Tshebetso e ikgethang ya tlhahiso e etsa hore diphaephe tsena di be matla le ho tshwarella haholoanyane, di kgone ho mamella kgatello e phahameng ya ka hare le ya kantle. Bokgoni ba ho hanela mafome le ho fetoha ha tsona bo etsa hore e lokele mefuta e mengata ya ditshebediso, ho kenyeletswa diphaephe tsa metsi le ho tjheseletsa diphaephe tsa tshepe.

2. Liphaephe tsa metsi:

Litsamaisong tsa kabo ea metsi, ho fana ka metsi a hloekileng ka mokhoa o sireletsehileng le o sebetsang hantle ho bohlokoa. Phaephe ea tšepe ea carbon e kopantsoeng ka spiral e ipakile e le khetho e tšepahalang bakeng sa liphaephe tsa metsi ka lebaka la thepa ea eona e sa senyeheng ke mafome. Bokaholimo bo boreleli ba liphaephe tsena bo fokotsa khohlano, bo netefatsa phallo e sa khaotseng ea metsi le ho fokotsa moferefere. Ho feta moo, matla a tlhaho le ho tšoarella li tiisa tšireletso khahlanong le ho lutla, ho robeha le ho hloleha ha sebopeho, ho netefatsa phepelo e tsoelang pele le e tšepahalang ea metsi.

3. Ho tjheseletsa liphaephe tsa tšepe:

Indasteri ea ho tjheseletsa e itšetlehile haholo ka phaephe ea tšepe ea khabone e tjheseletsoeng ka spiral bakeng sa lits'ebetso tse fapaneng. Matla a ikhethang le ho tenyetseha ha liphaephe tsena li etsa hore li be ntle bakeng sa ho tjheseletsa liphaephe tsa tšepe. Ebang ho hahoa litanka tse kholo tsa polokelo, liphaephe tsa ho tsamaisa oli le khase, kapa likarolo tsa sebopeho libakeng tsa indasteri, liphaephe tsa tšepe ea khabone e tjheselitsoeng ka spiral li bapala karolo ea bohlokoa. Ho tšoana ha manonyeletso a tjheseletsoeng ho netefatsa ho tšepahala le polokeho ea sebopeho, ho fokotsa tlhoko ea tlhokomelo kapa litokiso khafetsa.

4. Melemo le melemo:

4.1 Tharollo e theko e tlaase: Phaephe ea tšepe ea carbon e tjheseletsoeng ka spiral e fana ka tharollo e theko e tlaase bakeng sa ho tjheseletsa liphaephe tsa metsi le tsa tšepe. Ho tšoarella ha tsona le ho hanyetsa mafome li netefatsa bophelo ba ts'ebeletso e telele, ka hona ho fokotsa litšenyehelo tsa ho nkela sebaka le tlhokomelo.

4.2 Ho bonolo ho kenya: Theknoloji ea ho tjheseletsa e potolohang e sebelisoang ts'ebetsong ea tlhahiso e ka hlahisa liphaephe tse telele le tse tsoelang pele, e fokotsang tlhoko ea manonyeletso a khafetsa. Moralo ona o nolofalitsoeng o nolofatsa ts'ebetso ea ho kenya, o boloka nako le boiteko.

4.3 Ho feto-fetoha ha maemo: Liphaephe tsa tšepe ea khabone tse phuthetsoeng ka spiral li fumaneha ka bophara le botenya bo fapaneng, e leng se li lumellang ho ikamahanya le lits'ebetso tse fapaneng. Li ka etsoa hore li lumellane le litlhoko tse itseng tsa projeke, li ikamahanya le mefuta e fapaneng ea maro, likhatello le mocheso.

4.4 Tšireletso ea tikoloho: Tšepe ea khabone ke thepa e ka sebelisoang hape e thusang ho boloka tikoloho e tsitsitse. Liphaephe tsa tšepe ea khabone tse bōpehileng joaloka spiral tse kopantsoeng li ka sebelisoa hape le ho sebelisoa hape, ho fokotsa litšila le ho sireletsa mehloli ea tlhaho.

Ha re phethela:

Bokhoni le melemo ea liphaephe tsa tšepe ea carbon tse welded ka har'a liphaephe tsa metsi leho tjheseletsa phala ea tšepee ke ke ea nyenyefatsoa. Phetiso e sebetsang hantle le e tšepahalang ea metsi le maro a indasteri e itšetlehile haholo ka ho tšoarella ha tsona, ho hanyetsa mafome le bonolo ba ho li kenya. Ha tlhoko ea meralo ea motheo e matla le e theko e tlaase e ntse e eketseha, liphaephe tsa tšepe ea khabone tse welletsoeng ka spiral li tla lula e le karolo ea bohlokoa ho netefatseng ts'ebetso e boreleli ea litsamaiso tsa metsi le lits'ebetso tsa indasteri lefatšeng ka bophara.
