He huahana kila koʻikoʻi ka paipu kila humuhumu i hoʻohana nui ʻia ma nā ʻano he nui. ʻO kāna kaʻina hana kūikawā e hana ai i ka paipu kila me ka ʻole o nā wili, me nā waiwai mechanical maikaʻi a me ke kūpaʻa compressive, kūpono no nā wahi me ke kaomi kiʻekiʻe a me ka mahana kiʻekiʻe.

Ma ke ʻano o nā hiʻohiʻona hoʻohana, hoʻohana pinepine ʻia nā paipu kila humuhumu ma nā kahua e like me ka halihali ʻaila a me ke kinoea, ka ʻoihana kemika, ke kūkulu ʻana, ke kūkulu moku a me ka ʻoihana kaʻa. ʻOi loa aku i ka ʻoihana ʻaila a me ke kinoea, hoʻohana pinepine ʻia nā paipu kila humuhumu no nā paipu a me nā lako downhole, a hiki ke kū i nā kūlana kaiapuni ʻino.

E pili ana i nā kūlana, hana pinepine ʻia a hoʻāʻo ʻia nā paipu kila seamless e like me nā kūlana aupuni (e like me GB, ASTM, API, a pēlā aku).GB/T 8162pili i nā paipu kila humuhumu no nā hale, ʻoiaiASTM A106hoʻohana nui ʻia no nā paipu kila kalapona no ka lawelawe wela kiʻekiʻe. No nā paipu kila kila me ka ʻole o ka huila, ʻo nā kūlana maʻamau e komo pū meASTM A335, a ʻo nā māka i koho ʻia he P5 a me P9 e hōʻoia i ka hana o nā paipu kila ma nā mahana a me nā kaomi kikoʻī.

Ma ke ʻano o nā mea hana, hoʻohana pinepine nā paipu kila humuhumu me ka ʻole o ka hao hao haʻahaʻa a me nā kila kila kiʻekiʻe, me ke kūpaʻa maikaʻi loa i ka palaho, ke kūpaʻa i ke ana wela kiʻekiʻe a me ke kūpaʻa i ka oxidation. No ka laʻana, ʻo nā mea i hoʻohana pinepine ʻia no nā paipu kila kila me ke kila kila Cr-Mo (e like me 12Cr1MoG etc.), kūpono no nā lako wela kiʻekiʻe a me ke kaomi kiʻekiʻe e like me nā paila a me nā mea hoʻololi wela. Hana ʻia kēia mau mea me ka mālama wela koʻikoʻi a me ka nānā ʻana e hōʻoia i ko lākou kūpaʻa a me ka palekana ma lalo o nā kūlana koʻikoʻi.

He mea nui nā paipu kila humuhumu ʻole, ʻoiai nā paipu kila humuhumu ʻole me ka huila, i ka ʻoihana hou. ʻO kā lākou hana maʻamau a me nā mea hana kiʻekiʻe e lilo ai lākou i koho kūpono no nā noi ʻenekinia like ʻole.
