ʻO ka hōʻoia maikaʻi o ka paipu kila pā mānoanoa i hana ʻia ma Kina
Hoʻohana nuiʻia ka paipu kila Alloy no nā pipelines kiʻekiʻe a me ka wela wela a me nā mea hana e like me ka mana mana, ka mana nuklea, ka paila kiʻekiʻe, ka superheater kiʻekiʻe a me ka reheater. Hana ʻia ʻo ia me ke kila kalapona kiʻekiʻe, ke kila structural alloy a me ke kila pale wela ma o ka ʻōwili wela (extrusion, expansion) a i ʻole ka ʻōwili anuanu (drawing). ʻO ka pōmaikaʻi nui loa o ka paipu kila kila he hiki ke hana hou ʻia 100%, e like me ka hoʻolālā aupuni o ka mālama ʻana i ke kaiapuni, ka mālama ʻana i ka ikehu a me ka mālama waiwai. Paipai ke kulekele aupuni i ka hoʻonui ʻia ʻana o ke kahua noi o ka paipu alloy kiʻekiʻe. I kēia manawa, ʻo ka hoʻohana ʻana i nā paipu alloy ma Kina he hapalua wale nō o ka huina kila ma nā ʻāina kūkulu. ʻO ka hoʻonui ʻana i ka papa noi o nā paipu alloy e hāʻawi i kahi ākea ākea no ka hoʻomohala ʻana i ka ʻoihana. Wahi a ka noiʻi ʻana o ka hui loea o ka lālā paipu huila o Kina Special Steel Association, e hoʻonui ʻia ka noi no ka lōʻihi o ka paipu alloy kiʻekiʻe ma Kina e 10-12% i kēlā me kēia makahiki i ka wā e hiki mai ana. Ua wehewehe ʻia ka paipu Alloy e like me ka paipu kila e like me ka mea hana (ie mea). E like me ka inoa i hōʻike ʻia, he paipu i hana ʻia me ka huila; Ua wehewehe ʻia ka paipu ʻole e like me ke kaʻina hana o ka paipu kila (seamless seam). ʻO ka mea ʻokoʻa mai ka paipu seamless ʻo ia ka paipu seamless, me ka paipu wili wili pololei a me ka paipu spiral.

ʻO nā paipu Alloy he mau ʻāpana hollow a hoʻohana nui ʻia e like me nā pipelines no ka lawe ʻana i nā wai, e like me nā pipelines no ka lawe ʻana i ka aila, ke kinoea maoli, ke kinoea, ka wai a me kekahi mau mea paʻa. Ke hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, ʻoi aku ka maʻalahi o ke kaumaha o ka paipu kila i ka wā e like ai kona kulou a me kona ikaika torsional. ʻO ka paipu kila Alloy he kila ʻāpana waiwai, i hoʻohana nui ʻia no ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical, e like me ka paipu ʻaila ʻaila, kaʻa hoʻoili kaʻa, ke kaʻa kaʻa a me ka scaffold kila i hoʻohana ʻia i ke kūkulu ʻana. ʻO ka hana ʻana i nā ʻāpana apo me ka paipu kila kila hiki ke hoʻomaikaʻi i ka nui o ka hoʻohana ʻana i nā mea, hoʻomaʻamaʻa i ke kaʻina hana, mālama i nā mea hana a me nā hola hana, e like me ka rolling bearing apo, jack sleeve, etc. ʻO ka paipu kila huila he mea pono nui no nā ʻano mea kaua maʻamau. Pono e hana ʻia ka pahu pū a me ka pahu i ka paipu kila. Hiki ke hoʻokaʻawale ʻia ka paipu kila i loko o ka paipu poepoe a me ka paipu ʻano kūikawā e like me ka ʻāpana cross-sectional a me ke ʻano. No ka mea, ʻoi aku ka nui o ka ʻāpana pōʻai ma lalo o ke ʻano o ke anapuni like, hiki ke lawe ʻia ka wai e ka paipu pōʻai. Eia kekahi, i ka wā e hoʻokau ʻia ai ka ʻāpana apo i ke kaomi radial i loko a i waho paha, ʻoi aku ka like o ka ikaika. No laila, ʻo ka hapa nui o nā paipu kila he paipu poepoe.
