Peipi ea tšepe e entsoeng ka tšepe e entsoe ka lipoleiti tsa tšepe tse bataletseng kapa likhoele tsa tšepe, 'me ts'ebetso ea eona ea tlhahiso e etsa seams' meleng oa eona.Haholo-holo, ha ho etsoa lipeipi tsa tšepe tse cheselitsoeng, poleiti ea tšepe e kobeha 'me ka mor'a moo e cheselletsoa hore e be selikalikoe, sebopeho sa peipi ea setso kapa sebopeho sa lisekoere. LSAW pipe, SSAW pipe le ERW pipe kaofela ke lipeipi tsa tšepe tse cheselitsoeng 'me li khethiloe ho ipapisitsoe le mokgoa wa ho tjheseletsa.Mohlala, phala ea LSAW e cheselitsoe ka nako e telele, 'me phala ea SSAW e entsoe ka spiral-welded.Pipe ea ERW ke motlakase o hanyetsanang le welded, e leng se etsang hore ho be le seam e tsamaisanang le 'mele oa phala.

Spiral welded pipe (SSAW pipe, eo hape e bitsoang HSAW pipe).Pipe e entsoe ka theknoloji ea spiral submerged arc welding.Liphaephe tse cheselitsoeng ka spiral li thehoa ho sebelisoa lipoleiti tse moqotetsane kapa li-coil tse chesang tse chesang, tse fokotsang litšenyehelo tsa tlhahiso ea tsona haholo.The tjheseletsa line sebopeho joaloka helix.Ts'ebetso ea spiral welding e lumella ho hlahisoa ha lipeipi tse bophara bo boholo tse loketseng ho tsamaisa oli le khase e ngata.Liphaephe tse ling tsa SSAW li ne li lekanyelitsoe historing ho likopo tsa khatello e tlaase.
