ASTM A234 Longitudinal Weld Pipe
Tsebisa:
Lefatšeng la liphaephe tsa tšepe, mantsoe a tloaelehileng a hlaha khafetsa: pipe e entsoeng ka longitudinally welded.Liphaephe tsena li phetha karolo ea bohlokoa liindastering tse fapaneng 'me li sebeletsa merero e fapaneng.
Longitudinal welded pipe, eo hape e tsejoang e le phala e otlolohileng ea seam welded, ke phala ea tšepe e entsoeng ka poleiti ea tšepe e chesang kapa e batang kapa ea tšepe.Lebitso la bona le tsoa ts'ebetsong ea welding, e hlahang ka mola o otlolohileng ka bolelele ba phala.Mokhoa ona o tiisa boleng bo tsitsitseng ba weld le manonyeletso a tiileng, ho thibela ho lutla le ho matlafatsa bots'epehi ba sebopeho ka kakaretso.

Pipe e cheselitsoeng ka longitudinal:
Ka hlakoreng le leng,lipeipi tse otlolohileng tse cheselitsoengli etsoa ho sebelisoa mekhoa e fapaneng ea ho tjheseletsa joalo ka arc welding kapa resistance welding.Hangata liphaephe tsena li entsoe ka likheo tsa li-tube tse se nang moroallo kapa tse cheselitsoeng, ebe li etsoa sebopeho se lakatsehang.Longitudinal Welded Pipe e fana ka matla a ikhethang le ho tšoarella, e etsa hore e be e loketseng bakeng sa lits'ebetso tsa indasteri tse kenyelletsang maemo a khatello e phahameng kapa meroalo e boima.
Liphaephe tse cheselitsoeng ka longitudinal li kena ts'ebetsong e nepahetseng ea welding ho etsa bonnete ba hore botenya ba lebota bo lekanang ho pholletsa le phala e nang le mefokolo e fokolang.Sena se ba etsa khetho e ntle bakeng sa lits'ebetso tsa meralo joalo ka kaho, scaffolding le liqubu.
Ka lehlakoreng le leng, liphaephe tse otlolohileng tse cheselitsoeng li na le libopeho le boholo bo fapaneng.Ts'ebetso ea bona ea tlhahiso e lumella ho itlhophisa, ho etsa hore li tšoanelehe bakeng sa lits'ebetso tse hlokang litekanyo tse itseng kapa meralo e rarahaneng.Ho feta moo, liphaephe tse cheselitsoeng ka longitudinally li sebelisoa haholo liindastering tse kang oli le khase, likoloi, le sefofane ka lebaka la matla a tsona a phahameng le ho hanyetsa khatello ea kelello.
