Boenjiniere ba kaho le ba sechaba, khetho ea thepa e bohlokoa ho netefatsa botšepehi le bophelo bo bolelele ba sebopeho. Ntho e 'ngoe e hlomphuoang haholo indastering ke pipe ea ASTM A252. Litlhaloso li akaretsa liphaephe tsa lipeipi tsa cylindrical, tse bohlokoa haholo lits'ebetsong tse fapaneng, haholo ho boenjiniere ba motheo. Ho blog ena, re tla teba ka botebo ka lintlha tsa bohlokoa le ts'ebeliso ea boholo ba liphaephe tsa ASTM A252 ha re ntse re totobatsa bokhoni ba moetsi ea ka sehloohong ea thehiloeng Cangzhou, Profinseng ea Hebei.
Lintlha tse ka sehloohong tsa liphaephe tsa ASTM A252
ASTM A252 ke tlhaloso e tloaelehileng e hlalosang litlhoko tsa liphaephe tsa tšepe tse cheselitsoeng le tse se nang seam. Liphaephe tsena li etselitsoe ho sebelisoa e le litho tse jarang moroalo oa ka mehla kapa e le likhetla tsa liqubu tsa konkreite tse kentsoeng sebakeng. Lintlha tsa bohlokoa tsa ASTM A252 li kenyelletsa:
1. Kereiti ea Material: Tlhaloso e kenyelletsa limaraka tse tharo tsa tšepe: Kereiti ea 1, Kereiti ea 2, le Kereiti ea 3. Sehlopha se seng le se seng se na le tlhokahalo e fapaneng ea matla a tlhahiso, 'me Kereiti ea 3 e na le matla a phahameng ka ho fetisisa a tlhahiso 'me e loketse likopo tse boima.
2. Boholo: Liphaephe tsa ASTM A252 li fumaneha ka mefuta e sa tšoaneng ea marako, e lumellang ho fetoha ha maemo ho moralo le ho sebelisoa. Liphaephe tsena li fumaneha ka bophara ho tloha ho lisenthimithara tse 6 ho isa ho tse 60 ho finyella litlhoko tse sa tšoaneng tsa morero.
3. Likhetho tse cheselitsoeng le tse se nang seamless:ASTM A252 pipee ka hlahisoa e cheselitsoe kapa e se na seamless, e fana ka likhetho tse ipapisitseng le litlhoko tse ikhethang tsa projeke ea hau. Peipi e cheselitsoeng ka kakaretso e na le litšenyehelo tse ngata, ha phala e se nang moeli e fana ka matla a maholo le ho tšepahala.
4. Ho hanyetsa kutu: Ho itšetlehile ka kopo, liphaephe tsa ASTM A252 li ka koaheloa kapa tsa phekoloa ho matlafatsa ho hanyetsa ha tsona, ho netefatsa hore li sebelisoa nako e telele esita le libakeng tse thata.
ASTM A252 Likopo tsa Pipe
Ho feto-fetoha ha phala ea ASTM A252 ho etsa hore e tšoanelehe bakeng sa mefuta e mengata ea lits'ebetso, ho kenyelletsa:
- Lithako tsa Motheo: Hangata liphaephe tsena li sebelisoa e le liqubu tsa motheo mererong ea kaho, li fana ka tšehetso e hlokahalang bakeng sa meaho, marokho le meaho e meng.
- Mehaho ea Marine: Lipeipi tsa ASTM A252 li loketse hantle bakeng sa ho sebelisoa libakeng tsa leoatle 'me li ka sebelisoa kahong ea li-docks, piers le platforms offshore.
- Mabota a Sireletsang: Matla le nako e telele ea liphaephe tsena li etsa hore li tšoanelehe bakeng sa ho sebelisoa maboteng a bolokang, a thusang ho tsitsisa mobu le ho thibela khoholeho.
- Lithako tsa Konkreite tse betliloeng: Ha li sebelisoa e le qubu ea liqubu tsa konkreite tse behiloeng sebakeng,ASTM A252pipe e fana ka moralo o tiileng o matlafatsang botšepehi ba sebopeho sa konkreite.
Moetsi ea ka sehloohong Cangzhou
Moetsi ea tsebahalang ea fumanehang Cangzhou, Profinseng ea Hebei, esale a hlahisa liphaephe tsa boleng bo holimo tsa ASTM A252 ho tloha ha e thehoa ka 1993. Khampani e akaretsa sebaka sa lisekoere-mithara tse 350,000, e na le thepa eohle ea RMB 680 milione, 'me e hira basebetsi ba ka bang 680 ba nang le tsebo. Moetsi o ikemiselitse ho fana ka lihlahisoa tse fihlelang litekanyetso tse tiileng tsa boleng, ho netefatsa hore liphaephe tsa eona tsa ASTM A252 lia tšepahala ebile lia tšoarella lits'ebetsong tse fapaneng.
E tsepamisitse maikutlo ho boqapi le khotsofalo ea bareki, k'hamphani e fetohile moetapele oa indasteri, e fanang ka tharollo ea tloaelo ho fihlela litlhoko tse ikhethang tsa bareki ba eona. Ka lisebelisoa tsa morao-rao le basebetsi ba nang le phihlelo, ba khona ho hlahisa liphaephe ka mokhoa o phahameng ka ho fetisisa, ho etsa hore e be molekane ea tšeptjoang bakeng sa merero ea kaho le ea boenjiniere.
ha re phethela
Qetellong, lipeipi tsa ASTM A252 ke karolo ea bohlokoa ea kaho ea sejoale-joale, e fanang ka lintlha tsa bohlokoa tse fihlelang litlhoko tsa mefuta e fapaneng ea lits'ebetso. Ka moetsi ea tsebahalang oa Cangzhou ea hlahisang liphaephe tsena, indasteri e ka itšetleha ka thepa ea boleng bo holimo ho netefatsa polokeho le botsitso ba sebopeho. Hore na e sebelisetsoa boenjiniere ba motheo, meaho ea metsing kapa mabota a bolokang, liphaephe tsa ASTM A252 ke khetho ea bohlokoa bakeng sa baenjiniere le lihahi.
