Introduction to Ductile Iron Pipe Systems: Strength, Durability, and Reliability

Ho tloha ha e qala ka 1955, phala ea tšepe ea ductile e bile tharollo e ratoang bakeng sa lits'ebetso tsa sejoale-joale tsa metsi le litšila, tse tsebahalang ka matla a eona a ikhethang, ho tšoarella, le ho ts'epahala ha ho tsamaisa metsi a tala le a nooang, likhoerekhoere, li-slurries le lik'hemik'hale tse sebetsang.

E entsoe le ho etsoa ho finyella litekanyetso tse thata ka ho fetisisa tsa indasteri, phala ea tšepe ea ductile ha e mamelle feela mathata a lipalangoang le ho kenngoa empa e boetse e ipaka e tiile maemong a ts'ebetso a thata ka ho fetisisa. Ho tloha hamore ea metsi e mamellang ho ea ho pholletsa le mobu o leqhoa, ho buisana ka liforo tse tebileng, le ho shebana le libaka tse phahameng tsa metsi, libaka tse ngata tsa sephethephethe, litšepe tsa linōka, mehaho ea tšehetso ea liphaephe, liforo tse majoe, esita le mobu o fetohang, o pharaletseng le o sa tsitsang - phala ea tšepe ea ductile e nyolohela ho phephetso.

Ho feta moo, tšepe ea ductile e ka phekoloa ka mekhoa e fapaneng ea ho roala ho matlafatsa ponahalo ea eona le tšireletso. Khetho ea liaparo e etselitsoe ho lumellana le tikoloho e khethehileng ea tšebeletso le likhetho tsa botle. Ka tlase, re hlahlobisisa likhetho tse fapaneng tsa ho roala tse loketseng tšepe ea ductile, e sebetsanang le maemo a sepakapaka le ho kenya liphaephe tse patiloeng ka tlas'a lefatše.

Liaparo

Ductile iron e fana ka monyetla oa ho alafshoa ka mefuta e fapaneng ea litsamaiso tsa ho roala, tse sebeletsang molemong oa ntlafatso ea botle le ts'ireletso. Khetho ea liaparo e itšetlehile ka litšobotsi tse ikhethang tsa tikoloho ea tšebeletso le sephetho se lakatsehang sa botle. Ka tlaase mona, re hlahloba mekhoa e fapaneng ea ho roala e loketseng tšepe ea ductile, e sebetsanang le maemo a mabeli a holimo ho maemo a sepakapaka le ho kenngoa ka tlas'a lefatše bakeng sa liphaephe tse patiloeng.
