ʻO ke koʻikoʻi o ka Sawn a Welded Pipe i Modern Infrastructure, Ma ka puʻuwai o Cangzhou, Hebei Province, e noho ana i kahi wili kila i lilo i pōhaku kihi o ka ʻoihana paipu kila mai kona hoʻokumu ʻia ʻana ma 1993. Ua uhi ka hui i 350,000 square meters, hoʻonani i nā waiwai āpau o 680 miliona RMB, a hoʻohana i nā limahana 680. Ma waena o kāna mau huahana he mau paipu ʻoki a welded, kahi mea koʻikoʻi o nā ʻenehana hou, ʻoi aku hoʻi i ka halihali wai honua.
MalaloPipa Welded Sawpono no ka lawe pono ʻana i ka wai ma nā wahi like ʻole. Hoʻokumu lākou i ka iwi kuamoʻo o kā mākou ʻoihana hou, e hōʻoia ana i ka wai maʻemaʻe e hiki i nā hale, nā ʻoihana, a me nā wahi mahiʻai. He mea koʻikoʻi ke koho ʻana i nā mea no kēia mau paipu, no ka mea, pono lākou e pale i nā koʻikoʻi o ka honua ma lalo o ka mālama ʻana i ko lākou kūpaʻa lōʻihi. ʻO kekahi o nā koho kaulana loa no kēia mau noi, ʻo ia ka paipu kila kalapona i wiliwili ʻia, kaulana no kona ikaika a paʻa.
ʻO S235 JR spiral steel pipe a me X70 SSAW (Spiral Submerged Arc Welded) laina paipu ʻelua mau huahana maʻamau i hoʻohana nui ʻia i nā ʻōnaehana paipu wai ma lalo o ka honua. Manaʻo nui ʻia ka paipu S235 JR no kāna mau waiwai mechanical maikaʻi, kūpono ia no nā ʻano noi like ʻole, me ka lawe ʻana i ka wai. ʻO kona hiki ke pale aku i ka deformation ma lalo o ke koʻikoʻi e hōʻoia i ka hoʻokō ʻana i nā koi o nā hale lalo.
I kēia lā, me ka wikiwiki o ke kaʻina hana kūlanakauhale, ua lilo kahi ʻōnaehana hoʻoili wai ma lalo o ka honua i mea nui e hōʻoia ai i ke ola o nā kānaka. Ma ke ʻano he ʻoihana alakaʻi i ka ʻoihana hana ʻenehana Pipe, ua hoʻolako kekahi hale kila ma Cangzhou City, Hebei Province, i nā paipu Saw Welded kiʻekiʻe no ka ʻoihana honua mai kona hoʻokumu ʻia ʻana i ka makahiki 1993. ʻO kāna S235 JR spiral steel pipes a me X70 submerged arc welded spiral pipes, me kā lākou ʻoihana ʻenehana maikaʻi loa, ua lilo i kumu waiwai no ka hana ʻana i lalo o ka honua.
1. ʻO ka ikaika kiʻekiʻe a me ka pale ʻana i ka corrosion e hōʻoia i ka palekana o ka lawe wai lōʻihi. S235 JR spiral paipu: He kūlana kūʻē maikaʻi loa ia i ka deformation koʻikoʻi a kūpono i nā kaiapuni honua paʻakikī, e hōʻoia ana i ka hana paʻa o ka pipeline. X70 SSAW paipu: Hana ʻia me ke kila ikaika kiʻekiʻe a me ka ʻenehana hoʻoheheʻe spiral kiʻekiʻe, ʻoi aku ka paʻakikī a me ka pale ʻana i ka corrosion, kūpono no ka lawe ʻana i ka wai lōʻihi a me nā kaiapuni paʻakikī.
2. Hoʻokumu ka ʻenehana holomua i hui pū ʻia me ka mana koʻikoʻi i kahi ʻōnaehana pipeline hoʻomau. Hoʻohana kēia hale hana i ka ʻenehana spiral submerged arc welding (SAW) e hoʻokō pono i ka hana ʻana o nā paipu ākea ākea ākea, me ka hoʻohana pono ʻana i ka hoʻohana pono ʻana i ka ikaika. Ma ka hui pū ʻana me kahi hui ʻoihana o 680 poʻe a me kahi laina hana hou i kūʻai ʻia he 680 miliona yuan, hōʻoia mākou i kēlā me kēia paipu kila e hoʻokō i nā kūlana honua, e kōkua ana i ka hoʻomohala ʻana i nā ʻōnaehana ʻōmaʻomaʻo. Me ka hoʻomaikaʻi ʻana i nā koi hoʻokele waiwai wai honua, e hoʻomau nā paipu ʻike-welded o Cangzhou Steel Plant e hāʻawi i nā hopena kiʻekiʻe a me nā kumu kūʻai haʻahaʻa no ka lawe ʻana i ka wai kūloko, mahiʻai a me ka ʻoihana, e hāpai ana i ke kūkulu ʻana i nā ʻōnaehana mālama mālama wai.
ʻO nā paipu sawn-a-welded i hana ʻia e Cangzhou Steel Mills he mea koʻikoʻi o nā ʻōnaehana wai honua. ʻO S235 JR a me X70 spiral submerged arc welded pipes, me ko lākou mau waiwai mechanical maikaʻi loa a me ke kū'ē i nā mea kaiapuni, he mea koʻikoʻi ia no ka hōʻoia ʻana i ka lawe ʻana i ka wai. Ke nānā aku nei i mua, e ulu mau ana ke koʻikoʻi o kēia mau huahana, e hōʻike ana i ka pono o ka ʻoihana paipu kila no ka hana kiʻekiʻe a me nā hopena hou.
