1. Hoʻohana ʻia nā paipu kila maʻemaʻe no ka hana ʻana i nā paila haʻahaʻa haʻahaʻa a me waena, nā paipu mokumahu wela, nā paipu wai paila, nā paipu pā wai hoʻoluʻu a me nā paipu mahu wela, nā paipu uwahi nui, nā paipu uwahi liʻiliʻi a me nā paipu pōhaku lepo no nā paila locomotive.E ho'ohana i ke kila kila wela a i 'ole ke anu (dial).Hana nui ʻia me 10, 20 kila, i hoʻohui ʻia e hōʻoia i ka haku melemele a me nā waiwai mechanical e hana i ka hoʻāʻo ʻana i ka wai, crimping, flaring, flattening a me nā hoʻokolohua ʻē aʻe.ʻO ka ʻōwili wela i ka hāʻawi ʻana i ka mokuʻāina ʻo ka ʻōwili wela, ka ʻōwili anuanu (dial) i ka lawe ʻana i ka mokuʻāina mālama wela.Hoʻoholo ʻia ke anawaena o loko o ka paipu kila e ka lōʻihi o waho o ke anawaena o ka drill bit o ka mīkini sizing.
2. Seamless kila paipu ma hope o ka nui ana, i loko o ka hooluolu hale kiaʻi, ma o ka wai hooluolu, kila paipu ma hope o ka hooluolu ana, e straightened.Ma hope o ka hoʻopololei ʻana, hoʻouna ʻia ka paipu kila e ke kāʻei conveyor i ka mea ʻike kīnā metala (a i ʻole ka hoʻāʻo ʻana i ke kaomi wai) no ka ʻike hewa o loko.Inā loaʻa nā māwae, nā ʻōpū a me nā pilikia ʻē aʻe i loko o ka paipu kila, e ʻike ʻia.ʻO Shaanxi Huichuan ke kūʻai aku i ke kila mai Laigang, Shougang, Baotou kila, Handan Steel, Metallurgical steel, Tang Steel, Jiusteel, Laigang, Angang, Longgang Ma Steel a me nā hale kila hōʻoia maikaʻi ʻē aʻe, i ka laina me ke kūlana aupuni.
3. Ma hope o ka nānā ʻana i ka maikaʻi, e pena i ka helu paipu, kikoʻī, helu pūʻulu hana a pēlā aku.A ma ka crane i loko o ka hale kūʻai.Ma lalo o ke kūlana o ka ʻāpana ʻāpana like ʻole, ʻoi aku ka ikaika o ka paipu kila i hoʻohana ʻia no ka hoʻolālā ʻana i ke kūpaʻa kūlou a puni a ʻoi aku ka rigidity ma mua o ke kila square, ke kila pālahalaha a me nā ʻano kila ʻē aʻe, no ka mea, ʻo ke kūpaʻa kūlou o ke kila square, ke kila pālahalaha a me nā ʻano like ʻole. 'ano o ke kila i ikaika directivity, akā, i ka kuʻekuʻe kū'ē o ke kila paipu mea ole wale no directivity, akā, i ka ikaika loa kuʻi kūlou i kēlā me kēia hui nuipa.
