Phaephe ea tšepe e tjheseletsoeng e etsoa ka ho sebelisa lipoleiti tsa tšepe tse bataletseng kapa likhoele tsa tšepe, 'me mokhoa oa eona oa tlhahiso o etsa li-seams 'meleng oa eona. Haholo-holo, ha ho etsoa liphaephe tsa tšepe tse tjheseletsoeng, poleiti ea tšepe kapa sekotwana sea kobeha ebe hamorao sea tjheseletsa ka sebopeho sa phaephe e chitja, ea setso kapa sebopeho sa sekwere. Phaephe ea LSAW, phaephe ea SSAW le phaephe ea ERW kaofela ke liphaephe tsa tšepe tse tjheselitsoeng 'me li arotsoe ho latela mokhoa oa ho tjheseletsa. Mohlala, phaephe ea LSAW e tjheseletsa ka bolelele, 'me phaephe ea SSAW e tjheseletsa ka spiral. Phaephe ea ERW ke sheseletsa ea ho hanyetsa motlakase, e leng se fellang ka sekotwana se tsamaeang ka ho lekana 'meleng oa phaephe.

Liphaephe tse nang le maqhubu a phahameng hangata li otlolohile, empa liphaephe tsa tšepe tse nang le maqhubu a otlolohileng ha se hakaalo hore li otlolohile ka maqhubu a phahameng. Phaephe ea tšepe e nang le maqhubu a phahameng e otlolohile ka motlakase e boptjoa ke phello ea letlalo le phello ea bohaufi ba hona joale ea maqhubu a phahameng ka mor'a hore poleiti ea coil e phutholohileng e phutholohileng e thehoe ke mochini oa ho bopa, 'me moeli oa tube e se nang letho o futhumatsoa le ho qhibilihisoa, 'me ho tjheseletsa ka khatello ho etsoa tlas'a ts'ebetso ea rolara e hatellang ho phethahatsa tlhahiso. Phaephe ea tšepe e nang le maqhubu a phahameng e fapane le ts'ebetso e tloaelehileng ea ho tjheseletsa ka phala e phuthetsoeng. Ho tjheseletsa ho entsoe ka thepa ea motheo ea 'mele oa tšepe, 'me matla a mechini a betere ho feta a phala e phuthetsoeng ka kakaretso. Bokaholimo bo boreleli, bo nepahetse haholo, bo theko e tlase, 'me bo na le bophahamo bo tlase ba seam ea ho tjheseletsa, e leng molemo ho ho roala ha 3PE anti-corrosion coating.

Ho tjheseletsa arc e kenelletseng ka nako e telele ho hlahiswa ka ho sebedisa poleiti e le nngwe e mahareng le e teteaneng e le thepa e tala, ho tobetsa (ho pitikisa) poleiti ya tshepe ka hara hlobo kapa mochini wa ho etsa hore e be tube e se nang letho, ho sebediswa ho tjheseletsa arc e kenelletseng ka mahlakore a mabedi, le ho atolosa bophara. Palo ya phepelo ya poleiti ya tshepe e ka fetolwa ka boiketsetso ho ya ka dikereiti tse fapaneng tsa tshepe, botenya ba lebota, le bophara ba poleiti. Ka nako e ts'oanang, mosebetsi wa puseletso ya deformation o qoba ka katleho ditlamorao tse mpe tsa deformation ya hlobo hodima ho bopa mme o netefatsa hore bolelele bohle ba poleiti ya tshepe bo bataletse nakong ya tshebetso ya ho hatella. Mohato wa ho fepa o tshwana nakong ya ho bopa, ho netefatsa hore tube e se na letho le chitja le hore bohale ba welding bo bataletse. Sehlahiswa se fedileng se na le mefuta e mengata ya di-specifications, mme weld e na le ho tiya ho hotle, plasticity, ho tshwana, le ho ba bokgutshwane. E na le melemo ya bophara bo boholo ba phala, botenya ba lebota la phala, ho hanyetsa kgatello e phahameng, ho hanyetsa mocheso o tlase, le ho hanyetsa mafome ka matla.

Phaephe e welletsoeng ka spiral (phaephe ea SSAW, eo hape e bitsoang phaephe ea HSAW). Phaephe e entsoe ka theknoloji ea ho wellisa arc e kenelletseng ka spiral. Liphaephe tse welletsoeng ka spiral li etsoa ka ho sebelisa lipoleiti tse tšesaane kapa likhoele tse phutholohileng tse chesang, e leng se fokotsang litšenyehelo tsa tlhahiso ea tsona haholo. Mohala oa ho wellisa o bōpehile joaloka helix. Ts'ebetso ea ho wellisa ka spiral e lumella tlhahiso ea liphaephe tse bophara bo boholo tse loketseng ho tsamaisa oli le khase tse ngata. Liphaephe tse ling tsa SSAW li ne li lekanyelitsoe ho lits'ebetsong tsa khatello e tlase.
