Nā ʻano o ka uhi ʻana o ka hao Ductile Manhole

1. Ka kūpaʻa maikaʻi:He maikaʻi loa ka waiwai hopena o ke kila kalapona waena, ʻoi aku ma mua o 10 mau manawa o ka hao hina.

2. Ke kūpaʻa ikaika i ka pala: I ka hoʻāʻo ʻana i ka pala wai, ʻo ka nui o ka pala i loko o 90 mau lā he 1/40 wale nō o nā paipu kila a me 1/10 o nā paipu hao hina. ʻOi aku ka pālua o ke ola lawelawe o nā paipu hao hina a ʻelima manawa o nā paipu kila maʻamau.

3. Maikaʻi ka plasticity: Elongation ≥ 7/100, like me ke kila kalapona kiʻekiʻe, ʻoiai ʻo ka elongation o ka mea hao hina hina he zero.

4. Ikaika kiʻekiʻe: ʻO ka ikaika tensile ó b he ≥ 420MPa, a ʻo ka ikaika huahua he ≥ 300MPa, ʻo ia ka mea like me ke kila kalapona haʻahaʻa a ʻekolu manawa o ka mea hao hina.
Ka ikaika o hao ductile ua like ia me ke kila i hoʻolei ʻia. He kiʻekiʻe ka ikaika o ka hao ductile ma ka liʻiliʻi he 40k, ʻoiai he 36k wale nō ka ikaika o ke kila i hoʻolei ʻia. I ka hapa nui o nā noi kūlanakauhale, e like me ka wai, ka wai paʻakai, ka mahu, a me nā mea ʻē aʻe, ʻoi aku ka pale ʻana i ka pala a me ke kūpaʻa ʻana i ka oxidation o ka hao ductile ma mua o ke kila i hoʻolei ʻia. ʻO nā wahi noi nui: nā alanui kūlanakauhale, nā alaloa nui, ke kamaʻilio ʻana, ka uila, ka mālama wai, nā kaiāulu, nā kula, a me nā paka like ʻole.

5. Hana maikaʻi aʻe no ka pale ʻaihue a me ka palekana:
Ua like ka ikaika tensile a me ke kūpaʻa kaomi o nā tweezers uhi lua hao ductile me ke kila, no laila ua kapa ʻia lākou he kila hoʻolei. Ke hoʻohālikelike ʻia me ka hao hoʻolei hina kuʻuna, ua hoʻomaikaʻi nui ʻia kona wikiwiki elongation, maikaʻi kona paʻakikī, a ʻaʻole maʻalahi ka haki ʻana. ʻOi aku ka maikaʻi o ka hana anti-theft ma mua o ka maʻamau. nā uhi manhole hao i hoʻolei ʻia, a ʻoi aku ka maikaʻi o kāna hana holoʻokoʻa ma mua o ka maʻamau Lua hao i hoʻolei ʻia nā uhi.
