ʻElua ʻano o nā paipu mechanical seamless

ʻO ka paipu kila maʻemaʻe ʻole kekahi o nā ʻano paipu kila ʻole.He ʻāpana hakahaka ka paipu kila ʻole a ʻaʻohe welds mai ka hoʻomaka a i ka hopena.Ke hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, ʻoi aku ka maʻalahi o ka paipu kila maʻemaʻe i ka wā e like ai ke kulou a me ka ikaika torsion, a ʻo ia ke ʻano o ke kila keʻa.

ʻElua mau ʻano o ka paipu kila mechanical seamless:

Unuhi huki ʻole (CDS) a me ka ʻōwili wela ʻole (HFS).Loaʻa ka ikaika a me ka lōʻihi o nā paipu kila CDS a me HFS, akā ʻokoʻa iki ka maikaʻi o ke kaʻina hana o kēlā me kēia ʻano paipu.ʻO ka hoʻoholo ʻana inā ʻoi aku ka maikaʻi o ka paipu maʻemaʻe huki anu a i ʻole ka paipu wela i hana ʻia ma muli o ke ʻano āu e hoʻolālā ai e hoʻohana i ka paipu no kāu noi.

Hana ʻia ka puʻupuʻu mechanical seamless i huki ʻia me ke kila kalapona SAE 1018 i ʻōwili ʻia a hoʻopaʻa ʻia i ka lumi wela.I ka wā o ka hoʻolōʻihi ʻana, hele ka piko o ka paipu i loko o ka ʻōpala.Hoʻohana ʻia ka ikaika e hoʻolōʻihi i ke kila i ka mānoanoa a me ke ʻano i makemake ʻia a hoʻomaʻamaʻa i ka ʻili.Kūlike kēia ʻano paipu kila i ka maʻamau ASTM A519.Hāʻawi ia i ka ikaika hua kiʻekiʻe, nā hoʻomanawanui kokoke a me nā papa maʻemaʻe, e lilo ia i koho mua no nā noi mechanical.
