Enwere ike kewaa ọkpọkọ ígwè welded n'ụzọ atọ dịka usoro nhazi:
1. Electric iguzogide welded ígwè ọkpọkọ
Electric iguzogide welded ígwè anwụrụ, English aha ERW (Electric eguzogide welded Pipe), weld ụdị bụ ogologo onuete.Mgbado ọkụ na-eguzogide na-anabata usoro ịgbado ọkụ na-enweghị igwe ndochi.Enweghị ndochi nke ihe ndị ọzọ na akwa weld.Mmetụta akpụkpọ ahụ na mmetụta nso nso nke elu-ugboro ugbu a na-eme ka nsọtụ efere ahụ dị ọkụ ozugbo na okpomọkụ nke ịgbado ọkụ, na-emepụta ihe na-emepụta site na ịpịnye ihe mkpuchi extrusion.Anụ ahụ weld.
Iguzogide welded ígwè ọkpọkọ nwere ike kewara abụọ edemede: elu ugboro iguzogide ịgbado ọkụ HFW (High ugboro welded anwụrụ) na ala ugboro iguzogide ịgbado ọkụ LFW (Obere ịgbado ọkụ).
A na-ejikarị ọkpọkọ ígwè ERW na-ebufe vepo na ihe mmiri mmiri dị ka mmanụ na gas, ma nwee ike izute ihe dị iche iche chọrọ nke elu na obere nrụgide.Ka ọ dị ugbu a, ha na-anọ n'ọnọdụ dị mkpa na mpaghara nke ọkpọkọ ụgbọ njem na ụwa.
2. Spiral welded ígwè ọkpọkọ
Ọkụ nchara agbadoro agbadoro, aha bekee SSAW (Spiral submerged-arc welding pipe), ụdị weld bụ okirikiri okirikiri.A na-anakwere usoro ịgbado ọkụ nke submerged arc, na n'ime na mpụta okpukpu abụọ na-agbado.Submerged arc ịgbado ọkụ (gụnyere submerged arc surfacing na electroslag surfacing, wdg) bụ ihe dị mkpa ịgbado ọkụ usoro, nke nwere uru nke kwụsiri ike ịgbado ọkụ àgwà, elu ịgbado ọkụ arụpụtaghị, dịghị arc ìhè na obere anwụrụ ọkụ na ájá.
Ọkpụkpọ welded spiral nwere nnukwu dayameta, nke nwere ike iru ihe karịrị 3000mm, ma dabara adaba maka ụgbọ njem pipeline buru ibu na ihe owuwu ụlọ.
Atọ, ogologo onuete welded ígwè ọkpọkọ
Ọdụdọ Arc Welded Pipe Longitudinally Submerged Arc Welded Pipe, aha bekee bụ LSAW (Pip Welded Pipe Long Submerged Arc Welded Pipe), na ụdị weld bụ eriri kwụ ọtọ.A na-ejikwa usoro ịgbado ọkụ nke submerged arc, na ime na mpụta okpukpu abụọ na-agbakọ.Ọkpụrụkpụ mgbidi nke ọkpọkọ nchara kwụ ọtọ dịtụ ukwuu, ojiji ya dịkwa ka nke ọkpọkọ igwe anaghị agba nchara.
Dị ka dị iche iche akpụ usoro, ogologo onuete welded ígwè ọkpọkọ nwere ike kewaa abụọ edemede: UOE (Uing na Oing akpụ ọkpọkọ) na JCOE (J-ing, C-ing na O-ing anwụrụ).UOE akpụ usoro (U na-akpụ, O-akpụ, E dayameta mgbasa), JCOE akpụ usoro (steel efere na-agbanye n'ime J udi, wee pịa n'ime C udi na O udi n'aka, wee gbasaa).
Ekwesiri iburu n'uche na usoro ịgbado ọkụ nke submerged arc (SAW) bụ ụdị ịgbado ọkụ eletrik (EFW Electric Fusion Welded Pipe), nke bụ ijikọta ọla site na ikpo ọkụ n'etiti otu ma ọ bụ ọtụtụ electrodes consumable na workpiece.Otu n'ime usoro nke arc na-agbaze n'ụzọ zuru ezu na ígwè na ihe na-emepụta ihe na-enweghị nrụgide, na akụkụ nke ihe mkpuchi na-abịa site na electrodes.
