Li-tag tsa Sehlahisoa

Ho hlahisa likhetho tsa rona tsa qubu tse theko e tlaase: tharollo ea mantlha bakeng sa litlhoko tsa hau tsa kaho. Khamphaning ea rona, re motlotlo ka ho fana ka spiral welded ea boleng bo holimoho kenya lipeipi tsa tšepetse etselitsoeng ho mamella le maemo a thata ka ho fetisisa. Ho sa tsotellehe hore na u ameha kahong ea borokho, nts'etsopele ea litsela kapa mohaho o phahameng oa mohaho o phahameng, liqubu tsa rona li u fa motheo o ka tšeptjoang ho netefatsa nako e telele le botsitso ba morero oa hau.

E entsoe ho sebelisoa theknoloji ea morao-rao, liphaephe tsa rona tsa spiral welded steel pipe li etselitsoe ho kopana le litlhoko tse thata tsa mefuta e mengata ea likopo. Kaho ea bona e matsutla-tsutla e tiisa ts'ebetso e holimo, e etsa hore e be tse loketseng borakonteraka le lihahi tse batlang ho tšoarella ntle le ho roba banka. Re utloisisa hore ho boloka litšenyehelo ke ntho e ka sehloohong 'marakeng oa kajeno oa tlhōlisano, ke ka lebaka leo liphaephe tsa qubu tseo re fanang ka tsona e le khetho e theko e tlaase ntle le ho sekisetsa boleng.

Boitlamo ba rona ho khotsofalo ea bareki ke khubu ea tsohle tseo re li etsang. Ho theosa le lilemo, re iketselitse botumo ba ho tsepamisa maikutlo ho bareki le ho fana ka litšebeletso tse felletseng tsa thekiso ea pele, thekiso le lits'ebeletso tsa kamora thekiso. Boinehelo bona bo tiisa hore re fihlela litlhoko tsohle tsa bareki ba rona, re fana ka lihlahisoa le litšebeletso tse lulang li tumme.

Q1: Piling Steel Pipe ke eng?

Liphaephe tsa tšepe tse tlatsitsoeng ke mehaho e matla ea cylindrical e sebelisetsoang ho tšehetsa meaho le meaho e meng. Li khannoa ka botebo fatše ho fana ka botsitso le bokhoni ba ho jara, ho etsa hore e be tsa bohlokoa mererong ea kaho, haholo-holo libakeng tse nang le maemo a fokolang a mobu.

Q2: Ke hobane'ng ha u khetha spiral welded khōlō bophara tšepe qubu liphaephe?

Liphaephe tse cheselitsoeng ka spiral li tsebahala ka matla le ho tšoarella ha tsona. Ts'ebetso ea spiral welding e lumella li-diameter tse kholoanyane, tse ka tšehetsang meroalo e meholo. Sena se etsa hore e be tse loketseng merero e meholo ea kaho moo mekhoa ea khale ea ho bokella liqubu e ka sitoang ho fihlela litlhoko.

Q3: Nka fumana likhetho tse fumanehang joang?

Ho fumana ka theko e tlaasepeipi ea ho bokelladikgetho ha ho bolele ho tela boleng. Khamphani ea rona e etelletsa pele khotsofalo ea bareki ka ho fana ka mefuta e fapaneng ea litlhaloso ho lumellana le tlhoko e 'ngoe le e' ngoe. Re etsa bonnete ba hore lihlahisoa tsa rona li rekoa ka tlholisano ntle le ho itima boleng. Litšebeletso tsa rona tse netefalitsoeng tsa thekiso ea pele, thekisong le ka mor'a thekiso li netefatsa hore u fumana tšehetso e felletseng nakong eohle ea ho reka.

Q4: Ke lokela ho nahana ka eng ha ke reka?

Ha u khetha phala ea tšepe bakeng sa ho bokella, nahana ka lintlha tse kang bophara, boleng ba thepa le litlhoko tse khethehileng tsa morero. Sehlopha sa rona se ikemiselitse ho u thusa ho etsa liqeto tsena, ho netefatsa hore u fumana tharollo e lumellanang hantle le litlhoko tsa hau.
