Mererong ea phepelo ea metsi le ea drainage ea masepala, liphaephe tsa tšepe tse ductile ke bahale ba sa boleloeng, ba netefatsang hore metsi a phalla hantle metseng. Leha ho le joalo, ha u tobane le likhetho tse ngata tse makatsang, u ka khetha e nepahetseng joang? Se tšoenyehe, 'mali ea ratehang! Jindalai Steel Group Co., Ltd. e tla u fa kakaretso e felletseng ea litlhaloso tse fapaneng tsa liphaephe tsa tšepe tse ductile, ho tloha ho K9 ho ea ho K7, sohle seo u se hlokang.
Taba ea pele, ha re buisaneng ka potso ena ea khale: K9 kapa K7? Haeba u hloka liphaephe tse khonang ho mamella khatello ea phepelo ea metsi ea masepala, K9 ke khetho e loketseng. E tšoana le mohale har'a liphaephe tsa tšepe tse ductile, e sebetsanang habonolo le libaka tse nang le khatello e phahameng (≥1.6MPa). Ka lehlakoreng le leng, K7 e tšoana le mothusi oa eona ea nang le bokhoni, e loketse haholoanyane lits'ebetso tsa ho ntša metsi ka litlhoko tse tlase tsa khatello. Ka hona, haeba u batla hore liphaephe tsa hau tsa phepelo ea metsi a tšepe e ductile li fihlelle ts'ebetso e ntle ka ho fetisisa, joale K9 ke khetho e ntle ka ho fetisisa!
Jwale, ha re bueng ka thepa. Polokeho ke ya bohlokwa haholo ha ho tluwa diphaepheng tsa metsi a nowang. O kanna wa ipotsa hore na ke efe e bolokehileng, QT450-10 kapa QT500-7. QT500-7 e tshwana le "molebedi wa tshireletso" wa lefatshe la diphaephe tsa tshepe tse ductile.—e matla, e tšoarellang haholoanyane, le khetho e sireletsehileng bakeng sa litlhoko tsa hau tsa metsi a nooang. Kahoo, haeba u batla hore phepelo ea hau ea metsi e be e hloekileng joalo ka metsi a seliba sa lithaba, khetha QT500-7.
Joale ho thoe'ng ka liphaephe tsa khase ea tlhaho? Na u lokela ho khetha liphaephe tsa tšepe tse ductile kapa liphaephe tsa tšepe? Karabo ke hore: liphaephe tsa tšepe tse ductile li tšoana le motsoalle ea tšepahalang, kamehla li fihla ka nako. Li matla ebile lia tšoarella, li khona ho mamella khatello. Ka lehlakoreng le leng, liphaephe tsa tšepe li bobebe ebile li bonolo ho li tsamaisa, e leng se etsang hore e be khetho e ntle lits'ebetsong tse itseng. Ho itšetlehile haholo ka litlhoko tsa hau tse ikhethileng, empa ka bobeli li na le melemo ea tsona. Hopola, tlas'a maemo a thata, liphaephe tsa tšepe tse ductile ke khetho e tšepahalang!
Jwale, ha re bueng ka ho kenya. Ha ho tluwa tabeng ya diphaephe tse patilweng, o ka ipotsa hore na ke efe e loketseng haholoanyane: diphaephe tsa tshepe tse ductile tsa mofuta wa sokete kapa diphaephe tsa tshepe tse ductile tse flanged. Diphaephe tsa mofuta wa sokete di tshwana le motswalle ya bonolo, di loketse tikoloho efe kapa efe, mme di bonolo haholo ho di kenya. Diphaephe tsa mofuta wa flange di rarahane hanyane, empa kgokelo e sireletsehile haholoanyane mme e ka mamella kgatello e phahameng. Kahoo, haeba boiketlo e le ntho ya bohlokwa ho wena, diphaephe tsa mofuta wa sokete ke kgetho ya hao e molemohali!
Joale, u khetha joang pakeng tsa bophara bo bonyenyane bo khathatsang (≤100mm) le bophara bo boholo (≥Liphaephe tsa tšepe tse ductile tsa 800mm? Mekhoa ea tsona ea khetho e makatsa feela. Bakeng sa liphaephe tse bophara bo bonyenyane, o hloka ho tsepamisa maikutlo holima sekhahla sa phallo le litlhoko tsa khatello. Bakeng sa liphaephe tse bophara bo boholo, o hloka ho nahana ka tikoloho ea ho kenya le monyetla oa ho bola.
Ha ho tluoa tabeng ea ho bola, haeba u sebetsana le liphaephe tsa metsi a litšila a asiti le a alkali, u ka 'na ua taboha pakeng tsa ho sebelisa liphaephe tse tloaelehileng tsa tšepe tse ductile kapa liphaephe tse nang le liphaephe tse thibelang ho bola (tse kang tar ea mashala ea epoxy kapa polyurethane). Karabo e bonolo: khetha liphaephe tse koahetsoeng! Li tšoana le seaparo sa pula bakeng sa sefefo.—ho bolokehile ho feta ho kopa tšoarelo!
Ka bokhutšoanyane, ebang o hloka liphaephe tsa tšepe tse nang le ductile tse bohareng kapa o ntse o nahana hore na o tla khetha mofani ofe oa liphaephe tsa tšepe tse nang le ductile, hopola hore Jindalai Steel Group ke motšehetsi oa hau ea tšepahalang kamehla. Ka tlhahisoleseling e nepahetseng le metlae e menyenyane, o ka tsamaea lefatšeng la liphaephe tsa tšepe tse nang le ductile habonolo joaloka setsebi. Kahoo ha re phahamisetseng khalase ho bahale ba sa rorisoang ba kenyang letsoho ka khutso kahong ea meralo ea rona ea motheo.—Liphaephe tsa tšepe tse nang le ductile! Litumeliso!
