Hoʻohana nui ʻia nā huahana kila kila ma nā ʻoihana he nui a me nā noi ma muli o kā lākou hana maikaʻi loa a me nā waiwai. I kēia lā, e kūkākūkā mākou i ka paipu kila kila ʻole a me ka paipu kila kila ERW, a me ka ʻokoʻa ma waena o nā huahana ʻelua.
Aia kekahi mau ʻokoʻa ma waena o ka paipu kila kila ERW a me ka paipu wili ʻole kila kila. ʻO ka ERW Pipe ka pōkole no ka Electric Resistance Welding. Hoʻohana ʻia ia no ka lawe ʻana i nā wai e like me nā wahie, nā kinoea, a me nā mea ʻē aʻe, me ka nānā ʻole i ke kaomi, a he kuleana koʻikoʻi ia i nā pipelines a puni ka honua. I ka manawa like, he paipu kila wili ʻole ia. Hoʻohana ʻia nā paipu kila huinaha a me nā ʻāpana ʻehā me ka ʻole o nā hui a me nā ʻaoʻao hakahaka no ka lawe ʻana i nā wai ma muli o ko lākou ikaika kūlou kiʻekiʻe a me ka torsion, a no ka hana ʻana i nā ʻāpana kūkulu a me nā ʻāpana mechanical. Ma keʻano laulā, hoʻohana ʻia nā paipu ERW a me nā paipu kila wili ʻole no nā kumu like ʻole.
Hana ʻia nā paipu kila kila humuhumu ʻole mai nā bila poepoe, ʻoiai ʻo nā paipu kila kila ERW i hana ʻia mai nā ʻōwili wela. ʻOiai he ʻokoʻa loa nā mea maka ʻelua, pono e hoʻomaopopo ʻia ʻo ke ʻano o ka huahana hope loa - nā paipu e hilinaʻi piha ʻia i kēia mau mea ʻelua - ka kaohi maikaʻi i ka wā o ka hana ʻana a me ke kūlana mua a me ka maikaʻi o nā mea maka. Hana ʻia nā paipu ʻelua i ke kila kila o nā papa like ʻole, akā ʻo ka mea maʻamau ka paipu i hana ʻia i ke kila kila 304.
Hoʻomehana ʻia ka ʻōwili poepoe a hoʻokuʻi ʻia ma luna o ke koʻokoʻo i puka ʻia a hiki i ka wā e lilo ai i ʻano hakahaka. Ma hope iho, hoʻomalu ʻia ko lākou lōʻihi a me ka mānoanoa e nā ʻano extrusion. I ke ʻano o ka hana ʻana o nā paipu ERW, ʻokoʻa loa ke kaʻina hana. Kūlou ka ʻōwili i ke kuhikuhi axial, a hoʻopaʻa ʻia nā ʻaoʻao converging ma kona lōʻihi holoʻokoʻa e ka hoʻopaʻa ʻana i ke kūʻē.
Ua hoʻākoakoa piha ʻia nā paipu kila kila humuhumu ʻole ma ka laina hōʻuluʻulu a loaʻa i ka OD a hiki i ka 26 ʻīniha. Ma ka ʻaoʻao ʻē aʻe, ʻoiai nā ʻoihana kila holomua loa me ka ʻenehana ERW hiki ke hoʻokō i kahi anawaena waho o 24 ʻīniha.
Ma muli o ka hoʻopuka ʻia ʻana o nā paipu humuhumu ʻole, ʻaʻohe o lākou mau hono ma ke kuhikuhi axial a radial paha. ʻO nā paipu ERW, ma ka ʻaoʻao ʻē aʻe, hana ʻia ma ke kulou ʻana i nā wili ma ko lākou axis waena no laila ua hoʻopaʻa ʻia lākou ma ko lākou lōʻihi holoʻokoʻa.
Ma keʻano laulā, hoʻohana ʻia nā paipu humuhumu no nā noi kaomi kiʻekiʻe, ʻoiai hoʻohana ʻia nā paipu ERW no ka lawelawe ma nā wahi kaomi haʻahaʻa a me waena.
Eia kekahi, hāʻawi ʻia i nā ʻano palekana kūlohelohe o nā paipu humuhumu ʻole, hoʻohana nui ʻia lākou i ka ʻaila a me ke kinoea, ka hoʻomaʻemaʻe ʻaila a me nā ʻoihana kemika ʻē aʻe, a pono kahi kulekele ʻaʻohe leakage e hōʻoia i ka palekana o nā kānaka a me nā ʻoihana. I ka manawa like, hiki ke hoʻohana ʻia nā paipu ERW i hana maikaʻi ʻia ma lalo o ka kaohi koʻikoʻi no nā lawelawe like ʻole ma mua o nā lawelawe maʻamau e like me ka halihali wai, scaffolding a me ka pā.
Ua ʻike ʻia ʻo ka hoʻopau ʻana o loko o nā paipu ERW e hoʻomalu mau ʻia e nā ʻano kaohi maikaʻi, no laila ʻoi aku ka maikaʻi o lākou ma mua o nā paipu humuhumu ʻole.
I ke ʻano o ASTM A53, ʻo ke ʻano S ke ʻano he seamless. ʻAno F - umu, akā ʻo ka hoʻoheheʻe ʻana, ʻano E - ka hoʻoheheʻe kū'ē. ʻO ia wale nō. ʻO kēia ke ala maʻalahi loa e hoʻoholo ai inā he seamless a i ʻole ERW kahi paipu.
Manaʻo kōkua: ʻOi aku ka kaulana o ka ASTM A53 Grade B ma mua o nā papa ʻē aʻe. Hiki ke ʻōlohelohe kēia mau paipu me ka ʻole o ka uhi ʻana, a i ʻole hiki ke galvanized a hoʻoheheʻe wela ʻia a hana ʻia me ka hoʻohana ʻana i kahi kaʻina hana welded a seamless paha. Ma ka ʻāpana aila a me ke kinoea, hoʻohana ʻia nā paipu A53 no nā noi kūkulu a me nā noi koʻikoʻi ʻole.
Inā makemake ʻoe i ʻike hou aku e pili ana i kēia papahana, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou no ke kūlana o kēia manawa, ka ʻike pili o ka hui papahana, a pēlā aku.
