Mekhoa ena ea ho phekola bokaholimo e sireletsa tšepe ea liphaephe ka katleho ho senyeheng le ho senyeheng, e netefatsa ho tšepahala ha eona le ho tšoarella ha eona libakeng tse fapaneng tse thata.

Sephutheloana le Lipalangoang:

Womic Steel e netefatsa sephutheloana se sireletsehileng le tsamaiso e tšepahalang ea tšepe ea lipeipi, e fana ka likhetho tse tenyetsehang ho fihlela litlhoko tse fapaneng tsa bareki:

1. Thepa e Kgolo: Bakeng sa diotara tse kgolo, tshepe ya diphaephe e ka romelwa ka bongata ho sebediswa dijari tse ikgethang tsa thepa e kgolo. Tshepe e kenngwa ka ho toba ka hara sekepe ntle le ho paka, e loketse ho tsamaiswa ka bongata bo bongata ka theko e tlase.
2. LCL (Mojaro o ka Tlase ho Setshelo): Bakeng sa diotara tse nyane, tshepe ya phaephe e ka romelwa e le thepa ya LCL, moo diotara tse ngata tse nyane di kopanngwang setshelong se le seng. Mokgwa ona o theko e tlase bakeng sa bongata bo bonyenyane mme o fana ka dikemiso tse tenyetsehang tsa ho tlisa thepa.
3. FCL (Mojaro o Felletseng wa Setshelo): Bareki ba ka kgetha ho romelwa ha FCL, moo setshelo se felletseng se nehetsweng ho odara ya bona. Mokgwa ona o fana ka dinako tse potlakileng tsa ho tsamaisa thepa mme o fokotsa kotsi ya tshenyo nakong ya ho e tshwara.
4. Thepa ea Moeeng: Bakeng sa liodara tse potlakileng, thepa ea moeeng e fumaneha bakeng sa ho romelloa ka potlako. Le hoja e le theko e boima ho feta thepa ea leoatleng, thepa ea moeeng e fana ka lipalangoang tse potlakileng le tse tšepahalang bakeng sa thepa e amang nako.

Womic Steel e netefatsa hore thepa eohle e romelloang e phuthetsoe ka mokhoa o sireletsehileng ho thibela tšenyo nakong ea lipalangoang. Hangata tšepe e phuthetsoe ka thepa e sireletsang 'me e tiisitsoe ka har'a lijana kapa liphaleteng ho netefatsa botsitso nakong ea lipalangoang. Ho feta moo, k'hamphani e sebetsa haufi-ufi le balekane ba tšepahalang ba likepe ho netefatsa hore thepa e romelloang ka nako e loketseng le tsamaiso e sebetsang ea thepa.

Maemo a Kopo:

Liphaephe tsa mohala tsa API 5L tse hlahisoang ke Womic Steel li sebelisoa haholo indastering ea peterole le khase ea tlhaho bakeng sa ho tsamaisa oli, khase le maro a mang. Li boetse li sebelisoa indastering e meng e fapaneng e kang ts'ebetso ea lik'hemik'hale, tlhahiso ea motlakase le kaho.

Qetello:

Womic Steel ke moetsi ea tšepahalang oa liphaephe tsa mohala tsa API 5L, o fanang ka lihlahisoa tsa boleng bo holimo tse fihlelang litlhoko tse thata tsa indasteri ea peterole le khase ea tlhaho. Ka ho shebana le boleng, botšepehi le khotsofalo ea bareki, Womic Steel e ntse e le khetho e ratoang bakeng sa bareki lefatšeng ka bophara.
