DN600 ductile hao Manhole uhi

ʻO ka pōʻaiuhi manhole he ʻano hao graphite spheroidal. Hoʻopili ʻia ka spheroidal graphite cast spheroidal graphite e hoʻomaikaʻi maikaʻi i nā waiwai mechanical o ka hao, ʻoi aku ka paʻakikī a me ka paʻakikī, e loaʻa ai ka ikaika kiʻekiʻe ma mua o ke kila kalapona. ʻO ka hao ductile he ʻano mea hao hao ikaika i kūkulu ʻia i nā makahiki 1950. ʻO kāna hana holoʻokoʻa kokoke i ke kila. Hoʻokumu ʻia ia i kāna hana maikaʻi loa a ua hoʻohana maikaʻi ʻia no ka hoʻolei ʻana i kekahi mau ikaika paʻakikī, ikaika, paʻakikī a me ke kūpaʻa ʻana. Nā ʻāpana me nā koi kiʻekiʻe. Ua ulu wikiwiki ka hao i hoʻohana nui ʻia ma hope o ka hao hina hina. ʻO ka mea i kapa ʻia ʻo "iron-based steel" e pili ana i ka hao ductile.

(1) Puuwai paipu mana uila; Leka, kelepona, paipu paipu;
(2) Puuwai kukui alanui, punawai hoomalu ahi, punawai valve a pau;
(3) Ka wai o ke kūlanakauhale, ka lua wai paipu; Hāʻawi ʻia ka wela, punawai kinoea;
(4) Pāhana anti-corrosion, auwai hāmama; Hiki ke hana ʻia e like me nā koi o nā mea kūʻai aku.

1. E kūʻē i ka ʻaihue - Composite Manhole Cover me shockproof rubber sealing he non-metallic, non-conductive a non-sparking, ʻaʻohe waiwai o ka hana hou ʻana, hoʻopau loa i nā pilikia ʻaihue.

2. Hiki ke hoʻouka nui — ʻO kona mau mea nui he fiberglass a me ka resin unsaturated. ʻO ka mana oad he A15, B125, C250, D400, E600.

3. Hoʻolālā manuahi-e like me ke kala, Logo, Panel, Load a me Dimension hiki ke hoʻolālā ʻia e like me nā koi o ka mea kūʻai aku.

4. Ola lōʻihi —ʻO ke ola liʻiliʻi he 30 makahiki me ka ʻole o ka mālama.

5. Hoʻopaʻa maikaʻi ʻia - Hiki ke hoʻokomo ʻia me ka hermetically, a pale pono i nā kinoea ʻawaʻawa e kahe ana mai loko mai o ka lua. ʻaʻohe leo pollution a i ʻole rebound.

6. ʻO ka ʻaʻahu maikaʻi a me ka pale ʻana i ka corrosion — ʻAʻole loa ia e ʻōpala no ka mea he maikaʻi kona ʻaʻahu a me ka pale ʻana.

7. Kūleʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa —He insulator maikaʻi loa (mai-40°C~200°C)

8. ʻOi aku ka māmā a me ke kumu kūʻai hoʻokūkū— ʻoi aku ka māmā o ke kaumaha o ka uhi manhole composite, ʻoi aku ka māmā o ka uhi manhole SMC. ʻOi aku ka maʻalahi o ka uhi manhole composite no ka lawe ʻana, hoʻokomo a hoʻoponopono.
