Phaephe e sekwere ke lebitso la phaephe e sekwere le phaephe e khutlonnetsepa, ke hore, phaephe ea tšepe e bolelele bo lekanang le bo sa lekanang ba lehlakore. E entsoe ka tšepe e phutholohileng ka mor'a kalafo ea ts'ebetso. Ka kakaretso, tšepe e phutholohileng e a pakoa, ea batalatsoa, ​​ea kobeha le ho kopanngoa ho etsa phaephe e chitja, ebe e phuthoa ka phaephe e sekwere ho tsoa phaepheng e chitja, ebe e khaoloa ka bolelele bo hlokahalang.

1. Phapang e dumelletsweng ya botenya ba lebota la phaephe e sekwere e ke ke ya feta 10% ya botenya ba lebota bo tlwaelehileng ha botenya ba lebota bo sa fete 10mm, hammoho le 8% ya botenya ba lebota ha botenya ba lebota bo feta 10mm, ntle le botenya ba lebota ba dikhutlo le dibaka tsa ho weld.

2. Bolelele bo tloaelehileng ba phaephe e khutlonnetsepa e sekwere ke 4000mm-12000mm, boholo ba yona ke 6000mm le 12000mm. Phaephe e khutlonnetsepa e dumellwa ho fana ka dihlahiswa tse bolelele bo bokgutshwane le bo sa tsitsitseng tse seng ka tlase ho 2000mm, mme e ka boela ya tliswa ka sebopeho sa phaephe ya sebopeho, empa Demander e tla kgaola phaephe ya sebopeho ha e e sebedisa. Boima ba gauge e kgutshwane le dihlahiswa tse sa tsitsitseng tsa gauge ha di a lokela ho feta 5% ya bophahamo bohle ba phaephe. ​​Bakeng sa diphaephe tse khutlonnetsepa tse nang le boima ba theory bo fetang 20kg / m, ha di a lokela ho feta 10% ya bophahamo bohle ba phaephe.

3. Tekanyo ea ho kobeha ha phaephe e sekwere e khutlonnetsepa ha ea lokela ho feta 2mm ka mithara, 'me tekanyo eohle ea ho kobeha ha ea lokela ho feta 0.2% ea bolelele bohle.

Ho ya ka tshebetso ya tlhahiso, diphaephe tse sekwere di arotswe ka diphaephe tse sekwere tse se nang modumo tse phuthilweng ka ho tjhesa, diphaephe tse sekwere tse se nang modumo tse hulwang ka serame, diphaephe tse sekwere tse se nang modumo tse ntshitsweng le diphaephe tse sekwere tse welditsweng.

Phaephe e sekwere e welletsoeng e arotsoe ka

1. Ho ya ka tshebetso – tube ya sekwere ya ho tjheseletsa ya arc, tube ya sekwere ya ho tjheseletsa ya kganyetso (maqhubu a phahameng le maqhubu a tlase), tube ya sekwere ya ho tjheseletsa ya kgase le tube ya sekwere ya ho tjheseletsa ya ontong

2. Ho ya ka weld – phaephe e sekwere e welded e otlolohileng le phaephe e sekwere e welded e spiral.

Tlhophiso e tloaelehileng ea tlhahiso

Tube e sekwere e arotsoe ka tube e tloaelehileng ea naha e sekwere, tube e sekwere e tloaelehileng ea Japane, tube e sekwere e tloaelehileng ea Brithani, tube e sekwere e tloaelehileng ea Amerika, tube e sekwere e tloaelehileng ea Europe le tube e sekwere e seng ea maemo ho latela maemo a tlhahiso.

Tlhophiso ea sebopeho sa karolo

Liphaephe tse sekwere li arotsoe ho latela sebopeho sa karolo:

1. Phaephe e sekwere e bonolo: phaephe e sekwere, phaephe e kgutlonnetsepa.

2. Phaephe e sekwere e nang le karolo e rarahaneng: phaephe e sekwere e bōpehileng joaloka lipalesa, phaephe e bulehileng e sekwere, phaephe e sekwere e kobehileng le phaephe e sekwere e bōpehileng joaloka e khethehileng.

Liphaephe tse sekwere li arotsoe ka liphaephe tse sekwere tse nang le galvanized e chesang, liphaephe tse sekwere tse nang le galvanized ea motlakase, liphaephe tse sekwere tse tlotsitsoeng ka oli le liphaephe tse sekwere tse nang le asene ho latela kalafo ea bokaholimo.

Sebelisa sehlopha

Li-tube tse sekwere li arotsoe ka tšebeliso: li-tube tse sekwere bakeng sa mokhabiso, li-tube tse sekwere bakeng sa lisebelisoa tsa lisebelisoa tsa mochini, li-tube tse sekwere bakeng sa indasteri ea mechini, li-tube tse sekwere bakeng sa indasteri ea lik'hemik'hale, li-tube tse sekwere bakeng sa sebopeho sa tšepe, li-tube tse sekwere bakeng sa kaho ea likepe, li-tube tse sekwere bakeng sa likoloi, li-tube tse sekwere bakeng sa maballo a tšepe le likholomo, le li-tube tse sekwere bakeng sa merero e khethehileng.

Sehlopha sa botenya ba lebota

Lipeipi tse khutlonnetsepa li arotsoe ho latela botenya ba lebota: lipeipi tse teteaneng haholo tse khutlonnetsepa tse nang le mabota a mane, lipeipi tse teteaneng tse khutlonnetsepa tse nang le mabota a mane le lipeipi tse tšesaane tse khutlonnetsepa. Feme ea rona e na le theknoloji ea tlhahiso 'marakeng, 'me e na le boiphihlelo bo boholo. Rea u amohela metsoalle ea machaba ho tla u thusa. Re tla leka ka hohle ho fihlela litlhoko tsa hau tse fapaneng.
