Li-valve tse 5 tse atileng haholo liphaepheng tsa lik'hemik'hale li sebetsa joang? Sepheo se seholo? Liphaephe tsa lik'hemik'hale le li-valve tsa ho kenya ke life? (mefuta e 11 ea liphaephe + mefuta e 4 ea lisebelisoa tsa liphaephe + li-valve tse 11 tse kholo) Liphaephe tsa lik'hemik'hale, lintho tsena kaofela li ipabola sehloohong se le seng!

Liphaephe tsa lik'hemik'hale le li-valve tsa ho kenya

Mefuta ea liphaephe tsa lik'hemik'hale e arotsoe ka thepa: liphaephe tsa tšepe le liphaephe tse se nang tšepe.

Metal tube

Liphaephe tsa tšepe tse entsoeng ka tšepe, lipeipi tsa tšepe tse moroho, lipeipi tsa tšepe tse se nang moroko, lipeipi tsa koporo, lipeipi tsa aluminium, le lipeipi tsa loto.

① Peipi ea tšepe e lahliloeng:

Pipe ea tšepe ea cast ke e 'ngoe ea lipeipi tse sebelisoang hangata liphaepheng tsa lik'hemik'hale.

Ka lebaka la brittleness ea eona le bothata bo bobe ba ho hokahanya, e loketse feela ho fetisa mecha ea litaba e tlaase, 'me ha e tšoanelehe bakeng sa ho fetisa mocheso o phahameng le oa khatello e matla le lintho tse chefo le tse phatlohang. Hangata e sebelisoa liphaepheng tsa phepelo ea metsi ka tlas'a lefatše, liphaephe tsa khase le liphaephe tsa likhoerekhoere. Litlhaloso tsa liphaephe tsa tšepe tse entsoeng ka tšepe li hlahisoa ke Ф bophara ba ka hare × botenya ba lerako (mm).

②Peipi ea tšepe e koetsoeng:

Liphaephe tsa tšepe tsa seam li arotsoe ka liphaephe tse tloaelehileng tsa khase ea metsi (khatello ea ho hanyetsa 0.1 ~ 1.0MPa) le liphaephe tse teteaneng (khatello ea khatello ea 1.0 ~ 0.5MPa) ho latela khatello ea bona ea ho sebetsa.

Hangata e sebelisoa ho tsamaisa maro a khatello a kang metsi, khase, mouoane o futhumatsang, moea o hatelitsoeng le oli. Liphaephe tse entsoeng ka masenke li bitsoa lipeipi tsa masenke kapa lipeipi tse entsoeng ka masenke. Tse se nang masenke li bitsoa lipeipi tse ntšo tsa tšepe. Litlhaloso tsa eona li hlahisoa ho latela bophara ba lebitso. Bophahamo bo fokolang ka lebitso ke 6mm mme boholo ba bophara ba lebitso ke 150mm.

③ Peipi ea tšepe e sa tsitsang:

Molemo oa phala ea tšepe e se nang moeli ke boleng ba eona bo ts'oanang le matla a phahameng.

Thepa ke tšepe ea carbon, tšepe ea boleng bo holimo, tšepe e sa tsitsang, tšepe e sa jeleng paate le tšepe e sa cheseheng mocheso. Ka lebaka la mekhoa e fapaneng ea tlhahiso, ho na le mefuta e 'meli: liphaephe tsa tšepe tse chesang tse kentsoeng ka mocheso le lipeipi tsa tšepe tse sa tsitsang tse huloang ke serame. Boenjiniere ba liphaephe, liphaephe tse chesang tse chesang li sebelisoa hangata ha bophara bo feta 57mm, 'me liphaephe tse huloang ke serame li atisa ho sebelisoa ha bophara bo le ka tlase ho 57mm.

Lipeipi tsa tšepe tse se nang moroallo hangata li sebelisoa ho tsamaisa mefuta eohle ea likhase tse hatelitsoeng, mouoane le maro, 'me li khona ho mamella mocheso o phahameng (hoo e ka bang 435°C). Liphaephe tsa tšepe tsa alloy li sebelisoa ho tsamaisa mecha ea litaba e senyang, eo har'a eona liphaephe tsa alloy tse sa keneleng mocheso li ka mamellang mocheso ho fihlela ho 900-950 ℃. Tlhaloso ea phala ea tšepe e sa tsitsang e hlahisoa ke Ф bophara ba ka hare × botenya ba lerako (mm).

Bophara bo boholo ba kantle ba phala e huloang ke serame ke 200mm, 'me bophara bo boholo ba kantle ba phala e kolobisitsoeng e chesang ke 630mm. Liphaephe tsa tšepe tse se nang moroko li arotsoe ka liphaephe tse akaretsang tse se nang moroallo le lipeipi tse khethehileng tse se nang moroallo ho ea ka tšebeliso ea tsona, tse kang lipeipi tse petsohang tsa petroleum tse se nang moroko, lipeipi tsa boiler tse se nang moroko, le lipeipi tsa manyolo tse se nang moroko.

④ Peipi ea koporo:

Tube ea koporo e na le phello e ntle ea ho fetisa mocheso.

Haholo-holo e sebelisoa liphaepheng tsa lisebelisoa tsa phapanyetsano ea mocheso le lisebelisoa tsa cryogenic, li-tubes tse lekanyang khatello ea lisebelisoa kapa ho tsamaisa maro a hatelitsoeng, empa ha mocheso o feta 250 ℃, ha oa lokela ho sebelisoa tlas'a khatello. Hobane theko e theko e boima haholo, hangata e sebelisoa libakeng tsa bohlokoa.

⑤Tube ea aluminium:

Aluminium e na le khanyetso e ntle ea kutu.

Li-tubes tsa aluminium li atisa ho sebelisoa ho tsamaisa mecha ea litaba e kang concentrated sulfuric acid, acetic acid, hydrogen sulfide le carbon dioxide, 'me e boetse e sebelisoa hangata ho fapanyetsana mocheso. Li-tubes tsa aluminium ha li hanyetsane le alkaline 'me li ke ke tsa sebelisoa ho tsamaisa metsoako ea alkaline le litharollo tse nang le li-ion tsa chloride.

Ha matla a mochine oa tube ea aluminium a fokotseha haholo ka ho eketseha ha mocheso, mocheso oa tšebeliso ea tube ea aluminium o ke ke oa feta 200 ° C, 'me mocheso oa tšebeliso o tla fokotseha bakeng sa pipeline e hatelitsoeng. Aluminium e na le thepa e ntle ea mochini mochesong o tlase, kahoo li-tubes tsa aluminium le aluminium alloy li sebelisoa haholo lisebelisoa tsa karohano ea moea.

⑥ Peipi e etellang pele:

Hangata lipeipi tsa loto li sebelisoa e le liphaephe bakeng sa ho tsamaisa mecha ea litaba e nang le asiti. Li ka tsamaisa 0.5% -15% sulfuric acid, carbon dioxide, 60% hydrofluoric acid, le acetic acid e nang le mahloriso a ka tlaase ho 80%. Ha e loketse ho tsamaisa nitric acid, hypochlorous acid le mecha e meng ea litaba. Mocheso o phahameng oa ho sebetsa oa pipe ea lead ke 200 ℃.

Tube e se nang tšepe

Pipe ea polasetiki, phala ea polasetiki, phala ea khalase, phala ea ceramic, phala ea samente.

①Pipe ea polasetiki:

Melemo ea liphaephe tsa polasetiki ke ho hanyetsa kutu e ntle, boima bo bobebe, ho bōptjoa ha bonolo le ho sebetsa habonolo.

Bothata ke matla a tlaase le ho hanyetsa mocheso o futsanehileng.

Hajoale, liphaephe tsa polasetiki tse sebelisoang haholo ke liphaephe tse thata tsa polyvinyl chloride, lipeipi tse bonolo tsa polyvinyl chloride, lipeipi tsa polyethylene,liphaephe tsa polypropylene, le lipeipi tsa tšepe tse nang le polyolefin le polychlorotrifluoroethylene tse fafalitsoeng holim'a metsi.

②Tube ea rabara:

Thepa ea rabara e na le khanyetso e ntle ea kutu, boima bo bobebe, polasetiki e ntle, ho kenya habonolo le ho qhaqha habonolo.

Li-tubes tsa rabara tse sebelisoang ka tloaelo hangata li entsoe ka rabara ea tlhaho kapa rabara ea maiketsetso, 'me li loketse linako tseo litlhoko tsa khatello li seng holimo.

③Tube ea khalase:

Tube ea khalase e na le melemo ea ho hanyetsa kutu, ho pepeseha, ho hloekisa habonolo, ho hanyetsa ho tlaase, le theko e tlaase. Bothata ke hore e brittle ebile ha e khone ho mamella khatello.

Hangata e sebelisoa litekong kapa maemong a mosebetsi oa liteko.

④Tube ea Ceramic:

Li-ceramics tsa lik'hemik'hale li tšoana le khalase 'me li na le khanyetso e ntle ea kutu. Ho phaella ho hydrofluoric acid, fluorosilicic acid le alkalis e matla, li ka mamella mefuta e sa tšoaneng ea li-inorganic acid, organic acid le metsoako ea tlhaho.

Ka lebaka la matla a eona a tlase le brittleness, hangata e sebelisoa ho tlosa mecha ea litaba e senyang ka har'a likhoerekhoere le liphaephe tsa moea.

⑤Peipi ea samente:

E sebelisoa haholo-holo linakong tseo litlhoko tsa khatello le ho tiisoa ha pipe ea ho kopanya li seng holimo, joalo ka liphaephe tsa likhoerekhoere tse ka tlas'a lefatše le liphaephe tsa drainage.
