Phaephe ea tšepe ea ERW
Phaephe ea ERW (phaephe e welded e hanyetsang motlakase) le phaephe ea CDW (phaephe e welded e batang) ke mekhoa e 'meli e fapaneng ea tlhahiso bakeng sa liphaephe tsa tšepe tse welded.
1. Ts'ebetso ea tlhahiso
| Lintho tsa papiso | Phaephe ea ERW (phaephe e svetselitsoeng ea khanyetso ea motlakase) | Phaephe ea CDW (phaephe e phuthetsoeng ka welded e batang) |
| Mabitso a felletseng | Motlakase Khanyetso Welded Pipe | Pipe e Huloang e Batang e Welded |
| Mokhoa oa ho theha | Bokaholimo ba poleiti ea tšepe bo futhumatsoa ke motlakase o phahameng oa maqhubu 'me bo hatelloa ebe bo kopanngoa hore bo be sebopeho. | Pele e tjheselletsoa ka har'a liphaephe, ebe e huloa ka serame (kalafo ea ho fetoha ha serame) |
| Mokhoa oa ho tjheseletsa | Ho Welding ea Khahlano le Maqhubu a Phahameng (HFW/ERW) | Hangata ho tjheseletsa ka arc ea ERW kapa ea argon (TIG) ho sebelisoa bakeng sa ho tjheseletsa. |
| Ts'ebetso e latelang | Ho lekanya le ho seha ka ho toba ka mor'a ho tjheseletsa | Ho thala ka mokhoa o batang (ho phutholla ka mokhoa o batang) ho qeta kamora ho tjheseletsa |
2. Litšobotsi tsa ts'ebetso
Phaephe ea ERW
Ho nepahala ha tekanyo: Kakaretso (± 0.5% ~ 1% mamello ea bophara ba kantle)
Boleng ba bokaholimo: Ho tjheseletsa ho bonahala hanyane mme ho hloka ho bentshwa
Litšobotsi tsa mechine: Matla a itšetlehile ka thepa ea motsoali, 'me ho ka ba le ho nolofala sebakeng sa ho tjheseletsa.
Khatello ea masala: E tlase (phekolo e bonolo feela ea mocheso kamora ho tjheseletsa)
Phaephe ea CDW
Ho nepahala ha litekanyo: ho phahame haholo (ka hare ho ± 0.1mm, ho loketse merero ea ho nepahala)
Boleng ba bokaholimo: bokaholimo bo boreleli, ha ho na sekala sa oxide (se bentšitsoeng ka mor'a ho taka ka serame)
Thepa ea mechini: ho thatafatsa ho sebetsa ka serame, matla a eketsehile ka 20% ~ 30%
Khatello ea mali e setseng: e phahameng (ho hlokahala ho kenya metsi ho felisa khatello ea ho hula ka serame)
3. Maemo a tshebediso
ERW: liphaephe tsa oli/khase, liphaephe tsa meaho (scaffolding), liphaephe tsa mokelikeli o nang le khatello e tlase (GB/T 3091)
CDW: disilindara tsa hydraulic, dikarolo tsa mechine tse nepahetseng (tse kang matsoho a bearing), di-shaft tsa phetiso ya koloi (dibaka tse nang le ditlhoko tse phahameng tsa ho nepahala)
Maemo a tloaelehileng a mefuta
ERW: API 5L (phaephe ea liphaephe), ASTM A53 (phaephe ea sebopeho), EN 10219 (phaephe e welletsoeng e tloaelehileng ea Europe)
CDW: ASTM A519 (phaephe e huloang ka mokhoa o nepahetseng o batang), DIN 2391 (phaephe e tloaelehileng ea Jeremane e nang le mokhoa o phahameng oa ho sebetsa)
Phaephe ea CDW = Phaephe ea ERW + ho hula ho batang, ka litekanyo tse nepahetseng haholoanyane le matla a phahameng, empa hape le litšenyehelo tse phahameng.
Phaephe ea ERW e loketse merero ea kaho ka kakaretso, ha phaephe ea CDW e sebelisoa lefapheng la mechini e nang le nepahalo e phahameng.
Haeba tshebetso ya phaephe ya CDW e hloka ho ntlafatswa haholoanyane, kalafo ya ho tjhesa e ka eketswa (ho fedisa kgatello ya ho sebetsa e batang).
