Huahana Huahana
Paipu kila hao nodulars he mau paipu hao ductile, nona ke ano o ka hao a me na waiwai o ke kila, nolaila ko lakou inoa. ʻO ka graphite i loko o nā paipu hao ductile aia ma ke ʻano spherical, me ka nui maʻamau o 6-7 mau māka. Ma keʻano o ka maikaʻi, pono e hoʻomaluʻia ka pae spheroidization o nā paipu hao hao ma nā pae 1-3, me ka nui o ka spheroidization o ≥ 80%. No laila, ua hoʻomaikaʻi ʻia nā ʻano mechanical o ka mea ponoʻī, nona ke ʻano o ka hao a me nā waiwai o ke kila. Ma hope o ka annealing, ʻo ka microstructure o nā paipu hao ductile he ferrite me kahi liʻiliʻi o ka pearlite, nona nā waiwai mechanical maikaʻi, no laila ua kapa ʻia ʻo ia hoʻolei.paipu kila hao.

| 10. MOQ | 1 tona |
| 11. Hāʻawi: | Nā pūʻolo, i ka nui, |
1. Ke kū'ē kū'ē i loko:ʻO ka paipu hao Ductile ka ikaika o ke kila me ka paʻakikī o ka haoʻo ia ka koho palekana. Hoʻohana ʻia ke kaomi hana kiʻekiʻe, a ʻoi aku ka nui o ke kaomi ʻana i ʻekolu manawa o ke kaomi hana.
2.External Pressure Resistance: ʻO ke kūpaʻa kiʻekiʻe o ke kaomi ʻana, ʻo ia ka mea e pono ai ka liʻiliʻi o nā moena kūikawā a i ʻole ka uhi ʻana, e ʻoi aku ka maʻalahi o kāu hoʻonohonoho ʻana.
3. Inner Anti-Corrosion Layer: Hoʻopili ʻia nā paipu me ka mīkini sima e like me ISO 4179 no nā noi wai inu. Hāʻawi kēia kaʻina hana i kahi lining maʻemaʻe a paʻakikī e pale ai i ka wai inu a ʻaʻole paheʻe a ʻōpala.
4.Paʻa Paʻa: Zinc spraying (≥130 g/m², ISO 8179) a me ka chlorinated Resin pena e hiki ai ke pale maikaʻi i ka ʻino. Hiki ke hāʻawi ʻia nā ʻāpana zinc mānoanoa a i ʻole ka zinc-aluminium coatings e like me nā kikoʻī o nā mea kūʻai aku.
Nā hiʻohiʻona
Paipu hao ductilehe ʻano paipu hao. Hana ʻia nā paipu hao ductile ma kahi pae 1-3 o ka spheroidization (Spheroidizationrate> 80%) e hoʻomaikaʻi i nā waiwai mechanical ma o ka hoʻohana ʻana i ka ikaika o ke kila a me ka paʻakikī o ka hao. ʻO ka paipu annealed he hale ferrite me kahi liʻiliʻi o ka pearlite, a he kūpaʻa maikaʻi ka corrosion, ductility, sealing performance a maʻalahi no ka hoʻokomo. ʻIke lākou i ka hoʻohana nui ʻana i ka lako wai, ka lawe ʻana i ke kinoea, a me ka lawe ʻana i ka aila ma ke kūlanakauhale a me ka ʻoihana.
Hoʻopuni ʻia ka graphite spherical e kahi matrix o ka ferrite a me ka pearlite. ʻO ka nui o ka pearlite i ka ferrite e pili ana i ka nui o ka paipu a me kāna mau elongation koi: no ka hapa nui, nā paipu liʻiliʻi liʻiliʻi he pearlite ≤20% a me nā paipu nui-diameter ≈25%.
Palapala noi
ʻO nā paipu hao ductile i ka nui mai 80 a 1600 mm pili i ka wai inu (BS EN 545) a me nā ʻōnaehana wai (BS EN 598). Hoʻohui maʻalahi lākou, hoʻokomo i kēlā me kēia manawa, maʻamau me ka ʻole o ka backfill kūikawā, a hāʻawi i kahi kumu kiʻekiʻe o ka palekana me ka hiki ke kū i ka neʻe ʻana o ka honua, e hoʻolako pono iā lākou no ka hoʻohana ʻana i nā noi pipeline.
