Ua hoʻohana ʻia nā ʻano hana hana paipu kila ʻelua i hoʻohana ʻia no nā makahiki he mau makahiki; i ka wā lōʻihi, ua holomua nā ʻano hana i hana ʻia i kēlā me kēia. No laila ʻoi aku ka maikaʻi?
1. Manufacturing welded paipu
Hoʻomaka ka paipu welded ma ke ʻano he lipine kila lōʻihi i wili ʻia i kapa ʻia he skelp. Hoʻokiʻoki ʻia ka skelp i ka lōʻihi i makemake ʻia, e loaʻa ana i kahi ʻāpana ʻāpana ʻehā. E lilo ana ka laula o na wēlau pōkole o ka paipu i ka pōʻai waho o ka paipu, he waiwai hiki ke hoʻohana no ka helu ʻana i kona anawaena o waho.
Hānai ʻia nā ʻaoʻao ʻāpana ʻehā ma o ka mīkini ʻōwili e ʻōwili i nā ʻaoʻao lōʻihi i luna i kekahi i kekahi, e hana ana i ka cylinder. Ma ke kaʻina hana ERW, ua hoʻoheheʻe ʻia ke au uila kiʻekiʻe ma waena o nā ʻaoʻao, e hoʻoheheʻe ai lākou a hui pū.
ʻO kahi pōmaikaʻi o ka paipu ERW, ʻaʻole i hoʻohana ʻia nā metala fusion a ʻaʻole hiki ke ʻike ʻia a ʻike ʻia ke kaʻina weld. Kū'ē kēlā i ka welding arc submerged arc (DSAW), e waiho ana ma hope o kahi wili weld maopopo pono e hoʻopau ʻia ma muli o ke noi.
Ua hoʻomaikaʻi ʻia nā ʻenehana hana paipu weld i nā makahiki. Malia paha ʻo ka holomua nui loa ʻo ia ka hoʻololi ʻana i nā au uila kiʻekiʻe no ka wili. Ma mua o nā makahiki 1970, ua hoʻohana ʻia ke ʻano haʻahaʻa haʻahaʻa. ʻOi aku ka maʻalahi o nā hili weld i hana ʻia mai ka ERW alapine haʻahaʻa i ka ʻinoʻino a me ka hiki ʻole o ke hili.
ʻO ka hapa nui o nā ʻano paipu welded pono e mālama i ka wela ma hope o ka hana ʻana.
2. Ka hana ʻana i ka paipu ʻole
Hoʻomaka ka paipu ʻole ma ke ʻano he hunk cylindrical paʻa o ke kila i kapa ʻia he billet. ʻOiai e wela ana, ua hou ʻia nā billet ma ke kikowaena me kahi mandrel. ʻO ka hana aʻe, ʻo ia ka ʻōwili ʻana a me ka hohola ʻana i ka hollow billet. ʻOlokaʻa pololei ʻia ka billet a kau ʻia a hiki i ka loaʻa ʻana o ka lōʻihi, ke anawaena a me ka mānoanoa o ka paia e like me ka mea i kuhikuhi ʻia e ka mea kūʻai aku.
ʻO kekahi mau ʻano paipu maʻemaʻe e paʻakikī i ka wā i hana ʻia ai, no laila ʻaʻole koi ʻia ka mālama wela ma hope o ka hana ʻana. Pono nā mea ʻē aʻe i ka mālama wela. E noʻonoʻo i ka kikoʻī o ke ʻano paipu seamless āu e noʻonoʻo nei e aʻo inā pono ia i ka mālama wela.
3. Nā hiʻohiʻona mōʻaukala a me ka hoʻohana ʻana i nā hihia no ka paipu kila welded vs
Aia ka ERW a me ka paipu kila ʻole ma ke ʻano he mau koho ʻē aʻe i kēia lā ma muli o ka manaʻo o ka mōʻaukala.
ʻO ka maʻamau, ʻoi aku ka nāwaliwali o ka paipu welded no ka mea ua komo pū me kahi wili weld. ʻAʻole i ʻike ʻia kēia hemahema o ke kūkulu ʻia ʻana o ka paipu seamless a ua manaʻo ʻia he palekana. ʻOiai he ʻoiaʻiʻo ua komo ka paipu welded i kahi humu e hoʻonāwaliwali i ka manaʻo, ua hoʻomaikaʻi ʻia nā ʻenehana hana a me nā ʻōnaehana hōʻoia maikaʻi i ka nui o ka hana o ka paipu welded e like me ka makemake inā ʻaʻole i ʻoi aku kona ʻae ʻana. ʻOiai maopopo ka pōmaikaʻi, ʻo ka hoʻopiʻi ʻana i ka paipu wili ʻole ʻia ʻo ke kaʻina o ka ʻōwili a me ka hoʻolōʻihi ʻana e hana i ka mānoanoa pā ʻokoʻa ke hoʻohālikelike ʻia me ka mānoanoa o nā ʻāpana kila i koho ʻia no ka wili.
ʻO nā kūlana o ka ʻoihana e alakaʻi ana i ka hana ʻana a me nā kikoʻī o ERW a me ka paipu kila maʻemaʻe e hōʻike mau ana i kēlā mau manaʻo. No ka laʻana, koi ʻia ka paipu maʻemaʻe no nā noi kiʻekiʻe kiʻekiʻe, kiʻekiʻe-mehana i ka ʻaila a me ke kinoea, hana mana a me nā ʻoihana lāʻau. ʻO ka paipu welded (ʻoi aku ka maʻalahi o ka hana ʻana a ʻoi aku ka nui o ka loaʻa ʻana) ua kuhikuhi ʻia ma nā ʻoihana āpau inā ʻaʻole ʻoi aku ka mahana, ke kaomi a me nā ʻano lawelawe ʻē aʻe ma mua o nā ʻāpana i hōʻike ʻia ma ke kūlana kūpono.
Ma nā palapala hoʻolālā, ʻaʻohe ʻokoʻa o ka hana ma waena o ERW a me ka paipu kila ʻole. ʻOiai hiki ke hoʻololi like ʻia nā mea ʻelua, ʻaʻole kūpono ke kuhikuhi ʻana no ka seamless ke hana like ka paipu welded cheap.
4. E hōʻike mai iā mākou i kāu mau kikoʻī, e noi i kahi ʻōlelo a loaʻa koke kāu paipu
Hoʻopiha piha ʻia ʻo Jindalai Steel Group me nā mea waiwai maikaʻi loa o nā huahana paipu kila i hoʻopaʻa ʻia i ka ʻoihana. Hoʻokumu mākou i kā mākou waiwai mai nā hale wili a puni ʻo Kina, e hōʻoia ana i ka poʻe kūʻai mai e loaʻa koke i ka paipu me ka nānā ʻole ʻana i nā kapu kānāwai e pili ana.
Hiki iā Jindalai ke kōkua iā ʻoe e ʻike i ke kaʻina hana kūʻai paipu mai ka hoʻomaka a hiki i ka pau ʻana e hōʻoia i ka loaʻa koke ʻana o kāu mea e pono ai ke hiki ke kūʻai. Inā kūʻai ʻia kahi paipu i kou wā e hiki mai ana, e noi i kahi ʻōlelo. Hāʻawi mākou i kahi mea e loaʻa pololei iā ʻoe nā huahana āu e makemake ai me ka wikiwiki.
