ʻO ke paipu kila humuhumu kalapona e pili ana i kahi paipu i hana ʻia me ke kila kalapona me ka ʻole o nā hui a i ʻole nā humuhumu i hoʻopaʻa ʻia, a ua hoʻopuka ʻia kahi billet paʻa ma o kahi die e hana i kahi paipu o ke ʻano a me ka nui i makemake ʻia. He mea kaulana ka paipu kila humuhumu kalapona no kona kūpaʻa kupaianaha, ka ikaika tensile a me ke kūpaʻa ʻana i ka pala, e kūpono ana no nā ʻano ʻoihana like ʻole me ka ʻaila a me ke kinoea, nā kaʻa a me ke kūkulu ʻana.
ʻO kekahi o nā papa kaulana loa o ka paipu kila humuhumu kalaponaPapa B A106, ʻo ia ke kūlana ASTM no ka paipu kila kalapona seamless no ka lawelawe wela kiʻekiʻe. Loaʻa iā ia ka nui o ke kalapona he 0.30%, e kūpono ana no nā noi e pono ai ke mahana kiʻekiʻe a me ke kaomi. He kūpono hoʻi ia no nā noi haʻahaʻa a me nā mahana haʻahaʻa, a me ka hoʻoheheʻe ʻana a me ka brazing.
ʻO kekahi papa kaulana ʻē aʻePapa API 5L B, ʻo ia ke kūlana maʻamau no ka paipu kila seamless a welded no nā ʻōnaehana hoʻoili pipeline ma ka ʻoihana aila a me ke kinoea. Loaʻa iā ia ka nui o ke kalapona he 0.30%, e kūpono ai no ka hoʻohana ʻana i nā wahi lawelawe kiʻekiʻe a me ke kiʻekiʻe o ka mahana.
Ma waho aʻe o ke ʻano, he mea nui loa hoʻi ka mea o ka paipu kila humuhumu kalapona. ʻO nā mea maʻamau e komo pū me SAE 1020, nona ka ʻike kalapona haʻahaʻa a kūpono no ke kulou ʻana, ka flanging a me nā hana hoʻokumu like, a me SAE 1045, nona ka ʻike kalapona kiʻekiʻe a kūpono no nā noi e pono ai ka paʻakikī, ka paʻakikī a me ke kūpaʻa i ka ʻaʻahu.
ʻO nā mea ʻē aʻe e komo pū ana me ASTM A519 Grade 4130 no nā laina hydraulic kiʻekiʻe a me nā paipu ʻaila, a me ASTM A106 Grade C me ka nui o ke kalapona o 0.35% no nā noi e koi ana i ke kūpaʻa kiʻekiʻe i ka pala.
I ka hopena, he mea nui nā paipu kila wili kalapona i nā ʻano ʻoihana like ʻole a ʻo ke koho ʻana o ka papa a me nā mea e pili ana i ka noi kikoʻī. ʻO A106 Papa B a me API 5L Papa B nā papa kaulana, ʻoiai nā mea e like me SAE 1020, SAE 1045,Papa ASTM A519 4130, a me ASTM A106 Papa C he mau koho kaulana.
