Exporter China Steel Welded Carbon Pipe
ExportPipe ea tšepe ea carbon,Pipe ea tšepe ea China,Pipe ea tšepe e tlase ea Carbon,lipeipi tse cheselitsoeng, ho tsoa Chaena. Khamphani ea rona e sebetsa ka ho khetheha ho romelloeng kantle ho naha ea liphaephe tsa tšepe tse cheselitsoeng le lipeipi tsa tšepe tse se nang moeli. Selemo le selemo ho romelloa lithane tse likete tsa lipeipi tsa tšepe tse cheselitsoeng linaheng tse ling. Lipeipi tse cheselitsoeng tse atisang ho romeloa linaheng tse ling li arotsoe ka LSAW le SSAW. Na ua tseba phapang lipakeng tsa Pipe ea LSAW le Pipe ea SSAW?
LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), eo hape e bitsoang phala ea SAWL. E nka poleiti ea tšepe e le thepa e tala, e e bōpe ka mochini o bopang, ebe o etsa welding ea arc e nang le mahlakore a mabeli. Ka ts'ebetso ena phala ea tšepe ea LSAW e tla fumana ductility e ntle haholo, ho tiea ha weld, ho ts'oana, polasetiki le tiiso e kholo.
Letoto la bophara ba liphaephe tsa LSAW le leholo ho feta ERW, hangata ho tloha ho 16 inch ho isa ho 60 inch, 406mm ho isa 1500mm. Lits'ebetso tse ntle ho hanyetsa khatello e phahameng, le ho hanyetsa kutu ea mocheso o tlase.
E sebelisitsoe haholo liphaepheng tsa oli le khase, ka ho khetheha e hlokehang bophara bo boholo le phala e teteaneng ea lerako e nang le matla a phahameng le sebaka se selelele. Ho sa le joalo ka kaho ea mohaho o hlokang matla a thata, phekolo ea metsi, indasteri ea mocheso, mohaho oa borokho, joalo-joalo Ho ea ka litlhaloso tsa API, phala ea LSAW (phala ea SAWL kapa phala ea JCOE) e khethiloe ka ho khetheha ka lipalangoang tse kholo tsa oli le khase, maemong a liphaephe ho pholletsa le toropo, leoatle, le sebaka sa toropo. Tsena ke libaka tsa sehlopha sa 1 le sehlopha sa 2.
SSAW Pipe (Spiral Submerged Arc-Welding Pipe), eo hape e bitsoang HSAW pipe (Helical SAW), welding line shape joaloka helix. E sebelisa theknoloji e ts'oanang ea welding ea Submerged Arc-Welding e nang le pipe ea LSAW. Ka tsela e fapaneng SSAW phala ke spiral welded moo LSAW e longitudinally welded. Manufacturing process is rolling steel strip, ho etsa rolling direction na angle le tataiso ea setsi sa phala, ho etsa le ho tjheseletsa, kahoo seam tjheseletsa ke moleng spiral.
Sebaka sa bophara ba pipe ea SSAW se tloha ho 20 inch ho ea ho 100 inch, 406 mm ho 2540 mm. Karolo e molemo ke hore re ka fumana bophara bo fapaneng ba liphaephe tsa SSAW tse nang le boholo bo lekanang ba lesela la tšepe, ho na le kopo e pharaletseng bakeng sa thepa e tala. tšepe hlobolisa, 'me tjheseletsa seam lokela ho qoba khatello ea kelello ka sehloohong, litšoantšiso tse ntle ho jara khatello ea kelello.
The go tlhoka mesola ke dimension mpe 'meleng, tjheseletsa seam bolelele ke e telele ho feta phala bolelele, ho le bonolo ho etsa hore mefokolo ea mapetsong, lesoba moea, cinder kenyelletsoa, leeme tjheseletsa, tjheseletsa matla a ho hula boemo.
Bakeng sa lits'ebetso tsa lipeipi tsa oli le khase, empa ka litlhaloso tsa moralo oa peterole, pipe ea SSAW / HSAW e ka sebelisoa feela sehlopheng sa 3 le libaka tsa sehlopha sa 4. Sebopeho sa kaho, lipalangoang tsa metsi le phekolo ea likhoerekhoere, indasteri ea mocheso, mehaho joalo-joalo.
