Hoʻokaʻawale ʻia nā paipu kila i nā paipu kila ʻole a me nā paipu kila welded e like me ke ʻano hana.ʻO kēia manawa mākou e hoʻolauna nui i nā paipu kila welded, ʻo ia hoʻi, nā paipu kila seamed.ʻO ka hana ʻana, ʻo ia ke kūlou a ʻōwili i nā paipu blanks (nā papa kila a me nā ʻāpana kila) i loko o nā ʻāpana e koi ʻia e nā ʻano hana like ʻole.Hoʻohālikelike me ka seamless kila paipu welded paipu, he kiʻekiʻe huahana precision, oi aku kiʻekiʻe kiʻekiʻe paia mānoanoa precision, maʻalahi mea nui lako, liʻiliʻi kapuaʻi, Nā hiʻohiʻona o ka hana mau a me ka hana maʻalahi i ka hana, ka welded paipu e maheleia i ekolu waeʻano: spiral submerged paipu wiliwili arc, paipu wiliwili arc, humu pololei lua-aoao, a me ka humu pololei.

1. Piula wiliwili ʻia i loko o ke ao

ʻO nā mea maka o ka paipu kila spiral (SSAW) he strip coil, welding wire a me ka flux.Ma mua o ka hana ʻia ʻana, hoʻomaʻemaʻe ʻia ka ʻili a me ka lawe ʻana a me ka mālama mua ʻana.Hoʻohana ʻia ka mea hoʻomalu o ka welding gap e hōʻoia i ka hoʻokō ʻana o ka welding i nā koi wili Pono pono e hoʻomalu pono i ke anawaena paipu, misalignment a me ka weld gap.Ma hope o ka ʻoki ʻana i ka paipu kila hoʻokahi, pono nā paipu mua ʻekolu o kēlā me kēia pūʻulu e hoʻopaʻa ʻia i kahi ʻōnaehana nānā mua loa e nānā i nā waiwai mechanical, haku mele, ʻano hui a me ka ʻili o ka weld.Ma hope o ka nānā ʻana i ka maikaʻi a me ka non-destructive inspection e hōʻoia i ke kūpono o ka hana paipu, hiki ke hoʻokomo ʻia i loko o ka hana.

2. He paipu wiliwili ʻia i loko o ke poʻo

ʻO ka ʻōlelo maʻamau, ʻo ka hili pololei i hoʻopaʻa ʻia i loko o ka arc welded pipe (LSAW) hana ʻia me ka pā kila.Ma hope o nā kaʻina hana like ʻole, hoʻokumu ʻia ka paipu welded e ʻelua ʻaoʻao submerged arc welding a me ka hoʻonui post-weld.ʻO ke ʻano o ka hana ʻana o ka paipu i hoʻoheheʻe ʻia ʻo UO (UOE)., RB (RBE), JCO (JCOE), etc.

UOE hili pololei i hoʻopaʻa ʻia i loko o ke arc welded paipu kaʻina hana:

ʻEkolu mau kaʻina hana i loko o ka UOE LSAW kila paipu kaʻina hana: ka pā kila ma mua o ke kulou 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 ka pre-bending, U ka hana a me O ka hana ʻana o ka lihi o ka pā kila.ʻEkolu kaʻina hana, ua deformed ka pā kila i loko o ka poepoe paipu, ka JCOE hili pololei submerged arc welded paipu hana hana: ma hope o ka hehi nui ma ka JC0 hana mīkini, ka hapa mua o ka mea kila pā ua kaomi i J shape, a laila ka 'ē aʻe. paʻi ʻia ka hapalua o ka pā kila i kahi ʻano J, e hana ana i kahi ʻano C, kaomi ʻia mai ka waena mai e hana i kahi pahu puka "O" hāmama.

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 ka hana ʻana, ua ʻano like ʻole ka pā kila, ua liʻiliʻi ke koena o ke koʻikoʻi, ʻaʻole i haki ʻia ka ʻili.ʻOi aku ka maʻalahi o ka nui a me nā kikoʻī kikoʻī o ka mānoanoa o ka pā, hiki ke hana i nā huahana nui-nui a me nā huahana liʻiliʻi liʻiliʻi, ʻaʻole wale i nā paipu kila mānoanoa me ka ikaika nui, akā ʻo ka liʻiliʻi liʻiliʻi nui- nā paipu kila pā, ʻoi loa I ka hana ʻana i nā paipu mānoanoa kiʻekiʻe, ʻoi aku ka maikaʻi o ka hana ʻana i nā paipu liʻiliʻi a me ke anawaena mānoanoa o ka paia, loaʻa iā ia nā mea maikaʻi ʻole ma mua o nā hana ʻē aʻe, a hiki ke hoʻokō i nā koi o nā mea hoʻohana no nā kikoʻī paipu kila. .Hoʻokumu ʻo UO i ke kaomi ʻana o U a me O i ʻelua mau manawa, kahi i hōʻike ʻia e He nui ka mana a me ka puka kiʻekiʻe.ʻO ka maʻamau, hiki i ka puka makahiki ke hiki i 300,000 a 1,000,000 tons, kahi kūpono no ka hana nui o kahi kikoʻī hoʻokahi.

3. humuhumu pololei kiʻekiʻe alapine (frequency resistance) welded paipu

Hoʻokumu ʻia ka paipu welded high-frequency welded straight seam (RW) ma ka hoʻohana ʻana i ka hopena ʻili a me ka hopena pili o ke alapine kiʻekiʻe e wela a hoʻoheheʻe i ka ʻaoʻao o ka paipu blank ma hope o ka hoʻokumu ʻia ʻana o ka wili wela e kahi mīkini hana, a laila. kaomi-welded ma lalo o ka hana o ka extrusion roller.
