Litlhaloso tsa Tšepe ea U Channel, Litekanyo le Lisebelisoa

1. Litlhaloso
Tekanyetso ea EuropeKanale ea UPNDi-model di rehelletswe ka bophahamo ba letheka la tsona (yuniti: mm). Di na le karolo e tshekaletseng e bōpehileng jwalo ka U mme di-parameter tsa bohlokwa di kenyeletsa:

Bolelele ba letheka (H): Bolelele ka kakaretso ba kanale. Mohlala, bolelele ba letheka ba UPN240 ke 240 mm.

Bophara ba lebanta (B): Bophara ba lebanta. Mohlala, UPN240 e na le lebanta la 85 mm.

Botenya ba letheka (d): Botenya ba lebanta. Mohlala, UPN240 e na le botenya ba letheka ba 9.5 mm.

Botenya ba lebanta (t): Botenya ba lebanta. Mohlala, UPN240 e na le botenya ba lebanta ba 13 mm.

Boima ba khopolo-taba ka mithara: Boima ka bolelele ba yuniti (kg/m). Mohlala, UPN240 e na le boima ba 33.2 kg/m.

Litlhaloso tse Tloaelehileng (Mehlala e sa Tšoaneng):

2. Mofuta oa thepa
Thepa ea tšepe ea kanale ea UPN e tlameha ho fihlela maemo a Europe a EN 10025-2. Likhetho tse tloaelehileng li kenyelletsa:
(1) Lisebelisoa tse tloaelehileng
S235JR: Matla a tlhahiso ≥ 235MPa, theko e tlase, e loketse meaho e sa fetoheng (joalo ka litšehetso tsa leseli).
S275JR: Matla a tlhahiso ≥ 275MPa, matla a leka-lekaneng le a moruo, a sebediswang bakeng sa diforeimi tsa kaho ka kakaretso.
S355JR: Matla a tlhahiso ≥ 355MPa, khetho ea pele bakeng sa mojaro o phahameng, e loketse maemo a khatello e phahameng joalo ka mechini ea koung le litšehetso tsa borokho. Matla a eona a ho thaepa a fihla ho 470 ~ 630MPa, 'me e na le matla a matle a mocheso o tlase.
(2) Lisebelisoa tse khethehileng
Tšepe e matla haholo: joalo ka S420/S460, e sebelisetsoang lisebelisoa tsa matla a nyutlelie le metheo ea mechini e boima haholo (joalo ka UPN350).
Tšepe e tjhesang: tse kang S355J0W, e hanelang ts'enyeho ea sepakapaka, e loketse marokho a kantle.
Tšepe e sa ruseng: e sebelisoa libakeng tse senyang tse kang lik'hemik'hale le tsa leoatle, empa ka litšenyehelo tse phahameng.

(3) Kalafo ea bokaholimo

Botsho bo phutholohileng ka ho chesa: bokaholimo ba kamehla, bo hloka kalafo e latelang ea ho thibela ho bola.

Ho kenya galvanizing ka ho chesa: lera la galvanizing ≥ 60μm (joalo ka tšepe ea kanale bakeng sa tšehetso ea gallery ea liphaephe), e ntlafatsa ho hanyetsa ho bola.

3. Litlhahiso tsa khetho

Maemo a boima bo phahameng (joalo ka lireile tsa crane tsa koung): Beha pele thepa ea UPN300~UPN350 + S355JR ho netefatsa ho kobeha le ho hanyetsa ho beola.

Tikoloho e senyang: Kopanya le galvanizing e tjhesang kapa o sebelise tshepe e tjhesang ka ho toba.

Litlhoko tse bobebe: Letoto la UPN80~UPN120 (boima ba limithara 8.6~13.4kg/m), le loketse li-keel tsa lebota la lesira le litšehetso tsa liphaephe.

Hlokomela: Ha o reka, ho hlokahala ho netefatsa tlaleho ea thepa (ho latela EN 10025-2) le mamello ea litekanyo (EN 10060) ho netefatsa ho latela melao ea projeke.

Khothaletso ea Moetsi oa Channel ea U e Tšepahalang-Royal Group

At Sehlopha sa Borena, re molekane ea ka sehloohong lefapheng la khoebo ea thepa ea tšepe ea indasteri ea Tianjin. Ka boiphihlelo le boitlamo ba ho beha boleng pele, ha rea iketsetsa tšepe e bōpehileng joaloka U feela, empa hape le lihlahisoa tse ling tsohle tsa rona.

Sehlahisoa se seng le se seng se fanoang ke Royal Group se feta ts'ebetsong e thata ea tlhahlobo ea boleng ho netefatsa hore se fihlela kapa se feta maemo a boleng bo holimo. Sena se re thusa ho fa bareki ba rona lihlahisoa tse tšepahalang le tse sireletsehileng tse loketseng lits'ebetso tse fapaneng.
