Uhlolojikelele lwe-Ductile Iron Pipe
Amapayipi e-Ductile Iron amapayipi enziwe nge-ductile iron.I-Ductile iron iyi-spheroidized graphite cast iron.Izinga eliphezulu lokwethenjwa kwe-iron ductile ngokuyinhloko kungenxa yamandla ayo aphezulu, ukuqina, kanye nomthelela kanye nokungagqwali.Amapayipi ensimbi anezimbotshana ajwayele ukusetshenziselwa ukusatshalaliswa kwamanzi aphuzwayo kanye nokumpompa ama-slurries, indle kanye namakhemikhali okucubungula.Lawa mapayipi ensimbi awukuthuthukiswa okuqondile kwamapayipi ensimbi angaphambili acishe awashintsha.Izinga eliphezulu lokwethenjelwa kwamapayipi e-iron ductile kungenxa yezindawo zayo eziphakeme ezihlukahlukene.Lawa mapayipi yiwona afunwa kakhulu amapayipi ezicelo eziningi.

Amabanga Amathathu Abalulekile Epayipi Lensimbi Esakhiwe
I-V-2 (isigaba 40) I-Grey Iron, i-V-3 (65-45-12) I-Ductile Iron, ne-V-4 (80-55-06) I-Ductile Iron.Banikeza amandla amahle kakhulu okucindezela kanye nekhono eliphezulu lokudambisa ukudlidliza.
I-V-2 (ikilasi 40) I-Grey Iron, i-ASTM B48:
Leli banga linamandla amakhulu okunyakazisa angu-40,000 PSI namandla okucindezela angu-150,000 PSI.Ubulukhuni bayo busukela ku-187 - 269 BHN.I-V-2 ifaneleka kahle ekugqokeni okuqondile futhi inamandla aphakeme kakhulu, ubulukhuni, ukumelana nokuguga kanye nempendulo yokwelapha ukushisa kwensimbi empunga engaxutshiwe.Isetshenziswa kabanzi ekukhiqizeni nasekusetshenzisweni kwe-bushing embonini ye-hydraulics.
I-V-3 (65-45-12) I-Ductile Iron, i-ASTM A536:
Leli banga linamandla aqinile we-65,000 PSI, amandla esivuno angama-45,000 PSI, ane-elongation engu-12%.Ubunzima busukela ku-131-220 BHN.Ukwakheka kwayo okuhle kwe-ferritic kwenza i-V-3 ibe mashini elula kakhulu emazingeni amathathu ensimbi okuyenza ibe ngelinye lamabanga aphezulu alinganiswe ngokusebenza kwezinye izinto ezinsimbi;ikakhulukazi kuhlanganiswe nomthelela omuhle, ukukhathala, ukuqhutshwa kukagesi kanye nezakhiwo ze-magnetic permeability.I-Ductile Iron, ikakhulukazi amapayipi, isetshenziselwa ikakhulukazi izintambo zamanzi nezokukhucululwa kwendle.Le nsimbi iphinde itholakale ezingxenyeni zezimoto nasezinhlelweni zezimboni.
I-V-4 (80-55-06) I-Ductile Iron, i-ASTM A536:
Leli banga linamandla aqinile we-80,000 PSI, amandla esivuno angama-55,000 PSI kanye nobude obungu-6%.Ingamandla aphakeme kunawo wonke amabanga amathathu, njengabalingisi.Leli banga lingaphathwa ngokushisa libe namandla e-PSI angu-100,000.Inesilinganiso esiphansi esingu-10-15% sokusebenza kwemishini kune-V-3 ngenxa yesakhiwo sayo se-pearlitic.Ivame ukukhethwa lapho insimbi yensimbi idingeka.
Amapayipi e-DI angcono kunensimbi / PVC / HDPE amapayipi
• I-DI Pipes iphinde yonga izindleko zokusebenza ngezindlela eziningana ezihlanganisa izindleko zokumpompa, izindleko zokuthepha, kanye nomonakalo ongaba khona kusukela kokunye ukwakhiwa, okubangela ukwehluleka kanye nezindleko zokukhanda ngokujwayelekile.
• Izindleko ze-Lifecycle ze-DI Pipes zingenye yezinzuzo zayo ezinkulu.Njengoba ihlala izizukulwane ngezizukulwane, iyonga ukusebenza, futhi ifakwe kalula futhi isebenza kahle, izindleko zayo zesikhathi eside noma zomjikelezo wokuphila ziphansi kalula kunanoma iyiphi enye impahla.
• Ipayipi le-iron elenziwe ngensimbi ngokwalo liyi-100% yezinto ezigaywa kabusha.
• Iqine ngokwanele ukumelana nezimo ezinzima kakhulu, kusukela ekufakweni kwengcindezi ephezulu, emhlabeni osindayo kanye nemithwalo yezimoto, kuya ezimweni zenhlabathi ezingazinzile.
• Ukufakwa kulula futhi kuphephile kubasebenzi abakwazi ukusika futhi bacofe Ipayipi Lensimbi Elihlanganisiwe esizeni.
• Ubume bensimbi be-Ductile Iron Pipe busho ukuthi ipayipi lingatholakala kalula ngaphansi komhlaba nezikhombi zamapayipi ezivamile.
•Amapayipi e-DI anikeza amandla aqinile aphezulu kunensimbi ethambile futhi agcina ukumelana nokugqwala okungokwemvelo kwensimbi ekhonjiwe.
