Centrifugal cast ductile iron chitoliro ndi zovekera
Chitoliro chachitsulo cha ductile & zopangira:
| 1 | Satifiketi | ISO9001/WRAS/SGS |
| 2 | Kupaka mkati | a).Mzere wa simenti wa Portland |
| b).Mzere wa matope a simenti osamva sulphate | ||
| c).High-Aluminiyamu simenti matope mzere | ||
| d).Fusion yolumikizidwa ndi epoxy zokutira | ||
| e).Kupenta kwamadzi epoxy | ||
| f).Chojambula chakuda cha phula | ||
| 4 | Chophimba chakunja | a).Kupenta kwa Zinc+bitumen(70microns). |
| b).Fusion yolumikizidwa ndi epoxy zokutira | ||
| c).Zinc-aluminiyamu alloy + utoto wa epoxy wamadzimadzi |
Kuyerekeza kwa katundu:
| Gulu la ductile iron pipe 30 | |||
| Kanthu | DI pipe | Mtengo wa GI | Chitoliro chachitsulo |
| Kulimba kwamphamvu (N/mm2) | ≥ 420 | 150-260 | ≥ 400 |
| Mphamvu yopindika (N/mm2) | ≥ 590 | 200-360 | ≥ 400 |
| Kutalikira (%) | ≥ 10(DN40-1000) | 0 | ≥ 18 |
| Kuthamanga kwapakati (N/mm2) | Pafupifupi 16 × 104 | Pafupifupi 11 × 104 | Pafupifupi 16 × 104 |
| Kulimba (HB) | ≤230 | ≤230 | Pafupifupi.140 |
| Kukana dzimbiri pambuyo pa masiku 90 (g/cm2) | 0.0090 | 0.0103 | 0.0273-0.0396 |
Centrifugally kuponyedwa ductile chitsulo chitoliro anapangidwa kuchokera ozungulira graphite kuponyedwa chitsulo ndi centrifugal kupota process.The mapaipi, amene angathe kusonyeza TV madzimadzi ambiri monga madzi, mafuta ndi gasi, chimagwiritsidwa ntchito zosiyanasiyana mapaipi ntchito zitsulo, mgodi, kusungira madzi, mafuta. ndi zothandiza anthu m'tauni.
1.Kukhala ndi mphamvu zambiri, kulimba kwabwino ngati chitsulo komanso kukana kwa dzimbiri kuposa chitsulo, zomwe zingawathandize kulimbana ndi mantha omwe amakumana nawo panthawi yoyendetsa, kuika, kusamalira ndi kugwiritsa ntchito.
2.Chitoliro chachitsulo cha ductile ndicho choloweza m'malo mwa chitoliro chachitsulo cha imvi ndi chitoliro chachitsulo wamba.
3.Mapaipi a DI amapangidwa ndi kuwongoka kwabwino, ngakhale makulidwe a khoma, kulondola kwapamwamba kwambiri, kumaliza kosalala komanso mawonekedwe odabwitsa amakina, kuphatikiza ndikumata mwamphamvu mkati & kunja.
4.Flexible Push-in joint ndi rabara gasket amagwiritsidwa ntchito zomwe zimapangitsa kuti mapaipi azikhala osavuta.
5.Iwo ndi chisankho chokhazikika, chifukwa nthawi zambiri amapangidwa kuchokera kuzinthu zobwezerezedwanso, zomwe ndizomwe zimawonekera kuchokera ku chilengedwe.
6.Madiameters amkati ndi aakulu kuposa ambiri, kuwonjezeka kwa kuyenda, komwe kumachepetsa kugwiritsa ntchito mphamvu ndi kupopera ndalama pakapita nthawi
7.Iwo ali ndi mphamvu yophulika kwambiri, yomwe ili yoyenera kugwiritsira ntchito kuthamanga kwambiri.
