Pipe ea Tšepe ea Ductile e Boima Bokae​

Boenjiniere ba phepelo ea metsi le drainage, marangrang a liphaephe tsa masepala, le litsamaiso tsa liphaephe tsa indasteri,phala ea tšepe e ductilee se e le sebaka se setle sa liphaephe tsa tšepe tsa setso le tsa tšepe ka lebaka la thepa ea tsona e ntle ea mechini le ho hanyetsa mafome. Ho utloisisa likarolo tsa bohlokoa tsa botekgeniki tsa phaephe ea tšepe e ductile ho bohlokoa bakeng sa baqapi, bareki le lik'hamphani tsa kaho, ebang ke bakeng sa phepelo ea metsi a mangata kapa lipalangoang tsa likhoerekhoere. Sengoloa sena se tla nkaDINSEN ductile tšepe phaephee le mohlala ho hlalosa ka mokhoa o hlophisehileng litlhaloso tsa eona, boima, khatello ea ho sebetsa le litšobotsi tsa ho roala.

I. Litlhaloso le Litekanyo tsa Pipe ea Tšepe ea Ductile: Mokhoa oa ho Fumana Mohlala?

Ha ho kgethwa diphaephe, ho hlokahala pele ho hlakiswa boholo le boholo ba phaephe ya tshepe e ductile. Maemo a matjhaba a itshetlehile haholo ho ISO 2531 kapa EN 545, a hlophisitsweng ka bophara ba nominal (DN).

Ha re nka phaephe ea tšepe e ductile ea DINSEN mohlala, liphaephe tsa K9 grade (bophahamo bo tloaelehileng ba lebota) li sebelisoa hangata, ka bophara bo tloaelehileng bo tlohang ho DN80 ho isa ho DN2000. Mona ke boholo bo tloaelehileng ba liphaephe:

• DN80: Bophara ba kantle 98mm, botenya ba lebota 6.0mm
• DN100: Bophara ba kantle 118mm, botenya ba lebota 6.0mm
• DN200: Bophara ba kantle 222mm, botenya ba lebota 6.3mm
• DN400: Bophara ba kantle 429mm, botenya ba lebota 8.1mm
• DN1000: Bophara ba kantle 1048mm, botenya ba lebota 13.5mm

Mekhahlelo e fapaneng ea botenya ba lebota (K8, K9, K10, K12) e tla ama bokhoni ba ho jara khatello le boima ba yuniti ea phaephe.Basebelisi ba ka khetha ka nepo ho latela khatello ea moralo.

II. Boima ka mithara ea phaephe ea tšepe e ductile: Phaephe ea tšepe e ductile e boima bo bokae?

Potso e tloaelehileng thekong ea boenjiniere ke ena: Phaephe ea tšepe e ductile e boima bo bokae? Boima ba phaephe ea tšepe e ductile bo bopiloe ke boima ba 'mele oa phaephe le boima ba sokete, e leng se amang ka kotloloho litšenyehelo tsa lipalangoang, ho phahamisa le ho kenya.

Ha re nka phaephe ea tšepe ea ductile ea DINSEN K9 (bolelele bo tloaelehileng ba limithara tse 6) e le mohlala, boima ba khopolo-taba ke bo latelang:

• DN100: Hoo e ka bang 15.1 kg/m → 95 kg ka phaephe
• DN200: Hoo e ka bang 30.6 kg/m → 194 kg ka phaephe
• DN300: Hoo e ka bang 50.8 kg/m → 323 kg ka phaephe
• DN500: Hoo e ka bang 104.3 kg/m → 669 kg ka phaephe
• DN800: Hoo e ka bang 215.2 kg/m → 1394 kg ka phaephe

Boima ba 'nete bo ka fapana hanyane ka lebaka la lintlha tse kang botenya ba sekoahelo sa zinki le lesela la seretse sa samente se ka hare. DINSEN e ka fana ka maqephe a nepahetseng a ho bala boima bakeng sa tekanyetso ea projeke le moralo oa thepa.

III. Khatello e Sebetsang ea Ductile Iron Pipe

Phaephe ea tšepe ea Ductile e na le matla a ho tsikinyeha a phahameng le matla a ho hatella a potolohang. Phaephe ea tšepe ea ductile ea sehlopha sa K9 hangata e na le khatello ea ho sebetsa ea li-bar tse 16 (1.6 MPa), ha maemo a botenya ba lebota a phahameng (joalo ka K12) a loketse lits'ebetso tsa khatello ea li-bar tse 25 kapa esita le li-bar tse 40.

Liphaephe tsa tšepe tse ductile tsa DINSEN li etsoa ka tieo ho latela maemo a ISO 2531. Phaephe e 'ngoe le e 'ngoe e feta tekong ea hydrostatic pele e tloha fekthering ho netefatsa hore ntlha ea polokeho e phahame ka makhetlo a 1.5 ho feta khatello ea moralo e sebetsang, e leng se etsang hore li tšoanelehe haholo bakeng sa phetiso ea metsi a hole, liphaephe tse phahamisang seteishene sa ho pompa, le liphaephe tsa indasteri tse nang le khatello e phahameng.

IV. Sekoahelo sa Zinki bakeng sa Tšireletso ea Mafome

Karolo ea ho Koahela Zinki Liphaepheng tsa Tšepe tsa Ductile E 'ngoe ea mehato ea bohlokoa ka ho fetisisa ea tšireletso bakeng sa liphaephe tse patiloeng ke ho koahela zinki liphaepheng tsa tšepe tsa ductile. Koahelo ea zinki ha e fane feela ka tšireletso ea cathodic empa hape e theha sistimi e kopaneng ea ho thibela ho bola ka pente ea kantle kapa sheathing ea polyethylene.

Liphaephe tsa tšepe tse ductile tsa DINSEN li tla ka mokhoa o tloaelehileng ka sekoahelo sa zinki sa ≥200 g/m² (ho ea ka tekanyetso ea ISO 8179), se koahetsoeng ka asphalt e khubelu ea epoxy kapa lera la ho qetela la polyurethane, e ntlafatsang haholo ho hanyetsa ho bola le bophelo ba nako. Bakeng sa mobu o senyang kapa libaka tse nang le khanyetso e phahameng, sekoahelo se eketsehileng sa zinki + filimi ea PE kapa sekoahelo se felletseng sa polyurethane sea fumaneha, ka bophelo ba tšebeletso bo etselitsoeng lilemo tse 50-100.

V. Ke Hobane'ng ha U Lokela ho Khetha Liphaephe tsa Tšepe tsa DINSEN Ductile?

Jwalo ka mofani wa diphaephe tsa tshepe tse ductile tsa profeshenale, DINSEN e fana ka mefuta e felletseng ya ditlhaloso ho tloha ho DN80 ho isa ho DN2000, e tshehetsang botenya bo fapaneng ba mabota jwalo ka K8, K9, K10, le K12, mme e ka iketsetsa bolelele, mahlakore a kahare (seretse sa samente/resin ya epoxy), le ditharollo tsa tshireletso ya mafome ya kantle ho fihlela ditlhoko tsa bareki.

Liphaephe tsohle tsa tšepe tse ductile li netefalitsoe ke ISO 2531 / EN 545. Litafole tse felletseng tsa boima, litekanyo, khatello ea ho sebetsa, le liparamente tsa ho roala tsa zinki lia fumaneha. Liphutheloana tsa kantle ho naha tsa machabeng le lits'ebeletso tsa thepa tse emisang hang lia tšehetsoa.

Bakeng sa boholo le litekanyo tse qaqileng tsa phaephe ea tšepe e ductile, litafole tsa khetho kapa lisebelisoa tsa ho bala boima, ka kopo etelaDINSENkapa ikopanye le sehlopha sa thekiso sa botekgeniki ka kotloloho.
