Ma o ka nānā ʻana, ʻaʻole paʻakikī ka loaʻa ʻana i kēlā me kēia manawapaipu kila mānoanoa, ua hoʻonui ʻia nā paipu thermally, a me nā mea ʻē aʻe, ua hoʻohana ʻia ke kila strip ma ke ʻano he mea hana maka, a ʻo nā paipu i loaʻa ma ka wiliwili paʻa paʻa ma luna o nā mea hoʻoheheʻe kiʻekiʻe e kapa ʻia nā paipu kila mānoanoa. Ma waena o lākou, e like me nā hoʻohana like ʻole a me nā kaʻina hana hoʻihoʻi hope ʻē aʻe, hiki ke hoʻokaʻawale ʻia lākou i nā paipu scaffolding, nā paipu wai, nā uea uea, nā paipu bracket, nā paipu guardrail, etc.). Kūlana no nā paipu wiliwili ʻia me ka pā mānoanoa GB/T3091-2008. ʻO nā paipu wiliwili wai haʻahaʻa haʻahaʻa he ʻano o nā paipu wiliwili pā mānoanoa. Hoʻohana pinepine ʻia lākou no ka lawe ʻana i ka wai a me ke kinoea. Ma hope o ka wili ʻana, aia kahi hoʻāʻo hydraulic hou aʻe ma mua o nā paipu welded maʻamau. No laila, ʻoi aku ka mānoanoa o nā paipu wai haʻahaʻa ma mua o nā paipu welded maʻamau. ʻOi aku ka kiʻekiʻe o nā huaʻōlelo paipu welded.

ʻO nā kūlana nānā no nā paipu kila mānoanoa me ka nui o nā helu penei:
1. Pono e waiho ʻia nā paipu kila mānoanoa no ka nānā ʻana i nā pūʻulu, a pono nā lula batching e hoʻokō i nā lula o nā kūlana huahana pili.
2. ʻO nā mea nānā, ka nui o ka laʻana, nā wahi hoʻohālike, a me nā ʻano hoʻāʻo o nā paipu kila mānoanoa me ka pā pōhaku ma muli o nā lula o nā kikoʻī huahana pili. Me ka ʻae ʻana o ka mea kūʻai mai, hiki ke hoʻohālikelike ʻia nā paipu kila mānoanoa i ʻōwili ʻia i loko o nā pūʻulu e like me ka helu aʻa.
3. Inā ʻaʻole i kūpono nā hopena hoʻāʻo o nā paipu kila mānoanoa i nā koi o nā kūlana huahana, pono e hoʻokaʻawale ʻia nā mea kūpono ʻole, a pālua i ka helu o nā laʻana e koho ʻia mai ka pūʻulu like o nā paipu kila mānoanoa. e hoʻokō i nā mea kūpono ʻole. ka nana hou ana. Inā hāʻule nā ​​hopena o ka nānā hou ʻana, ʻaʻole e hāʻawi ʻia ka pūʻulu o nā paipu kila mānoanoa.
4. No nā paipu kila mānoanoa me nā hopena nānā hou ʻole, hiki i ka mea hoʻolako ke waiho iā lākou no ka nānā ʻana i kēlā me kēia; a i ʻole hiki iā lākou ke hana hou i ka mālama wela a waiho i kahi pūʻulu hou no ka nānā ʻana.
5. Inā ʻaʻohe mea kūikawā i nā kikoʻī o ka huahana, e nānā ʻia ka hui ʻana o nā paipu kila mānoanoa e like me ka hoʻoheheʻe ʻana.
6. Pono e hoʻokō ʻia ka nānā ʻana a me ka nānā ʻana i nā paipu kila mānoanoa e ka ʻoihana hoʻokele ʻenehana.
7. He mau lula ka mea hoʻolako e hōʻoia i ka hoʻokō ʻana o nā paipu kila mānoanoa i hāʻawi ʻia i nā kikoʻī huahana pili. He kuleana ko ka mea kūʻai aku e hana i ka nānā ʻana a me ka nānā ʻana e like me nā kikoʻī kikoʻī pili.

Eia kekahi, aia kekahi mau mea e pono ai mākou e ʻike e pili ana i ka mana welding o nā paipu kila mānoanoa:
1. Ka hoomalu ana i ka wela o na paipu kila me ka manoanoa: Ua pili ka wela weld e ka mana wela o keia manawa. E like me ke ʻano, ʻo ka mana wela o kēia manawa eddy e pili ana i ka alapine o kēia manawa. Ua like ka mana wela o keia manawa me ka huinahalike o ka alapine paipai o keia manawa; Hoʻopili ʻia ka alapine hoʻoulu o kēia manawa e ka voltage stimulation, ka manawa, ka capacitance, a me ka inductance. ʻO ke kumu no ka pinepine hoʻoikaika:
f=1/[2π(CL)1/2]…(1) Ma ke kumu: f-hoʻoikaika i ka alapine (Hz); C-capacitance i loko o ka puka paipai (F), capacitance = mana/voltage; L-encouragement loop Inductance, inductance = magnetic flux/current, hiki ke ʻike ʻia mai ka ʻōlelo ma luna aʻe nei ka hoʻohālikelike ʻana o ke alapine excitation i ke kumu huinahā o ka capacitance a me ka inductance i ke kaapuni excitation, a i ʻole ke kūlike pololei i ke kumu huinahā o. ka uila a me ke au. Ke hoʻololi ʻia ka capacitance, inductance, a i ʻole ka volta a me ke ʻano o ke kaapuni, hiki ke hoʻololi ʻia ka nui o ke alapine excitation e hoʻokō i ke kumu o ka hoʻomalu ʻana i ka wela welding. No ke kila kalapona haʻahaʻa, mālama ʻia ka mahana kuʻi ʻana ma 1250 ~ 1460 ℃, hiki ke hoʻokō i nā koi kuʻi ʻana o ka pā paipu mānoanoa o 3 ~ 5mm. Eia kekahi, hiki ke hoʻokō ʻia ka mahana welding ma ka hoʻoponopono ʻana i ka wikiwiki welding. Ke lawa ʻole ka wela hoʻokomo, ʻaʻole hiki i ka wela wela o ka weld i ka wela weld, a paʻa mau ke ʻano metala, e hopena i ka hui ʻole ʻana a i ʻole ke komo ʻana; inā lawa ʻole ka wela hoʻokomo, ʻoi aku ka wela o ka weld ma mua o ka wela hoʻoheheʻe ʻana, e hopena i ka over-burning a i ʻole nā ​​kulu hoʻoheheʻe ʻia e hoʻoheheʻe ʻia ka weld.

2. Ka hoomalu ana i ka weld awawa o na paipu kila manoanoa me ka paia: E hoouna i ke kaula hao i loko o ka paipu wiliwili, a olokaa ia ma na wili lehulehu. ʻOlokaʻa mālie ʻia ke kila kāʻei e hana i kahi pahu pōʻai me nā hakahaka hāmama. Hoʻoponopono i ke kaomi o ka huila kneading. Pono e hoʻoponopono ʻia ka nui i mea e hoʻomalu ʻia ai ka weld gap ma 1 ~ 3mm a ʻo nā ʻaoʻao ʻelua o ka weld e flush. Inā ʻoi aku ka nui o ke āpau, e hoʻemi ʻia ka hopena kokoke, ʻaʻole lawa ka wela o kēia manawa, a ʻilihune ka hoʻopaʻa ʻana i waena o ka weld, e hopena i ka non-fusion a i ʻole ka haki ʻana. Inā liʻiliʻi ka ʻāpana, e hoʻonui ka hopena kokoke, a ʻoi aku ka nui o ka wela welding, e hoʻopau ʻia ka weld; a i ʻole e hana ka weld i lua hohonu ma hope o ke kāwili ʻia a ʻōwili ʻia, e pili ana i ka ʻili o ka weld.
