ʻO ka paipu kila welded he paipu kila i hoʻopaʻa ʻia.ʻO kāna hana ʻana, ʻo ia ke kulou ʻana i ka paipu blank (pā kila a me ke kaula kila) i loko o kahi paipu me ke ʻano o ke ʻano cross-sectional a me ka nui e koi ʻia e nā ʻano hana like ʻole, a laila hoʻohana i nā ʻano hana kuʻi ʻokoʻa e hoʻopaʻa pū ai i ke kuʻina weld.ʻO ke kaʻina hana o ka loaʻa ʻana o nā paipu kila.
Ke hoʻohālikelike ʻia me ka paipu kila maʻemaʻe a me ka paipu welded, loaʻa iā ia nā hiʻohiʻona o ka pololei o ka huahana kiʻekiʻe, ʻoi aku ka pololei o ka mānoanoa o ka paia, nā lako nui maʻalahi, ka wāwae liʻiliʻi, ka hana mau i ka hana, ka hana maʻalahi, a me ka laulā huahana o ka ʻāpana.
Hoʻokahi, ʻO ke kaʻina hana o ka paipu kila spiral e like me kēia:
1. ʻO nā mea maka o ka paipu kila kila, ʻo ia ka wili kila, ka uwea wili a me ka flux.
2. Ma mua o ka hoʻokumu ʻana, hoʻokaʻawale ʻia ke kila kaulahao, ʻoki ʻia, hoʻolālā ʻia, hoʻomaʻemaʻe ʻia ka ʻili, lawe ʻia a hoʻopaʻa mua ʻia.
3. Hoʻohana ʻia ka weld gap control device e hōʻoia i ka hoʻokō ʻana o ka weld gap i nā koi wili, a ʻo ke anawaena paipu, misalignment a me ka weld gap e hoʻomalu pono ʻia.
4. Ma hope o ka ʻoki ʻana i loko o nā paipu kila hoʻokahi, pono nā paipu kila ʻekolu o kēlā me kēia pūʻulu e hoʻopaʻa ʻia i kahi ʻōnaehana nānā mua e nānā i nā waiwai mechanical, haku mele, ke kūlana hui o nā welds, ka maikaʻi o ka ʻili o nā paipu kila a me ka hoʻāʻo ʻole luku. e hōʻoia i ke kūpono o ka hana paipu.Ma hope o kēlā, hiki ke hoʻokomo ʻia i ka hana.
ʻO ka lua, he paipu i hoʻoheheʻe ʻia i loko o ke poʻo.
Hoʻohana maʻamau ka līlū pololei i hoʻopaʻa ʻia i loko o ke arc welded pipe (LSAW) i nā pā kila ma ke ʻano he mea maka, a ke hana nei i nā kaʻina hana like ʻole e hana ai i nā paipu wili ʻia e ka wiliwili arc submerged ʻaoʻao ʻelua a me ka hoʻonui ʻana i ke anawaena ma hope o ka welding.
ʻO nā mea hana nui e pili ana i ka mīkini wili lihi, ka mīkini pre-bending, ka mīkini hana, ka mīkini pre-weld, ka mīkini e hoʻonui ana i ke anawaena, a me nā mea ʻē aʻe.

UOE LSAW paipu kaʻina hana:
ʻO nā kaʻina hana nui ʻekolu o ka UOE LSAW steel pipe forming process e komo pū ana: ka pā kila ma mua o ke kuʻi ʻana, ka hana ʻana a me ka hoʻokumu ʻana o O.Ke hoʻohana nei kēlā me kēia kaʻina hana i kahi paʻi hana kūikawā e hoʻopau i nā kaʻina hana ʻekolu o ke kuʻi mua ʻana i ka ʻaoʻao o ka pā kila, ka hana ʻana o U a me ka ʻO i hoʻokumu ʻia ma ke kaʻina, a hoʻololi i ka pā kila i loko o kahi paipu pōʻai.
JCOE LSAW paipu kaʻina hana:
Hana ʻia: Ma hope o ka hoʻopaʻa ʻana i ka mīkini hana JC0, kaomi ʻia ka hapa mua o ka pā kila i kahi ʻano "J", a laila kaomi ʻia ka hapa ʻē aʻe o ka pā kila i kahi ʻano "J" e hana ai. he ʻano C”, a hoʻopaʻa hope ʻia mai ka waena mai i mea e hoʻohua ai i ke ʻano o ke ʻano o ka paipu "0".
Hoʻohālikelike i nā ʻano hana hoʻoheheʻe JCO a me UO:
ʻO ka hoʻokumu ʻana ʻo JCO ʻo ia ka holomua ʻana o ke kaomi, kahi e hoʻololi ai i ke kaʻina hana o ka paipu kila mai ʻelua mau ʻanuʻu o ka UO e hoʻokumu ana i ka nui-step.I ka wā o ke kaʻina hana, ʻaʻahu like ka deformation o ka pā kila, liʻiliʻi ke koena o ke koʻikoʻi, a ʻaʻole hoʻohua ka ʻili.
ʻO nā paipu kila i hanaʻia heʻoi aku ka maʻalahi i ka nui a me ka laulā kiko'ī o ke anawaena a me ka mānoanoa o ka paia, a hiki ke hana i nā huahana nui a me nā mea liʻiliʻi;hiki iā ia ke hana i nā paipu kila mānoanoa kiʻekiʻe ke anawaena nui, a hiki ke hana i nā paipu kila liʻiliʻi a me ka pā mānoanoa;ʻoi aku ka maikaʻi ma ka hana ʻana i nā paipu paʻa mānoanoa kiʻekiʻe, ʻoi aku ka nui o nā paipu liʻiliʻi a me ke anawaena mānoanoa, i loaʻa nā mea maikaʻi ʻole ma mua o nā hana ʻē aʻe.
Hiki iā ia ke hoʻokō i nā koi hou aʻe o nā mea hoʻohana e pili ana i nā kikoʻī paipu kila.He liʻiliʻi ka hoʻopukapuka kālā, akā ʻoi aku ka haʻahaʻa o ka hana ʻana, a he 100,000 a 250,000 tons ka nui o ka makahiki.
Hoʻokumu ʻia ka hoʻoheheʻe ʻana o UO e U a me ʻO ʻelua mau manawa o ka hoʻoheheʻe ʻana.Hōʻikeʻia ia e ka mana nui a me ka puka kiʻekiʻe.ʻO ka mea maʻamau, hiki i ka hopena makahiki ke hiki i 300,000 a 1 miliona tons, kahi kūpono no ka hana nui o kahi kikoʻī hoʻokahi.
3. humuhumu pololei kiʻekiʻe alapine welded paipu:
ʻO ka hoʻoheheʻe pololei ʻana i ka paipu welded kiʻekiʻe-frequency (ERW) e wela a hoʻoheheʻe i ka lihi o ka paipu paipu ma ka hoʻohana ʻana i ka hopena ʻili a me ka hopena pili o ka manawa kiʻekiʻe ma hope o ka hoʻokumu ʻia ʻana o ka wili wela e ka mīkini hana, a me ke kaomi. lawe ʻia ka welding ma lalo o ka hana a ka extrusion roller e hoʻokō i ka hana.
?Welded kila paipu i maʻalahi kaʻina hana, kiʻekiʻe hana pono, he nui nā ʻano a me nā kikoʻī, a me ka liʻiliʻi o nā lako hana, akā ʻoi aku ka haʻahaʻa o kona ikaika ma mua o ka paipu kila seamless.
Mai ka 1930s, me ka hoʻomohala wikiwiki ʻana o ka hana ʻana i ka ʻōwili mau ʻana o ke kila kila kiʻekiʻe a me ka holomua o ka welding a me ka ʻenehana nānā ʻana, ua hoʻomaikaʻi mau ʻia ka maikaʻi o nā welds, a ua hoʻonui ʻia nā ʻano a me nā kikoʻī o nā paipu kila welded i kēlā me kēia lā. .Paipu kila humuhumu.Hoʻokaʻawale ʻia nā paipu kila welded i nā paipu wili wili pololei a me nā paipu wiliwili spiral e like me ke ʻano o ka weld seam.
Hoʻokaʻawale ʻia ma ke ʻano hana: ka hoʻokaʻawale ʻana i ke kaʻina hana - arc welded pipe, uila kūpaʻa welded pipe, (ke alapine kiʻekiʻe, haʻahaʻa haʻahaʻa) kinoea welded paipu, umu ahi welded paipu.He maʻalahi ke kaʻina hana o ka paipu wili wili pololei, ʻoi aku ka maikaʻi o ka hana, haʻahaʻa ke kumukūʻai, a wikiwiki ka hoʻomohala ʻana.ʻOi aku ka nui o ka ikaika o ka paipu wiliwili spiral ma mua o ka paipu wili wili pololei, a hiki ke hana ʻia ka paipu wili me ke anawaena nui me ka billet haiki, a hiki ke hana ʻia nā paipu welded me nā anawaena like ʻole me ka billet ākea like.Akā i ka hoʻohālikelike ʻia me ka paipu seam pololei o ka lōʻihi like, ua hoʻonui ʻia ka lōʻihi weld e 30 ~ 100%, a ʻoi aku ka haʻahaʻa o ka wikiwiki.
