Phaephe ea X42 SSAW Spiral Welded Tube
Hlahisa:
Lefapheng la liphaephe tsa tšepe, mekhoa e fapaneng ea ho tjheseletsa e sebelisoa ho fihlela likhokahano tsa boleng bo holimo le tse tšepahalang. Mokhoa o mong o joalo keho tjheseletsa arc e qoelitsoeng ka hare ho spiral(SAW), e bapalang karolo ea bohlokoa tlhahisong ea phaephe ea X42 SSAW. Jwalo ka moetapele oa indasteri, Cangzhou Spiral Steel Pipe Group Co., Ltd., e tsebahalang ka lets'oao la eona la Wuzhou, e latela maemo a machaba mme e netefatsa hore lihlahisoa tsa eona (ho kenyeletsoa phaephe e welletsoeng ka arc e spiral e nang le X42) li fihlela API Spec 5L, ASTM A139, ASTM A252 le EN 10219. Blogeng ena re kenella lefats'eng le khahlang la phaephe ea X42 SSAW, re totobatsa melemo ea ho sebelisa welding ea arc e spiral e spiral tlhahisong ea phaephe e welletsoeng ka spiral.
Ithute ka ho Welding ka Arc e Keneng ka Spiral (SAW):
Ho welding ka arc e kenelletseng ka hare ho spiral, e tsejoang hape e le SAW, ke mokhoa o ikhethileng oa ho welding o sebelisoang ho etsa liphaephe tse welletsoeng ka hare ho spiral tse kangPhaephe ea X42 SSAWMokhoa ona o kenyelletsa ho qhibilihisa phallo ea terata le tšepe ea motheo ho sebelisoa mocheso o hlahisoang ke ho cha ha arc pakeng tsa terata le phallo e ka tlas'a lera la phallo. Lera la phallo le sebetsa e le thibelo e sireletsang, e thibelang litšila tsa sepakapaka ho kena-kenana le ts'ebetso ea ho kopanya. Mokhoa ona o na le melemo e 'maloa ho feta mekhoa e meng ea ho tjheseletsa.

Melemo ea ho tjheseletsa arc e qoelitsoeng ka spiral:
1. Li-weld tse tsitsitseng le tsa boleng bo holimo: Mokhoa oa SAW o sebelisoang phaepheng ea X42 SSAW o hlahisa li-weld tse tšoanang le tsa boleng bo holimo. Ha arc e qoelisoa ka har'a phallo, e theha tikoloho e laoloang e sireletsang sebaka sa ho kopanya ho tsoa linthong tse kantle, e netefatsang manonyeletso a tsitsitseng le a tšepahalang. Sena se fella ka tlhahiso ea liphaephe tse phuthetsoeng ka spiral tse nang le matla a ikhethang le ho tšoarella.
2. Bokgoni bo eketsehileng: Ho tjheseletsa arc e kenelletseng ka hare ho spiral ho fana ka bokgoni bo boholo ka lebaka la tlhaho ya yona e iketsahallang. Tshebetso ena e kenyelletsa ho fepa terata ya ho tjheseletsa ka boiketsetso ka ho tswelang pele, e leng se fellang ka tlhahiso e potlakileng ha ho ntse ho bolokwa ho nepahala. Sekgahla se phahameng sa ho kenya le ho itshetleha hanyane mosebetsing wa matsoho ho tlatsetsa bokgoning le katlehong ya ditjeo.
3. E loketse lits'ebetso tse fapaneng: Phaephe ea X42 SSAW e entsoeng ka ho welding ka arc e spiral e sebelisoa haholo liindastering tse ngata. Liphaephe tsena li sebelisoa lipalangoang tsa oli le khase, liphaephe tsa metsi, tšehetso ea meaho ea kaho, metheo ea liqubu, le tse ling. Ho tenyetseha le ho tšepahala ha phaephe ea X42 SSAW ho etsa hore e be ntle bakeng sa lits'ebetso tsa bohlokoa.
4. Litšobotsi tse ntlafalitsoeng tsa mechini: Mokhoa oa SAW o netefatsa taolo e betere ea liparamente tsa ho tjheseletsa nakong ea tlhahiso ea liphaephe tse tjheselitsoeng tsa arc tse koahetsoeng ka spiral X42. Taolo ena e ka ntlafatsa litšobotsi tsa mechini, ho kenyeletsoa ho tiea ha tšusumetso, matla a tlhahiso le matla a ho thaepa. Ka lebaka leo, liphaephe tsena li na le khanyetso e ntle khahlanong le matla a kantle 'me li loketse esita le libakeng tse thata.
Ha re phethela:
Ha re hlahloba lefats'e la ho tjheseletsa arc e kenelletseng ka hare ho spiral tlhahisong ea liphaephe tsa X42 SSAW, hoa hlaka hore na ke hobane'ng ha mokhoa ona o sebelisoa haholo indastering ea tšepe. Ho tjheseletsa arc e kenelletseng ka hare ho spiral ho fana ka melemo e mengata joalo ka li-weld seams tse tsitsitseng, katleho e eketsehileng, ho tenyetseha le thepa e ntlafetseng ea mechini, ho netefatsa hore liphaephe tse kenelletseng ka hare ho spiral, joalo ka liphaephe tsa tšepe tsa X42 SSAW tse hlahisoang ke Cangzhou Spiral Steel Pipe Group Co., Ltd., li fihlela maemo a boleng bo holimo. Ka hona, mabapi le ts'epo, ho tšoarella le ts'ebetso, tube ea X42 SSAW e ipaka e le khetho e ntle bakeng sa mefuta e mengata ea lits'ebetso tsa indasteri.
