Pipe ea tšepe e cheselitsoeng
Litlhaloso tsa lipeipi tsa tšepe tse cheselitsoeng hangata li hlahisoa ho ea ka bophara ba kantle le botenya ba lebota, 'me hoa hlokahala ho etsa bonnete ba hore tlhahlobo ea hydrostatic, matla a thata a thepa ea weld le a batang a kobang a latela melaoana.
Liphaephe tse cheselitsoeng ka spiral li ka hlahisoa ka bophara bo boholo ho tloha ho likhoele tse moqotetsane 'me ka kakaretso li matla ho feta liphaephe tse otlolohileng tsa seam, e leng se etsang hore li tšoanelehe ho sebelisoa lits'ebetsong tse kholo tsa liphaephe. Ts'ebetso ea tlhahiso ea mofuta ona oa phala e cheselitsoeng e na le lipoleiti tsa tšepe tsa welding kapa likhoele ka mor'a hore li phuthoe le ho bōptjoa, 'me seam sa weld se ka ba se otlolohileng kapa sa spiral, ho itšetlehile ka mokhoa oa tlhahiso.
E ka fetoha
Katleho ea litšenyehelo
Matla a phahameng
Bokgoni bo phahameng
Spiral welded pipes e khona ho hlahisa liphaephe tse kholo tsa bophara li sebelisa tšepe e fokolang, e sebetsang haholo ho hlahisa liphaephe tse kholo tse sebelisang lisebelisoa tse fokolang tse tala.
Ha ho bapisoa le bolelele bo lekanang ba phala e otlolohileng ea seam welded, bolelele ba weld ba phala ea tšepe e chitja bo eketseha ka 30-100%. Le hoja lebelo la tlhahiso le le tlaase, boholo ba liphaephe tse cheselitsoeng ka bophara bo boholo li cheselitsoe ka spiral, e leng ho fokotsang litšenyehelo ho isa bohōleng bo itseng le ho ntlafatsa katleho ea litšenyehelo.
Matla a threaded tjheseletsa phala ka kakaretso e phahame ho feta ea seam otlolohileng welded phala, 'me e ka hlahisa phala welded le bophara e khōloanyane ho tloha billet moqotetsane,' me ka hare le ka ntle welded spiral tjheseletsa seam eketsa steeliness, e leng se etsang hore phala robust ho feta.
Ts'ebetso ea tlhahiso ea pipi e cheselitsoeng ka spiral haholo-holo e kenyelletsa mehato e latelang:
Tokisetso ea lisebelisoa tse tala: li-coil tse hlobolang li sebelisoa e le lisebelisoa tse ka sehloohong tse tala, 'me terata ea welding le flux lia hlokahala. Lisebelisoa tsena tse tala li tlas'a liteko tse matla tsa 'mele le lik'hemik'hale pele li sebelisoa.
Kalafo ea li-strip: Meqathatso ea batalatsoa, ea pongoa le ho beoloa pele e etsoa, hammoho le ho hloekisoa bokaholimo le ho kobeha mathokong ho netefatsa boleng le ho ba sephara ha sekhahla.
Ho theha: Li-strips li etsoa ka sebopeho se hlokahalang sa billet ka ho etsa roll e laoloang ka ntle kapa ka hare.
Welding: terata e le 'ngoe kapa terata e habeli e kenelletseng ka tlas'a metsi theknoloji ea arc e sebelisoa ho cheselletsa billet.
Tlhahlobo ea Boleng: Netefatsa tlhahlobo ea 100% e sa senyeheng ea li-spiral welds. Haeba ho na le bofokoli, sistimi e tla lla ka bo eona le ho tšoaea ho fafatsa, basebetsi ba tlhahiso ba tla fetola mekhahlelo ea ts'ebetso ho latela tlhaiso-leseling ena ho felisa liphoso ka nako.
Ho khaola le ho hlahloba ka lekhetlo la pele: Pipe ea tšepe ea carbon e khaola likotoana tse le 'ngoe ho sebelisoa mochine oa ho itšeha plasma ea moea 'me ho etsoa tsamaiso e tiileng ea pele ea tlhahlobo. Tlhahlobo ea pele e kenyelletsa ho lekola thepa ea mochini oa weld, sebopeho sa lik'hemik'hale, boemo ba fusion, boleng ba bokaholimo ba phala ea tšepe le tlhahlobo e sa senyeheng. Ke feela ka mor'a ho netefatsa hore mokhoa oa ho etsa liphaephe o tšoaneleha, o ka kenngoa ka molao tlhahiso.
Tsoelo-pele: Tlhahlobo ea Manual ultrasonic le X-ray ea weld moo ho nang le ts'ebetso e tsoelang pele ea ho lemoha liphoso tsa acoustic holim'a weld. Haeba ho ne ho fumanoa liphoso, NDT e ile ea boela ea etsoa ka ho lokisoa ho fihlela ho netefatsoa hore liphoso li felisitsoe.
Pipe end machining: The rpeipi e kolobisitsoenglipheletsong li entsoe ka mochini ho etsa bonnete ba hore pheletso ea perpendicularity, angle ea bevel le mephetho e boreleli li laoloa ka nepo.

Lisebelisoa tse khethehileng li kenyelletsa: mesebetsi ea metsi: bakeng sa phepelo ea metsi, drainage le lipalangoang tse ling tsa metsi. Indasteri ea Petrochemical: e sebelisetsoang ho tsamaisa mecha ea litaba e fapaneng ea lik'hemik'hale. Indasteri ea lik'hemik'hale: joalo ka liphaephe tsa mochini o futhumatsang mocheso, tora le tanka. Indasteri ea matla a motlakase: e sebelisetsoang mouoane oa mouoane o nang le khatello e phahameng, pipe ea lebota e pholileng ka metsi joalo-joalo.
