Centrifugal cast ductile hao paipu a me nā mea pono
Paipu hao ductile a me nā mea pono:
| 1 | Palapala | ISO9001/WRAS/SGS |
| 2 | Ka uhi ʻana o loko | a).ʻO ka lining mortar sima Portland |
| b).ʻO ka paʻa ʻana o ka sulphate kūpaʻa ʻia | ||
| c).Kiʻekiʻe-Alumikina kimeka paʻa | ||
| d).ʻO ka uhi epoxy i hoʻopaʻa ʻia | ||
| e).Pena epoxy wai | ||
| f).Pena kiʻi bitumen ʻeleʻele | ||
| 4 | Ka uhi waho | a).Zinc+bitumen(70microns) pena |
| b).ʻO ka uhi epoxy i hoʻopaʻa ʻia | ||
| c).Zinc-aluminum alloy+wai epoxy pena |
Hoʻohālikelike o nā waiwai:
| Helu 30 paipu hao | |||
| 'ikamu | DI paipu | Paipu GI | Paipu kila |
| Ka ikaika uʻi (N/mm2) | ≥ 420 | 150-260 | ≥ 400 |
| Ka ikaika kulou (N/mm2) | ≥ 590 | 200-360 | ≥ 400 |
| Elongation(%) | ≥ 10(DN40-1000) | 0 | ≥ 18 |
| Koefficient elasticity (N/mm2) | Ma kahi o 16×104 | Ma kahi o 11×104 | Ma kahi o 16×104 |
| 'Oolea(HB) | ≤ 230 | ≤ 230 | Ma kahi o 140 |
| ʻO ka pale ʻana ma hope o 90 mau lā (g/cm2) | 0.0090 | 0.0103 | 0.0273-0.0396 |
Centrifugally cast ductile hao paipu i hana 'ia mai spherical graphite hoolei hao e centrifugal spinning process.The paipu, e hiki ke lawe i na wai he nui e like me ka wai, aila a me ke kinoea, ua hoʻohana nui 'ia i loko o nā papahana pipeline no ka metallurgy, mine, mālama wai, petroleum. a me ka pono lawelawe aupuni o ke kaona.
1. Loaʻa i ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi e like me ke kila a ʻoi aku ka maikaʻi o ka corrosion ma mua o ke kila, hiki ke kōkua iā lākou e kū i ka haʻalulu i ʻike ʻia i ka wā o ka lawe ʻana, hoʻonohonoho, hoʻohana a hoʻohana.
2. ʻO ka paipu hao ductile ka mea kūpono no ka paipu hao hina hina a me ka paipu kila maʻamau.
3. Hoʻokumu ʻia nā paipu DI me ka pololei maikaʻi, ʻo ka mānoanoa o ka pā, ka pololei o ke ana kiʻekiʻe, ka hoʻopau ʻana o ka ʻili maʻemaʻe a me nā waiwai mechanical kupaianaha, a me ka paʻa paʻa ʻana o ka ʻili o loko & waho.
4.Flexible Push-in ami a me ka hao gasket ua hoʻohana 'ia ka hopena i ka hoʻokomo pono o pipelines.
5. ʻOi aku ka maikaʻi o ka koho ʻana, no ka mea, hana ʻia lākou mai nā mea hana hou ʻia, kahi hiʻohiʻona hiʻohiʻona mai kahi hiʻohiʻona kaiapuni.
ʻOi aku ka nui o nā anawaena 6.Inside ma mua o ka hapa nui, e hoʻonui ana i ke kahe, e hoʻemi ana i ka hoʻohana ʻana i ka ikehu a me nā kumukūʻai pumping i ka manawa
7. He kiʻekiʻe ka pohā ikaika o lākou, i kūpono no nā noi kiʻekiʻe.
