?Loaʻa i ka paipu kila Welded kahi kaʻina hana maʻalahi, kiʻekiʻe ka hana pono, nā ʻano like ʻole a me nā kikoʻī, a me nā mea liʻiliʻi, akā ʻoi aku ka haʻahaʻa o kona ikaika ma mua o nā paipu kila ʻole.Mai ka makahiki 1930, me ka hoʻomohala wikiwiki ʻana o ke kila kiʻekiʻe kiʻekiʻe e hoʻomau mau ana i ka hana ʻana a me ka holomua o ka welding a me ka ʻenehana nānā ʻana, ua hoʻomaikaʻi mau ʻia ka maikaʻi o nā welds, ua hoʻonui ʻia nā ʻano a me nā kikoʻī o nā paipu kila welded, a ʻoi aku. Ua hoʻololi nā māla hou aku i ke kila non-ferrous.Paipu kila humuhumu.Hoʻokaʻawale ʻia nā paipu kila welded i nā paipu wili wili pololei a me nā paipu wili wiliwili spiral e like me ke ʻano o nā welds.
He maʻalahi ke kaʻina hana o ka paipu wili wili pololei, ʻoi aku ka maikaʻi o ka hana, haʻahaʻa ke kumu kūʻai, a wikiwiki ka hoʻomohala ʻana.ʻOi aku ka nui o ka ikaika o ka paipu i hoʻopaʻa ʻia ma mua o ka paipu wili wili pololei, a hiki ke hana ʻia ka paipu wili me ke anawaena nui me ka billet ʻoi aku ka liʻiliʻi, a hiki ke hana ʻia ka paipu welded me nā anawaena paipu like ʻole billet o ka laula like.Eia naʻe, ke hoʻohālikelike ʻia me ka lōʻihi like o ka paipu seam pololei, hoʻonui ʻia ka lōʻihi o ka weld e 30 ~ 100%, a ʻoi aku ka wikiwiki o ka hana.No laila, ʻo ka hapa nui o nā paipu i hoʻopaʻa ʻia me nā anawaena liʻiliʻi e hoʻohana i ka wiliwili wili pololei, a ʻo ka hapa nui o nā paipu wili me nā anawaena nui e hoʻohana i ka wiliwili spiral.
1. ʻO nā paipu kila welded no ka lawe ʻana i ka wai haʻahaʻa i kapa ʻia ʻo nā paipu welded maʻamau, i ʻike mau ʻia ʻo nā paipu ʻeleʻele.He paipu kila welded no ka lawe ʻana i nā wai kaomi haʻahaʻa haʻahaʻa e like me ka wai, ke kinoea, ka ea, ka aila a me ka mahu mehana a me nā kumu ʻē aʻe.Hoʻokaʻawale ʻia ka mānoanoa o ka pā o ka paipu kila i ka paipu kila maʻamau a me ka paipu kila mānoanoa;ua māhele ʻia ke ʻano o ka hopena o ka paipu i loko o ka paipu kila non-threaded (smooth pipe) a me ka pipe steel threaded.Hōʻike ʻia ka kikoʻī o ka paipu kila e ke anawaena nominal (mm), kahi kokoke i ke anawaena o loko.He mea maʻamau ka hōʻike ʻana i nā iniha, e like me 11/2 a pēlā aku.Ma waho aʻe o ka hoʻohana pololei ʻana i ka lawe ʻana i nā wai, hoʻohana nui ʻia nā paipu kila welded no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa e like me nā paipu kumu o nā paipu kila welded no ka lawe ʻana i ka wai haʻahaʻa.
2. Galvanized welded kila paipu no ka haʻahaʻa-puʻe wai lawe mea no hoi i kapaia galvanized uila welded kila paipu, maʻamau i ike i keʻokeʻo paipu.He paipu kila i hoʻohana ʻia no ka lawe ʻana i ka wai, ke kinoea, ka aila ea, ka mahu mehana, ka wai mehana a me nā mea ʻē aʻe.Hoʻokaʻawale ʻia ka mānoanoa o ka pā o ka paipu kila i ka paipu kila galvanized maʻamau a me nā paipu kila galvanized mānoanoa;ua māhele ʻia ke ʻano o ka hopena o ka paipu i loko o ka paipu kila galvanized ʻole a me ka pipe galvanized steel pipe.Hōʻike ʻia ka kikoʻī o ka paipu kila e ke anawaena nominal (mm), kahi kokoke i ke anawaena o loko.He mea maʻamau ka hōʻike ʻana i nā iniha, e like me 11/2 a pēlā aku.
3. ʻO ka pahu uea kalapona maʻamau he paipu kila i hoʻohana ʻia no ka pale ʻana i nā uea i nā papahana hoʻonohonoho uila e like me nā hale ʻoihana a me nā hale kīwila, hoʻokomo i nā mīkini a me nā lako.
4. ʻO ka paipu kila i hoʻopaʻa ʻia i ka hili pololei he paipu kila me ke kuʻina weld e like me ke kuhikuhi longitudinal o ka paipu kila.Hoʻokaʻawale pinepine ʻia i ka metric uila welded steel paipu, uila welded thin-walled paipu, transformer cooling aila paipu a pēlā aku.
5. Spiral seam submerged arc welded kila paipu no ka pressurized wai halihali mea he spiral seam kila paipu i hoʻohana 'ia no ka pressurized wai halihali, ka mea, he wela-owili kila kaula wili e like me ka paipu blank, pinepine i hanaia e ka mehana piko, a welded e pālua- ʻaoʻao submerged arc welding.Loaʻa i ka paipu kila ka mana hoʻoikaika ikaika a me ka hana wiliwili maikaʻi.Ma hope o nā ʻike ʻepekema koʻikoʻi a me nā hoʻāʻo, palekana a hilinaʻi hoʻi e hoʻohana.He nui ke anawaena o ka paipu kila, he kiʻekiʻe ka maikaʻi o ka lawe ʻana, a hiki ke mālama ʻia ka hoʻopukapuka ʻana i nā pipeline.Hoʻohana nui ʻia no nā pipelines no ka lawe ʻana i ka aila a me ke kinoea maoli.
6. Spiral seam kiʻekiʻe-frequency welded kila paipu no ka pressurized wai halihali ua hana ia me ka wela-owili kila coil e like me ka paipu blank, hana pinepine ia e mehana poepoe, a welded e kiʻekiʻe-frequency lap welding.Paipu kila welo.Loaʻa i ka paipu kila ka mana paʻa ikaika a me ka plasticity maikaʻi, kahi kūpono no ka wili a me ka hana.Ma hope o nā hoʻokolohua koʻikoʻi a me ka ʻepekema, palekana a hilinaʻi hoʻi e hoʻohana.ʻO ka paipu kila ke anawaena nui a me ka maikaʻi o ka lawe ʻana, a hiki ke mālama i ka hoʻopukapuka ʻana i nā pipelines.Hoʻohana nui ʻia no ka waiho ʻana i nā pipeline no ka lawe ʻana i ka aila, ke kinoea maoli, etc.
7. 'O ka mea ma'amau, ua hana 'ia ka paipu kila i ho'opa'a 'ia i ka pu'upu'u arc no ka lawe 'ana i ka wai mehana e like me ka pahu blank, a ua hana pinepine 'ia i loko o ka pu'u wela.Hana ʻia ʻo ia me ka lua-ʻaoʻao ʻakomi hoʻoheheʻe arc a i ʻole ka ʻaoʻao hoʻokahi no ka wai, ke kinoea a me ka ea.
8. Ua hana 'ia ka pu'upu'u huila ki'eki'e alapine ki'eki'e no ka lawe 'ana i ka wai ha'aha'a ha'aha'a me ke kila kila wela e like me ka paipu blank, i hana pinepine 'ia e ka pulina mehana, a ua wili 'ia e ka wili pu'e ki'eki'e.Hoʻohana ʻia ia no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa..
9. ʻO nā paipu kila i hoʻopaʻa ʻia no nā puʻu i hana ʻia me nā wili kila wela e like me nā tube blanks, i hana pinepine ʻia e nā spiral mahana, a i hana ʻia me nā ʻaoʻao ʻelua i hoʻopaʻa ʻia i loko o ke arc a i ʻole ka wili kiʻekiʻe.Hoʻohana ʻia lākou no nā puʻu kumu e like me nā hale kūkulu kīwila, nā uapo, a me nā alahaka.E hoʻohana i nā paipu kila.
