Wahi a ke ʻano hana ʻana, hiki ke hoʻokaʻawale ʻia nā paipu kila i ʻelua mau ʻāpana: nā paipu kila humuhumu a me nā paipu kila i hoʻopaʻa ʻia. I waena o lākou, ʻo nā paipu kila ERW ke ʻano nui o nā paipu kila i hoʻopaʻa ʻia. I kēia lā, kamaʻilio nui mākou e pili ana i ʻelua ʻano paipu kila i hoʻohana ʻia ma ke ʻano he mea maka o ka uhi: nā paipu uhi humuhumu a me nā paipu uhi ERW.
Paipu ʻili humuhumu ʻole - paipu ʻili i hana ʻia me ka paipu kila humuhumu ʻole; ʻO ka paipu kila humuhumu ʻole e pili ana i ka paipu kila i hana ʻia e ʻehā mau ʻano o ka ʻōwili wela, ka ʻōwili anu, ke kahakiʻi wela a me ke kahakiʻi anu. ʻAʻohe wili o ke kino paipu ponoʻī.
Kino ERW - ʻO ka paipu kila ERW (Electric Resistant Weld) i hana ʻia me ka paipu uila i hoʻopaʻa ʻia e pili ana i ka paipu longitudinal seam i hoʻopaʻa ʻia i hana ʻia e ka hoʻopaʻa ʻana i ke alapine kiʻekiʻe. Hana ʻia nā pepa kila maka (coils) no nā paipu uila mai ke kila micro-alloy haʻahaʻa kalapona i ʻōwili ʻia e TMCP (kaʻina hana thermomechanical controlled).
1. Paipu kila wili ʻole ke ahonui OD: me ka hoʻohana ʻana i ke kaʻina hana ʻōwili wela, ua hoʻopau ʻia ka nui ma kahi o 8000°C. ʻO ka haku mele ʻana o ka mea maka, nā kūlana hoʻoluʻu, a me ke kūlana hoʻoluʻu o ka ʻōwili he mana nui ia i kona anawaena o waho, no laila he paʻakikī ke kāohi pololei i ke anawaena o waho, a nui ka laulā fluctuation. Paipu kila ERW: ua hana ʻia e ke kūlou anu, a ua hoʻemi ʻia kona anawaena e 0.6%. ʻO ke ʻano o ka mahana o ke kaʻina hana he paʻa mau ia ma ka mahana o ka lumi, no laila ua kāohi pololei ʻia ke anawaena o waho, a he liʻiliʻi ka laulā fluctuation, kahi mea e kōkua ai i ka hoʻopau ʻana i nā buckles ʻili ʻeleʻele;
2. Paipu kila humuhumu me ka hoʻomanawanui mānoanoa o ka paia: Hana ʻia ia ma ka perforating kila poepoe, a nui ka ʻokoʻa o ka mānoanoa o ka paia. Hiki i ka ʻōwili wela ma hope ke hoʻopau hapa i ka ʻokoʻa o ka mānoanoa o ka paia, akā hiki i nā mīkini hou loa ke hoʻoponopono iā ia i loko o ± 5 ~ 10%t. Paipu kila ERW: I ka wā e hoʻohana ai i ka ʻōwili wela i ʻōwili ʻia ma ke ʻano he mea maka, hiki ke hoʻomalu ʻia ka hoʻomanawanui mānoanoa o ka ʻōwili wela hou i loko o 0.05mm.
3. ʻAʻole hiki ke hoʻopau ʻia nā hemahema ma ka ʻili o waho o ka mea hana i hoʻohana ʻia no ke ʻano o ka paipu kila humuhumu i ke kaʻina hana ʻōwili wela, akā hiki ke hoʻopili wale ʻia ma hope o ka pau ʻana o ka huahana i hoʻopau ʻia, ʻo ka hahau helical i waiho ʻia ma hope o ka punching hiki ke hoʻopau hapa ʻia i ke kaʻina hana o ka hōʻemi ʻana i nā paia. Hana ʻia ka paipu kila ERW mai ka ʻōwili wela i ʻōwili ʻia ma ke ʻano he mea maka. ʻO ke ʻano o ka ʻili o ka ʻōwili ua like ia me ke ʻano o ka ʻili o ka paipu kila ERW. He maʻalahi ke kaohi i ke ʻano o ka ʻili o nā ʻōwili wela a he kiʻekiʻe ke ʻano. No laila, ʻoi aku ka maikaʻi o ka ʻili o ka paipu kila ERW ma mua o ka paipu kila humuhumu.
4. Paipu kila wili ʻole oval: me ka hoʻohana ʻana i ke kaʻina hana ʻōwili wela. ʻO ka haku mele maka o ka paipu kila, nā kūlana hoʻoluʻu a me ke kūlana hoʻoluʻu o ka ʻōwili he mana nui ia i kona anawaena o waho, no laila he paʻakikī ke kāohi pololei i ke anawaena o waho, a nui ka laulā fluctuation. Paipu kila ERW: i hana ʻia e ke kūlou anu, ua kāohi pololei ʻia ke anawaena o waho, a liʻiliʻi ka laulā fluctuation.
5. Hoʻāʻo Tensile ʻO nā waiwai tensile o ka paipu kila seamless a me ka paipu kila ERW e kūlike me nā kūlana API, akā ʻo ka ikaika o ka paipu kila seamless ma ka palena kiʻekiʻe, a ʻo ka ductility ma ka palena haʻahaʻa. I ka ʻaoʻao ʻē aʻe, ʻo ka helu kuhikuhi ikaika o ka paipu kila ERW ke kūlana maikaʻi loa, a ʻo ka helu kuhikuhi plasticity he 33.3% kiʻekiʻe ma mua o ke kūlana. ʻO ke kumu, ma ke ʻano he mea maka no ka paipu kila ERW, ua hōʻoia ʻia ka hana o ka coil i ʻōwili wela ʻia e ka micro-alloy smelting, ka hoʻomaʻemaʻe ʻana i waho o ka umu, a me ka hoʻomalu ʻana a me ka ʻōwili ʻana; plastic. He kūlike kūpono.
6. ʻO ka mea maka o ka paipu kila ERW he ʻōwili wela, nona ka pololei kiʻekiʻe loa i ke kaʻina hana ʻōwili, hiki ke hōʻoia i ka hana like o kēlā me kēia ʻāpana o ka ʻōwili.
7. ʻO ka mea maka o ka paipu wili kila ERW i ʻōwili wela ʻia me ka nui o ka palaoa e hoʻohana ana i ka billet hoʻolei mau ākea a mānoanoa, he mānoanoa ka papa paʻa palaoa maikaʻi o ka ʻili, ʻaʻohe wahi o nā kristal kolamu, ka porosity shrinkage a me nā pores, he liʻiliʻi ka ʻokoʻa o ka haku mele. , a he paʻa ka hale; ka kaohi ʻana i ke kaʻina hana ʻōwili ma hope ʻO ka hoʻohana ʻana i ka ʻenehana ʻōwili anu e hōʻoiaʻiʻo pū i ka nui o ka palaoa o ka mea maka.
8. Pili ka hoʻāʻo kū'ē paheʻe o ka paipu kila ERW i nā ʻano o ka mea maka a me ke kaʻina hana o ka paipu. ʻOi aku ka maikaʻi o ka like ʻana o ka mānoanoa o ka paia a me ka ovality ma mua o nā paipu kila seamless, ʻo ia ke kumu nui i ʻoi aku ka kiʻekiʻe o ke kū'ē hiolo ma mua o nā paipu kila seamless.
9. Hoʻāʻo hopena Ma muli o ka paʻakikī o ka mea kumu o ka paipu kila ERW he mau manawa kiʻekiʻe ma mua o ka paipu kila seamless, ʻo ka paʻakikī o ka weld ke kī i ka paipu kila ERW. Ma ka kaohi ʻana i ka nui o nā haumia i loko o ka mea maka, ke kiʻekiʻe a me ke kuhikuhi o ka burr ʻoki, ke ʻano o ka lihi hana, ke kihi welding, ka wikiwiki welding, ka mana hoʻomehana a me ke alapine, ka nui o ka extrusion welding, ka mahana retraction alapine waena a me ka hohonu, ka lōʻihi o ka ʻāpana hoʻoluʻu ea a me nā ʻano hana ʻē aʻe i hōʻoia ʻia. Hiki i ka hopena weld ikehu ma mua o 60% o ka metala kumu. Me ka hoʻonui hou ʻana, hiki i ka ikehu hopena o ka weld ke kokoke i ka ikehu o ka metala kumu, e hōʻoiaʻiʻo ana i ka hana pilikia ʻole.
10. Hoʻāʻo pahū ʻOi aku ka kiʻekiʻe o ka hana hoʻāʻo pahū o nā paipu kila ERW ma mua o nā koi maʻamau, ʻo ia hoʻi ma muli o ke ʻano like o ka mānoanoa o ka paia a me ke anawaena like o waho o nā paipu kila ERW.
