ʻO ka paipu hoʻoheheʻe ʻole no ka paila he ʻano o ka paila paila, nona ka ʻāpana o ka paipu kila seamless. ʻO ke ʻano hana hana like me ka seamless tube, akā aia nā koi koʻikoʻi ma ke kila i hoʻohana ʻia i ka hana ʻana i ka paipu kila. Hoʻohana pinepine ʻia ka paila me ka paipu ʻole i ka wela kiʻekiʻe a me nā kūlana kiʻekiʻe, nā paipu i ke kinoea flue wela a me ka mahu wai ma lalo o ka hana, e hana ʻia ka oxidation a me ka corrosion. Pono nā paipu kila e loaʻa ka ikaika lōʻihi kiʻekiʻe, ke kūpaʻa ʻana i ka corrosion oxidation kiʻekiʻe, a me ka paʻa o ke kino. Hoʻohana nui ʻia ʻo Boiler me ka seamless tube e hana i ke kiʻekiʻe kiʻekiʻe a me ka ultra-high pressure boiler boiler superheater tube, reheater tube, gas guide boiler me seamless tube, ka pahu mahu nui, etc.

Paipu paila haʻahaʻa a me waenaGB3087-1999, paila hoʻoheheʻe ʻoleGB5310-1999hoʻohana ʻia e hana i nā ʻano hana like ʻole o ka paila haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ʻo ka paipu mahu, ka paila wai paipu a me ka locomotive boiler superheated mokumahu paipu, ka paipu uahi, ka paipu uahi liʻiliʻi a me ka paipu paipu pōhaku pōhaku o ke kila kila wela kiʻekiʻe a huki ʻia ke anu (rolled) seamless steel pipe. Paipu kila maʻemaʻe no ka hale (GB/T8162-1999) he paipu kila maʻemaʻe ʻole no ka hana maʻamau a me ke ʻano mechanical. Nā kikoʻī a me ka maikaʻi o ka helehelena:GB5310-95"Seamless Steel paipu no High puʻe boiler" wela olokaa paipu anawaena 22~530mm, paia mānoanoa 20~70mm. ʻO ke anawaena o waho o ke anu (cold rolled) tube he 10 ~ 108mm, a he 2.0 ~ 13.0mm ka mānoanoa o ka pā. ʻO ka paipu kila maʻemaʻe keʻano kūikawā he huaʻōlelo maʻamau no ka paipu kila maʻemaʻe o nā ʻano ʻāpana keʻa ʻē aʻe koe ka paipu poepoe. E like me ka like 'ole kino a me ka nui o ke kila paipu pauku, e hiki ke maheleia i like paia mānoanoa kūikawā-like seamless kila paipu (code no D), unequal pā mānoanoa kūikawā-like seamless kila paipu (code no BD), loli anawaena kūikawā-like seamless kila paipu (code no BJ). Hoʻohana nui ʻia nā paipu kila seamless kūikawā i nā ʻāpana like ʻole, nā mea hana a me nā ʻāpana mechanical. Ke hoʻohālikelike ʻia me ka puʻupuʻu poepoe, ʻoi aku ka nui o ka manawa o ka inertia a me ka modulus ʻāpana o ka pahu kūikawā, a ʻoi aku ka nui o ka hiki ke pale aku i ka piko a me ka torsion, hiki ke hōʻemi nui i ke kaumaha o ka hale a mālama i ke kila. 4. Ho'āʻo hoʻohui kemika (1)GB3087-82ʻO ka "paipu kila maʻemaʻe no ka paila haʻahaʻa a me ka haʻahaʻa". ʻO ke ʻano hoʻāʻo hoʻohui kemika e like me GB222-84 a me GB223 "Steel and Alloy Chemical Analysis Method" ka ʻāpana kūpono.
