Ts'ebetso ea tlhahiso ea mofuta ona oa lipeipi tsa tšepe e kenyelletsa ho tsoela pele ho crimping lipoleiti tsa tšepe hore li be sebopeho sa spiral le ho tjheseletsa mathōko a lipoleiti hammoho ka ho tjheseletsa ka hare le ka ntle ho qoelisoa ka tlas'a metsi ho etsa seam spiral weld bakeng sa phala.
Mofuta ona oa phala ea tšepe o khetholloa ka ho ba le seam spiral weld, 'me katleho ea eona e phahameng ea tlhahiso e etsa hore e loketse ho etsa lipeipi tsa tšepe tse bophara bo boholo.
Botop Steel ke moetsi oa lipeipi tsa tšepe tse cheselitsoeng le mofani oa thepa ea tsoang Chaena, e fanang ka mefuta e mengata e fapaneng ea litekanyetso le boholo ba phala ea tšepe e ka etsoang ho latela litlhoko tsa morero oa hau.
Lihlahisoa tsa lipeipi tsa tšepe tsa SSAW tseo re ka fanang ka tsona li kenyelletsa pipe ea tšepe ea spiral API 5L, ASTM A252, EN 10217, GB/T 9711, le litekanyetso tse ling tse ngata.Ntle le moo, re fana ka lits'ebeletso tse ngata tse kenyelletsang ts'ebetso ea lipeipi tsa tšepe, ho penya, ho kenya liphaephe, ho roala, ho penta, le tse ling.
Molemo o ikhethang oa li-tubes tsa SSAW ke bokhoni ba ho hlahisa li-tubes tse bophara bo boholo ho fihlela ho 3,500 mm, tse ke keng tsa khoneha ka mefuta e meng ea li-tubes.
Ho phaella ho sena, li-tubes tsa SSAW li na le melemo ea lebelo la tlhahiso e potlakileng, bokhoni ba ho hlahisa li-tubes ka bolelele bo bolelele ba motho ka mong, le mefuta e mengata ea likopo.
Ho hlahisoa ha pipe ea tšepe ea SSAW ke mokhoa o itekanetseng haholo, o sa ntlafatseng haholo ts'ebetso ea tlhahiso ea liphaephe tsa tšepe, empa hape o tiisa boleng ba boleng bo phahameng ba sehlahisoa.
