Hangata di sebediswa ho tsamaisa metsi, kgase, mouoane o futhumatsang, moya o hatelletsoeng, oli le maro a mang a kgatello. Galvanized e bitswa phala ya tshepe e tshweu kapa phala ya galvanized. Tse sa galvanized di bitswa diphaephe tsa tshepe e ntsho. Ditlhaloso tsa yona di hlaloswa ka bophara ba nominee. Bonyane bophara ba nominee ba 6mm, bophara ba nominee ba nominee ba 150mm.
③ Phaephe ea tšepe e se nang seamless:
Phaephe ea tšepe e se nang seamless e na le molemo oa boleng bo tšoanang le matla a phahameng.
Thepa ea eona e na le tšepe ea carbon, tšepe ea boleng bo holimo, tšepe e nang le motsoako o tlase, tšepe e sa ruseng, tšepe e sa futhumatseng. Ka lebaka la mekhoa e fapaneng ea tlhahiso, e arotsoe ka mefuta e 'meli ea phala ea tšepe e sa ruseng e phuthoang ka mocheso le phala ea tšepe e sa ruseng e batang. Bophara ba phala ea boenjiniere ba liphaephe bo fetang 57mm, phala e sebelisoang hangata e phuthoang ka mocheso, 57mm ka tlase ho phala e sebelisoang hangata e batang.
Phaephe ea tšepe e se nang seam e atisa ho sebelisoa ho tsamaisa mefuta e fapaneng ea likhase tse hatelletsoeng, mouoane le metsi, e ka mamella mocheso o phahameng (hoo e ka bang 435 ℃). Phaephe ea tšepe e kopantsoeng e sebelisetsoa ho tsamaisa mecha ea litaba e senyang, eo phaephe ea tšepe e sa keneleng mocheso e ka mamellang mocheso ho fihlela ho 900-950 ℃. Litlhaloso tsa phaephe ea tšepe e se nang seam ho ea ho bophara ba ka hare ba Ф × botenya ba lebota (mm).
Bophara bo boholo ba kantle ba phaephe e huloang ke serame ke 200mm, 'me bophara bo boholo ba kantle ba phaephe e phutholohileng e chesang ke 630mm. Phaephe ea tšepe e se nang sekoli e arotsoe ka phaephe e akaretsang e se nang sekoli le phaephe e khethehileng e se nang sekoli ho latela tšebeliso ea eona, joalo ka phaephe e se nang sekoli bakeng sa ho petsoha ha peterole, phaephe e se nang sekoli bakeng sa boiler, phaephe e se nang sekoli bakeng sa manyolo le tse ling.
④Phaephe ea koporo:
Phaephe ea koporo e na le phello e ntle ea phetisetso ea mocheso.
Haholo-holo e sebelisoa lisebelisoa tsa phapanyetsano ea mocheso le liphaephe tsa sesebelisoa sa ho pholisa ka botebo, tube ea ho lekanya khatello ea lisebelisoa kapa phetiso ea mokelikeli o hatelletsoeng, empa mocheso o phahame ho feta 250 ℃, ha oa lokela ho sebelisoa tlas'a khatello. Ka lebaka la theko e boima haholo, hangata e sebelisoa libakeng tsa bohlokoa.
⑤ Phaephe ea aluminium:
Aluminium e na le khanyetso e ntle ea ho bola.
Liphaephe tsa aluminium li atisa ho sebelisoa ho tsamaisa asiti e matla ea sulfuric, asiti ea acetic, hydrogen sulfide le carbon dioxide le mecha e meng ea litaba, 'me li boetse li sebelisoa hangata ho li-exchange tsa mocheso. Liphaephe tsa aluminium ha li hanele alkali 'me li ke ke tsa sebelisoa ho tsamaisa litharollo tsa alkaline le litharollo tse nang le li-ion tsa chloride.
Ka lebaka la matla a mechini a tube ea aluminium ka lebaka la ho phahama ha mocheso le phokotso e kholo ea ts'ebeliso ea lipeipi tsa aluminium, kahoo ts'ebeliso ea lipeipi tsa aluminium e ke ke ea feta 200 ℃, bakeng sa phaephe ea khatello, ts'ebeliso ea mocheso e tla ba tlase le ho feta. Aluminium e na le thepa e betere ea mechini mochesong o tlase, kahoo lipeipi tsa aluminium le alloy tsa aluminium li sebelisoa haholo lisebelisoa tsa karohano ea moea.
(6) Phaephe e nang le loto:
Phaephe ea loto e atisa ho sebelisoa e le phaephe ea ho tsamaisa asiti, e ka tsamaisoa ho tloha ho 0.5% ho isa ho 15% ea asiti ea sulfuric, carbon dioxide, 60% ea asiti ea hydrofluoric le acetic acid e ka tlase ho 80% ea seaplane, ha ea lokela ho isoa ho asiti ea nitric, asiti ea hypochlorous le seaplane se seng. Mocheso o phahameng ka ho fetisisa oa ts'ebetso oa phaephe ea loto ke 200℃.
Liphaephe tse seng tsa tšepe
Phaephe ea polasetiki, phaephe ea polasetiki, phaephe ea khalase, phaephe ea letsopa, phaephe ea samente.
①Phaephe ea polasetiki:
Melemo ea phaephe ea polasetiki ke ho hanyetsa mafome hantle, boima bo bobebe, ho bopa habonolo, le ho sebetsa habonolo.
Mathata ke matla a tlase le ho hanyetsa mocheso hantle.
Hona jwale diphaephe tsa polasetiki tse sebediswang haholo ke phaephe e thata ya polyvinyl chloride, phaephe e bonolo ya polyvinyl chloride, phaephe ya polyethylene, phaephe ya polypropylene, hammoho le polyethylene e fafatsang hodima phaephe ya tshepe, polytrifluoroethylene le tse ding.

Mefuta e 4 ea Lisebelisoa
Ntle le phaephe e ka hara phaephe, e le ho fihlela ditlhoko tsa tlhahiso ya tshebetso le ho kenya le ho hlokomela, ho na le dikarolo tse ding tse ngata ka hara phaephe, tse kang diphaephe tse kgutshwane, di-elbow, di-tee, di-reducer, di-flange, di-blind le tse ding.
Hangata re bitsa likarolo tsena bakeng sa lisebelisoa tsa liphaephe tse bitsoang li-fittings. Li-fittings tsa liphaephe ke likarolo tsa bohlokoa tsa phaephe. Mona ke selelekela se sekhutšoanyane sa li-fittings tse 'maloa tse sebelisoang hangata.
① Setsoe
Setsoe se sebediswa haholoholo ho fetola tataiso ya phaephe, ho ya ka tekanyo ya ho kobeha ha setsoe ya dihlopha tse fapaneng, setswe se tlwaelehileng sa 90 °, 45 °, 180 °, 360 °. Setswe sa 180 °, 360 °, se tsejwang hape e le kobeho e bōpehileng jwalo ka "U".
Hape ho na le litlhoko tsa ho etsa liphaephe tsa ts'ebetso tse nang le angle e itseng ea setsoe. Li-elbow li ka sebelisoa ho kobeha ha phaephe e otlolohileng kapa ho tjheseletsa phaephe 'me tsa fumaneha, li ka boela tsa sebelisoa ka mor'a ho bopa le ho tjheseletsa, kapa ho lahla le ho betla le mekhoa e meng, joalo ka ha ho etsoa ka phaephe e nang le khatello e phahameng, tšepe ea carbon kapa tšepe ea alloy e betla le ho betla.
②Tee
Ha liphaephe tse peli li hokahane kapa li hloka ho ba le bypass shunt, ho kenya sehokelong ho bitsoa tee.
Ho ya ka dikhutlo tse fapaneng tsa phihlello ya phaephe, ho na le phihlello e otlolohileng ho tee ya kgokelo e ntle, tee ya kgokelo e otlolohileng. Tee ya ho sekamela ho ya ka angle ya ho sekamela ho beha lebitso, jwalo ka tee ya ho sekamela ya 45 ° le tse ding.
Ho phaella moo, ho ya ka boholo ba caliber ya lesoba le sehokelo ka ho latellana, jwalo ka tee e lekanang ka bophara. Ntle le di-tee fittings tse tlwaelehileng, empa hape hangata ka palo ya di-interface tse bitswang, mohlala, tse nne, tse hlano, tee ya kgokelo e otlolohileng. Di-tee fittings tse tlwaelehileng, ho phaella ho welding ya phaephe, ho na le welding ya sehlopha e bopilweng, ho lahla le ho betla.
③Nipple le reducer
Ha kopano ea liphaephe e haella karolo e nyane, kapa ka lebaka la litlhoko tsa tlhokomelo ka har'a phaephe ho beha karolo e nyane ea phaephe e ka tlosoang, hangata ho sebelisoa Nipple.
Ho nkuwa ha nipple ka lihokelo (tse kang flange, screw, jj.), kapa e se e le tube e kgutshwane, e tsejwang hape e le gasket ya phaephe.
E tla ba bophara ba liphaephe tse peli tse sa lekanang tsa molomo tse hokahaneng le li-fitting tsa liphaephe tse bitsoang reducer. Hangata li bitsoa hlooho ea boholo. Li-fitting tse joalo li na le sesebelisoa sa ho fokotsa liphaephe, empa hape li na le sesebelisoa sa ho fokotsa liphaephe se khaotsoeng le se kopantsoeng kapa se kopantsoeng ka poleiti ea tšepe e phutholohileng. Li-reducer liphaepheng tse nang le khatello e phahameng li entsoe ka ho phunya kapa ho nyenyefatsoa ho tsoa liphaepheng tsa tšepe tse se nang sekoli tse nang le khatello e phahameng.
④Li-flange le lifofu
E le ho nolofatsa ho kenya le ho hlokomela, phaephe e atisa ho sebelisoa khokahanong e ka tlosoang, flange ke likarolo tsa khokahano tse sebelisoang haholo.
Bakeng sa ho hlwekisa le ho hlahloba ho hlokahala hore ho hlongoe phaepheng, lesoba la letsoho la phaephe, poleiti e foufetseng kapa e foufetseng e kentswe qetellong ya phaephe. Poleiti e foufetseng e ka boela ya sebediswa ho kwala phaephe ya sebopeho kapa karolo ya phaephe ka nakoana ho sitisa kgokelo le sistimi.
Ka kakaretso, phaephe e nang le khatello e tlase, sebopeho sa foufetseng le flange e tiileng li tšoana, kahoo foufetseng ena e boetse e bitsoa sekoahelo sa flange, foufetseng ena e nang le flange e tšoanang e se e lekantsoe, litekanyo tse itseng li ka fumanoa libukeng tse amehang.
Ho phaella moo, tlhokomelong ea lisebelisoa tsa lik'hemik'hale le liphaephe, e le ho netefatsa polokeho, hangata e entsoe ka poleiti ea tšepe e kentsoeng pakeng tsa li-flange tse peli tsa li-disc tse tiileng, e sebelisetsoang ho arola lisebelisoa kapa liphaephe ka nakoana le sistimi ea tlhahiso. Sefofu sena se bitsoa sefofu sa ho kenya. Sefofu sa ho kenya boholo ba sefofu se ka kenngoa holim'a sekwahelo sa sefofu sa bophara bo lekanang.
