Nūhou - Paipu Hao Ductile: ʻO ke kumu nui o nā ʻōnaehana paipu hou

Paipu Hao Ductile, hana ʻia me ka hao hoʻoheheʻe e like me ke kumu kumu. Ma mua o ka ninini ʻana, hoʻohui ʻia ka magnesium a i ʻole ka honua lāʻau magnesium a me nā mea hana spheroidizing ʻē aʻe i ka hao i hoʻoheheʻe ʻia e spheroidize i ka graphite, a laila hana ʻia ka paipu ma o nā kaʻina hana paʻakikī. ʻO ka ʻokoʻa o ka hao ductile ʻo ia ka hapa nui a i ʻole nā mea āpau o ka graphite precipitated ma ke ʻano spherical, a ʻo kēia ʻano hoʻolālā e hoʻomaikaʻi nui i ka hana o ka mea. Ma hope o ka hoʻopili ʻana, ʻo ke ʻano metallographic oPaipu Hao ʻEleʻeleʻO ka ferrite me kahi mea liʻiliʻi o ka pearlite, a ua maikaʻi nā waiwai mechanical. ʻ

ʻO ka moʻolelo hoʻomohala oPaipu Hao Ductilepiha i nā mea hou a me nā holomua. I ka hopena o 1980s a me ka 1990s mua, e kū ana i ka blockade o nā haole centrifugal ductile iron pipe production technology a me nā kūlana mana patent paʻakikī, ʻo ka 2672nd Factory of the Chinese People's Liberation Army (ka mea mua o Xinxing Casting Pipe) me ka wiwo ʻole i ka hana o ka noiʻi kūʻokoʻa a me ka hoʻomohala ʻana. I ka makahiki 1993, ua holo pono ka paipu hao ductile centrifugal mua ma Kina mai ka laina hana, e hōʻailona ana ua hoʻokō koʻu ʻāina i kahi lele mai ka ʻohi ʻana ma kēia kahua, a ʻewalu mau makahiki wale nō e hoʻopau ai i ke kaʻina hana hoʻomohala 40 makahiki o nā ʻāina Komohana. I kēia lā, ua hoʻomohala ʻo Xinxing Casting Pipe i ka honua nui a ikaika loa ka centrifugal ductile hao paipu, a ua komo pū i ka hoʻokumu ʻana i nā kūlana hoʻolei honua, e hoʻoikaika mau ana i ka hoʻomohala ʻana i ka ʻoihana ductile hao.

He ʻokoʻa nā ʻano hana o nā paipu hao Ductile

1. Ka ikaika kiʻekiʻe a me ka paʻakikī maikaʻi: He ikaika kiʻekiʻe ka ikaika o nā paipu hao ductile, a ʻoi aku ka maikaʻi o ko lākou ikaika i ka hoʻohālikelike ʻia me nā paipu hao maʻamau. No ka mea ua puʻunaue ʻia ka graphite ma ke ʻano spherical, ua hoʻemi ʻia ka hopena o ka māhele ʻana i ka matrix, me ka liʻiliʻi o ka haʻihaʻi ʻana o ka paipu i ka wā e hoʻopiʻi ʻia ai ka hopena a me ka hopena. I ka manawa like, loaʻa iā ia ka paʻakikī maikaʻi, me ka elongation maʻamau ma mua o 10%, a hiki ke hoʻololi i ka hoʻohaʻahaʻa ʻana o ka lepo, ka neʻe ʻana o ka lepo a me nā kūlana ʻē aʻe i kekahi ʻano. ʻAʻole maʻalahi ka hōʻino ʻia e ka deformation, kahi e hoʻomaikaʻi ai i ka hilinaʻi o ka hana ʻoihana paipu

2. Paʻa Paʻa Paʻa: Ma o nā ʻano hana lapaʻau anti-corrosion like ʻole, e like me ka uhi ʻana i ka pena asphalt, ka mortar ciment lining, epoxy coal tar coating, epoxy ceramic lining, aluminate cement coating, sulfate cement coating a me ka polyurethane coating, hiki i nā paipu hao ductile ke pale pono i ka corrosion mai nā media like ʻole. Inā hoʻohana ʻia no ka lawe ʻana i ke kinoea, ka wai paila, a i ʻole no ka hoʻokuʻu ʻana i ka wai, hiki iā ia ke mālama i ka hana paʻa i nā ʻano paʻakikī like ʻole, hoʻonui i ke ola lawelawe o ka pipeline, a hoʻemi i nā kumukūʻai mālama. ʻ
3. Sila maikai: Hoʻohana ka waha paipu i kahi pilina maʻalahi, hiki ke hoʻololi i ka neʻe ʻana a me ka deformation i loko o kekahi ʻano, hana i kahi hopena sila maikaʻi ma ka ʻāpana pili paipu, a pale pono i ka leakage wai. I ka manawa like, ʻo ke kaʻina hana hana kiʻekiʻe o ka paipu ponoʻī e hōʻoia i ka pololei o ke kumu, hoʻomaikaʻi hou i ka hana hoʻopaʻa ʻana, a hōʻoia i ka hana palekana o ka ʻōnaehana pipeline. ʻ
4. Hoʻokomo maʻalahi: Ke hoʻohālikelike ʻia me kekahi mau paipu ʻē aʻe, ʻoi aku ka maʻalahi o ke kaumaha o nā paipu hao ductile, a maʻalahi ke kaʻina hana. ʻO kāna kikowaena maʻalahi e hoʻomaʻamaʻa i nā limahana hana e hoʻokō i ka hana pili, e hōʻemi ana i ka manawa hoʻokomo a me ka ikaika o ka hana. Ma ke kahua kūkulu, hiki ke hoʻopau koke ʻia ka hoʻokomo ʻana i nā pipeline me ka ʻole o nā mea paʻakikī a me nā ʻenehana loea, kahi e hoʻopōkole nui ai i ka pōʻai o ka papahana a hoʻomaikaʻi i ka hana hana. ʻ
5. Hana Antifreeze maikaʻi: Ma nā wahi anu, he mea koʻikoʻi ka hana antifreeze o nā pipeline. Loaʻa i nā paipu hao ductile kekahi degere o ka antifreeze. ʻOiai ʻaʻole ia he kaiapuni koʻikoʻi loa, ʻaʻole loa e loaʻa nā māwae a me nā pohā. Hoʻohana nui ʻia kēia i ka lako wai, ka hoʻomehana a me nā ʻōnaehana pipeline ʻē aʻe ma nā ʻāina anuanu ʻākau, e hāʻawi ana i nā lawelawe hilinaʻi no nā kamaʻāina a me nā ʻoihana. ʻ

Paipu wai hao haoua lilo i mea waiwai nui a koʻikoʻi i ke kūkulu ʻana i nā ʻenehana hou me kā lākou mau hiʻohiʻona maikaʻi loa. Mai ka hoʻolako ʻana i ka wai o ke kūlanakauhale a me ka hoʻoheheʻe ʻana i ke kinoea, mai ka hana ʻenehana a i nā papahana mālama wai, hana nui nā paipu hao ductile i nā ʻano hana like ʻole a ua hāʻawi i nā mea nui i ka hōʻoia ʻana i ka maikaʻi o ke ola o ka poʻe a me ka hoʻonui ʻana i ka hoʻokele waiwai. Me ka holomua mau a me ka hana hou o ka ʻenehana, e hoʻomau ka hana o nā paipu hao ductile, a e hoʻonui hou ʻia ka laulā o ka noi. E hoʻomau lākou i ka ʻālohilohi i ke kūkulu ʻana i nā ʻoihana e hiki mai ana. ʻ
