Pipe ea tšepe ke morero o sebelisoang ka ho fetisisa oa peipi ea khase. Melemo ea eona e ka sehloohong ke: matla a phahameng, boima bo botle, ho jara khatello ea maikutlo, ho hanyetsa tšusumetso le ho tiisa, polasetiki e ntle, ho chesehela habonolo le ho sebetsa ka mocheso, botenya ba lebota bo bobebe, bo boloka tšepe. Empa khanyetso ea eona e mpe ea kutu, e hloka ho ba le mehato e nepahetseng ea anti-corrosion.

Liphaephe tsa tšepe bakeng sa liphaephe tsa khase motseng o moholo oa phala ea tšepe e se nang seamless le e cheselitsoeng ka mekhahlelo e 'meli. Phaephe ea tšepe e se nang matla e phahameng, empa e fokotsa ts'ebetso ea tlhahiso le litšenyehelo ka phala e nyane ea tšepe ea bophara ba DN200 ka tlase. Mefuta e mengata ea liphaephe tsa tšepe tse cheselitsoeng, welding e ka aroloa ka liphaephe tsa tšepe tse otlolohileng tsa seam le mefuta ea liphaephe tsa tšepe tsa spiral. Har'a bona, ho otlolohile seam welded tšepe phala (eo ka mor'a moo e bitsoang phala e otlolohileng ea seam) e boetse e kenyelletsa phala ea tšepe ea LSAW le phala e phahameng ea maqhubu a ho hanyetsa (RW) phala ea tšepe le mefuta e meng. Spiral welded steel pipe (peipi ea ssaw) ke phala ea spiral seam e habeli e kentsoeng ka tlas'a metsi arc welded (HSAW).

Ts'ebetso ea ho etsa seam le spiral pipe e bapisoa, ea pele e na le molemo oa:
① Ts'ebetso ea tlhahiso ea lipeipi tsa spiral ho fumana hore khatello ea bona e setseng e kholo ho feta phala e otlolohileng ea seam, phala e otlolohileng ea seam e nang le phello e akaretsang ea ts'ebetso e atolositsoeng, khatello e setseng e haufi le zero, athe spiral e sitoa ho etsa sena;

② spiral weld lehlakoreng le fosahetseng haholo-holo ka bophara ba 1.1 ~ 1.2mm, tekanyetso e hloka hore karolo e fosahetseng ea lerako e be ka tlase ho 10% bakeng sa li-tubes tse nang le marako a tšesaane, lehlakore le fosahetseng le thata ho finyella litlhoko tse tloaelehileng, le pipe e otlolohileng ea seam ha e eo Bothata bona;

③ Ha ho bapisoa le phaephe e otlolohileng ea seam, phallo ea spiral weld line e fokola, khatello e matla ea khatello ea maikutlo;

④ sebaka se amehileng ke mocheso oa coil se seholo ho feta phala ea seam e otlolohileng, 'me sebaka se amehileng ke mocheso ke senotlolo sa boleng;

⑤ spiral geometry ho nepahala, ho ea setšeng sa kaho, joalo ka molekane, welding e tlisa mathata.
