20# ka wai maʻemaʻe kila paipu mea hana
ʻO ka paipu wai he ʻano paipu kila me ka ʻāpana hakahaka a ʻaʻohe weld mai ka mua a i ka hopena. ʻO ka paipu kila he ʻāpana puha, kahi i hoʻohana nui ʻia e like me ka paipu no ka lawe ʻana i ka wai, aila, kinoea maoli, kinoea, wai a me kekahi mau mea paʻa. Ke hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, ʻo ka paipu kila ke kulou like a me ka ikaika torsional a me ke kaumaha māmā. He kila pauku waiwai. Hoʻohana nui ʻia ia i ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical, e like me ka paipu ʻaila hinu, ka pahu hoʻoili kaʻa, ka pahu kaʻa a me ka scaffold kila i hoʻohana ʻia i ke kūkulu ʻana.
ʻO ka paipu wai he paipu i hoʻohana kūikawā ʻia no ka lawe ʻana i ka media me nā waiwai wai.
Ma waho aʻe o ka media wai e like me ka wai, ka aila a me ka hoʻonā, hiki ke kahe ka media paʻa e like me ka cement, ka palaoa a me ka lanahu pulverized ma lalo o kekahi mau kūlana.
Hiki ke hana ʻia nā paipu wai me ke kila, nā metala non-ferrous e like me ke keleawe a me ka titanium, a me nā mea ʻaʻole metala e like me ka plastic.
Pono ka ʻāpana o ka paipu wai, akā hiki ke ʻano ʻehā, triangular a i ʻole kekahi ʻano ʻē aʻe. Pono kekahi mau mea hana e hoʻohana i ka paipu rectangular ma muli o nā kūlana liʻiliʻi, akā hoʻohana ka hapa nui i ka paipu pōʻai. ʻO ka paipu pōʻai ka liʻiliʻi liʻiliʻi o ka ʻāpana / ʻāpana i nā ʻāpana geometric āpau, ʻo ia hoʻi, hiki ke loaʻa ka ʻāpana i loko nui loa ma lalo o ke ʻano o ka hoʻohana ʻana i ka nui o nā mea.
Hoʻohana nui ʻia ka paipu kila i ka lawe ʻana i ka wai i loko o ka nohona hou no ka haʻahaʻa haʻahaʻa a me ka ikaika kiʻekiʻe. Wahi a kāna kaʻina hana, ua māhele ʻia nā paipu kila i nā paipu kila ʻole a me nā paipu welded. Hoʻokaʻawale ʻia nā paipu welded i nā paipu wili wili pololei kiʻekiʻe (ERW), nā paipu wiliwili spiral (SSAW), nā paipu wili arc submerged (UOE), a pēlā aku. Me ka hoʻomohala ʻana a me ka holomua o ka ʻepekema waiwai, hoʻokumu ʻana i ka ʻenehana a me nā lako ʻāpana, ua hoʻomohala nui ʻia nā paipu welded. Loaʻa ka maikaʻi o ka paipu welded o ka ʻoi aku ka mānoanoa o ka paia, ka pololei kiʻekiʻe, ka liʻiliʻi o ka ikehu a me ka hana kiʻekiʻe ma mua o ka paipu seamless. I ka wā ma mua, aneane 100% o ka paipu ʻole i hoʻohana ʻia no ka paipu ʻaila a me ke kinoea (API standard). I kēia lā, ʻoi aku ma mua o 95% o lākou i hoʻololi ʻia e ka paipu welded ma ʻAmelika Hui Pū ʻIa, Iapana a me nā ʻāina kūkulu ʻEulopa.
① ʻO ka maʻamau, ʻo ka mahana lawelawe o nā paipu paila ma lalo o 450 ℃, a ʻo nā paipu home ka mea nui i hana ʻia me ka No. 10 a me ka No.
②Loaʻa pinepine nā paipu paila kiʻekiʻe i ka wela kiʻekiʻe a me nā kūlana kiʻekiʻe. E oxidized a corroded nā paipu ma lalo o ka hana o ke kinoea a me ka mahu. Pono ka paipu kila e loaʻa ka ikaika mau loa, ka anti-oxidation kiʻekiʻe a me ka hana corrosion a me ka paʻa paʻa maikaʻi.
