ʻO ka paipu kila maʻemaʻe ʻole he kiʻekiʻe ka pololei o ka paipu kila i hana ʻia e ke kaha anu a i ʻole ka ʻōwili wela. No ka mea, ʻaʻohe papa o ka oxide o nā paia o loko a me waho o nā paipu kila, hiki iā lākou ke kū i ke kaomi kiʻekiʻe me ka ʻole o ka leakage, he kiʻekiʻe kiʻekiʻe, ʻoluʻolu kiʻekiʻe, ʻaʻohe deformation i ka wā o ke kulou anuanu, ʻaʻohe hoʻonui. ʻO C, Si, Mn, S, P, a me Cr ka hui kemika o nā paipu kila pololei, i hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, ʻoi aku ka maʻalahi o ka paipu kila maʻemaʻe ke like ka ikaika o ka piko a me ka torsional. He kila cross-section waiwai i hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana a me nā ʻāpana mechanical.

ʻO nā mea maʻamau i hoʻohana ʻia no nā paipu kila maʻemaʻe ʻole he 10#, 20#, 35#, a me 45#. Nui nā mea hiki ke hana ʻia. ʻOiai ʻaʻole paʻakikī loa ke kila, hiki ke hana ʻia e like me nā pono. E like me: 10#, 35#, 16Mn, 40Cr.

ʻO ka hana a me nā hiʻohiʻona o ka paipu kila seamless
Nā hiʻohiʻona nui: ʻO nā paia o loko a me waho o ka paipu kila he kiʻekiʻe kiʻekiʻe a me ka maʻalahi. Ma hope o ka hoʻomaʻamaʻa ʻana i ka wela, ʻaʻohe papa oxidation o ka paipu kila a maʻemaʻe loa ka paia o loko. Hiki i ka paipu kila ke pale i ke kaomi kiʻekiʻe, ʻaʻole e hoʻoheheʻe ʻia i ka wā o ke kulou anuanu, ʻaʻohe māwae i ka ʻāʻī a me ka palahalaha, a hiki ke hoʻohana ʻia no nā hana paʻakikī. Deformation a me ka hana mechanical. Ka waihoʻoluʻu paipu kila: keʻokeʻo me ke kala ʻālohilohi, kiʻekiʻe metala luster.
Hoʻohana nui: nā paipu kila no nā kaʻa, a me nā mea hoʻohana me nā koi kiʻekiʻe no ka pololei a me ka maʻalahi o nā paipu kila.

ʻElua kaʻina hana maʻamau o nā paipu kila ʻole pololei: ke kaha anu a i ʻole ka ʻōwili anu
1. ʻO ka paipu kila i unuhi ʻia ma ke kaʻina hana kaha kiʻi anuanu e hana i nā ʻano lapaʻau kiʻekiʻe e hana ai i kahi paipu kila i kapa ʻia ʻo ka paipu kila liʻiliʻi.
2. ʻO ka paipu kila i huki ʻia i waho ma ke kaʻina hana ʻōwili anuanu e hana i nā ʻano lapaʻau kiʻekiʻe e hana i kahi paipu kila i kapa ʻia ʻo cold-rolled precision seamless steel pipe.

ʻO ka ʻōlelo maʻamau, inā he paipu kila liʻiliʻi liʻiliʻi a i ʻole ka paipu kila liʻiliʻi, he kiʻekiʻe ka pololei o kēia ʻano paipu kila, kahi ʻili maʻemaʻe, ʻaʻohe papa oxide ma nā paia o loko a me waho. ʻO kēia ʻano kiʻekiʻe-precision seamless kila paipu hiki ke Production, ma hydraulic cylinders a me nā huahana.
