ʻO nā paipu hoʻoheheʻe bimetallic i hoʻopau ʻia

No ka paipu finned composite, pono mākou e paipu laina——compressing or roll——strip peeling——washing——pressure test——blast blow——packaging.
Hoʻohui ʻia ka paipu Finned me ka pahu hao-alumini a i ʻole keleawe-aluminum e ʻōwili ana i ka ʻili, ʻo ia ka hulu e paʻa, liʻiliʻi ka wela wela, maikaʻi ka hoʻololi ʻana i ka wela, ikaika kiʻekiʻe, nā poho liʻiliʻi, ʻoi aku ka ikaika o ka corrosion, ʻaʻole maʻalahi i ka deformation a me kahi. lōʻihi hana ola ma ke anu a me ka wela kūlana, etc.
He laumania a ʻaʻohe burr, no laila maʻalahi ka hoʻomaʻemaʻe.He mea maʻalahi ka hoʻomaʻamaʻa ʻana i ka ʻili hope a hoʻomaloʻo i ka wai i ka wā e anuanu ai i ka wā e hoʻomehana ai i ka ʻenekinia.I ke kūlana me ka maloʻo, ka hoʻomehana a me ka hoʻololi wela ʻē aʻe, paʻa kona ʻili e ka anodizing, me ka waihoʻoluʻu nani a me ka luster, a hiki ke pale pono i ka corrosion.
Aluminum rolling finned tube e olokaa holoʻokoʻa ana e ka alumini tube, nona ka hulu ʻaʻole pili i ka pale wela, ka ikaika kiʻekiʻe, ka haʻalulu wela a me ka haʻalulu mechanical, ka hana wela maikaʻi, a me ka hoʻonui nui ʻana i ka wela.ʻO ka mea hoʻololi wela me kēia ʻano puʻupuʻu finned ma mua o ke kaula a i ʻole a puni nā pā pā.
