Ukubuka konke kweDuctile Iron Pipe
Amapayipi e-Ductile Iron angamapayipi enziwe ngensimbi ethambile. I-Ductile iron iyinsimbi ethambile ye-graphite ene-spheroidized. Izinga eliphezulu lokuthembeka kwensimbi ethambile libangelwa kakhulu amandla ayo aphezulu, ukuqina, kanye nokumelana nokugqwala. Amapayipi ensimbi ethambile avame ukusetshenziselwa ukusatshalaliswa kwamanzi aphuzwayo kanye nokupompa ama-slurries, indle kanye namakhemikhali enqubo. Lawa mapayipi ensimbi ayintuthuko eqondile yamapayipi ensimbi angaphambilini asecishe ayishintsha manje. Izinga eliphezulu lokuthembeka kwamapayipi ensimbi ethambile kungenxa yezakhiwo zawo ezahlukahlukene eziphakeme. Lawa mapayipi angamapayipi afunwa kakhulu ezinhlotsheni eziningana zokusebenza.

Amabanga Amathathu Ayinhloko Epayipi Lensimbi Ebunjiwe
I-V-2 (isigaba 40) I-Grey Iron, i-V-3 (65-45-12) I-Ductile Iron, kanye ne-V-4 (80-55-06) I-Ductile Iron. Zinikeza amandla okucindezela amahle kakhulu kanye nekhono eliphezulu lokudambisa ukudlidliza.
V-2 (isigaba 40) I-Grey Iron, i-ASTM B48:
Leli banga linamandla aphezulu okudonswa angu-40,000 PSI kanye namandla okucindezela angu-150,000 PSI. Ubulukhuni balo busukela ku-187 - 269 BHN. I-V-2 ifaneleka kakhulu ekusetshenzisweni kokugqoka okuqondile futhi inamandla aphezulu, ubulukhuni, ukumelana nokuguguleka kanye nempendulo yokwelapha ukushisa yensimbi empunga engaxutshwe. Isetshenziswa kabanzi ekusetshenzisweni kokuthwala kanye nokubopha embonini ye-hydraulics.
I-V-3 (65-45-12) Insimbi Ehlanganisiwe, i-ASTM A536:
Leli banga linamandla okudonswa angu-65,000 PSI, amandla okukhiqiza angu-45,000 PSI, kanye nobude obungu-12%. Ubulukhuni busukela ku-131-220 BHN. Isakhiwo salo esihle se-ferritic senza i-V-3 ibe yindlela elula kakhulu yokugaya amamaki amathathu ensimbi okwenza ibe ngelinye lamazinga aphezulu okugaya amamaki kwezinye izinto ze-ferrous; ikakhulukazi kuhlanganiswe nomthelela omuhle kakhulu, ukukhathala, ukuhanjiswa kukagesi kanye nezakhiwo zokungena kwamandla kagesi. I-Ductile Iron, ikakhulukazi amapayipi, isetshenziswa kakhulu emigqeni yamanzi kanye nendle. Le nsimbi ivame ukutholakala ezingxenyeni zezimoto kanye nezicelo zezimboni.
I-V-4 (80-55-06) Insimbi Ehlanganisiwe, i-ASTM A536:
Leli banga linamandla okudonswa angu-80,000 PSI, amandla okukhiqiza angu-55,000 PSI kanye nokunwetshwa okungu-6%. Lingamandla aphezulu kakhulu kulawa magremu amathathu, njenge-cast. Leli banga lingaphathwa ngokushisa libe namandla okudonswa angu-100,000 PSI. Linesilinganiso sokusebenza esiphansi ngo-10-15% kune-V-3 ngenxa yesakhiwo sayo se-pearlitic. Livame ukukhethwa kakhulu lapho kudingeka izinto zemvelo zensimbi.
Amapayipi e-DI angcono kunepayipi lensimbi / le-PVC / le-HDPE
• Amapayipi e-DI aphinde onge izindleko zokusebenza ngezindlela eziningana okuhlanganisa izindleko zokupompa, izindleko zokuthepha, kanye nomonakalo ongaba khona ovela kwezinye izakhiwo, okubangela ukwehluleka kanye nezindleko zokulungisa ngokujwayelekile.
• Izindleko zomjikelezo wokuphila kwamapayipi e-DI zingenye yezinzuzo zawo ezinkulu. Njengoba ihlala izizukulwane ngezizukulwane, iyonga ukuyisebenzisa, futhi ifakwa futhi isetshenziswe kalula nangendlela efanele, izindleko zayo zesikhathi eside noma zomjikelezo wokuphila ziphansi kalula kunanoma yiziphi ezinye izinto.
• Ipayipi lensimbi elithambile ngokwalo liyinto engasetshenziswa kabusha ngo-100%.
• Iqine ngokwanele ukumelana nezimo ezinzima kakhulu, kusukela ekusetshenzisweni komfutho ophezulu, kuya emithwalweni yomhlabathi esindayo kanye nemithwalo yezimoto, kuya ezimweni zenhlabathi ezingazinzile.
• Ukufakwa kulula futhi kuphephile kubasebenzi abangasika futhi bathinte i-Ductile Iron Pipe endaweni.
• Uhlobo lwensimbi lweDuctile Iron Pipe lusho ukuthi ipayipi lingatholakala kalula ngaphansi komhlaba ngezitholi zamapayipi ezivamile.
•Amapayipi e-DI anikeza amandla aphezulu okudonseka kunensimbi ethambile futhi agcina ukumelana kokugqwala okungokwemvelo kwensimbi ephonswe.
