ʻEkolu hana hana o ka paipu welded

Hoʻokaʻawale ʻia ka paipu kila i ka paipu kila ʻole a me ka paipu kila welded e like me nā ʻano hana.ʻO kēia manawa mākou e hoʻolauna nui ai i ka paipu kila welded, ʻo ia hoʻi, ka paipu kila welded. ʻO kāna hana ʻana ʻo ia ke kulou i ka paipu blank (pā kila a me ke kaula kila i loko o ke ʻano o ka ʻāpana cross-section a me ka nui o ka paipu ma nā ʻano hana like ʻole, a laila weld i ka weld. ma nā ʻano hana kuʻi ʻokoʻa e loaʻa ai ka paipu kila.

Ke hoʻohālikelike ʻia me ka paipu kila welded seamless, loaʻa iā ia ka pololei o ka huahana me nā hiʻohiʻona o ka precision kiʻekiʻe, ʻoi aku ka mānoanoa o ka paia.mea maʻalahi maʻalahi, wahi papahele liʻiliʻi, hana mau i ka hana a me ka hana maʻalahi, hiki ke hoʻokaʻawale ʻia ka paipu welded i loko o ka spiral.paipu wiliwili ʻia i loko o ka poʻo, ka humu pololei ʻaoʻao ʻelua ʻaoʻao arc wili paipu a me ka paipu wili kuʻi.

1. ʻO ke kaʻina hana o ka paipu kila spiral penei:

ʻO nā mea maka o ka paipu kila spiral he strip coil, welding wire a me flux.lawe ʻia ma ka ʻili, a bent.The weld gap control device i hoʻohana ʻia e hōʻoia i ka hoʻokō ʻana o ka weld i nā koi kuʻi.ʻO ke anawaena o ka paipu, misalignment a me ka weld gap e mālama pono ʻia. Ma hope o ka ʻoki ʻana i loko o ka paipu kila hoʻokahi, ʻo nā ʻekolu mua o kēlā me kēia pūʻulu o nā paipu kila e kau ʻia i ka ʻōnaehana nānā mua, no ka nānā ʻana i nā waiwai mechanical, haku mele, fusion state a ka maikaʻi o ka ili o ka weld, a ma o ka hoʻāʻo ʻole ʻana e hōʻoia i ke kūpono o ke kaʻina hana paipu.hiki ke hoʻokomo maʻamau i ka hana.

2.LSAW paipu:

ʻO ka ʻōlelo maʻamau, hana ʻia ka paipu LSAW i ka pā kila ma o nā kaʻina hana like ʻole, e like me ka hoʻoheheʻe ʻana i nā ʻaoʻao ʻelua ʻaoʻao arc.e hoʻonui ana ma hope o ka welding.ʻO nāʻano hana o ka paipu LSAW e komo pū me uo (UOE), Rb (RBE), JCO (JCOE), etc.

Kaʻina hana o ka paipu UOE LSAW:

ʻO ke kaʻina hana o ka UOE longitudinal submerged arc welded pipe ka nui o nā kaʻina hana ʻekolu: ka pā kila ma mua o ke kulou ʻana, ka hana ʻana a me ka hana ʻana o O.Ke hoʻohana nei kēlā me kēia kaʻina i kahi paʻi hana kūikawā e hoʻopau i nā kaʻina hana ʻekolu o ka ʻaoʻao o ka pā kila ma mua o ke kulou ʻana, ka hana ʻana a me ka hoʻokumu ʻana o O i mea e hoʻololi ai i ka pā kila i loko o kahi tube pōʻai. hehi pinepine i ka mīkini hana, 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 i kahi ʻano C.

Hoʻohālikelike o JCO a me nā ʻano hana molding uo:

ʻO ka hoʻokumu ʻana o JCO ka mea e hoʻololi ai i ke kaʻina hana o ka paipu kila mai nā ʻanuʻu ʻelua o ka UO e hana ana i nā paepae he nui.ʻO ka paipu kila i hanaʻia he hiki ke maʻalahi i ka nui o ke anawaena a me ka mānoanoa o ka paia.Hiki iā ia ke hana i nā huahana nui a me nā huahana liʻiliʻi.a me nā huahana caliber nui a me nā huahana kiʻekiʻe Hiki iā ia ke hana i nā paipu kila liʻiliʻi a me nā paipu kila nui.ʻoi aku ka maikaʻi ma ka hana ʻana i nā paipu paia mānoanoa kiʻekiʻe loa i ka hana ʻana i nā paipu paia mānoanoa a liʻiliʻi.Loaʻa iā ia nā mea maikaʻi ʻole ma mua o nā kaʻina hana ʻē aʻe, a hiki ke hoʻokō i nā koi hou aʻe o nā mea hoʻohana no nā kikoʻī paipu kila. Hoʻopili ʻo Uo molding iā u a me O ʻelua mau ʻanuʻu puʻe, kahi i hōʻike ʻia e ka mana nui a me nā huahana kiʻekiʻe. -30% 1 miliona mau tons, kūpono no ka hoʻokumu ʻana i nā kikoʻī hoʻokahi.

3. Pololei humuhumu kiʻekiʻe alapine welded paipu

Hoʻokumu ʻia ka paipu welded kiʻekiʻe kiʻekiʻe (ERW) pololei ma ka hoʻomehana ʻana i ka lihi o ka tube billet me ka hopena o ka ʻili a me ka hopena pili o ke alapine kiʻekiʻe o kēia manawa ma hope o ka hana ʻia ʻana o ka wili wela e ka mīkini hana, a laila hoʻokō ʻia ka wili ʻana. ma lalo o ka hana o ka extrusion roller.
