Chidule cha Ductile Iron Pipe
Mapaipi achitsulo cha Ductile ndi mapaipi opangidwa ndi chitsulo chosungunuka. Chitsulo cha ductile ndi chitsulo chosungunuka cha graphite. Kudalirika kwakukulu kwa chitsulo chosungunuka kumachitika makamaka chifukwa cha mphamvu yake yayikulu, kulimba, komanso kukana dzimbiri. Mapaipi achitsulo cha Ductile nthawi zambiri amagwiritsidwa ntchito pogawa madzi akumwa komanso kupopera matope, zimbudzi ndi mankhwala opangira mankhwala. Mapaipi achitsulo awa ndi opangidwa mwachindunji ndi mapaipi akale achitsulo omwe tsopano atsala pang'ono kusintha. Kudalirika kwakukulu kwa mapaipi achitsulo cha ductile ndi chifukwa cha makhalidwe ake osiyanasiyana apamwamba. Mapaipi awa ndi omwe amafunidwa kwambiri pa ntchito zingapo.

Magulu Atatu Aakulu a Chitoliro Chopangidwa ndi Iron
V-2 (kalasi 40) Iron Yotuwa, V-3 (65-45-12) Iron Yotuwa, ndi V-4 (80-55-06) Iron Yotuwa. Amapereka mphamvu yabwino kwambiri yokanikiza komanso mphamvu yayikulu yochepetsera kugwedezeka.
V-2 (kalasi 40) Iron Yotuwa, ASTM B48:
Mtundu uwu uli ndi mphamvu yokoka ya 40,000 PSI ndi mphamvu yokoka ya 150,000 PSI. Kuuma kwake kumayambira pa 187 mpaka 269 BHN. V-2 ndi yoyenera kugwiritsidwa ntchito molunjika ndipo ili ndi mphamvu zambiri, kuuma, kukana kusweka komanso kuyamwa kutentha kwa chitsulo chotuwa chosagwiritsidwa ntchito. Imagwiritsidwa ntchito kwambiri popangira ma bearing ndi bushing mumakampani opanga ma hydraulic.
V-3 (65-45-12) Chitsulo Chodulira, ASTM A536:
Mtundu uwu uli ndi mphamvu yokoka ya 65,000 PSI, mphamvu yotulutsa ya 45,000 PSI, yokhala ndi kutalika kwa 12%. Kuuma kwake kumayambira pa 131-220 BHN. Kapangidwe kake ka ferritic kamapangitsa V-3 kukhala njira yosavuta kwambiri yopangira zitsulo zitatu zomwe zimapangitsa kuti ikhale imodzi mwa njira zabwino kwambiri zogwirira ntchito poyerekeza ndi zipangizo zina zachitsulo; makamaka kuphatikiza ndi mphamvu yabwino, kutopa, kuyendetsa magetsi ndi mphamvu ya maginito yolowera. Ductile Iron, makamaka mapaipi, imagwiritsidwa ntchito makamaka pamadzi ndi zimbudzi. Chitsulochi chimapezekanso m'zigawo zamagalimoto ndi mafakitale.
V-4 (80-55-06) Chitsulo Chodulira, ASTM A536:
Mtundu uwu uli ndi mphamvu yokoka ya 80,000 PSI, mphamvu yotulutsa ya 55,000 PSI ndi kutalika kwa 6%. Ndi mphamvu yapamwamba kwambiri pa mitundu itatuyi, monga momwe imagwiritsidwira ntchito. Mtundu uwu ukhoza kutenthedwa ndi kutentha kwa 100,000 PSI mphamvu yokoka. Uli ndi mphamvu yotsika ya 10-15% kuposa V-3 chifukwa cha kapangidwe kake ka pearlitic. Nthawi zambiri umasankhidwa pamene pakufunika zida zachitsulo.
Mapaipi a DI ndi abwino kuposa mapaipi achitsulo / PVC / HDPE
• Mapaipi a DI amasunganso ndalama zogwirira ntchito m'njira zingapo kuphatikizapo ndalama zopopera, ndalama zopopera, komanso kuwonongeka komwe kungachitike chifukwa cha zomangamanga zina, zomwe zimapangitsa kuti pakhale kulephera komanso ndalama zokonzera zonse.
• Mtengo wa moyo wonse wa Mapaipi a DI ndi umodzi mwa ubwino wake waukulu. Popeza umakhalapo kwa mibadwomibadwo, ndi wotsika mtengo kugwiritsa ntchito, komanso umayikidwa mosavuta komanso moyenera, mtengo wake wautali kapena moyo wonse ndi wotsika mosavuta kuposa zipangizo zina zilizonse.
• Chitoliro chachitsulo chopangidwa ndi ductile chokha ndi chinthu chobwezerezedwanso 100%.
• Ndi yolimba mokwanira kuti ipirire mikhalidwe yovuta kwambiri, kuyambira kugwiritsidwa ntchito ndi mphamvu yamagetsi, mpaka katundu wolemera wa nthaka ndi magalimoto, mpaka mikhalidwe yosakhazikika ya nthaka.
• Kuyika n'kosavuta komanso kotetezeka kwa ogwira ntchito omwe amatha kudula ndikupopa Ductile Iron Pipe pamalopo.
• Kapangidwe ka chitsulo ka Ductile Iron Pipe kumatanthauza kuti chitolirocho chikhoza kupezeka mosavuta pansi pa nthaka pogwiritsa ntchito malo opezera chitoliro wamba.
•Mapaipi a DI amapereka mphamvu yokoka kwambiri kuposa chitsulo chofewa ndipo amasunga kukana dzimbiri kwa chitsulo chopangidwa ndi chitsulo.
