Nui nā ala e ʻoki ai i nā paipu kila kalapona, e like me ka ʻoki ʻana i ke kinoea oxyacetylene, ka ʻoki plasma ea, ka ʻoki ʻana i ka laser, ka ʻoki uea, a me nā mea ʻē aʻe, hiki ke ʻoki i ke kila kalapona. ʻEhā mau ʻano ʻoki maʻamau:
(1) ʻO ke ala ʻoki ahi: ʻO kēia ʻano ʻokiʻoki ke kumu kūʻai haʻahaʻa haʻahaʻa loa, akā ʻoi aku ka nui o ka ʻai ʻana i nā paipu wai ʻole a maikaʻi ʻole ka maikaʻi o ka ʻoki. No laila, hoʻohana pinepine ʻia ka ʻoki ahi lima ma ke ʻano he ʻokiʻoki kōkua. Eia nō naʻe, ma muli o ka hoʻomaikaʻi ʻana o ka ʻenehana ʻoki ahi, ua hoʻohana kekahi mau hale hana i ka mīkini ʻoki ʻoki ahi nui i ke ʻano kumu nui no ka ʻoki ʻana i ka wai kalapona kila seamless tubes.
(2) ʻO ke ʻano shearing: ʻO kēia ʻano hana kiʻekiʻe ka hana hana a me ke kumu kūʻai haʻahaʻa. ʻOki nui ʻia nā paipu kila me ke kalapona liʻiliʻi a me nā paipu kila haʻahaʻa ma ka ʻako ʻana. I mea e hoʻomaikaʻi ai i ka ʻoki ʻoki ʻana, hoʻohana ʻia kahi mīkini ʻāwīwī nui-tonnage no ka ʻāwī pālua; i mea e hōʻemi ai i ke kiʻekiʻe palahalaha o ka hope o ka paipu kila i ka wā o ka ʻoki ʻana, hoʻohana maʻamau ka ʻoki ʻoki i kahi ʻano ʻano. No nā paipu kila maʻemaʻe i hiki ke ʻoki i nā māwae, ua hoʻomehana ʻia nā paipu kila i 300 ° C i ka wā e ʻako ai.
(3) ʻO ke ala haʻihaʻi: ʻo ka mea hana i hoʻohana ʻia he paʻi haʻihaʻi. ʻO ke kaʻina o ka haki ʻana, ʻo ia ka hoʻohana ʻana i ka lama ʻoki e ʻoki i nā puka a pau ma ka paipu wai nahā i koho mua ʻia, a laila e hoʻokomo i loko o kahi paʻi wāwahi, a hoʻohana i ke koʻi triangular e wāwahi. ʻO ka mamao ma waena o nā helu ʻelua he 1-4 mau manawa ke anawaena Dp o ka paipu blank.
(4) ʻO ke ala ʻoki: ʻO kēia ʻano ʻokiʻoki ʻoi aku ka maikaʻi o ka ʻoki ʻana a hoʻohana nui ʻia i nā paipu kila kila, nā paipu kila kiʻekiʻe, a me ka wai. nā paipu lauwili ʻole, ʻoi aku ka nui no ka ʻoki ʻana i nā paipu kila maʻemaʻe ʻole a me nā paipu kila kila kiʻekiʻe. ʻO nā mea ʻili ʻili ʻo ia nā ʻili kakaka, nā ʻili band a me nā ʻili pōʻai. Hoʻohana ʻia nā ʻuala pōʻai anuanu me nā ʻāpana kila kiʻekiʻe no ka ʻili anu anuanu; hoʻohana ʻia nā ʻeli pōʻai anuanu me nā ʻili carbide no nā ʻili kila kila kiʻekiʻe.
ʻO nā mea e mālama ai no ka ʻoki ʻana i ka paipu kila kalapona:
(1) ʻO nā paipu kila galvanized a me nā paipu kila kalapona me ke anawaena inoa ʻoi aku ka liʻiliʻi a i ʻole like me 50mm kūpono maʻamau no ka ʻoki ʻana me ka mea ʻoki paipu;
(2) Pono e ʻoki ʻia nā paipu piʻi kiʻekiʻe a me nā paipu me ka manaʻo paʻakikī e nā ʻano mechanical e like me nā mīkini ʻili a me nā mīkini. Inā hoʻohana ʻia ka lapalapa oxyacetylene a i ʻole ka ʻoki ion, pono e hoʻoneʻe ʻia ka wahi i hoʻopili ʻia o ka ʻokiʻoki, a ʻo kona mānoanoa ʻaʻole i emi iho ma mua o 0.5mm;
(3) Pono e ʻoki ʻia nā paipu kila kila e nā ʻano mechanical a i ʻole plasma;
Hiki ke ʻoki ʻia nā paipu kila ʻē aʻe me ka lapalapa oxyacetylene.
