Pipe ea tšepe ea Spiral ke ea boleng bo holimo le theko e tlase
Pipe ea tšepe ea Spiral ke phala ea tšepe ea spiral seam e entsoeng ka tšepe e hlobolisang e le thepa e tala, hangata e bopiloeng ke extrusion e futhumetseng mme e kenngoe ka mokhoa oa othomathike oa terata e habeli ka mahlakoreng a mabeli. Pipe ea tšepe ea spiral e romela tšepe e hlobolisa ho yuniti ea phala e cheselitsoeng. Kamora ho pitikisoa ke lirolara tse ngata, tšepe e hlobolisa e phuthoa butle-butle ho etsa phala e chitja e se nang letho e nang le lekhalo le bulehileng. Fetola phokotso ea rolara ea extrusion ho laola lekhalo la weld ho 1 ~ 3mm le ho etsa hore lipheletsong tse peli tsa mateano a marang-rang a phahamise.
(1) Lisebelisoa tse tala, ke hore, khoele ea tšepe ea hlobolisa, terata ea welding le flux. Tlhahlobo e matla ea 'mele le ea lik'hemik'hale e tla etsoa pele ho kenyelletsoa.
(2) The butt joint of strip steel head and mohatla e nka terata e le 'ngoe kapa terata e habeli e kenelletseng ka tlas'a metsi arc welding,' me welding e kenelletseng ka tlas'a metsi e amoheloa bakeng sa ho lokisa welding ka mor'a ho pitika ka phala ea tšepe.

Haeba ho na le mefokolo, e tla lla le ho fafatsa matšoao ka bo eona, 'me basebetsi ba tlhahiso ba tla fetola mekhoa ea ts'ebetso ka nako efe kapa efe ho felisa liphoso ka nako.
(9) Pipe ea tšepe e khaola likotoana tse le 'ngoe ka mochine oa ho itšeha plasma ea moea.
(10) Ka mor'a ho khaola ka phala e le 'ngoe ea tšepe, sehlopha se seng le se seng sa phala ea tšepe se tla ba tlas'a tsamaiso e tiileng ea pele ea tlhahlobo ho hlahloba thepa ea mochine, sebopeho sa lik'hemik'hale, boemo ba fusion, boleng ba holim'a phala ea tšepe le NDT ho etsa bonnete ba hore phala e etsoa. ts'ebetso e tšoaneleha pele e ka kenngoa ka molao tlhahisong.
(11) Likarolo tse nang le matšoao a tsoelang pele a ho lemoha liphoso tsa acoustic holim'a weld li tla hlahlojoa hape ka manual ultrasonic le X-ray. Haeba ho na le bofokoli, ka mor'a ho lokisoa, ba tla boela ba be tlas'a NDT ho fihlela ho netefatsoa hore mefokolo e felisitsoe.

(13) Pipe e 'ngoe le e' ngoe ea tšepe e tlas'a teko ea hydrostatic, 'me khatello e amohela tiiso ea radial. Khatello ea teko le nako li laoloa ka thata ke mochine oa ho lemoha microcomputer oa khatello ea metsi phala ea tšepe. Litekanyetso tsa liteko li hatisoa le ho rekotoa ka bo eona.
(14) Qetello ea phala e entsoe ka mokhoa o nepahetseng ho laola perpendicularity, angle ea letsoapo le bohale bo bobebe ba sefahleho sa ho qetela.
1. Haeba lekhalo le le leholo haholo, phello e haufi e tla fokotseha, mocheso oa hona joale oa eddy o tla be o sa lekana, 'me motsoako oa weld intergranular o tla fokola, o fella ka fusion e sa fellang kapa ho phunyeha.

Ka mor'a hore likarolo tse peli tsa tube e se nang letho e futhumale ho mocheso oa ho tjheseletsa, lithollo tse tloaelehileng tsa tšepe li thehoa tlas'a extrusion ea extrusion rolara, e phunyeletsang le crystallize e mong le e mong, 'me qetellong e theha weld e tiileng. Haeba matla a extrusion ea pipe ea tšepe ea spiral e nyenyane haholo, palo ea likristale tse tloaelehileng e tla ba nyenyane, matla a tšepe ea weld a tla fokotseha, 'me ho phunyeha ho tla etsahala ka mor'a khatello ea kelello; Haeba matla a extrusion a le maholo haholo, tšepe e qhibilihisitsoeng e tla ntšoa ka ntle ho weld, e ke keng ea fokotsa matla a weld feela, empa hape e hlahisa palo e kholo ea li-burrs tse ka hare le tsa ka ntle, esita le ho baka liphoso tse kang ho kopana ha tjheseletsa.
