Ho ea ka mekhoa ea tlhahiso, liphaephe tsa tšepe li ka aroloa ka mekhahlelo e 'meli: liphaephe tsa tšepe tse se nang moeli le lipeipi tsa tšepe tse cheselitsoeng.lipeipi tsa tšepe tse cheselitsoeng li bitsoa lipeipi tse cheselitsoeng ka nako e khutšoanyane.
Liphaephe tsa tšepe tse se nang moroko li ka aroloa ka liphaephe tse chesang tse phuthoang tse se nang moroallo, lipeipi tse huloang ka mokhoa o batang, lipeipi tsa tšepe tse nepahetseng hantle, lipeipi tse atolositsoeng tse chesang, lipeipi tse ohliloeng ka serame le lipeipi tse ntšitsoeng ho ea ka mekhoa ea tlhahiso.
Lipeipi tsa tšepe tse se nang seam li entsoe ka tšepe ea boleng bo holimo kapa tšepe ea alloy, 'me e ka ba e chesang e phuthoang kapa e batang (e huloang).
Liphaephe tsa tšepe tse cheselitsoeng li arotsoe ka liphaephe tse cheselitsoeng ka seboping, lipeipi tsa welding tsa motlakase (resistance welding) le liphaephe tse othomang tsa arc tse cheselitsoeng ka lebaka la lits'ebetso tsa tsona tse fapaneng tsa tjheseletsa.Ka lebaka la mefuta ea tsona e fapaneng ea li-welding, li arotsoe ka liphaephe tse otlolohileng tsa seam le lipeipi tse cheselitsoeng ka spiral.Ka lebaka la libopeho tsa bona tsa ho qetela, li arotsoe hape ka liphaephe tse chitja tse cheselitsoeng le liphaephe tse nang le sebōpeho se khethehileng (sekwere, sephara, joalo-joalo).
Liphaephe tsa tšepe tse cheselitsoeng li entsoe ka lipoleiti tsa tšepe tse cheselitsoeng tse phuthoang ka libopeho tse nang le li-tubular tse nang le butt kapa spiral seams.Mabapi le mekhoa ea tlhahiso, li boetse li arotsoe ka liphaephe tsa tšepe tse cheselitsoeng bakeng sa lipalangoang tsa mokelikeli o tlaase, lipeipi tsa tšepe tse tsoetsoeng ka spiral, lipeipi tsa tšepe tse tšetsoeng ka ho toba le lipeipi tse cheselitsoeng ka motlakase.Lipeipi tsa tšepe tse se nang seamless li ka sebelisoa liindastering tse fapaneng joalo ka liphaephe tsa khase ea metsi le liphaephe tsa khase.Liphaephe tse cheselitsoeng li ka sebelisoa bakeng sa liphaephe tsa metsi, liphaephe tsa khase, lipeipi tsa ho futhumatsa, lipeipi tsa motlakase, joalo-joalo.
