuvadzwa panguva yekuputika, kana zvisina kudaro kuiswa chisimbiso hakuna kunaka. Iyo welding nzira ndeye manual arc welding, uye welding inodiwa neiyo welding process inogona kushandiswa.
Advantage
Iyo butt-welding flange ine dhizaini inonzwisisika, kusimba kwepamusoro uye kusimba, inokwanisa kumira tembiricha yakakwira uye kudzvanywa kwakanyanya, kudzokororwa kukotama uye kuchinjika kwekushisa, kuita chisimbiso kwakanaka, uye hazvisi nyore kukanganisa. Inoshandiswa zvakanyanya kune mapaipi ane kudzvanywa kukuru kana tembiricha kushanduka kana tembiricha yakakwira, kudzvanywa kwakanyanya uye kuderera kwepombi yekushisa. Mumhuri, iyo dhayamita yepombi idiki, uye yakaderera kudzvinyirira, uye kubatana kwebutt welding flange kusingaoneki. Mukamuri yekubikira kana saiti yekugadzira, kune mapaipi nemidziyo yakabatana nebutt welding flange kwese kwese.
Ndeipi nzira yekugadzirisa butt welding flange?
1. Kugadzira iyo isina chinhu kuita square billet, yozotonhora kukotama kuita arc chikamu, annealing mushure mekupisa kupisa, uyezve kuungana kuita denderedzwa rose pane yakatwasuka lathe kuti igadzirise kune yakagadzirwa chimiro nehukuru;
2. Danho rekutanga nderekutakura kuenda kunzvimbo yekuvaka, uye wozounganidza uye weld akati wandei arc segment kuita akakwana butt welding flanges;
3. Butt-welding flanges ine maitiro akasiyana ekugadzira mukushandiswa nekugadzirwa, uye anogona kugadzirwa uye kushandiswa zvinoenderana neanoenderana zviyero, kuti aone kukosha kwekushandisa uye kushanda kweakasarudzika-akaumbwa flange mukuita.
