Lipeipi tsa tšepe tse cheselitsoeng li ka aroloa ka mekhahlelo e meraro ho latela mokhoa oa ho etsa:
1. Motlakase ho hanyetsa welded tšepe pipe
Motlakase ho hanyetsa tjheseletsa phala ea tšepe, lebitso la Senyesemane ERW (Motlakase oa ho hanyetsa welded Pipe), mofuta oa weld o otlolohile seam.The resistance welding e amohela mokhoa oa ho tjheseletsa khatello ntle le tšepe ea ho tlatsa.Ha ho na ho tlatsoa ha likarolo tse ling ka har'a seam weld.Phello ea letlalo le phello e haufi ea maqhubu a phahameng a maqhubu a hona joale a etsa hore moeli oa poleiti o futhumale hang-hang ho mocheso oa tjheseletsa, 'me ho qhekella ho thehoa ka ho penya extrusion roller.Tishu e cheseletsa.
Resistance welded tšepe phala ka aroloa ka mekhahlelo e 'meli: phahameng maqhubu a ho hanyetsa tjheseletsa HFW (High maqhubu welded phala) le tlaase maqhubu khanyetso tjheseletsa tjheseletsa LFW (Low maqhubu tjheseletsa).

2. Spiral welded steel pipe
Spiral welded steel pipe, lebitso la Senyesemane SSAW (Spiral submerged-arc welding pipe), mofuta oa weld ke seam spiral.Mokhoa oa ho kenya li-arc welding o amoheloa, 'me likarolo tse peli tse ka hare le tse ka ntle li kenngoa.Ho tjheseletsa arc ka tlas'a metsi (ho kenyeletsoa ka holim'a metsi a ka tlas'a metsi le electroslag surfacing, joalo-joalo) ke mokhoa oa bohlokoa oa ho tjheseletsa, o nang le melemo ea boleng bo tsitsitseng ba ho tjheseletsa, tlhahiso e phahameng ea welding, ha ho khanya ea arc le mosi o monyenyane le lerōle.
Pipe e nang le spiral welded e na le bophara bo boholo, bo ka fihlang ho feta 3000mm, 'me e loketse haholoanyane bakeng sa lipalangoang tsa liphaephe tsa bophara bo boholo le mehaho ea mohaho.
E meraro, e otlolohileng seam welded tšepe pipe
Pipe e Longitudinally Submerged Arc Welded, lebitso la Senyesemane ke LSAW (Longitudinally Submerged Arc Welded Pipe), 'me mofuta oa weld o otlolohile.Mokhoa oa ho tjheseletsa arc ka tlas'a metsi o boetse o sebelisoa, 'me likarolo tse peli tse ka hare le tse ka ntle li kenngoa.Botenya ba lebota la phaephe ea tšepe ea seam e otlolohileng e batla e le khōlō, 'me tšebeliso ea eona e tšoana le ea pipe ea tšepe e entsoeng ka spiral welded.
Ho latela mekhoa e fapaneng ea ho theha, liphaephe tsa tšepe tse otlolohileng tsa seam seam li ka aroloa ka mekhahlelo e 'meli: UOE (Uing le Oing forming pipe) le JCOE (J-ing, C-ing le O-ing pipe).Mokhoa oa ho etsa UOE (U theha, O ho etsa, katoloso ea bophara ba E), mokhoa oa ho etsa JCOE (poleiti ea tšepe e hatelloa ka sebopeho sa J, ebe e hatelloa ho sebopeho sa C le sebopeho sa O ka ho latellana, ebe se atolosoa).
Re lokela ho hlokomela hore submerged arc welding process (SAW) ke mofuta oa tjheseletsa fusion ea motlakase (EFW Electric Fusion Welded Pipe), e leng ho kopanya tšepe ka ho futhumatsa tšepe pakeng tsa li-electrode tse le 'ngoe kapa tse' maloa tse ka sebelisoang le workpiece.E 'ngoe ea mekhoa eo arc e qhibilihisang tšepe ka ho feletseng le thepa ea ho tlatsa ntle le khatello,' me karolo ea tšepe ea ho tlatsa e tsoa ho li-electrode.
